Air Duct Sealing Service in Richardson, TX

Air duct sealing closes the gaps, loose joints, and deteriorated connections in your duct system that let conditioned air escape before it reaches your living spaces. In a typical home with leaky ducts, a meaningful percentage of your cooled or heated air never makes it out of the vents. Duct tape — the real kind homeowners use — fails within a few years in an attic environment. We use mastic sealant and metal-backed tape rated for the temperature swings your attic actually sees.

When to Call

When You Need Air Duct Sealing Service

  • Some rooms in your Richardson home are always stuffy regardless of how long the AC runs
  • Your utility bills are high and your equipment checks out fine, but something is clearly wrong
  • You can feel air blowing in your attic near duct joints when the system is running
  • Your home has original ductwork from the 1980s that's never been inspected or touched

How It Works

Our Process for Air Duct Sealing Service

  1. 1

    Duct Inspection

    We get into the attic and physically trace the duct runs, looking for disconnected sections, gaps at boots, and joints that have pulled apart.

  2. 2

    Leakage Assessment

    We note where leakage is happening and estimate how much conditioned air is being lost before starting any sealing work.

  3. 3

    Mastic Application and Taping

    We apply mastic sealant to all accessible joints and connections, then reinforce with foil-backed tape where the geometry requires it.

  4. 4

    Airflow Comparison

    We check supply airflow at registers after sealing to confirm improvement is measurable, not just theoretical.

Richardson Context

Why this matters in Richardson

Richardson attics routinely hit 140 degrees in summer, which degrades older duct connections faster than anywhere else in the house. Homes built before 1995 in neighborhoods like Berkner and Greenwood Hills often have duct systems that have never been sealed.

Straight Talk

About pricing & scope

Accessible joints in a simple duct layout take less time than a complex system with flex duct runs that have sagged or kinked. We seal what we can reach safely; duct replacement is a separate discussion if sections are collapsed.
