Problems We Fix with Our Duct Sealing

Leaky ducts drive up your bills and leave rooms too hot or too cold. They can also shorten your HVAC system’s lifespan. Our duct sealing addresses those issues along with the following:

HVAC Wear and Tear

Sealing reduces system strain, helping your furnace and AC last longer with fewer breakdowns.

Dust and Debris

Sealing keeps pollutants and debris from being pulled into the ducts and circulated through your building.

Uneven Temperature

Properly sealed ducts improve airflow, helping maintain consistent temperatures across your property.

Energy Loss

Sealing prevents conditioned air from escaping into walls, attics, or crawl spaces, and secures even airflow.

High Utility Bills

When your system works harder to compensate for leaks, you pay more. Duct sealing fixes that problem.

How We Seal Your Ducts

Every property is different, so we start with a full inspection to find hidden leaks and weak spots. We then seal them using proven techniques that hold up over time.

  • Air Leak Testing: We pressurize the system and use sensors or smoke testing to pinpoint exact leak locations.
  • Hand Sealing with Tape: For exposed ducts, we use professional-grade mastic or aluminum tape to seal visible joints and seams.
  • Internal Duct Sealing: For hard-to-reach areas, we may apply an aerosol-based sealant inside the duct system to plug small leaks from within.
  • Final Test and Airflow Check: After sealing, we run a follow-up test to verify improvements in system efficiency and airflow.

Frequently Asked Questions

How do I know if my ducts are leaking?
You might notice high energy bills, weak airflow, dusty air, or rooms that stay too hot or cold. A pressure test confirms the problem.
Is duct tape enough to seal my ducts?
No. Standard duct tape breaks down over time. We use mastic sealant or foil-backed tape built for HVAC systems.
How long does duct sealing take?
Most projects take a few hours, depending on access and system size. You’ll get a clear estimate before we begin.
Does duct sealing improve air conditioning, too?
Yes. Sealing improves both heating and cooling performance by helping air reach every vent with less loss.
Is duct sealing messy?
No. The process is clean and contained, and doesn’t involve demolition. We leave the area as we found it.
