10 Window Replacement Tips for Northern Colorado Homeowners

When a Northern Colorado storm rolls in, your windows often take the first hit. From pounding hailstones to relentless winds, and the daily cycle of temperature swings and UV rays, the region’s weather can turn small window problems into costly headaches. For homeowners in Brighton, Longmont, Thornton, and the Greater Denver area, replacing aging or damaged windows isn’t just about aesthetics—it’s a matter of energy efficiency, safety, and peace of mind.

Yet, the path to new windows is lined with decisions that can feel overwhelming. Which products actually stand up to Colorado’s extremes? How do you make sense of energy ratings, code requirements, or the range of materials on the market? And when the up-front investment is significant, how can you be sure you’re making the best choice for your home and your budget?

This guide is designed to bring clarity to the window replacement process, starting with practical ways to assess your current windows and moving through every key decision—measurement, product selection, code compliance, and finding a trustworthy local installer. Along the way, you’ll discover financial incentives, maintenance tips, and expert insights tailored to the realities of Colorado living. Whether you’re tackling a single drafty window or planning a whole-home upgrade, the following ten tips will help you navigate the process confidently and avoid common pitfalls.

Let’s get started—your next step to a safer, more comfortable, and energy-smart home begins here.

1. Evaluate Damage and Determine if Replacement is Necessary

Before investing in new windows, take the time to inspect your existing units from inside and out. A thorough evaluation helps you pinpoint problem areas, document damage for insurance or warranty purposes, and decide whether a simple repair will suffice or if you need a full window replacement. In Northern Colorado, where hailstorms and temperature swings are common, small issues like seal failures can quickly lead to bigger problems—moisture intrusion, mold growth, or rising energy bills. Starting with a methodical assessment ensures you only expend time and money where it’s truly needed.

Armed with a flashlight and a few basic tools, you can conduct an initial self-inspection in under an hour. For example, holding a lit candle or incense stick close to the frame on a windy day lets you watch the smoke’s movement—any flicker or pull means air is leaking through. As you go, snap clear photos of cracked glass, warped frames, or peeling sealant. Those images will not only help you decide on next steps, they’ll also support any insurance claims down the road.

Inspect for Visible and Hidden Damage

Start by examining every inch of the window unit:

• Photograph and note any broken panes, dents from hail, or gaps in the sealant bead.


• Check interior sills and tracks for water stains, rot, or debris that can trap moisture.


• Inspect the exterior frame lines for cracks in caulk, peeling paint, or warping of the sash.


• Look for hidden issues, like mold growth tucked behind trim or condensation between panes that signals a failed insulating seal.

Keeping a damage log—photos with dates and brief descriptions—can be invaluable when discussing repairs with a contractor or filing an insurance claim.

Assess Energy Loss and Drafts

Visible damage is only part of the story. Drafts and heat loss can lurk where you least expect them:

• Draft test: On a windy day, move a lit incense stick or thin ribbon along the window perimeter. Any noticeable drift indicates an air leak.


• Infrared thermometer: Run the scanner around edges and corners; temperature dips confirm where cold outdoor air is penetrating.


• Professional blower-door test: If you suspect multiple leaks throughout the home, hire a certified technician to pressurize your house and map out air infiltration.

Compare your findings to homeowner comfort levels and energy costs. If you’re already seeing condensation, feel cold drafts, or notice a spike in heating bills, those are strong signals that repair may not solve the underlying insulation failure.

Decide Between Repair vs. Full Replacement

Once you know the scope of the damage and energy loss, weigh your options:

Factor	Repair	Full Replacement
Up‐Front Cost	Lower—often just sealant, glass, or trim	Higher—new frame, sash, and insulated glass
Remaining Lifespan	Short extension (3–5 years)	Long-term performance (20+ years)
Energy Efficiency	Limited gains	Significant reduction in heating/cooling
Aesthetic Impact	Matches existing profile	Opportunity to upgrade style and layout

Quick decision checklist:

• If damage is confined to one pane or minor rot around the sill, and energy loss is minimal, repair can be cost-effective.


