Expert Crawlspace Moisture Control in Greensboro, NC

Crawlspace moisture control is one of the most practical steps a Lewisville homeowner can take to protect their home. The clay-rich soil common across this area holds water and releases it slowly, pushing moisture vapor upward into the crawlspace year-round. Heavy rain seasons add to that pressure, and warm outdoor air entering through unsealed vents condenses on wood joists, metal pipes, and insulation below your floors. At Clean Air, we seal the crawlspace from the ground up. The process covers vapor barrier installation across the floor and foundation walls, vent sealing, and dehumidification to keep humidity at a stable level. We inspect first, identify every moisture entry point, and build a solution around your specific space. The goal is a dry, sealed crawlspace that stops damage at the source and keeps the air in your living areas cleaner. If you are seeing musty odors, soft floors, or condensation under your home, contact Clean Air to schedule an inspection.

Crawlspace Moisture Control FAQ

Common questions about crawlspace moisture control in Greensboro, NC.

Musty smells, soft or uneven floors, and visible condensation under your home are common signs. Lewisville's clay soil and humid summers make these problems more likely in homes with unsealed crawlspaces.

No, encapsulation is a full sealed system that covers the ground, walls, vents, and air moisture control. A vapor barrier alone only covers the floor and leaves other entry points open.

Yes, sealing the crawlspace cuts off the damp conditions that cause musty odors to form. Once moisture is controlled, those odors stop moving up through your floors and into your living space.

Yes, a damp crawlspace forces your HVAC system to work harder to condition humid air. Sealing and dehumidifying the space helps your system run more efficiently.

A dehumidifier installed as part of the system should be checked periodically to confirm it is draining and running correctly. Clean Air can walk Lewisville homeowners through what to monitor after the work is done.

Professional installation is strongly recommended because a poorly sealed crawlspace can trap moisture and cause more damage than it prevents. Clean Air serves Lewisville homeowners with inspections and full encapsulation systems.

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!
