Air Duct Sealing Service in Plano, TX
Duct leakage is one of the most common hidden reasons a home stays uncomfortable despite a working AC system. When supply or return ducts leak into unconditioned attic space, you're paying to cool or heat air that never enters your living areas. Sealing those leaks with mastic compound or foil tape — done correctly — can meaningfully improve comfort and reduce runtime. Most Plano homes built before 2005 have never had their duct joints sealed, and many lose twenty to thirty percent of airflow before it reaches the register.

When to Call
When You Need Air Duct Sealing Service
- One or two rooms are always hotter than the rest of the house despite open vents

- Rooms over the garage or at the end of long duct runs never reach the set temperature
How It Works
Our Process for Air Duct Sealing Service
- 1
Duct Leakage Assessment
We inspect accessible duct joints in the attic and mechanical room, looking for disconnected sections, gaps, and deteriorated tape.
- 2
Pressure Testing if Needed
For homes with significant comfort complaints, we can perform a duct blaster test to quantify leakage before and after sealing.
- 3
Mastic Sealing Application
We apply mastic compound to all identified leaky joints — it outlasts tape and won't shrink or peel over time the way older materials do.
- 4
Airflow Confirmation
We check static pressure and register airflow after sealing to confirm the fix actually improved delivery to problem areas.
Plano Context
Why this matters in Plano
Plano's extreme attic temperatures — often above 140 degrees in July — mean that every cubic foot of conditioned air leaking into that space is a direct loss you're paying for. Duct sealing pays off faster here than in milder climates.
Straight Talk
About pricing & scope
Scope depends on how much of your duct system is accessible and how many joints are leaking. Ductwork buried in walls or inaccessible soffits can't be sealed this way, and we'll tell you that upfront rather than promise results we can't deliver.