• If multiple panes have failed seals, frames are warped or rotten, or drafts persist after repairs, replacement is the smarter investment for lasting comfort and efficiency.


• Factor in local weather exposure—windows battered by hail or UV degradation often benefit more from a full-replacement approach with modern, impact-resistant materials.

2. Measure Your Windows Accurately Before Ordering

Don't rush through measurements. Even a slight error can lead to gaps, leaks, or the need to reorder—especially in Northern Colorado’s freeze-thaw climate. Set aside time, gather the right tools, and follow a systematic approach. Accurate dimensions are the key to a smooth installation and properly fitting windows.

Essential measurement tools:

• Tape measure (25 ft or longer)


• Small level or straightedge


• Pencil and paper (or a notes app)


• Camera or smartphone for reference photos


• Optional: angle finder or protractor (for sill pitch)

With everything on hand, you’ll capture every critical dimension with confidence.

Measure Width and Height in Multiple Places

Begin by measuring the frame’s interior width in three spots: top, center, and bottom. Note the smallest measurement—this compensates for any settling or irregular framing. Then measure the interior height at the left jamb, center, and right jamb, again recording the smallest number. These “tight” dimensions ensure your replacement unit will slide right into the opening without force.

Steps:

1. Width: inside-to-inside at head, midpoint, and sill.


2. Height: sill to head jamb at left, center, right.


3. Use the smallest width and height for ordering.

Verify Frame Squareness and Sill Slope

A square frame ensures smooth operation and proper sealing. Measure the diagonals from corner to corner; the two readings should match within about 1/8 inch. If there’s a larger discrepancy, shimming or a custom-sized window may be necessary.

Next, capture the sill slope with an angle finder or protractor. Replacement sills often come pre-pitched, so matching your existing angle (usually a 2–3° pitch) prevents water ponding against the frame.

Checklist:

• Squareness: diagonal measurements within 1/8 inch.


• Sill slope: record the exact pitch.

Record, Double-Check, and Communicate Dimensions

Compile your measurements into a simple table or spreadsheet and label each window by location (e.g., “Living Room – South Wall”). Take photos of the tape measure in place and annotate them if possible. Before placing your order, send the full data package to your supplier or installer and ask them to confirm the figures. Clear communication at this stage avoids costly mix-ups and keeps your project on track.

Best practices:

• Clearly label each dimension by room and wall orientation.


• Annotate reference photos with measurement notes.


• Review every entry before submission.

By investing a little extra time in precise measurement and documentation, you’ll set the stage for a hassle-free installation and windows that fit perfectly from day one.

3. Understand Local Building Codes and Egress Requirements for Safety

Upgrading your windows is more than a curb-appeal project—it’s a critical safety upgrade that affects everything from family well-being to your home’s resale value and insurance rates. In Colorado, building under the International Residential Code (IRC) helps ensure that every bedroom has at least one egress window for emergency escape and rescue. Skipping these requirements can lead to costly corrections, failed inspections or even voided insurance claims.

The key reference for emergency escape and rescue openings is IRC Section R310. It lays out minimum dimensions and operating methods so firefighters or your own family can get in and out quickly if there’s ever a fire or other emergency. Familiarizing yourself with these rules up front keeps your project on schedule and guarantees that your new windows meet or exceed local regulations—no surprises at final inspection.

Review Emergency Escape Opening Specifications

Under IRC R310, each egress window must provide:

• A minimum net clear opening of 5.7 square feet (5.0 sq ft for grade-floor windows).


• At least 20 inches of clear width and 24 inches of clear height.


• A maximum sill height of 44 inches above the finished floor.


• Tool- and key-free operation from the inside, so anyone can unlatch or slide open without special devices.

