Air Sealing Services in Denver
Eco-Friendly, High-Performance Insulation That Fills Every Gap
Adding insulation on top of air leaks is like wearing a sweater with the windows open. Recessed lights, top plates, plumbing chases, the attic hatch, the chimney chase — every one of them lets heated air escape into the attic and pulls cold air in at the floor. PIKA seals those bypasses first, with foam, caulk and rigid blocking, then insulates. It's why our attic jobs actually change the way a house feels — and why they qualify for utility rebates that require a measured reduction in air leakage. Every job starts with a free in-home evaluation — we walk the house with thermal-imaging readers, show you where heat is leaving, and give you a written quote. No cost, no obligation.
Signs you need air sealing
- Ice dams along the roof edge every winter.
- Upstairs rooms hot in summer, cold in winter, no matter the thermostat.
- Drafts at the floor near exterior walls or the attic hatch.
- Dust streaks on insulation around can lights and top plates.
- A recent insulation top-up that did not change how the house feels.
Attic Insulation – Your First Line of Defense Against Energy Loss
Your attic is responsible for the majority of your home's heat loss. We install high-performance attic insulation that:
Improves your R-value to meet or exceed Denver climate recommendations
- Prevents warm air from escaping during winter months
- Keeps your home cooler in the summer
- Lowers heating and cooling bills significantly
A properly insulated attic can cut your energy use by up to 20% annually—and we make sure it’s done right the first time.
Where We Install Air Sealing
Attic floor
Seal top plates, can lights with fire-rated covers, plumbing and wiring penetrations, and chimney chases. We also address knee-wall transitions and the attic hatch to reduce drafts and unwanted heat loss.
Rim joist and crawl space
Apply spray foam around rim joists and sill plates to block drafts and unwanted air movement. This approach helps reduce cold floors in Columbine, Ken Caryl, and Littleton split-level homes.
Windows, doors and outlets
Seal gaps around windows, exterior doors, and electrical outlets to reduce drafts throughout the home. These low-cost improvements work well as part of a whole-home air-sealing package.
Garage-to-house wall and ceiling
Seal the shared wall and ceiling to limit air movement between the garage and living areas. This helps keep garage air and vehicle fumes away from bedrooms and other occupied spaces above.
Ductwork in unconditioned space
Apply mastic sealant to accessible duct joints in attics and crawl spaces to reduce air leakage. Sealing these connections helps limit energy waste and keeps conditioned air moving toward the rooms that need it.
Materials and How We Choose
We’re not just installers—we’re local insulation experts focused on quality, comfort, and energy performance. With PIKA Insulation, you get:
Diagnostic and assessment
We use thermal imaging during the free evaluation to identify heat loss and locate problem areas. When required for a rebate, we also perform a blower-door test to measure air leakage.
Materials and installation
We use one- and two-part spray foam, fire-rated sealants, rigid blocking, and weatherstripping. Our crew selects the appropriate materials for each area and installs them as part of the contracted service.
Post-work verification
We use a thermal scan or blower-door measurement after the work to check the results. This helps you compare conditions before and after the improvements and see where air leakage or heat loss has been reduced.
How a PIKA Job Works
Free In-Home Evaluation
We use thermal-imaging readers to identify heat loss throughout your home. You see exactly where insulation is underperforming instead of relying on guesswork.
Clear, Written Estimate
Receive a written quote during the same visit, with recommended work clearly outlined. We also flag potentially rebate-eligible items to help you plan costs.
Professional Installation Crew
Our own trained crew completes the installation without outside subcontractors. Most projects are finished in one day, depending on the home's size and scope.
Final Walkthrough and Testing
We clean the work area, walk you through the completed installation, and explain the results. When required for rebates, we also arrange post-work testing.
Serving Denver and The Metro
Based in Denver, we serve homeowners throughout the metro area, including Lakewood, Aurora, Littleton, Highlands Ranch, Westminster, Thornton, Parker, and Broomfield, along with the surrounding neighborhoods. Our crew provides the same professional insulation services and free in-home evaluations across our service area, helping homeowners identify heat loss, improve comfort, and reduce wasted energy. Wherever you're located in the metro, you can expect the same straightforward recommendations and reliable installation process.
Frequently Asked Questions
How much does attic air sealing cost in the Denver area?
As a stand-alone service, most attics run $600–$1,800 depending on size and the number of penetrations; bundled with an attic insulation top-up it's less. Exact pricing after the free evaluation.
Is air sealing worth it if I'm already adding insulation?
It's the part that makes the insulation work. Loose-fill insulation slows heat, but it doesn't stop air — a sealed attic floor is what stops the drafts and the ice dams.
Does air sealing qualify for the Xcel Energy rebate?
Xcel's insulation rebate requires a measured reduction in air leakage, so air sealing is part of every rebate job we do.
Can a house be too tight?
Only if nobody checks. We test combustion appliances (CAZ test) and recommend ventilation when a home gets tight enough to need it.
