About Us

Denver’s Energy Efficiency Specialists

At AtticPro Insulation, we don’t just blow insulation into a space and call it a day. We look at your home through the lens of strict building science. The Denver Metro climate is brutal on a building envelope, forcing your heating and cooling systems to work double time as conditioned air bleeds right through your attic floor.

We founded AtticPro to bridge the gap between basic local contractors and advanced energy efficiency engineering. As BPI Certified Building Analysts, we diagnose the hidden structural flaws in your home’s envelope, deploy permanent thermal solutions, and instantly deduct your utility incentives straight from the invoice. No guesswork. No shortcuts. Just a high performance home.

Services

Premium Attic Services, End to End

Lower bills. Warmer winters. Cooler summers. One certified crew for everything your attic needs.

Attic and wall insulation installation

Attic & Wall Insulation

Stop Thermal Bleeding. We seal thermal bridges and blow premium, high density insulation to hit strict Colorado R60 standards. Keep your heat inside during freezing winters and lock out scorching summer attic temperatures.

Spray foam insulation application

Spray Foam Insulation

The Ultimate Airtight Thermal Barrier. Perfect for custom remodels, knee walls, and unvented roof decks. Our premium spray foam expands to eliminate the structural air leaks that standard insulation completely misses.

Blown in fiberglass and cellulose insulation

Blown-In Fiberglass & Cellulose

Maximum Thermal Defense at R60 Density. We use advanced, high volume pneumatic blowing systems to evenly distribute premium, fire retardant fiberglass or cellulose, eliminating gaps and instantly halting ice dam formation.

Rodent proofing for attics

Rodent Proofing

Evict Pests. Seal the Envelope. Rodents destroy R value and ruin indoor air quality. We don’t just trap them; we steel mesh drop points, sanitize fouled spaces, and structurally block attic entry vectors for good.

New construction insulation

New Construction & Remodel

Engineered Building Envelopes. We partner directly with Denver custom builders and homeowners to deliver high performance, code compliant insulation assets from the pre drywall phase onward.

Crawl space encapsulation

Crawl Space Encapsulation

Stop Freezing Floors & Foundation Moisture. We seal your crawl space with heavy duty vapor barriers and premium insulation to eliminate damp air, structural wood rot, and the upward stack effect that chills your main floors.

Attic air sealing

Attic Air Sealing

Plug the Hidden Energy Leaks First. Insulation without air sealing is just a wool sweater in a windstorm. We locate and seal hidden gaps around top plates, light fixtures, and plumbing stacks to trap conditioned air where it belongs.

Solar attic fan on a roof

Solar Attic Fans

Active Solar Heat Extraction. Drop your attic temperatures by up to 50°F without drawing a single watt from your electrical grid. Active ventilation protects your shingles from baking and lightens the load on your AC.

Old insulation removal

Insulation Removal

Safe, Clean Bio Hazard Extraction. We completely vacuum out contaminated, degraded, or fire damaged insulation using high powered external negative pressure systems, leaving your attic spotless, sanitized, and ready for a fresh start.

FAQ’s

Frequently Asked Questions

How do I know if my home needs new insulation?

If you notice massive utility bill spikes during Denver’s freezing winters or high altitude summers, uneven temperatures between your upstairs and downstairs rooms, or ice dams forming on your roof eaves, your attic is actively venting conditioned air. A quick diagnostic audit will show your exact current R value.

How much can I really save on my energy bill?

By sealing structural air leaks and upgrading your attic thermal defense to code compliant R60 standards, you stop your HVAC system from working double time. Most Front Range homeowners experience up to a 50% permanent reduction in heating and cooling costs, meaning the upgrade completely pays for itself.

How do the Xcel Energy rebates work?

AtticPro is an Xcel Energy registered contractor. We check which rebates your project qualifies for, file all the paperwork for you and deduct the incentive directly from your invoice. Qualified savings range from hundreds of dollars up to about $3,000.

How long does attic insulation installation take?

Most standard residential attic retrofits, including vacuuming out old materials, detailed structural air sealing, and blowing fresh premium R60 insulation, are completed in just 4 to 6 hours. Our crews deploy heavy duty containment barriers to ensure your living space stays pristine, leaving your home completely clean before they pack up.

What areas of the home do you insulate?

While we specialize in high efficiency attic insulation upgrades and comprehensive air sealing, our team engineers whole home thermal envelopes. This includes attic flats, vaulted knee walls, crawl space encapsulations, rim joists, and targeted wall insulation injections for existing structures.

What types of insulation do you install?

We utilize high performance, code compliant building materials tailored to the Colorado climate. This includes premium, fire retardant blown cellulose, high density stabilizers, and advanced expanding spray foam for precision air barrier execution.

Is there a warranty?

Yes. Installed insulation is covered by a limited lifetime warranty, and every project is backed by our 100% customer satisfaction guarantee.

Do you offer financing?

Yes, financing options are available, and rebates reduce your cost before financing is even applied. Ask about current plans during your free audit.