When you shop for replacement units, check the manufacturer’s NFRC or product spec sheet for “net clear opening” values. If you plan to enlarge an existing rough opening, confirm that the rough-opening dimensions match or exceed the net clear numbers after framing and finished materials are in place.

Ensure Proper Window Well and Area Well Dimensions

If your egress window sits below grade, you’ll need an area well outside to provide clearance for escape:

• The well must offer at least 9 sq ft of total horizontal area, with a minimum 36-inch width and 36-inch projection from the foundation wall.


• Any well deeper than 44 inches needs a fixed ladder or steps spaced no more than 18 inches apart, so occupants can climb out safely.

Failing to size the well correctly can mean no legal egress—regardless of your new window’s opening dimensions. Work with your installer to confirm the well layout, or consult a site-prepared sketch before ordering custom windows.

Reference Authoritative Code Guidance

Building codes can vary from county to county in Northern Colorado, so always double-check local amendments before finalizing product specs. For a thorough run-down of recent changes, see the ICC’s article on Significant Changes to the 2018 International Residential Code. Then reach out to Brighton, Longmont, or Weld County building departments to confirm any local tweaks—especially if you’re in a historic district or planned community with additional design guidelines.

4. Choose Energy-Efficient Windows Tailored to Northern Colorado Climate

Northern Colorado’s mix of cold winters, hot summers, and intense UV exposure puts a premium on well-insulated, high-performance windows. Choosing the right energy-efficient products not only slashes heating and cooling bills but also minimizes condensation, protects interiors from sun damage, and keeps your home comfortable year-round. Understanding how pane counts, gas fills, low-E coatings, and solar heat gain ratings interact with our local climate will help you get the most from your investment.

Select Appropriate Pane Count and Gas Fill

Most homeowners start with double-pane windows, which sandwich two glass layers around an argon-filled cavity to slow heat transfer. Argon gas is cost-effective, stable over time, and significantly boosts R-values compared to air. If you’re looking for top-tier performance—especially for north-facing rooms or high-altitude properties exposed to stronger UV—you might consider triple-pane units. The extra pane and gas layer (often argon or the denser krypton) deliver better insulation and sound control, though at a higher upfront cost. For common living spaces, double-pane argon windows hit the sweet spot; for bedrooms or rooms with extreme temperature swings, triple-pane krypton windows offer maximum comfort and minimal heat loss.

Evaluate Low-E Coatings and Solar Heat Gain Coefficient

Low-emissivity (low-E) coatings reflect infrared heat while admitting visible light, enhancing winter warmth and reducing summer glare. In colder climates like ours, look for a coating on the inner glass surface to trap heat indoors, and a moderate Solar Heat Gain Coefficient (SHGC) around 0.30–0.40 to capture beneficial winter sun without overheating in summer. If your home has large sunny exposures—east or west facades—consider products with a lower SHGC (0.25 or less) to cut down on UV fading and run-up in AC costs. Every window spec sheet will list these metrics, so aim for U-factors of 0.25 or lower alongside the SHGC that best matches your sun-angle and room usage.

5. Explore Financial Incentives, Rebates, and Tax Credits

Replacing windows represents a sizable investment, but federal and state programs can offset a significant portion of your cost. By tapping into available tax credits, utility rebates, and local incentives, Northern Colorado homeowners can lower their net out-of-pocket expense and accelerate the payback on energy-saving upgrades. Here’s how to make the most of these opportunities.

Federal Tax Credits under the Inflation Reduction Act

The Inflation Reduction Act (IRA) provides a 30% tax credit on qualifying energy-efficient improvements—including ENERGY STAR certified windows—up to $600 per year through 2032. To claim your credit:

1. Purchase windows that meet the “Most Efficient” criteria under ENERGY STAR.


2. Keep all manufacturer’s certifications and ENERGY STAR labels showing U-factor and SHGC ratings.


3. Complete IRS Form 5695(Residential Energy Credits) when you file your federal return.


4. Attach the form and include the credit on your 1040 line for non-refundable energy credits.

This credit directly reduces your tax liability, dollar for dollar. If your annual tax bill is less than $600, you won’t receive a refund for the unused portion, so plan to stagger window replacements over multiple years if you have a large project.

