Air Leak Inspection — Blower Door, Sealing & Verification

Find the drafts, stop the waste, lower the bills. We test your home with a blower door, track leaks using smoke and infrared, then seal the biggest offenders so comfort improves the same day.

What we check

• Attic bypasses: top plates, can lights, chases, attic hatch
• Perimeter leaks: rim joists, pipe/wire penetrations, exterior outlets
• Windows/doors: weatherstrips, thresholds, latch alignment
• Ductwork: leaks at plenums, boots, returns

Why it works

Seal first, then insulate. Reducing air leakage stabilizes temperatures, cuts noise, and shortens HVAC run time.

Our process

• On-site assessment: blower door baseline, IR scan, smoke tracing
• Plan after the visit: prioritized sealing list for accessible areas
• Sealing & tune-up: foam, sealants, gaskets, hatch weatherization; safe clearances at flues
• Verification: post-seal blower door reading and a photo report
