Insulation Denver, CO | Level Up Insulation
Denver's BPI-certified insulation contractor — attic, crawl space, spray foam, and more. Xcel Energy rebates handled for you.
Level Up Insulation is Denver’s locally owned insulation contractor, serving the Front Range with every insulation service your home or commercial property needs. From attic blown-in and spray foam to crawl space encapsulation and insulation removal, we handle the full scope — Level up insulation is BPI-certified, and an Xcel Energy rebate verified partner. We provide a free on-site assessment/estimate that tells you exactly where your home is losing energy and what it will cost to fix it. Denver’s climate demands more from insulation than most markets, and Level Up is built specifically to deliver it.
Why Denver
Why Insulation in Denver Is Different From Every Other Market
Insulation in Denver homes has to perform in conditions that challenge every product on the market. At 5,280 feet, your home faces 40–50°F temperature swings in a single day, UV radiation 25% more intense than at sea level, and air so dry it accelerates thermal cycling through your framing, attic, and crawl space simultaneously. These aren’t conditions that standard insulation was designed to handle — and for most Denver homeowners, the result shows up in every utility bill, every winter with cold floors, and every summer with a house that just won’t stay cool.
The good news: Denver’s altitude and climate extremes are exactly why Xcel Energy’s rebate program is so generous for insulation upgrades. The energy savings from a properly insulated Denver home are larger and faster to realize than in virtually any other major U.S. market. Level Up’s free home insulation assessment/estimation gives Denver homeowners a precise picture of where they’re losing energy efficiency, before any commitment.
Why Denver Homeowners Choose Level Up Insulation
Level Up Insulation is a premiere Denver BPI-certified, Xcel Energy-partnered insulation contractor — two credentials that matter more in this market than anywhere else. We understand how Denver homes lose energy, how the Front Range climate affects different insulation materials, and how to design a solution that actually performs at altitude. Xcel Energy partnership means we’re qualified to assist with rebate documentation for every qualifying project, so Denver homeowners don’t navigate that process alone.
Beyond credentials, Level Up is locally owned and operated, which means we’re not a national franchise applying a template to Denver’s market. We work in these neighborhoods, we know the housing stock — the 1950s ranches in Lakewood, the Victorians in Capitol Hill, the new construction in Stapleton and Highlands Ranch — and we know what each type of Denver home needs to perform properly. Every project starts with a free assessment that gives you real numbers: your current R-value, what materials are needed, and how long the installation will take to complete. No pressure, no guesswork.

Insulation SERVICES
Denver Insulation Services from Level Up
Level Up Insulation provides every insulation service Denver homes and commercial properties need. Click any service below for full details, pricing information, and Denver-specific information:
The highest R-value insulation available — R-6.5 pzer inch for closed-cell. Eliminates air infiltration completely and handles Denver’s extreme temperature swings better than any traditional insulation. Best for attic rooflines, rim joists, crawl spaces, and basements.
Your attic is responsible for up to 35% of your home’s heat loss. Level Up brings Denver attics to R-49 with professional air sealing — always included, never an add-on. Xcel Energy rebates of $300–$800 for qualifying projects.
Denver’s most popular insulation upgrade — installed over existing material in a single day, covers every square inch regardless of obstructions. Cellulose blown-in is our top recommendation for the Front Range’s low-humidity climate.
Old, contaminated, or rodent-damaged insulation removed safely with commercial HEPA vacuum systems. Same-project replacement so your home is never left unprotected. Asbestos screening available for pre-1980 Denver homes.
Cold floors, pipe freeze risk, and moisture damage — Denver crawl space insulation solves all three. Full encapsulation with spray foam walls and 20-mil vapor barrier is our standard recommendation for Front Range homes.
Fiberglass and mineral wool batt insulation for Denver new construction and renovation — installed to the actual rated R-value, not close to it. R-21 exterior walls, R-15 interior, mineral wool for garages and party walls.
TAP insulation is the only EPA-registered insulation product — it insulates to R-3.6 per inch AND permanently controls 50+ crawling insect species. Ideal for Front Range homes in Denver’s urban-wildland interface.
Full-scale commercial insulation for Denver office buildings, warehouses, multi-family, and retail. Night and weekend scheduling available for occupied buildings.

Denver's Climate Makes Insulation More Important — and More Valuable
Insulation upgrades in Denver deliver a stronger return on investment than in most U.S. markets. — and the reason is the city’s exceptional climate. The combination of altitude, temperature swing, UV intensity, and freeze-thaw cycling that Denver homeowners experience creates insulation conditions that would be considered extreme anywhere else. Understanding what your Denver home is actually up against explains why proper insulation isn’t just a comfort upgrade — it’s a financial one.
At 5,280 feet, Denver’s atmosphere is 17% thinner than at sea level. That means every heating and cooling system in the city is working harder for the same output — and every gap in your insulation envelope is costing you more than it would in Denver, Texas. Denver’s average of 300 days of sunshine per year delivers intense UV radiation directly to your roof and attic, accelerating the thermal cycling that degrades traditional insulation over time. Denver’s Front Range temperature swings — regularly 40–50°F between overnight lows and afternoon highs — physically stress your home’s framing and insulation continuously, opening gaps that air-sealing and spray foam eliminate permanently.
This is why Colorado’s Energy Code requires R-49 in Denver attics when most southern states require R-30. It’s why Xcel Energy’s rebate program for Denver insulation upgrades is among the most generous utility rebate programs in the country. And it’s why Level Up’s approach — starting with a precise energy assessment, and documentation for every Xcel rebate — consistently delivers the kind of energy savings Denver homeowners feel immediately.