Colorado-Specific Energy Incentives and Rebates

Beyond the federal credit, Colorado offers its own suite of programs to reward energy-efficient home improvements:

• Statewide Rebates: The Colorado Energy Office maintains guides to federal and state incentives—see their comprehensive overview at
  
  https://energyoffice.colorado.gov/federal-tax-credits-incentives-homes


• Utility Rebates: Many local providers, such as Xcel Energy, Platte River Power Authority, and Black Hills Energy, run rebates for ENERGY STAR window installations.


• Local Grants and Programs: Some counties and municipalities offer additional rebates or zero-interest financing for qualified upgrades.

Rebate amounts and application processes vary by provider. Always confirm deadlines and program budgets—some utility rebates are issued on a first-come, first-served basis.

Tips for Documenting and Claiming Credits

Clean, organized documentation is your best friend when pursuing incentives:

• Photograph Labels: Before installation, snap clear photos of the ENERGY STAR and NFRC stickers on each window. Label the shots with room names (e.g., “Guest Bedroom – NW Wall”) so you can match certificates to invoices.


• Save Invoices and Certifications: Keep original receipts, manufacturer certifications, and any rebate pre-approval forms in a dedicated folder or digital file.


• Log Installer Details: Note the installer’s name, license number, and the exact product model. Some programs require proof that certified contractors performed the work.


• Track Application Deadlines: Create calendar reminders for rebate submissions and tax-credit filings. Missing a deadline can mean forfeiting hundreds of dollars in savings.

By layering federal credits with state and utility rebates—and by maintaining meticulous records—you’ll reduce your net investment and maximize the return on your window replacement project.

6. Select the Right Frame Material and Window Style for Durability

Colorado’s hailstorms, fierce sun, and wide temperature swings demand windows built to last. Picking the right frame material and operating style not only shields your home from the elements but also cuts down on upkeep, protects against damage, and keeps your warranty intact. Focus on options that resist dents, won’t warp in heat, and stand up to constant UV exposure—so you can spend weekends enjoying your view, not repairing it.

Compare Frame Materials: Wood, Vinyl, Fiberglass, Composite

Each frame type has its strengths and trade-offs. Use the table below to match material characteristics with your priorities—whether that’s insulation value, ease of care, or long-term durability in Northern Colorado’s unique climate.

Material	R-Value	Maintenance	Cost Range	Customization
Wood	High (3.0–5.0)	Requires repainting or staining every 5–7 years	$$–$$$	Unlimited paint/stain options; natural aesthetics
Vinyl	Moderate (2.0–3.5)	Virtually no maintenance; won’t rot or corrode	$–$$	Limited color palette; cannot be painted
Fiberglass	High (3.5–5.0)	Minimal upkeep; stable under temperature swings	$$–$$$	Factory finishes; some color choices
Composite	High (3.0–5.0)	Low maintenance; engineered to resist hail impact	$$$	Wide color and texture options; DIY-friendly

• R-Value: Higher numbers slow heat transfer in winter and block solar gain in summer.

• Maintenance: Consider how often you want to repaint or inspect seals.

• Cost: Factor in the material plus any specialty finishes (e.g., impact-resistant cladding).

• Customization: Check lead times—special colors or wood grains may take 8–12 weeks to deliver.

Choose Window Styles for Ventilation and Seal

The way a window opens affects both airflow and weatherproofing. Here’s how common styles stack up:

• Double-Hung: Two operable sashes slide up and down. Great for cleaning (tilt-in models), but can admit drafts if seals wear.


• Casement: Hinged at the side, crank-open sashes clamp tightly onto the frame for an excellent seal. Ideal for windy sites and minimal air infiltration.


