Precision Exteriors Restoration is a licensed exterior contractor in Denver, Colorado (Colorado License #0248041) providing residential window services across the Denver Metro and Colorado's Front Range, window replacement, window repair, new window installation, and 24-hour emergency window response following storm damage or sudden glass failure. Founded in 2016, we bring 20+ years of combined experience and 3,000+ completed exterior projects to every window assessment.

Windows on Colorado's Front Range operate under conditions that accelerate failure faster than most other markets in the country. At Denver's elevation, 5,280 feet, with surrounding communities reaching higher, UV intensity runs approximately 25 percent above sea level, accelerating frame degradation and insulated glass unit seal breakdown over time. Colorado's seasonal temperature range swings from sub-zero winter lows to glass-surface temperatures exceeding 130 degrees F on south and west exposures in summer, creating chronic thermal cycling stress on every window component. And the Front Range's position in Hail Alley means sudden glass breakage, frame damage, and seal failure from storm impact are year-round risks, not rare events.

In 2024, we responded to window damage calls alongside roofing and siding damage across Denver, Aurora, and Montbello following that season's major hail events. In 2025, we continued exterior restoration work across Aurora and Denver. We have been a Denver-based, Denver-focused exterior contractor every hail season since 2016, which means we understand how this specific climate degrades window systems, and how to assess them accurately. We are an Owens Corning Preferred Contractor and CertainTeed Shingle Master Installer. BBB A+ Accredited. NRCA member. All window work is backed by a 10-year workmanship warranty. Free inspections, no obligation.

Every window project begins with a free inspection. We assess the full window system, frame condition, seal integrity, glass unit performance, flashing integration, exterior casing, and weatherstripping, before recommending a path forward. We do not recommend replacement when repair restores performance.

Built for the Front Range

Why windows fail faster in Colorado

Direct answer: Denver windows face high-altitude UV, severe thermal cycling, low humidity, and Hail Alley impact. Understanding the specific failure modes in this climate helps Denver homeowners recognize problems early, before a minor repair becomes a window replacement project.

25% more UV

IGU seal failure from thermal cycling: at altitude, the gas fill expands and contracts repeatedly, fatigues the edge seal, and you see fogging, cloudiness, or a milky film between the glass. South and west-facing windows fail first.

300 sun days

UV-accelerated frame degradation: Colorado's 300 days of annual sunshine yellow vinyl frames, dry weatherstripping, and create draft conditions often misdiagnosed as failed glass units when the actual failure is at the frame.

7 to 9 per year

Hail and debris impact: the Front Range averages 7 to 9 significant hail events annually, common in Aurora, Thornton, and the northeast Denver suburbs, shattering glass, cracking frames, and denting aluminum cladding.

Hail and storm damage in the Denver area inspected by Precision Exteriors Restoration Storm damage, Denver metro

Altitude-specific IGU pressure issues

At Denver's elevation, the atmospheric pressure acting on window glass is lower than at sea level. IGUs manufactured and sealed at lower elevations arrive in Denver with internal gas pressure calibrated for sea-level conditions, which means the sealed gas chambers bow outward slightly at altitude. Over time, this pressure differential stresses seals prematurely. Windows manufactured, distributed, and sealed for Front Range elevation perform better over time than those shipped from lower-altitude factories without altitude adjustment. This is a real differentiator in the Denver window market, and one that homeowners rarely hear explained clearly.

Hail damage to windows is frequently underclaimed in storm damage assessments: adjusters commonly scope only visibly broken glass while missing frame damage, cracked exterior casing, and screen destruction that collectively constitute functional damage eligible for coverage.

Colorado window code

Colorado's new window law: what Denver homeowners need to know

Direct answer: As of January 2026, Colorado House Bill 23-1161 requires all residential window, door, and skylight replacements on structures three stories or lower to meet ENERGY STAR certification for the Northern climate zone. If you are replacing windows on your Denver Metro home in 2026 or beyond, this is not optional, it is a legal requirement.

For Denver homeowners, the law creates a practical complication. Colorado's Northern climate zone ENERGY STAR requirements specify U-factor and solar heat gain coefficient (SHGC) thresholds that are challenging to meet at altitude. At 5,280 feet, insulating glass units face the pressure differential issue described above, many IGU configurations that use capillary tubes to equalize pressure cannot achieve the low U-values required under Energy Star 7.0 without argon gas fill, and capillary tubes compromise the gas seal. The result is that not every window that carries an ENERGY STAR label on the box will perform correctly at Denver's elevation.

