What mold remediation costs
General cost ranges for mold work in the Knoxville area, and what moves the price.
What drives the price
Mold pricing is mostly about size, location, and the moisture source behind it. A small bathroom spot is inexpensive; a crawl space or a wall cavity fed by an ongoing leak costs more because the source has to be fixed too.
The ranges below are general planning figures, not quotes. The provider you are connected with sets actual pricing after seeing the situation.
Typical ranges
| Situation | General range | Note |
|---|---|---|
| Small surface area (bathroom, one wall) | $300–$1,000 | Often manageable once the source is fixed |
| Crawl space treatment | $1,500–$5,000 | Depends on size, access, and encapsulation |
| Basement / lower level | $2,000–$6,000 | Higher when water entry must be corrected |
| Whole-home or extensive growth | $6,000+ | Priced case by case after inspection |

Why local conditions matter here
Knoxville averages about 50 inches of rain a year and monthly relative humidity generally runs about 70–78%, and summer afternoons in July and August can feel heavy. That combination keeps crawl spaces and lower levels damp longer than in a drier climate, which is why source correction — not just surface cleaning — is usually the larger part of the cost.
