Mold Remediation in Maryville, TN
Knoxville Superior Mold Remediation handles mold remediation in Maryville, TN the way we'd want it done under our own house. We take mold out of crawl spaces, attics, basements, bathrooms and the backs of walls, then treat the wood and clean the air so it stays gone. Find the water first. That's the rule we work by, because mold is almost always the receipt for a leak, a clogged gutter or damp air that nobody dealt with.
We're a family crew. Four of us, with more than 30 years in the trade, and the owner still goes under the house himself. We do about 150 mold jobs a year, most of them under the house. Maryville is a short run down Alcoa Highway, so we're in Blount County most weeks and can often come out the next day. Most Maryville calls end up being crawl space mold removal, and the damp ones get a crawl space encapsulation quote too. Next door in Alcoa, the old mill houses keep us just as busy.
Containment on every job

Maryville Homes and Where the Mold Hides
Maryville was incorporated in 1795 and had 31,907 people at the 2020 census, so the housing runs the whole range. We read a Maryville house by its decade before we look at a stain, because each era grows mold in its own favorite spot.
Older Homes Near Downtown and the College
Near Broadway and the college, a lot of houses sit on short crawl spaces with the old foundation vents still open. In August that warm, wet air rolls in, hits the cooler floor joists and turns to water. A damp crawl space is a garden somebody waters every night. Of course things grow. The musty odor in the hallway tells you before anything else does.
1960s and 1970s Ranches on Crawl Spaces
Brick ranches over dirt crawl spaces are most of what we see in Maryville's older subdivisions. Honestly, the original vapor barrier is usually shredded or gone. We find mold on the floor joists and the sill plate. Soggy fiberglass insulation sags between the boards. We text you photos from under the house so you see what we see.
Newer Homes With Basements on the Slopes
Built into a hill, a basement has one wall holding back the slope, and the slope sends its water right at it. In finished basements, mold hides behind drywall and under the carpet pad for months. We've seen plenty that nobody found until a buyer's inspector did.
Creeks, Hills and Blount County Rain
Maryville sits in the foothills of the Smokies with Chilhowee Mountain off to the south, and the water has to go somewhere. Pistol Creek cuts through town. The Little River runs along the east side. Lots near either one stay soggy for days after a storm, and this area gets just under 52 inches of rain a year.
Average relative humidity in the Knoxville area is about 71.5%, and it reaches 76% in August. The EPA recommends keeping indoor humidity below 60%. That gap is why so many crawl spaces in Maryville grow mold even without a leak.

What to Expect on a Maryville Mold Job
Same order every time, whether it's one closet off a bathroom or 1,800 square feet of crawl space.
- Inspection: we find the moldy area and the water source, and you get a written quote.
- Containment: plastic sheeting seals the work area and a HEPA air scrubber cleans the air.
- Removal: moldy drywall, insulation and debris come out and are bagged.
- Cleaning: wood and hard surfaces are cleaned and treated with EPA-registered products.
- Final check: a post-remediation evaluation confirms the area is clean and dry.
Here's the honest version: we won't start the cleanup until the leak is fixed or on the schedule. Containment is painting with the tape on, ten minutes of setup that saves the rest of the house, but none of it matters if the water keeps coming.
Mold Removal Services We Offer in Maryville
These are the jobs Maryville homeowners call us about most, roughly in order.
Crawl Space Mold Removal
Plastic containment goes up first. Then the moldy insulation and junk come out, and we clean the floor joists and subfloor. RMR-86 goes on stained wood, RMR-141 on anything washable. In our experience a Maryville crawl space takes one to three days, depending on how big it is and how low you have to crawl.
Basement Mold Removal
Moldy drywall and carpet pad come out. The block gets cleaned while a HEPA air scrubber runs the whole time. If water is seeping through the wall, we can add an interior French drain and a sump pump so the basement stays dry for good.
Attic Mold Removal
Attic mold shows up as dark spots on the roof sheathing, usually near the eaves or right around a bathroom exhaust fan that dumps its steam into the attic instead of outside. We clean and treat the boards and pull the wet insulation. Then we show you the vent fix. Simple.
Black Mold Removal
Black mold is a common name for dark mold. On wet drywall it's often Stachybotrys chartarum. Color alone doesn't tell you the species. We remove it the same careful way: containment first, then the moldy drywall comes out. Cleaning and a post-remediation evaluation finish it.
Crawl Space Encapsulation
Encapsulation turns the crawl space into a sealed, dry room. That means a heavy liner over the dirt and up the walls, closed foundation vents and a crawl space dehumidifier. It's a cooler with the lid shut. Ours carries a transferable lifetime guarantee, which helps when you sell.
Mold Inspection and Testing
If you smell mold but can't find it, we check with a moisture meter and thermal imaging, and we can take air samples for a lab. The inspection is free when it leads to a quote for work.
Mold Remediation in Maryville: FAQ
Do you charge to look at mold in a Maryville home?
No. The mold inspection is free, and you get a written quote before any work starts. We look at the mold, hunt down the water with a moisture meter and tell you straight whether it's a job for us or a weekend job for you. Lab air samples cost extra, and honestly most homes don't need them.
How long does mold remediation take in Maryville?
Most Maryville jobs take one to three days on site. A small bathroom or closet area can be done in a day. A full crawl space with insulation removal usually takes two to three days, and adding encapsulation adds about a day. We can often start within a few days of the inspection.
Why does my crawl space smell musty in the summer?
Warm, humid summer air comes in through the foundation vents and cools down under the house. Cool air can't hold as much water. So it drops it as condensation on the joists, pipes and ductwork. The wood stays damp. Mold follows. August under a house is its own weather.
Will homeowners insurance pay for mold removal?
Sometimes. Most policies cover mold only when it comes from a sudden covered event, like a burst pipe, and not from long-term humidity or a slow leak. The adjuster decides. We can give you photos, moisture readings and a written scope to send with your claim.
Can I clean a small patch of mold myself?
Yes, if it's small. The EPA says patches under about 10 square feet, roughly 3 feet by 3 feet, on hard surfaces are usually a do-it-yourself job. Wear gloves and an N-95 respirator, use soap and water, and dry the spot fast. Bigger areas or moldy drywall need a pro.
Do you work in other parts of Blount County?
Yes. Besides Maryville we work in Alcoa, Louisville, Friendsville, Walland and Townsend, and across Blount County. Trip time is part of the quote, so homes farther toward the mountains may cost a little more. Tell us your road when you call and we'll say how soon we can come.
