Flooded basement cleanup cost: what the published numbers say
Short answer
Most published guides put flooded basement cleanup at $2,000 to $7,000, with Angi, Fixr and HomeAdvisor all stating a $4,000 average, roughly $3 to $7 per square foot. The water decides the price: clean supply water runs about $1,500 to $3,500, while sewage or floodwater (Category 3) runs $7,000 to $15,000 on Angi's figures. Full ranges stretch from about $1,000 to $15,000 or more, and repairs such as drywall, flooring and mold work are priced on top.

How much does flooded basement cleanup cost?
Four widely cited guides publish national figures for cleaning up a flooded basement. All four were checked on October 29, 2026; the table shows each source’s typical range and average, with the date the page itself shows.
| Source | Low | High | Average | Last updated |
|---|---|---|---|---|
| Angi | $2,000 | $7,000 | $4,000 | no date shown; accessed 2026-10-29 |
| HomeAdvisor | $2,000 | $7,000 | $4,000 | no date shown; accessed 2026-10-29 |
| HomeGuide | $1,600 | $12,000+ | not stated | no date shown; accessed 2026-10-29 |
| Fixr | $2,000 | $7,000 | $4,000 | 2025-01-31 |
The full ranges are wider than the typical ones. Angi and HomeAdvisor both say $1,500 to $15,000 overall, Fixr’s tables run $1,000 to $15,000, and HomeGuide’s $1,600 to $12,000-plus explicitly excludes repairs. Per square foot, Angi and HomeAdvisor say $3 to $7, Fixr says $3.50 to $7.25, and HomeGuide says $4 to $12 depending on the water category.
Forbes Home, which we compare on other cost pages, publishes no dedicated flooded-basement guide; its water damage figures are in our water damage restoration cost page, alongside the rest of our cost guides.
Why the numbers disagree
Three reasons, and they matter when you read a quote.
Scope. HomeGuide’s $4 to $12 per square foot covers extraction, drying and sanitizing but excludes repairs, which it prices separately (drywall $2 to $4 per square foot, carpet $2 to $8). The $4,000 averages from the other three appear to describe a complete typical cleanup. A number that includes tear-out and one that stops at drying can differ by thousands on the same basement.
Assumptions. Fixr states its $4,000 average assumes about 2 feet of water in the basement. The others do not state a depth. A slab with an inch of clean water and a basement with two feet of floodwater sit at opposite ends of every range.
Shared data. Angi and HomeAdvisor are owned by the same company and publish matching figures: the same $4,000 average, the same $2,000 to $7,000 typical range, the same category prices. Agreement between them is one dataset, not two independent estimates. HomeGuide, whose figures come from its own contractor network, lands meaningfully higher at the top end.
What drives the price up or down
The water category. The biggest single factor. Water categories run from clean supply water (Category 1) through gray water (Category 2) to sewage and outside floodwater (Category 3), and the price roughly doubles twice across them.
| Water category | Angi / HomeAdvisor (total) | HomeGuide (per sq. ft.) | Fixr (total) |
|---|---|---|---|
| Category 1 (clean) | $1,500–$3,500 | $4–$6 | $1,000–$5,000 |
| Category 2 (gray) | $3,000–$7,000 | $6–$9 | $4,000–$8,000 |
| Category 3 (black) | $7,000–$15,000 | $9–$12 | $10,000–$15,000 |
A basement flooded from outside, or through a floor drain, is Category 3 regardless of how clear the water looks. See sewage backup in a basement for what that means in practice.
Depth. HomeAdvisor says more than about an inch of water across the basement likely means professional pumping, and HomeGuide notes each added inch extends extraction and the drying timeline. Fixr’s average assumes 2 feet.
Size. Angi prices a 500-square-foot basement at $1,500 to $3,800, a 1,000-square-foot basement at $3,000 to $7,500 and a 2,000-square-foot basement at $6,000 to $15,000.
Finished vs unfinished. An unfinished basement with a sealed slab is mostly a pump, rinse and dry job. A finished basement adds soaked drywall, insulation, carpet and trim: HomeGuide prices drywall repair at $2 to $4 per square foot and carpet at $2 to $8, while HomeAdvisor puts carpet work at $1,000 to $5,000 and drywall at $500 to $2,500. If wet materials sat past the 24-to-48-hour drying window, mold work is added on top; HomeGuide lists mold remediation at $15 to $30 per square foot.
