INDOOR AIR QUALITY

Your home's air starts beneath the floor

Air rises from the crawl space into the house above it. When that space is damp or has mold, that air carries moisture, odors and spores into your ducts and the rooms you live in.

That's why we look at both. Clean ducts stay cleaner when the crawl space beneath them stays dry.

Up to 50%

of the air in your home can come up from the crawl space.

1

It starts in the crawl space

Damp soil, open vents and mold add moisture and spores to the air.

2

It rises into the house

Air moves up through gaps in the floor and into ductwork that runs beneath the home.

3

It reaches every room

Your heating and cooling system circulates it through the house.

The sealed barrier keeps soil moisture out

Crawl space encapsulation for a drier and healthier home

Crawl space encapsulation covers the soil with a sealed moisture barrier and closes openings that let humid outdoor air in. A dehumidifier can help control the remaining humidity.

The right system depends on how moisture enters your crawl space. Collected water may need drainage, and any existing barrier or dehumidifier needs to be checked before new work is planned.

Addressing mold beneath your home

We treat crawl-space mold separately. For home sales, share the report and closing date.

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.

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.

Steve and Zach were very professional and did an excellent job of cleaning duct work. They also taped around duct to help prevent insects, odors snd other small creatures from getting back in the ducts.

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.

Questions about our services

Still have questions? Give us a call at 336-707-0498. We’re happy to answer them.

How do I know which service I need?

Start with what you’ve noticed and where it happens. We’ll discuss the problem and arrange a closer look when needed. For an indoor mold concern, we can also explain what air testing would tell you and what it costs.

How long does the work take?

Residential air duct cleaning typically takes three to five hours. A typical crawl space project that includes mold remediation takes about four to five working days. Your home’s size, access and the scope of work affect the schedule. We will discuss the expected duration for your project.

Can I stay in my home while you work?

Homeowners can usually stay home during duct cleaning and crawl space work. More severe mold conditions can require different arrangements. We will discuss any precautions and whether you need to leave before the work begins.

Does encapsulation include mold remediation?

Mold treatment is listed and priced separately. Encapsulation helps keep the space drier, but growth already on the wood still needs to be treated. Your estimate will show both jobs when your home needs them.

What does mold testing cost?

Mold testing is a paid service that includes one indoor sample, one outdoor comparison sample, and laboratory analysis. Additional rooms or a different testing scope may change the price. We explain the full cost before proceeding.

How much will my crawl space project cost?

The price depends on the size and condition of your crawl space and the work it needs. We provide a free estimate and three written options for encapsulation. Mold remediation is listed separately, so you can compare what each price includes. Financing is available. Ask us about the current options when we prepare your estimate.