• Awning: Hinged at the top, these open outward to keep rain out while letting fresh air in. Perfect over kitchen sinks or basement openings.


• Sliders: One sash glides horizontally. Low-profile and easy to operate, but seal quality varies by hardware.

In high-wind or hail-prone areas, prioritize casement or awning windows—they lock firmly and shed stormwater. If ease of maintenance tops your list, double-hung windows with tilt-in sashes simplify glass cleaning from inside.

Evaluate Aesthetic and Custom Design Options

Beyond performance, your windows should complement your home’s character. Semper Fi Restoration offers:

• Grid patterns: Colonial, prairie, and custom layouts between the glass cut down on cleaning chores.


• Color finishes: Exterior hues rated to resist UV fading, plus interior shades to match your décor.


• Specialty shapes: Arches, trapezoids, or full-height picture windows for architectural flair.

Keep in mind that custom designs and non-standard shapes often require extended lead times. Plan ahead—especially if you’re coordinating with painting or siding work—to ensure your new windows arrive when you need them.

7. Read NFRC Labels, Compare Options, and Secure the Best Value

When you’re evaluating window products, the little NFRC label tucked in the corner of each pane is your best friend. These stickers carry standardized performance metrics that let you compare apples to apples, whether you’re looking at vinyl sliders or wood-clad casements. Rather than relying on marketing claims or broad efficiency categories, use the numbers on the NFRC label to zero in on the exact U-factor, Solar Heat Gain Coefficient, and Visible Transmittance values. From there, you’ll be able to balance thermal performance, daylighting, and cost to find the window that delivers maximum comfort and long-term savings for your Northern Colorado home.

Decode NFRC Ratings: U-factor, SHGC, and Visible Transmittance

On every NFRC label you’ll see a set of three critical figures:

• U-factor measures the rate of heat loss through the entire window assembly. Aim for a U-factor of 0.25 or lower in Northern Colorado—this keeps your home warmer in winter and minimizes ice buildup at the sill.


• Solar Heat Gain Coefficient (SHGC) indicates the fraction of solar radiation admitted as heat. A mid-range SHGC (around 0.30–0.40) captures beneficial winter sun without overheating in summer. For east- or west-facing windows, you may choose a lower SHGC (around 0.25) to reduce glare and UV damage.


• Visible Transmittance (VT) shows how much natural light passes through. A higher VT (above 0.50) brightens interiors, but if you’re sensitive to glare or own UV-prone artwork, you might accept a slightly lower VT in exchange for better solar control.

By focusing on these numbers instead of brand reputations or price tags alone, you’ll ensure each window’s performance matches your home’s orientation, insulation needs, and daylighting goals.

Verify ENERGY STAR Certification and Climate Zone Suitability

Even with strong NFRC numbers, you want windows officially rated for Colorado’s climate. ENERGY STAR certification guarantees that a product meets rigorous efficiency standards in your specific zone. Use the ENERGY STAR Product Finder to filter by our region’s requirements—Northern and North-Central Colorado reside in the colder categories, so look for windows labeled for “Northern” or “North-Central” zones. A true ENERGY STAR window will carry both the NFRC and ENERGY STAR logos on its certification sheet. That double stamp means the unit not only performs in the lab but will deliver real-world savings and comfort where you live.

Shop Smart: Obtain Multiple Quotes and Review Warranties

Securing the best value means shopping strategically. Start by requesting three or more itemized quotes that detail brand, model, frame material, glass package, and performance metrics. Compare not just the bottom-line price, but the full scope of:

• Product warranty: Look for at least 10 years on the frame and glass seals, with longer coverage (up to “lifetime”) on select brands.


• Installation warranty: Ensure the contractor stands behind their workmanship for a minimum of one year, ideally up to five years.


• Performance assurances: Some manufacturers offer payback guarantees or projected energy-savings estimates—review these commitments carefully.

