Water damage restoration cost in Knoxville: what the numbers include
Per-square-foot prices cover getting the water out and the structure dry. Rebuilding what was ruined is a second bill, and most surprises come from there.
Published guides put professional water extraction and drying at roughly $3.10 to $12 per square foot, depending on how contaminated the water is; HomeAdvisor's average for a whole job is $3,868 (range $1,383–$6,369). Those are national figures. We looked for a dated, Knoxville-specific restoration price list and didn't find one, so treat everything here as a starting point for comparing local quotes.

The sources don't agree with each other, which is why a single "average" is misleading. Here is what each one publishes, per square foot:
| Category | HomeAdvisor | Angi | HomeGuide |
|---|---|---|---|
| 1 — clean (burst supply pipe) | $3.50 | $3.10 | $4–$6 |
| 2 — gray (washer or dishwasher overflow) | $5.25 | $4.65 | $6–$9 |
| 3 — black (sewage, flood water) | $7.50 | $6.60 | $9–$12 |
National published estimates; the Angi column comes from its Chicago cost page. Clean water left sitting can degrade to a higher category, so the price can climb while you wait.
What per-square-foot prices leave out
Those rates usually stop at dry. Replacing damaged materials is priced separately:
| What got wet | Published national range |
|---|---|
| Drywall replacement | $1.50–$3 per sq ft; $2–$6 including demolition |
| Flooring, by room | $1,200–$5,000 per room |
| Flooring, by area | $2–$50 per sq ft |
| Hardwood | $8–$100 per sq ft |
| Mold remediation, if drying came late | $10–$25 per sq ft; about $1,125–$3,757 per job |
HomeAdvisor, HomeGuide and Angi. The plumber's bill for the failed pipe is separate too — see emergency plumber cost in Knoxville.
Crawlspaces and subfloors
None of the published guides we checked prices a crawlspace or a soaked subfloor as its own line. That matters in a house where the supply lines run under the floor: the visible room may be 150 square feet while the wet area underneath is larger.
The industry's drying classes explain why it costs more. Class 1 is the least water to evaporate; Class 4 is water bound in dense materials that need specialty drying. Published whole-job ranges by class run from $150–$500 for Class 1 up to $1,000–$3,000 (HomeAdvisor) or $5,000–$15,000 (HomeGuide) for Class 3. That five-fold gap between two sources for the same class is the best argument for getting an itemized quote.
Ask the crew to write the crawlspace as separate lines: water removal, wet insulation removed, drying equipment, and any subfloor replacement.
Two worked examples
Both use only the national ranges above. They show how a bill stacks up, not what you will pay.
1. Burst supply pipe, 300 sq ft wet, clean water.
- Extraction and drying: 300 × $3.10 = $930, up to 300 × $6 = $1,800
- Drywall, 120 sq ft: 120 × $1.50 = $180, up to 120 × $6 = $720
- Cleanup total: $1,110 to $2,520
- Pipe repair, published Knoxville estimate: $748–$2,991, which brings the event to $1,858–$5,511
2. Sewer backup, 200 sq ft wet, Category 3.
- Extraction and drying: 200 × $6.60 = $1,320, up to 200 × $12 = $2,400
- Flooring in one room: $1,200 to $5,000
- Total: $2,520 to $7,400

How the job is billed, and what to ask
Published guides quote this work two ways — by the square foot or as a whole-job price by class — and a quote may use either. Professional drying commonly takes about 1 to 7 days, so the length of the job is a cost question, not just a scheduling one.
- Is the price per square foot, per day of equipment, or a fixed total?
- Which water category and class are you assuming, and why?
- What happens to the price if drying takes longer than planned?
- Is demolition and haul-off included? Is rebuilding?
- Will you give me moisture readings and photos for my insurer?
Where insurance comes in
A standard homeowners policy generally covers sudden, accidental water from plumbing, but not the repair of the pipe that failed, and you pay your deductible first. If the cleanup in example 1 came to $2,520 and your deductible were $1,000, the most the policy would pay toward it is $1,520. On a small Category 1 job, the claim may barely clear the deductible.
Example 2 is a different story: sewer and drain backup is excluded unless you bought a water backup endorsement, and creek or river flooding needs a separate flood policy.
What the adjuster will want:
- Photos and video of the source, the waterline, floors, walls and belongings, taken before cleanup
- Receipts for cleanup and temporary repairs
- The itemized restoration estimate, with extraction and drying separated from rebuild
- The damaged items themselves — call your insurer before discarding anything
