Duct Sealing Service in Tallahassee, FL
Duct sealing means locating the joints, connections, and gaps in your duct system where conditioned air is escaping before it reaches your living space. In many homes, 20 to 30 percent of cooled air leaks into attics or crawl spaces and never cools a single room. We use mastic sealant or foil tape at leaking joints — not the cloth duct tape that dries out and fails. This service directly cuts your utility bill and reduces humidity problems inside the house.

When to Call
When You Need Duct Sealing Service
- Some rooms never cool properly even after the system runs for hours

- You can feel air blowing from duct joints in the attic when the system runs
How It Works
Our Process for Duct Sealing Service
- 1
Duct Leakage Assessment
We inspect accessible duct runs in the attic and air handler connections to identify where leakage is happening and how severe it is.
- 2
Leak Location
We run the system and feel or measure airflow at duct joints, plenums, and flex connections to find the worst leaking points.
- 3
Sealing
We apply mastic sealant at rigid connections and use foil-backed tape at flex duct joints — materials that hold up in hot attics long-term.
- 4
Airflow Verification
We check register airflow in the rooms that were problematic and confirm delivery improved before calling the job done.
Tallahassee Context
Why this matters in Tallahassee
Tallahassee attics regularly reach 140 degrees in summer. Duct systems up there expand and contract daily, which eventually pulls joints apart even on systems that were sealed at installation.
Straight Talk
About pricing & scope
Cost depends on how many leaking connections exist and whether ductwork is accessible or buried under attic insulation. Systems with flex duct that has pulled apart at multiple connections take longer to seal properly than rigid metal systems.
