Hidden gaps around attic penetrations, top-plates, recessed lights, and rim joists can leak enough conditioned air to fill a hot-air balloon every day. Our targeted air-sealing service plugs those leaks so your HVAC system finally gets a break—cutting heating-and-cooling costs by an average 15 % and delivering quieter, cozier rooms year-round.
Why Air Sealing Matters
| Benefit | What It Means for You |
| Lower Energy Bills | EPA modeling shows up to 15 % HVAC savings after leaks are sealed. |
| Consistent Comfort | No more hot ceilings, cold floors, or mystery drafts. |
| Healthier Indoor Air | Tight gaps keep out pollen, dust, and humidity that fuel allergies and mold. |
| Quieter Home | A tighter envelope muffles traffic, wind, and neighborhood noise. |
| Building Durability | Reducing moist air infiltration protects framing from rot and rust. |
What Our Air Sealing Service Includes
- Blower-Door Diagnosis – Pinpoints the exact cubic-feet-per-minute (CFM) leakage.
- Thermal & Smoke-Pencil Scan – Reveals hidden cracks around recessed cans, chases, and knee walls.
- Targeted Sealing – Crews apply fire-rated caulk, spray foam, and weather-stripping to attics, crawl-spaces, and exterior penetrations.
- Combustion-Safety Check – Ensures water heaters and furnaces still draft safely after tightening the envelope.
- Verification Test-Out – A second blower-door run proves the leakage reduction and qualifies your utility rebate on the spot.

Frequently Asked Questions
Will air sealing make my house “too tight”?
No. We follow BPI guidelines, finishing with a combustion-safety test and leaving controlled ventilation that meets ASHRAE 62.2 standards.
Do I need additional insulation?
Most homes benefit from pairing air sealing with blown-in cellulose to hit R-38 in the attic; we’ll price both options so you can decide.
How long until I break even?
Typical payback is 1 – 3 years, faster if you pair air sealing with utility rebates.
Will I feel a difference right away?
Yes—rooms reach setpoint faster and stay there longer because drafts are gone.
Can I stay home during the work?
Absolutely. We isolate work zones and run HEPA vacuums to keep dust to a minimum.