We source and install windows that meet both the HB 23-1161 compliance requirement and the altitude performance realities of the Front Range. If you have received a proposal from another contractor that does not address this requirement, or does not address altitude-rated IGU performance, that is worth asking about before committing.

Window replacement Denver

Window replacement in Denver, done right the first time

Direct answer: Window replacement Denver is warranted when insulated glass unit seals have failed, frames have deteriorated beyond repair, hail or debris has broken glass or damaged frames beyond restoration, or when upgrading to higher-performance units for thermal, acoustic, or compliance reasons.

Colorado-specific replacement considerations include altitude-rated IGU products, Low-E glass coatings calibrated for Colorado's solar gain balance, double vs. triple pane decision-making based on home orientation and elevation, and HB 23-1161 ENERGY STAR compliance for all 2026 and beyond replacements. For the full breakdown of double vs. triple pane comparison for Colorado, U-factor and SHGC guidance, hail damage documentation, insurance claim support, cost context, and what the replacement process covers, see our dedicated window replacement in Denver guide.

Three more window paths, scoped to what your home actually needs

Window repair

Window repair addresses failed seals in insulated glass units where frame condition warrants unit-only replacement rather than full frame swap, hardware failures, locks, operators, balances, cranks, frame damage from wood rot or minor physical impact, and weatherstripping and flashing failures at window perimeters. Not every fogged or drafty window requires full replacement. When the frame is structurally sound and the failure is contained, repair is a cost-effective path. The key diagnostic question is whether the frame integrity justifies preserving it, we assess that directly during inspection rather than defaulting to either repair or replacement. See full Window Repair details → Includes: IGU-only replacement process, hardware repair specifics, weatherstripping replacement, draft diagnosis, and when repair stops making sense.

Window installation

New window installation covers projects where windows are being added to an existing wall or where rough openings are being modified for different unit sizes, home additions, egress conversions, remodel projects adding light or ventilation to existing spaces. New installation involves more structural scope than replacement-in-kind: correct header sizing, framing modification, rough opening construction, full flashing and air sealing integration with the wall assembly, and building permit coordination. It is a fundamentally different scope from window replacement, with different cost, timeline, and structural requirements. See full Window Installation details → Includes: rough opening requirements, egress window code specifications, permit process, structural scope, and what new installation vs. replacement-in-kind involves.

Emergency window services

Hail impacts, debris strikes, and break-in events can create sudden window failures that leave a home exposed to weather and security risks. Emergency window services provide same-day and next-day response, temporary boarding, glass unit removal and covering, and interim sealing to protect the interior until permanent repair or replacement can be safely scoped and completed. Available 24 hours. Call (720) 408-1840 for emergency response. See full Emergency Window Services details → Includes: what to do before we arrive, insurance documentation, temporary vs. permanent solutions, and response times across the Denver Metro.

Denver window cost

How much does window replacement cost in Denver?

Direct answer: In Denver, window repair runs about $100 to $600 per window, while window replacement runs about $450 to $1,200 per window installed. Replacement adds 20 to 30 years of lifespan and lowers bills with double-pane low-E glass, most window projects finish in 1 to 2 days.

Window repair Denver

$100 to $600 / window

Best for a foggy or failed seal, broken glass, or minor frame or sash damage. Same day to 1 day, adds a few years of lifespan.

Window replacement Denver

$450 to $1,200 / window installed

Best for single-pane or aging windows, widespread damage, drafts and high energy bills. 1 to 2 days, adds 20 to 30 years and lower bills.

When hail or storm damage is the cause, an approved insurance claim often covers most of the cost beyond your deductible. Hail damage that breaks glass, cracks frames, or compromises window components is typically covered under homeowners insurance. We document the full exterior so nothing covered gets left behind.
Your full exterior system

Windows in the context of your full exterior system

Direct answer: Windows do not fail in isolation. The roofing, siding, and gutter systems surrounding every window opening directly affect window performance and longevity, and storm events that damage windows almost always damage other exterior systems simultaneously.

Flashing and water management. Window flashing, the sheet metal and membrane system that directs water away from the rough opening, sits at the intersection of the window unit, the wall sheathing, and the exterior cladding. When siding is replaced without proper window flashing inspection and integration, new moisture infiltration pathways are created at the window perimeter. An exterior contractor who works across roofing, siding, and windows brings a complete picture to any moisture problem near a window opening.