Pump-out vs full restoration: what should be on the quote
A pump-out gets the water out. Restoration returns the basement to use. Quotes go wrong when the homeowner thinks they bought the second and the contractor priced the first. Every quote should separate these lines:
| Line item | How it is priced | Published figures |
|---|---|---|
| Water extraction, drying and sanitizing | Per square foot | $3–$7 (Angi, HomeAdvisor); $3.50–$7.25 (Fixr); $4–$12 by category (HomeGuide) |
| Mud and debris removal | Included or hourly | Not separately priced in the four guides; confirm it is in scope |
| Tear-out of wet drywall, carpet, pad and insulation | Per square foot or lump sum | Often excluded from headline figures; HomeGuide prices repairs separately |
| Drying equipment | Per unit per day, with days listed | Not published per day in these guides; require unit counts and daily moisture readings |
| Antimicrobial treatment | Per square foot or lump sum | Required for Category 2 and 3; confirm it is listed, not assumed |
| Disposal fees | Lump sum | Ask; Category 3 debris can carry hauling charges |
| Repairs: drywall, flooring, trim, paint | Separate quote | Drywall $2–$4/sq. ft., carpet $2–$8/sq. ft. (HomeGuide); carpet $1,000–$5,000, drywall $500–$2,500 (HomeAdvisor) |
| Related trades if flooded | Separate quote | Electrical $50–$150/hr (HomeAdvisor); plumbing $45–$200/hr (HomeGuide); furnace restart $250–$1,500 (Fixr) |
If the basement flooded from outside, the cleanup steps themselves, cutting power safely, staged pumping so the walls do not crack, and the 48-hour drying clock, are in our flooded basement cleanup guide.
Who pays, and what to document
Where the water came from decides which policy, if any, responds: a burst pipe, a sewer backup and rising floodwater are three different coverage questions, explained in our water damage coverage guide. Whatever the answer turns out to be, photograph the water level and the contents before pumping, keep every receipt, and get the contractor’s scope in writing before demolition goes beyond what stopping the damage requires. We explain how the pricing works; for your own claim, ask your insurer, your state insurance department or a licensed public adjuster.
When to call a pro
- Water is more than about an inch deep across the basement. HomeAdvisor says professional pumping is likely at that point.
- The water came from a floor drain, toilet or outside flooding. That is Category 3 work with PPE and containment, not a shop-vac job.
- The power is still on and you cannot reach the main switch without entering water.
- Finished walls, insulation or carpet soaked up the water. Tear-out and drying equipment go beyond DIY.
- The space was wet longer than 24 to 48 hours, or mold already covers more than about 10 square feet (EPA's DIY limit).
Common mistakes
- Paying full-restoration prices for a pump-and-dry job. Get the scope in writing: extraction, tear-out, drying and repairs are separate line items.
- Comparing a clean-water quote against black-water prices. Category 3 work legitimately costs two to four times more in every published guide.
- Accepting a quote with no drying plan. Equipment counts, days on site and daily moisture readings should be listed, not bundled.
- Forgetting the repairs. Published cleanup figures mostly exclude rebuilding drywall, flooring and trim, which HomeGuide prices separately.
- Treating matching averages as independent confirmation. Angi and HomeAdvisor share an owner and publish the same figures.

Questions people ask
How much does it cost to pump water out of a basement?
Pumping alone is rarely priced separately in the published guides; extraction, drying and sanitizing are usually sold together at about $3 to $7 per square foot (Angi, HomeAdvisor) or $4 to $12 per square foot by water category (HomeGuide). For a minor clean-water puddle, HomeAdvisor notes a wet/dry vacuum rents for about $150 a day or costs about $250 to buy.
Why is sewage or floodwater cleanup so much more expensive?
Contaminated water, Category 3, requires protective equipment, containment, antimicrobial treatment and the disposal of porous materials it touched. Angi and HomeAdvisor put black-water basement cleanup at $7,000 to $15,000 versus $1,500 to $3,500 for clean water, and Fixr's per-square-foot rate nearly doubles from Category 1 to Category 3. The category also decides what must be thrown away.
Does basement size change the price much?
Yes, most guides price by area. Angi puts a 500-square-foot basement at $1,500 to $3,800 and a 2,000-square-foot basement at $6,000 to $15,000. Fixr's table runs from $1,750 to $3,620 at 500 square feet up to $6,300 to $13,000 at 1,800 square feet. Depth matters too: Fixr's $4,000 average assumes about 2 feet of water.
Will homeowners insurance pay for flooded basement cleanup?
It depends entirely on where the water came from. A burst pipe is handled differently from a sewer backup, which usually needs its own endorsement, and rising water from outside is flood, excluded from standard homeowners policies. Our guides to water damage coverage and sewer backup coverage explain the distinctions. Ask your insurer, your state insurance department or a licensed public adjuster about your policy.
