Expert Ductwork Sealing in Greensboro, NC

Leaky ductwork is one of the most common and costly problems in Greensboro homes. When ducts develop gaps, loose connections, or deteriorated seals, conditioned air escapes before it reaches the rooms it is meant to serve. Clean Air's ductwork sealing service locates every leak in your system and seals it using professional-grade materials built to last. Greensboro's humid climate accelerates the breakdown of duct tape and older sealants, which is why we use mastic sealant and metal-backed tape rated for long-term performance. Sealed ducts keep conditioned air where it belongs, reduce the load on your HVAC system, and lower your monthly energy costs. Rooms that have always felt too warm or too cool often improve significantly after a proper sealing. If your energy bills have been climbing or your system runs constantly without reaching the set temperature, leaky ducts may be the cause. Call Clean Air to schedule a ductwork sealing assessment in Greensboro today.

Ductwork Sealing FAQ

Common questions about ductwork sealing in Greensboro, NC.

Rooms that never reach the right temperature, high energy bills, and a system that runs constantly are common signs. Clean Air can assess your duct system and identify where air is escaping.

We use mastic sealant and metal-backed tape rated for long-term performance. These materials hold up in Greensboro's humid climate far better than standard duct tape.

Yes, sealing leaks keeps conditioned air in the duct system instead of escaping into attics or crawlspaces. Most Greensboro homeowners see a noticeable reduction in energy costs after a proper sealing.

Yes, gaps in ductwork can pull in unconditioned air from attics or crawlspaces, which may carry dust, mold spores, or humidity. Sealing those gaps keeps that air out of your living spaces.

Professional sealing with mastic sealant can last many years when applied correctly. Greensboro's humidity makes material selection important, which is why we use products rated for long-term performance.

No, ductwork sealing is a non-invasive process that does not require you to vacate your home. Our technicians work within your duct system and clean up after the job is complete.

I highly recommend Rick and his team for any basement or crawl space job. They did a crawl space encapsulation for us with high quality work at a great price. They went above and beyond to make our house safer from mold and dust adding a dehumidifier. Our house now feels cleaner, less dust and the humidity at the proper level. Rick, Noah and Stephen were great to work with, solved problems, and were able to get the job done quickly. . This was one of the best investments we have done for our new Irving park home. I cannot recommend them enough.

Rick and Noah are the BEST! They answered all of my questions and were super knowledgeable. They made me feel super confident in my decision and I knew I had the right guys for the job. They worked efficiently professionally and were super kind. The communication was top-notch and the work was even better.

Noah and his team “under promised and overperformed” they totally cleaned out our crawlspace did some mold remediation, and completed the encapsulation as well as thoroughly cleaned the ductwork ,trunk lines, and all vents.End result was perfect. It’s always nice working with people that deliver more than expected. Very courteous, attention to detail are all the things that they delivered when they performed our crawlspace, remediation, encapsulation.

Rick, Noah and all the crew at Clean Air did an outstanding job on our house in Greensboro, NC. Called for a quote and Rick was out quickly and gave us an outstanding price on a full crawl space encapsulation and cleaning of the vents/returns. The employees were prompt, easy to talk to and answered all my questions. They did a thorough job removing the old insulation, soda blasting any mildew that had formed over the years and checking for any other potential problems. They have been out or have been in contact several times to check on any concerns, which there haven't been any. I couldn't have gone with a better company to address all of our crawl space concerns. Peace of mind has been priceless. Thank you again to the guys at Clear Air!
