Mold Remediation in Alcoa, TN
Knoxville Superior Mold Remediation does mold remediation in Alcoa, TN, from the crawl space under a 1920s mill house to a finished basement in a newer split-level. We take the mold out of crawl spaces, basements, attics and bathroom walls, clean and treat the wood, and keep a HEPA air scrubber running the whole time. But first we find the water. Dry wood doesn't grow mold.
Alcoa is a straight shot down Alcoa Highway from us, about 13 miles, and inspections get booked within one or two business days. In the old company neighborhoods it's mostly crawl space mold removal; down near the river it's more often basement mold removal. We've been under more than 2,000 crawl spaces in East Tennessee, and Alcoa's are some of the oldest. Heading east, we cover Seymour the same way.

Old Company Houses and Crawl Space Mold
Alcoa started as a company town. The aluminum company had 150 houses going up by 1914 and about 700 by 1920, laid out in Vose, Springbrook, Bassel and Hall. Plenty of them still stand. You can see their age best from underneath, flashlight in one hand.
Mill Houses in Springbrook and Vose
The early houses sit on piers or crawl spaces so short you work on your elbows. Their floor joists are old-growth wood that's been breathing damp air for a hundred years. We find mold on the joists and the subfloor, and now and then soft wood at the sill plate. Every time we open one up we find somebody's 1950s patch job too.
Post-War Ranches and Split-Levels
Once the company sold its houses to workers in the early 1950s, ranches and split-levels filled the gaps. A lot of them have a crawl space under one half and a basement or garage under the other. Water finds the low half. So does the mold.
Living Near the Little River
The Little River runs through the east side of Alcoa on its way to the Tennessee River near Louisville. Near the river and the creeks that feed it, the ground stays wet long after a storm and the water table comes up. Low lots soak it in. Their basements and crawl spaces take on water through the floor and the walls, slowly, every spring.
Then there's the air. The Knoxville area averages about 71.5% relative humidity and 76% in August, with just under 52 inches of rain a year. The EPA says to dry wet materials within 24 to 48 hours. A crawl space with a dirt floor and open vents never gets there by itself. It just stays a little damp, all summer long, and that's plenty.
Is basement mold common in Alcoa homes?
Yes, especially in older homes on low lots near the Little River and its creeks. Block basement walls let ground water seep through after heavy rain, and finished walls trap it. Look for white crusty deposits on the block, peeling paint, a musty odor and dark spots at the bottom of drywall.
When water is coming through the wall, we talk about the fix before the cleanup. Sometimes it's a ten-dollar downspout extension. Sometimes it's an interior French drain and a sump pump. Bleach on that wall would be mowing dandelions: fine on Saturday, back by Thursday.
Stored boxes, old carpet and paneling in a damp basement often hold more mold than the walls do. Porous things like cardboard and carpet usually have to go. Hard items like plastic bins and metal shelves can be cleaned and kept.

Mold Removal Services We Offer in Alcoa
The jobs Alcoa homeowners and landlords call us for, most common first.
Basement Mold Removal
We cut out moldy drywall and remove wet carpet pad, then clean the block or concrete and treat it. A HEPA air scrubber runs the whole time. If water seeps in, we can drill weep holes in the block. An interior French drain and a sump pump carry the water out.
Crawl Space Mold Removal
Under the older Alcoa houses we bag out the old insulation and debris and clean the floor joists and subfloor. Then the wood gets RMR-86 and RMR-141. Tight crawl spaces take longer. We price that in up front, not halfway through.
Water Damage Mold Cleanup
After a burst pipe or a leaking water heater, you've got 24 to 48 hours before mold gets going. We pull the water out, run dehumidifiers, and map the wet areas with a moisture meter and thermal imaging. Anything that already grew mold comes out. Fast beats perfect here.
Attic Mold Removal
Dark spots on the roof sheathing usually mean warm, wet air is getting into the attic, often from a bathroom exhaust fan with no outside vent. We clean and treat the boards, remove damp insulation and show you the cause.
Crawl Space Vapor Barrier and Encapsulation
A new vapor barrier over the dirt stops ground moisture. Full encapsulation goes further. It adds a sealed liner, closed foundation vents and a crawl space dehumidifier. Ours carries a transferable lifetime guarantee.
Mold Testing for Rentals and Home Sales
Landlords and sellers in Alcoa usually need proof, not promises. You get a written moisture log with the reading at every spot we tested, before and after, plus photos. When a buyer's side asks for lab air sampling, we can set that up too.
Mold Remediation in Alcoa: FAQ
Can you remove mold from a house on piers?
Yes. Houses on piers or very short crawl spaces take more time because there is less room to work, but the process is the same. We contain the area, remove moldy insulation and debris, clean and treat the wood, and check moisture before and after. Access affects the price, so we quote after looking.
How much does mold remediation cost in Alcoa?
Most jobs cost between $1,500 and $6,000, based on 2026 national price guides. A small closet or bathroom area costs less, often under $1,500. A whole crawl space with new insulation or encapsulation costs more. We give you a written quote after a free inspection, so you know the price first.
Do landlords in Alcoa use your services?
Yes, plenty. We've cleaned up rental houses and small apartment units all over Alcoa, usually after a plumbing leak or a tenant calling about a musty smell. We work around you and the tenant on timing. You get photos and a written moisture log for the property file, which helps if anyone asks later.
What causes mold in a basement near the river?
Ground water. On low lots near the Little River and its creeks, water in the soil pushes against basement walls and through the floor after heavy rain. Block walls let it through slowly. Add warm, humid air and poor airflow, and mold grows on drywall, carpet and stored boxes.
Should I test for mold before calling you?
Usually not. If you can see the mold, a test mostly tells you what you already know, and honestly that's money better spent on the fix. Testing earns its fee when you smell mold and can't find it, or after the cleanup to prove it worked. We'll say which one fits during the free inspection.
How soon can you come out to Alcoa?
Inspections are usually booked within one or two business days, and we can often come out the next day when it's urgent. Alcoa is about 13 miles from Knoxville, so travel is short. Send the form or call, and tell us what you're seeing and where in the house it is.
