Duct Sealing Service in Hartford, CT
Duct sealing is the process of locating gaps, disconnected joints, and holes in your supply and return duct system and closing them with mastic or metal tape. Leaking ducts dump conditioned air into attics, basements, and wall cavities instead of into living spaces. Hartford homes with leaky ducts often have rooms that won't cool or heat properly no matter how well the equipment runs. Sealing the duct system is often what makes the rest of the HVAC system finally work as designed.

When to Call
When You Need Duct Sealing Service

How It Works
Our Process for Duct Sealing Service
- 1
Pressure Testing
We use a duct blower to pressurize the system and measure how much air is escaping before we start any sealing.
- 2
Leak Location
We trace the pressurized system and identify where leaks are — disconnected joints, loose collars, and gaps at registers are common spots.
- 3
Mastic and Tape Application
We apply UL-listed mastic sealant at joints and use foil tape on seams. We don't use standard duct tape, which fails within a few years.
- 4
Retest and Verify
We run the pressure test again after sealing to confirm leakage is reduced and document the before-and-after numbers for you.
Hartford Context
Why this matters in Hartford
Hartford's seasonal temperature swings mean ducts in unconditioned attics and basements deal with extreme hot and cold cycles that loosen joints over time. Many older Hartford homes have original duct systems with connections that were never properly sealed to begin with.
Straight Talk
About pricing & scope
Scope depends on how many leaks exist, where they're located, and how accessible the duct runs are. Ducts buried in finished ceilings or walls are harder to reach and may require more time or creative access solutions.
