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.

Why DIY Duct Sealing Falls Short?
DIY duct sealing might save you money upfront, but it often misses hidden leaks and uses cheap materials. At DC Restoration Enterprise, our professional duct services catch every problem, thanks to our state-of-the-art tools and years of duct experience.
Count on our duct sealing to provide you with cleaner air, lower bills, and a longer-lasting HVAC system. We’ll get the job done right every time.

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.
