Duct Sealing Service in Mesquite, TX
Duct sealing means finding the gaps, holes, and poorly connected joints in your duct system and closing them so air stops escaping into unconditioned attic space. A leaking duct system can lose twenty to thirty percent of airflow before air ever reaches a register. Sealing is not a substitute for replacement when ducts are structurally failing, but for systems in decent shape, it's the most cost-effective fix for uneven cooling and high energy bills.

When to Call
When You Need Duct Sealing Service
- Your Mesquite electric bill spikes every summer even though the unit itself checks out fine.
- One side of your house stays five degrees warmer than the other regardless of what you set.
- You can feel air blowing in your attic near the air handler when the system runs.
- An energy audit flagged significant duct leakage in your attic return system.
How It Works
Our Process for Duct Sealing Service
- 1
Leak Location
We pressurize the duct system and use airflow and visual inspection to locate joints and connections that are losing air.
- 2
Joint Preparation
We clean dust and debris from leaking connections so mastic or metal tape can bond properly and hold long-term.
- 3
Sealing
We apply mastic sealant or UL-listed metal tape to every identified leak point, working from the air handler out to the registers.
- 4
Verification
We re-pressurize the system and confirm leakage is reduced, then run the system to check for improved airflow at problem registers.
Mesquite Context
Why this matters in Mesquite
Mesquite's extreme summer heat means attic temperatures can reach 140 degrees. Any air leaking out of your ducts up there is money your system spent conditioning air that never cooled a single room.
Straight Talk
About pricing & scope
Labor time depends on how many leak points exist and how accessible the duct runs are in your attic. Homes with buried ducts under heavy insulation take longer to inspect and seal than those with exposed runs.
