Duct Sealing Service in Boca Raton, FL
Duct sealing closes the gaps, loose connections, and failed mastic at duct joints so the air your system conditions actually reaches your rooms. It is not a replacement — it is a targeted repair for ducts that are structurally sound but leaking at seams and connections. A typical unsealed duct system loses 20 to 30 percent of conditioned air into the attic. That lost air is money your equipment already spent cooling that you never felt.

When to Call
When You Need Duct Sealing Service

- A blower door test flagged significant duct leakage during a home sale inspection
- Your air handler runs constantly but humidity inside stays high even in mild weather
How It Works
Our Process for Duct Sealing Service
- 1
Leakage Diagnosis
We pressurize the duct system and use airflow measurements to identify how much is escaping and roughly where.
- 2
Access and Preparation
We locate every accessible joint in the attic and air handler closet and clean surfaces so sealant adheres properly.
- 3
Mastic Application
We apply duct mastic by hand at every joint and seam — mastic outlasts duct tape by decades in this heat.
- 4
Post-Seal Verification
We re-test duct leakage after sealing so you have a before-and-after number, not just our word for it.
Boca Raton Context
Why this matters in Boca Raton
In Boca Raton, leaky ducts do more than waste cooling — they pull humid attic air into your system, forcing your AC to fight moisture it was never meant to handle. That extra load shortens equipment life in a climate where systems already run nine months a year.
Straight Talk
About pricing & scope
Price is driven by how many leakage points exist and how accessible your attic runs are. Homes with returns in tight closets or very low attic clearance take longer to seal correctly.