With each bid in hand, lay out the numbers side by side. A slightly higher initial investment can pay dividends if it comes with a stronger warranty, better U-factor, or reduced maintenance needs. By decoding labels, confirming certifications, and comparing offers head-to-head, you’ll lock in windows that deliver maximum efficiency, durability, and long-term value for your Northern Colorado home.

8. Hire a Qualified Local Installer and Schedule Your Project

Choosing the right windows is only half the equation—proper installation seals the deal on performance, energy savings, and warranty protection. A certified, experienced installer will ensure your new frames are level, plumb, and tightly sealed, preventing leaks or drafts that can undermine even the best products. In Northern Colorado’s demanding climate, cutting corners on installation can mean wind-driven rain under loose flashing, failed seals in freeze-thaw cycles, or impact damage from hail. By hiring a vetted local pro, you lock in workmanship guarantees and preserve manufacturer warranties, so your investment pays off year after year.

Verify Contractor Credentials and Company Background

Before signing a contract, confirm the installer’s qualifications:

• License and insurance: Ask for a copy of their Colorado contractor’s license and proof of liability insurance and worker’s compensation.


• Veteran-owned status: Semper Fi Restoration’s roots in Marine Corps values translate to integrity and discipline on every job—details on their About Us page.


• Professional affiliations: Look for Better Business Bureau ratings, trade-association memberships, or manufacturer certifications (e.g., Andersen, Pella).


• References and reviews: Request recent homeowner referrals, and scan online reviews for comments on timeliness, cleanliness, and responsiveness.

A reputable contractor will welcome these checks and provide documentation upfront, rather than treating them as red flags.

Consider Northern Colorado Service Areas and Local Expertise

Local climate quirks—from the Front Range’s afternoon storms to high-altitude UV exposure—demand installers who know the region. Semper Fi Restoration serves Brighton, Thornton, Longmont, Broomfield, Erie, Westminster, and the Greater Denver metro, so they’re familiar with county building codes, HOA guidelines, and the best window packages for neighborhoods across Northern Colorado. If you’re in Longmont, their Longmont service page details area-specific offerings and showcases recent projects in your backyard. Working with a contractor who lives and works here means faster response times, clear communication, and a team that treats your home like their own.

Coordinate Scheduling to Match Lead Times and Weather

Windows—especially custom, high-performance models—typically require 6–12 weeks from order to delivery. Combine that with weather considerations, and a well-timed schedule becomes critical:

• Order early: Place orders at least three months before peak seasons.


• Avoid hail season: In Northern Colorado, late spring through midsummer sees the most hail; try to complete installations by late April or wait until late summer.


• Plan around freeze-thaw: Exterior sealants don’t adhere reliably in sub-freezing conditions, so winter installs can risk seal failure or voided warranties.

Your installer should walk you through the projected timeline and alert you to any potential delays—keeping you informed every step of the way. With clear credentials, local know-how, and a realistic schedule in hand, you’ll be set for a smooth installation and windows that stand up to Colorado’s toughest tests.

9. Prepare Your Home for a Seamless Installation Day

A smooth installation starts long before the first window is lifted through an opening. By taking a few simple steps to clear the work area, protect your belongings, and coordinate with your installers, you’ll cut down on surprises, speed up the project, and minimize the risk of damage or delays. Here’s how to get your home ready so that installation day goes off without a hitch.

Clear the Work Area and Protect Valuables

Begin by removing anything that might get in the way—or get damaged—during installation. Take down curtains, blinds, artwork, and fragile décor within arm’s reach of every window that’s being replaced. Pack small items in boxes or move them to another room. Lay down drop cloths or old sheets on floors and furniture to catch dust, debris, and any drips of sealant or paint. If you have rugs in the installation zone, roll them up and store them safely; hardwood floors and new carpeting can be especially vulnerable to scratches and stains.

For larger furniture pieces that sit against the walls, consider shifting them toward the center of the room or into a nearby space altogether. An empty work zone gives installers the freedom to maneuver ladders, toolboxes, and replacement units without tripping over chairs or coffee tables. It also lets them focus on their job instead of dodging obstacles.

