Where is the moisture coming from?

Water, bare soil and humid air need different fixes.

Water collects after rain

We check where water enters and where it can go. Drains and sump pumps collect and move water. If a pipe is leaking, it needs a plumbing repair.

The ground is exposed or the cover is damaged

Bare soil releases moisture into the air. A vapor barrier covers the ground. We check for missing cover, torn seams and open edges before recommending repair or replacement.

Surfaces stay damp without standing water

Humid air can leave moisture on cool surfaces. Sealed openings limit damp air coming in; a dehumidifier removes moisture from the air inside. These do a different job from a drain.

Why a crawl space can stay damp after earlier work

Many homeowners already have plastic on the ground or a portable dehumidifier. The next step is to examine how that setup is working with the rest of the space.

Ground cover, drainage and dehumidification each handle a different source of moisture. A working dehumidifier can still struggle with open vents or uncovered soil, while a barrier cannot carry away standing water. Checking how those parts work together helps us find the remaining problem.

We consider the existing installation before recommending more work. Photos of the water, notes about when it returns and an earlier inspection report can help us see why the dampness keeps coming back.

How we bring crawl space moisture under control

We plan the work around what is making your crawl space damp and what is already installed. You’ll know the order of the work, expected timing, and access needed before we start.

Start with water and access

We clear the areas that need work and address how collected water will leave the crawl space. A leak needs the appropriate repair before more material covers the area.

Treat affected wood before sealing the space

Existing mold needs treatment of its own. We explain any insulation removal and quote mold work separately from the moisture improvements.

Install the moisture controls your home needs

A barrier, sealed openings, and a properly drained dehumidifier each have a different job. We explain which combination fits your home and how it works with useful existing equipment.

 Trustindex verifies that the original source of the review is Google. 2026 - Moved to a new home and, Clean Air LLC, I cannot recommend enough! We had work done to our home in Greensboro back in April, and Rick was more than accommodating. He went out of his way to answer many of my questions and always responded promptly and with clear guidance on next steps. He worked with us to get a fair price within our budget that also addressed the immediate concerns of the home. We were able to have him not only clean out our vents but help us with a partial encapsulation and dehumidifier setup in the crawlspace. His team is efficient, thorough, and friendly. If you ever have any type of vent or crawlspace need, you would be hard-pressed to find a more knowledgeable, honest, and transparent company than Rick and his crew at Clean Air LLC. Absolutely would recommend! - Derek & Kelly

2021 - Had some very dirty ducts and vents on a new home purchase. Called up Clean Air and they were able to get the ducts looking like new. They are very responsive, professional and courteous. They first came to the house to do an inspection of the ducts and vents which was a nice touch. They took pictures and explained their process. When they came to do the work they were very thorough and courteous. Highly recommend this company.

 Trustindex verifies that the original source of the review is Google. The crew were friendly and courteous. They were very open and flexible about my need to “herd” my cats and dog from one room to another while their work progressed.

They helped me understand what action might be required based on the conditions of my ductwork for my 20 year old house.

 Trustindex verifies that the original source of the review is Google. We had Mr Rick Watson and his company Clean Air encapsulate our crawl space and are very happy with his work.  During the work Noah and the crew kept us informed and were able to deal with an unusual problem they found in our crawl space.  Both he and his crew were very helpful in accommodating a couple of requests we made and always cleaned up the area at the end of each day.  They were a pleasure to work with and I do recommend this company.

 Trustindex verifies that the original source of the review is Google. 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.

How do I know which service I need?

You do not have to choose the equipment first. Tell us where the dampness appears and what is already installed. We check water entry, ground cover, and humidity, then explain which work addresses each problem.

What will the work cost?

The cause of the dampness, preparation, access, and equipment affect the price. Our good, better, and best written options for crawl space encapsulation explain the work and cost, including useful equipment you already own. Ask about current financing options.

Does drying the air remove mold from the wood?

No. Moisture control addresses the conditions that allow growth. Mold already on the wood needs treatment of its own. We show any crawl space mold-removal work separately in the estimate.

Can you check work that has already been done?

Yes. Share previous estimates, inspection findings, and photos of recurring water if you have them. We look at how the barrier, drainage, and dehumidifier work together before recommending more work.

How long does a project take?

Combined crawl space and mold projects typically take four to five working days. Smaller jobs may take less. We confirm the order of work, timing, access, and arrangements for staying home before booking.
