Advanced air sealing that stops drafts, lowers bills, and improves your air quality
Our building scientists use blower-door testing and infrared imaging to find every gap, crack, and unsealed seam in your home — then seal them systematically from the attic floor to the basement sill plate. When recommended through a Home Energy Solutions audit, Energize CT rebates cover 75-100% of the cost for eligible Connecticut families.
Finding and sealing every gap in your home's envelope
Air sealing means closing every gap, crack, and unsealed seam that lets conditioned air escape or outdoor air in. Our building scientists pressurize your home with a blower-door fan and use infrared imaging to pinpoint the exact source of every leak.
Then we seal them systematically — attic floor to basement sill plate. When recommended through a Home Energy Solutions audit, Energize CT rebates can cover 75-100% of the cost for eligible Connecticut families.

How it works
From the first test to the final seal: how we do it
DIAGNOSTIC
We find every leak with diagnostic equipment
- Blower-door fan creates measurable pressure difference to reveal air movement
- Infrared imaging pinpoints leaks at rim joists, attic penetrations, and recessed lighting
- Complete leakage map of your home's envelope guides every sealing decision
SEALING WORK
We seal systematically, area by area
- Attic: urethane foam and caulk at penetrations, plus insulation reinforcement
- Basement: spray foam at sill plates and around plumbing, wiring, and cracks
- Living spaces and ducts: foam gaps, caulk frames, weatherstrip, and seal duct leakage
What air sealing does for your home
Sealed gaps at the rim joists, basement sill plate, attic floor, ducts, windows, and doors keep conditioned air inside and stop unwanted outdoor air from entering. Rooms that were always drafty become consistently comfortable.
Sealing the basement blocks the intrusion of harmful air associated with dampness, heating fuel, and furnace combustion from being drawn up into your living spaces. You get the immediate benefits of improved air quality and reduced humidity.
By sealing off gaps and crevices you reduce the energy needed to heat and cool your home, which leads to lower energy bills and a more sustainable living environment. The efficiency gains are immediate and long-term.