Provide Access and Follow Safety Protocols

Installation crews work most efficiently when they can move freely in and out of your home. Make sure exterior pathways are clear of snow, ice, or landscaping. If you have a gate or security system, leave a code or arrange for someone to greet the team at the front door. Don’t forget to secure curious pets and keep children out of the work zone—tools and glass aren’t a combination you want your family to encounter.

Before your installers arrive, turn off any alarms or doorchime notifications that might slow down entry. If your home has smart locks or security cameras, let your installer know how to navigate them safely. Agree on a staging area—such as a driveway or garage—where new windows can be unloaded, organized, and prepped without blocking pathways or creating hazards.

Communicate Special Requirements to Installers

Every home has its quirks, and yours may need a bit of extra care. If your house was built before 1978, lead-based paint might be present on window frames. Ask your installer to follow lead-safe work practices—containment, careful removal, and proper cleanup—to protect your household and comply with EPA guidelines. Likewise, mention any tight or unusual access points: narrow hallways, steep staircases, or second-floor windows that require special lifting equipment.

Finally, share any last-minute details that could affect the job. Are there delicate window seats you want left in place? Do you prefer installers to use a particular hallway entrance? Clear, upfront communication builds trust and keeps everyone on the same page—so your windows get replaced efficiently, and your home stays in great shape.

10. Establish a Maintenance Routine to Extend Window Lifespan

Investing in high-quality windows is only half the battle—regular maintenance keeps them performing at peak efficiency, preserves curb appeal, and ensures your warranties remain valid. A proactive upkeep schedule helps you spot small issues before they become major repairs and lets you enjoy your beautiful new windows for decades.

Regularly Clean and Inspect Frames, Seals, and Hardware

At least once every three months, wipe down frames, sills, and tracks with a soft cloth and mild soap solution. This removes grit, pollen, and debris that can scratch finishes or clog drainage channels. Rinse thoroughly with clean water and dry all surfaces to prevent mold or mineral deposits.

Twice a year (spring and fall), conduct a closer inspection:

• Check sealant lines around the glass for cracks, shrinkage, or peeling.


• Exercise locks, latches, and cranks—look for stiffness or misalignment.


• Examine weatherstripping for tears or compression that might allow drafts.


• Lubricate moving parts with a silicone-based spray to keep hardware operating smoothly.

Catching loose seals or binding mechanisms early preserves your home’s comfort and prevents energy loss.

Re-Caulk and Touch-Up Paint as Needed

Caulk and paint are your windows’ first line of defense against moisture and UV damage—and both will age under Colorado’s intense sun and temperature swings. Every couple of years, scan your exterior frames for gaps or splits in the caulking bead. Remove any deteriorated material and apply a high-quality, exterior-grade silicone or polyurethane caulk for a weathertight bond.

Inspect painted or stained surfaces on wood and composite frames. If you spot flaking, blistering, or bare spots, sand back to a firm edge, prime if needed, then repaint or re-stain to match. Timely touch-ups stop water infiltration and keep frame materials protected.

Schedule Professional Check-Ups and Warranty Service

An annual exterior assessment by a qualified installer ensures your windows continue to meet performance expectations—and it often satisfies warranty requirements. After spring hailstorms or fall freeze-thaw cycles, enlist your contractor to examine flashing, inspect seal integrity, and confirm that impact-resistant features remain uncompromised.

Should you discover fogging between panes, hardware failures, or seal leaks, report them right away. Most manufacturers impose time limits on warranty claims, so having organized records—photos, date-stamped inspection notes, and installation documents—will streamline any repair or replacement process under warranty.

By sticking to a simple maintenance routine—cleaning, inspecting, re-caulking, and scheduling annual tune-ups—you’ll protect your investment and keep your home comfortable, efficient, and storm-ready for years to come.
