Duct Sealing Service in Corpus Christi, TX
Duct sealing means applying mastic compound or aerosol sealant to close the gaps and loose joints in your existing duct system. When ducts leak, your air conditioner pushes cooled air into the attic instead of into your living space, and your system runs longer to compensate. This is one of the more common reasons for high electric bills in otherwise well-maintained homes. Sealing is the right approach when the duct structure itself is still in good shape.

How It Works
Our Process for Duct Sealing Service
- 1
Leak Detection
We pressurize the duct system and identify where air is escaping, including joints, collars, and plenum connections.
- 2
Access Preparation
We clear access to problem areas in the attic or crawlspace and confirm insulation isn't masking additional leak points.
- 3
Mastic Application
Mastic sealant gets applied to every identified gap and joint, then reinforced with mesh tape where needed for durability.
- 4
Post-Seal Verification
We re-test system pressure after sealing to confirm leakage has dropped to an acceptable level before closing up.
Corpus Christi Context
Why this matters in Corpus Christi
In Corpus Christi, duct leakage also pulls unconditioned humid air back into the system on the return side, which drives up indoor humidity and makes rooms feel uncomfortable even at a reasonable temperature. Sealing both supply and return leaks matters here.
Straight Talk
About pricing & scope
Scope is driven by how many leak points exist and how accessible your duct system is. Aerosol sealing methods cost more than manual mastic work but reach leaks inside duct runs that can't be accessed physically.