XCEL ENERGY REBATES
Xcel Energy Insulation Rebates for Denver Homeowners
Denver homeowners who upgrade their insulation through an Xcel Energy-approved contractor can receive $300–$800 in rebates for qualifying projects. Level Up is an Xcel Energy partner, which means we’ll provide you with the necessary information needed for you to complete the Xcel Energy rebate forms.
Xcel Energy’s Denver insulation rebate program covers attic insulation upgrades (including air sealing), blown-in insulation, and certain spray foam applications. Rebate amounts are determined by your R-value improvement and project scope — the bigger the gap between where your Denver home is and where it needs to be, the larger the rebate. Projects that bring attics from R-11 or R-19 (common in older Denver homes) up to R-49 qualify for the highest rebate tiers.
Insulation Services Across Every Denver Neighborhood
Level Up Insulation works across every Denver neighborhood — and the city’s diverse housing stock means we bring different expertise to each one. Denver’s older neighborhoods like Washington Park, Capitol Hill, Baker, and the Highlands are full of Victorian and craftsman-era homes that were built long before modern insulation standards existed. These homes are often sitting on original R-0 or R-11 insulation in attics with complex geometry, knee walls, and decades of modifications that make standard installation approaches inadequate.
Denver’s post-war neighborhoods — Park Hill, Wheat Ridge, Lakewood, Englewood, and Green Valley Ranch — are predominantly 1950s–1970s ranches and split-levels where original batt insulation has been settling and degrading for 40–60 years. These homes consistently benefit the most from blown-in attic upgrades with professional air sealing — and they’re exactly the projects Xcel Energy’s rebate program was designed for. Newer Denver communities including Stapleton, Sloan’s Lake redevelopment, and new construction in the southern suburbs require insulation that meets Colorado’s current Energy Code — R-49 attics, R-21 exterior walls — and Level Up installs to these specifications on every new construction project.

Frequently Asked Questions
Common questions about our Denver Insulation
The best insulation for Denver homes depends on the application. For attics, blown-in cellulose or spray foam are the top choices — cellulose blown-in is the most cost-effective path to R-49 for most Denver homes, while spray foam is best when HVAC equipment is in the attic or when maximum air sealing is the priority. For crawl spaces and basements, closed-cell spray foam is the standard recommendation in Denver’s climate. For new construction walls, R-21 fiberglass batts or mineral wool batts meet Colorado’s Energy Code requirements. Level Up’s free assessment estimate identifies the best approach for your specific Denver home.
Insulation costs in Denver vary by service, sq ft, and scope. Blown-in attic insulation is the most economical and common choice. Spray foam insulation is the more premium option, and will last much longer. Level Up provides detailed, itemized quotes for every project.
Level Up Insulation is an authorized Xcel Energy Rebate partner and provides our clients with all the necessary testing and documentation for them to submit to Xcel Energy to maximize their rebate.
The most common signs that a Denver home needs insulation are:
- Energy bills that have increased year over year without a rate change
- Cold floors in winter (especially over crawl spaces or garages)
- Rooms that are difficult to heat or cool, ice dams on your roof in winter
- Musty odors from the attic or crawl space
- Your home was built before 1990 that has never had an insulation upgrade.
Colorado’s current Energy Code requires R-49 for attics, R-20 to R-21 for 2×6 exterior walls, and R-25 minimum for crawl space floor joists in Denver’s climate zone. Most Denver homes built before 1990 are significantly below these targets — particularly attics, which commonly test at R-11 to R-22 in older Front Range homes. Level Up measures your current R-value during the free assessment and provides specific recommendations for your home.
Yes — Level Up Insulation is fully licensed, insured, and BPI-certified to operate in Colorado. BPI (Building Performance Institute) certification is the gold standard for residential energy efficiency work — Level Up carries full liability insurance and workers’ compensation coverage on every project.
Most residential insulation projects in Denver are completed in one day. A standard attic air sealing and blown-in insulation project takes 5-8 hours. A full attic removal and replacement takes one full day. Crawl space encapsulation typically runs 1–2 days depending on size and conditions. Spray foam projects vary by scope but most residential applications complete in one day. We confirm the specific timeline for your project during the free assessment, so you can plan accordingly. You can remain at home during the entire process.
Level Up Insulation serves the entire Denver metro and Front Range, including Aurora, Lakewood, Englewood, Centennial, Littleton, Highlands Ranch, Parker, Castle Rock, Thornton, Westminster, Arvada, Golden, Boulder, Broomfield, Fort Collins, Colorado Springs, and dozens of surrounding communities.