Storm damage assessment. A hail event that breaks window glass will also leave impact evidence on roofing, siding, gutters, and soft metals across the same elevations. Insurance adjusters who assess only the window claim miss the full scope. A combined exterior assessment after any significant storm event, covering all systems in a single inspection, produces more complete documentation and a more accurately scoped claim. We routinely identify window damage during post-storm roofing and siding inspections that homeowners were not aware of.

Siding and window integration at replacement. When siding is replaced, the integration point between new siding, window casing, and flashing requires deliberate attention. Gaps, improper lapping, or missing sealant at this junction are the most common source of post-renovation moisture infiltration. We manage this integration as part of combined siding and window replacement scopes.

Choosing a window contractor

Why an exterior contractor for windows

Direct answer: The Denver window market includes window-only specialists, big-box retailers, national window brands with local franchises, and full exterior contractors like Precision Exteriors. The contractor type matters because windows and the surrounding systems are inseparable.

1

Windows and surrounding systems are inseparable

The most common cause of window performance failure that is not the window itself is improper flashing, deteriorated exterior casing, or moisture infiltration at the siding-to-window transition. A full exterior contractor assesses the complete system, wall assembly, flashing, casing, and the window unit together, and tells you whether the window or the surrounding system is the actual failure point.

2

Post-storm combined scope is standard

After a hail event, damaged windows, roofing, siding, and gutters on the same home need to be documented together for a single insurance claim. We document the complete exterior, windows alongside the roofing, siding, and gutter damage from the same event, producing a single comprehensive claim scope that captures the full extent of storm damage.

Window questions, answered: Precision Exteriors' FAQs

How do I know if my windows need repair or full replacement?
The clearest indicators for full replacement are failed IGU seals, visible as fogging, condensation, or a milky film between panes that does not clear, frame deterioration from rot, significant warping, or physical damage that prevents proper operation, and hail or debris impact that has broken glass or structurally damaged the frame. Repair is appropriate when the frame is sound and the failure is contained: a failed glass unit in a solid frame, hardware failure, or weatherstripping and flashing issues. A free inspection that evaluates both frame and glass unit condition is the reliable way to make this call.
Why do windows fog between the panes in Colorado?
Fogging between panes is caused by seal failure on the insulated glass unit. When the hermetic seal breaks, outside air, carrying moisture, enters the sealed space and condenses on interior glass surfaces when temperatures drop. Colorado's thermal cycling, high UV, and low humidity accelerate this process compared to more temperate climates. A failed IGU seal cannot be repaired, the glass unit requires replacement. If the frame is in good condition, IGU-only replacement is often the right path.
Does Colorado law require specific windows for replacement projects?
Yes. As of January 2026, HB 23-1161 requires ENERGY STAR certification for all replacement windows on residential structures three stories or lower in Colorado. For Denver Metro homeowners, this means the windows you install must meet Northern climate zone U-factor and SHGC thresholds. There are altitude-specific considerations around how this compliance works at 5,280 feet, we navigate those requirements on every replacement project.
Does insurance cover hail damage to windows?
Hail damage that breaks glass, cracks frames, or compromises window components so they no longer function correctly is typically covered in storm damage claims under homeowners insurance. The standard is functional damage, not purely cosmetic. Documentation with clear photographs before any temporary boarding is the most important first step. Window damage is frequently included in the same claim as roofing and siding damage from the same event.
What window features matter most in Denver's climate?
The most relevant factors for Front Range windows: Low-E glass coatings that balance solar heat gain control with passive solar benefit at altitude; U-factor of 0.30 or below for thermal performance in Colorado winters; frame material stability across wide thermal cycling ranges, fiberglass and composite frames outperform vinyl in extreme temperature cycling; altitude-rated IGU construction for long-term seal integrity at 5,280 feet; and ENERGY STAR certification for HB 23-1161 compliance.
How long do windows last in Colorado?
Quality vinyl-framed windows installed correctly in Colorado typically last 20 to 30 years. Fiberglass and composite framed units last 30 to 40 years or more. The most common failure mode is IGU seal failure, typically occurring at 15 to 25 years depending on glass quality, UV exposure, and thermal cycling frequency. South and west-facing windows typically fail first. Frame deterioration usually follows seal failure, and occurs later in quality installations.
How long does window replacement take in Denver?
Most window projects finish in 1 to 2 days, and free inspections are usually within the same week. Window repair is often same day to 1 day. New window installation that modifies a rough opening involves more structural scope and may take longer. We give you a clear timeline after the free inspection.
