Mold Remediation in Seymour, TN
Knoxville Superior Mold Remediation does mold remediation in Seymour, TN on whatever you've got: a 2005 two-story, a skirted manufactured home or a farmhouse older than anybody on the road. We pull mold out of crawl spaces, walls, bathrooms and attics, treat the wood and run HEPA filtration while we work. Then we deal with the damp. A new vapor barrier or a sealed crawl space keeps it from coming back.
Seymour is about 13 miles down Chapman Highway from Knoxville, an easy run for our family crew. We do about 150 mold jobs a year, most of them under the house. Most of what we do there is crawl space mold removal, and on the damp lots, crawl space encapsulation. We do mobile and manufactured homes too, which not everybody will. Keep going east and we're in Sevierville the same week.
Containment on every job

Seymour's Mix of Houses
Seymour went from 8,850 people in 2000 to 14,705 in 2020, and you can see it from the road: new subdivisions, manufactured homes and old farmhouses, sometimes all on one mile of pavement. Each kind of house gets mold its own way. We've seen all three in a single afternoon.
Manufactured Homes and Skirted Crawl Spaces
A manufactured home sits on piers with vinyl skirting around the bottom, and under there it's usually bare dirt and dead air. Water from the ground and from the AC lines collects on the underside of the floor and inside the belly wrap. Mold follows. In our experience the ductwork under these homes is where the musty smell starts.
Newer Subdivision Homes
The 1990s and 2000s houses mostly sit on vented crawl spaces with a thin sheet of plastic on the dirt. Twenty years and a few plumbers later, that plastic is torn, bunched up or gone. The floor joists above it pick up mold, slowly, one muggy August at a time.
Older Farmhouses
Old farmhouses around Seymour sit on stone or block piers over a partial crawl space, with wood that's been damp since before the highway was paved. We look hard at the sill plate and the subfloor. Rot and mold tend to show up together, and we'll tell you which is which.
Hollows, Slopes and Ground Water
Seymour sits in a rolling valley, Bluff Mountain to the south and the Bays Mountain ridge to the north, so water is always on its way downhill. Houses in the low spots catch it. After a hard rain it runs under the house and soaks the dirt, and the crawl space stays damp for a week.
The Knoxville area runs about 71.5% relative humidity on average and just under 52 inches of rain a year. The EPA wants indoor humidity below 60%. A crawl space with open foundation vents and wet clay under it sits way above that all summer. That's the whole trick to mold: give it damp, it grows.
Does homeowners insurance cover mold in Seymour?
Sometimes. Most homeowners policies cover mold only when it comes from a sudden covered event, like a burst pipe or a failed water heater, and not from long-term humidity or a slow leak. Your adjuster makes the call. We provide photos, moisture readings and a written scope to support the claim.
Manufactured home policies vary even more, so read yours or call your agent before the work starts. We can wait to start until you hear back.
How We Handle a Seymour Crawl Space
We've been under more than 2,000 crawl spaces in East Tennessee, and every one starts the same way: find the water first. We take moisture readings, text you photos from under the house so you see what we see, and only then write the quote.
On work days it's containment, out with the moldy stuff, clean and treat the wood, HEPA air scrubber humming the whole time. At the end we take every reading again. You get a written moisture log: the reading at every spot we tested, before and after. Keep it. Buyers like it.

Mold Removal Services We Offer in Seymour
What Seymour folks call us about, most common first. Number one isn't close.
Crawl Space Mold Removal
Containment first, then out come the moldy insulation and debris. We clean the floor joists and subfloor. Then the wood gets RMR-86 and RMR-141. Before we pack up, a post-remediation evaluation checks the work. You get the readings.
Mobile Home Mold Treatment
Under a manufactured home we pull the wet insulation out of the belly, treat the underside of the floor and check the ductwork for mold and condensation. Inside, moldy wall panels near leaks and windows get cleaned or cut out. Yes, even the one behind the washer.
Crawl Space Encapsulation
Encapsulation covers the dirt and walls with a heavy liner. It also closes the foundation vents and adds a crawl space dehumidifier. It keeps the space dry all year and comes with a transferable lifetime guarantee.
Bathroom and Wall Mold Removal
Mold around tubs, showers and windows often means a leak or poor ventilation. If it's on the surface, we clean it. If it's in the drywall, the moldy section comes out and we find the water behind it.
Attic Mold Removal
Attics in newer homes grow mold on the roof sheathing when bathroom fans vent into the attic or soffit vents get blocked by insulation. We clean and treat the sheathing and replace wet insulation.
Mold Inspection
A free inspection with a moisture meter and thermal imaging finds where the water is going. If you need proof for a sale or an insurance claim, we can add air sampling sent to a lab.
Mold Remediation in Seymour: FAQ
Do you remove mold under mobile homes in Seymour?
Yes. We work under manufactured and mobile homes all the time. We remove wet belly insulation, treat the underside of the floor, check the ductwork and lay a new vapor barrier on the ground. The skirting stays on, and we cut a small access panel if there isn't one already.
How much does mold remediation cost in Seymour?
Most Seymour jobs fall between $1,500 and $6,000, based on 2026 national price guides. A small bathroom area often costs under $1,500. A whole crawl space with a new vapor barrier or encapsulation costs more. You get a written quote after a free inspection, before any work begins.
Is Seymour in Sevier County or Blount County?
Both. Seymour is an unincorporated community that crosses the line between Sevier County and Blount County. We serve the whole area either way. If any rebuild work after the mold cleanup needs a permit, it goes through the county your home is in, not a city office.
Why does mold keep coming back in my crawl space?
Because the moisture never left. A torn vapor barrier, open vents in summer or water running in from the slope keeps the wood damp, and mold grows right back. Honestly, cleaning alone is mowing dandelions. Fix the water source first, then dry the space with a barrier or encapsulation.
How long does a crawl space job take?
Most Seymour crawl spaces take one to three days. Mold removal on an average home takes one to two days, and adding a vapor barrier or full encapsulation adds about a day. Low or tight crawl spaces take longer, and we include that in the quote so there are no surprises.
