BOULDER EXTERIOR REMODELING BY COLORADO’S BACK-TO-BACK PRESIDENTS CLUB AWARD WINNER
Boulder is unlike any other market in Colorado. At 5,400 feet of elevation, nestled against the Flatirons and the wildland-urban interface, your home faces weather extremes that most exterior products simply aren’t designed for — Chinook winds gusting past 100 mph, relentless UV radiation, punishing spring hailstorms, and wildfire risk that moved from abstract concern to lived reality after the Marshall Fire. Your exterior isn’t cosmetic. It’s structural protection.
5280 Exteriors has been serving Boulder homeowners for over 20 years. We are one of only a handful of contractors in Colorado to earn James Hardie Elite Preferred status — and the only contractor in the state to win the James Hardie Presidents Club Award back-to-back in 2024 and 2025. That recognition isn’t a marketing badge — it reflects the highest standards for installation quality, customer satisfaction, and volume across the country.
WHY BOULDER HOMES DEMAND MORE FROM THEIR EXTERIOR
Most exterior products are tested to national averages. Boulder’s climate isn’t average. Here’s what your home is up against:
- Chinook winds: Boulder’s famous downslope winds regularly exceed 80 mph and have been recorded above 100 mph — enough to peel poorly installed siding, shatter single-pane windows, and compromise roofing systems
- UV radiation at elevation: Boulder receives significantly higher UV intensity than sea-level cities, accelerating paint fade, material degradation, and thermal expansion in low-quality products
- Spring hail: Boulder sits in Colorado’s primary hail corridor, with damaging storms increasingly common each season
- Wildfire interface: The Marshall Fire (December 2021) destroyed over 1,000 structures in Louisville and Superior — communities with similar exposure to Boulder foothills neighborhoods. Non-combustible exterior materials are no longer optional for fire-conscious homeowners
- Dramatic temperature swings: 50-degree swings in a single day create freeze-thaw stress cycles that crack and warp inferior siding materials over time
JAMES HARDIE SIDING INSTALLATION IN BOULDER
James Hardie fiber cement siding is the single best-performing exterior product for Boulder’s climate. The HZ10 formulation is engineered specifically for freeze-thaw conditions. It is non-combustible, impact-resistant, and impervious to the moisture cycling that destroys wood and vinyl siding within a decade at Front Range elevation.
Siding Products We Install in Boulder
- HardiePlank Lap Siding — the most popular profile in Boulder, available in smooth and wood-grain textures
- HardiePanel Vertical Siding — ideal for modern and contemporary Boulder architecture
- HardieShingle Siding — perfect for craftsman and traditional Boulder homes
- HardieTrim — coordinated trim boards for a finished, cohesive exterior
- ColorPlus Technology — factory-applied finish with a 15-year fade warranty, far outperforming field-painted alternatives at altitude
Popular Boulder Color Palettes
Boulder homeowners gravitate toward colors that complement the natural landscape — the green foothills, the warm sandstone of the Flatirons, and the clean mountain light. Our most-requested combinations:
- Iron Gray or Cobblestone with black windows and trim — modern mountain aesthetic
- Monterey Taupe or Night Gray with warm wood accents — contemporary foothills look
- Arctic White or Sailcloth with crisp black framing — clean contrast for North Boulder and Newlands homes
- Mountain Sage or Woodland Cream — earthy, naturalistic palettes for older Boulder neighborhoods
WINDOW REPLACEMENT IN BOULDER
Boulder homes often feature large windows designed to capture the Flatirons views and mountain light. Those same windows are also your home’s greatest source of energy loss. At 5,400 feet, proper glazing technology — argon gas fills, low-E coatings, and warm-edge spacers — makes a measurable difference in comfort and heating costs.
Window Products We Install
- Pella Impervia Fiberglass Windows — our top recommendation for Boulder; fiberglass expands and contracts at nearly the same rate as glass, eliminating the seal failures common in vinyl at altitude
- Pella Lifestyle Series — wood-interior windows for historic and craftsman Boulder homes
- Pella Reserve Series — premium wood windows for high-end Boulder remodels
- Anlin Windows — energy-efficient vinyl option with excellent performance at a lower price point
ROOFING IN BOULDER
Boulder’s hail exposure and wildfire risk make roofing decisions consequential. We install GAF roofing systems with Class A fire-rated assemblies and Class 4 impact-resistant shingles — the highest rating available for hail protection — which can qualify Boulder homeowners for insurance premium reductions.
DECKING & OUTDOOR LIVING IN BOULDER
Boulder homeowners invest in outdoor living. With over 300 days of sunshine annually and access to open space, a well-designed deck is one of the highest-ROI improvements in this market. We install TimberTech PVC composite decking — low maintenance, fade-resistant, and available in natural wood-look profiles that complement Boulder’s aesthetic. We can also spec aluminum framing for fire-resistant deck builds in WUI zones.

FREQUENTLY ASKED QUESTIONS ABOUT BOULDER EXTERIOR REMODELING
Is James Hardie siding non-combustible?
Yes. James Hardie fiber cement siding is made primarily from cement, sand, and cellulose fiber. It will not ignite when exposed to direct flame or radiant heat from a wildfire, making it one of the most important materials available for Boulder homeowners in the wildland-urban interface.
Does siding installation require a permit in Boulder?
Boulder County and the City of Boulder both require permits for full siding replacement. 5280 Exteriors handles all permitting as part of your project — you don’t need to manage it separately.
What is the best window for Boulder homes?
We recommend Pella Impervia fiberglass for most Boulder homeowners. Fiberglass is dimensionally stable — it doesn’t expand and contract with temperature swings the way vinyl does — which protects the insulating gas fill and extends the life of the seal. It also handles UV and altitude better than vinyl over time.
How long does a siding project take in Boulder?
A typical single-family siding replacement in Boulder takes 3–6 days of installation, depending on home size, profile, and scope. We schedule around Boulder’s weather windows to minimize exposure of your home during the process.
Do you serve Boulder foothills communities?
Yes — we regularly work in Boulder Heights, Four Mile Canyon, Sunshine Canyon, and other mountain communities west of Boulder. We’re familiar with WUI requirements, HOA guidelines, and the access logistics these projects involve.
