Flooded basement cleanup costs an average of $4,000, with a typical range of $2,000 – $7,000, according to Angi, HomeAdvisor, and Fixr.1,2,3 Angi and HomeAdvisor are corporate siblings and publish identical headline figures, including $1,500 – $15,000 extremes; matching figures between the sibling sites alone don’t establish independent corroboration.1,2 Fixr (updated January 2025) separately publishes the same $4,000 average and $2,000 – $7,000 range, scoping its average to full remediation of a 500 – 800 sq.ft. basement with 2 feet of water and category 2 damage, with a $1,000 low end and the same $15,000 high end; these are separately published figures, and the pages state no shared sourcing.3 Prices below are national averages*.

Safety first. CDC guidance for reentering a flooded home: if you can turn off the main power from a dry location, do so before entering; if you must enter standing water to reach the switch, call an electrician instead. Never turn power on or off, or use an electric tool or appliance, while standing in water, and have an electrician check the system before restoring power. CDC also warns that a flooded home may be contaminated with mold or sewage; if it has been closed up for several days, assume mold is present.4

What the sources say

Source Headline figures Notes
Angi (2026 data, updated Oct 2026) $4,000 average; most homeowners $2,000 – $7,000; low $1,500; high $15,000 Corporate sibling of HomeAdvisor; headline figures match HomeAdvisor’s and Fixr’s range and average
HomeAdvisor (2026 data, updated Jun 2026) $4,000 average; normal range $2,000 – $7,000; low $1,500; high $15,000 Sibling-published figures match Angi’s; matching figures alone don’t establish independent corroboration
Fixr (updated Jan 2025) $4,000 average scoped to a 500–800 sq.ft. basement with 2 ft of water and category 2 damage; average range $2,000 – $7,000; low $1,000; high $15,000 Separately published, pages state no shared sourcing; its $1,000 low end differs from the siblings’ $1,500 without explanation

Cost by water contamination category

Angi and HomeAdvisor publish identical figures for the three water contamination categories (Angi labels them clean, gray, and black water; HomeAdvisor labels them categories 1, 2, and 3):1,2

Water category Cleanup cost (Angi/HomeAdvisor)
Category 1 (clean water) $1,500 – $3,500
Category 2 (gray water from appliances, showers, or sinks) $3,000 – $7,000
Category 3 (black water: sewage or contaminated floodwater) $7,000 – $15,000

These are the publishers’ labels for contamination level, not for the water’s origin. CDC warns that floodwater can carry germs and other contaminants, and even sharp debris, so water that entered the home from outside should not be treated as clean simply because it started as rain.5

HomeAdvisor notes these figures cover cleaning only; repairing the water damage afterward is additional, at $1,300 – $5,500 or more.2

Fixr prices the same three categories differently, and adds a per-square-foot rate for each:3

Category Per sq.ft., labor included (Fixr) Average cost, labor included (Fixr)
Category 1 $3.50 – $4.25 $1,000 – $5,000
Category 2 $4.10 – $5 $4,000 – $8,000
Category 3 $6.25 – $7.25 $10,000 – $15,000

Cost by water damage class (Fixr)

Fixr also prices by water damage class, a separate scale describing how much material is affected:3

Class Average cost, labor included (Fixr)
Class 1 $1,000 – $3,000
Class 2 $3,500 – $6,000
Class 3 $4,000 – $8,000
Class 4 $10,000 – $15,000

Cost by basement size

Angi and HomeAdvisor both put cleanup at $3 – $7 per square foot, but their size tables differ slightly:1,2

Basement size (sq.ft.) Cost (Angi) Cost (HomeAdvisor)
500 $1,500 – $3,800 $1,500 – $3,500
1,000 $3,000 – $7,500 $3,000 – $7,000
1,500 — $4,500 – $10,500
1,800 — $5,400 – $12,600
2,000 $6,000 – $15,000 $6,000 – $14,000

The siblings state the same per-square-foot rate yet publish slightly different size rows; the difference is unexplained, so each column keeps its own publisher’s figures. Fixr publishes its own size table with labor included:3

Basement size (sq.ft.) Cost, labor included (Fixr)
500 $1,750 – $3,620
1,000 $3,500 – $7,250
1,200 $4,200 – $8,700
1,500 $5,250 – $10,870
1,800 $6,300 – $13,000

Repairs and restoration after cleanup

Angi prices the restoration work a flooded basement often needs:1

Item Scope Cost (Angi)
Flooring Removal and replacement (carpet, laminate, tile) $1,000 – $5,000
Drywall Tear-out and reinstall per room $500 – $2,500
Insulation Replace water-damaged insulation $400 – $1,200
Baseboards Replace or restore wood trim $200 – $800
Cabinetry Remove and reinstall cabinets $800 – $3,500

HomeAdvisor publishes a similar post-flood repair table; its drywall, mold, and foundation figures match Angi’s (sibling-published):2

Item Cost (HomeAdvisor)
Carpet replacement $1,000 – $5,000
Mold or mildew removal $500 – $6,000
Leak repair $250 – $1,000
Drywall repair $500 – $2,500
Foundation repair $1,000 – $10,000

Fixr prices flood-related repairs separately:3

Type of repair Cost, labor included (Fixr)
Carpet cleanup $75 – $300
Electrical repair $200 – $600
Water-damaged wood repair $200 – $2,000
Restarting a furnace after a flood $250 – $1,500
Leaking basement repair $250 – $8,000
Flood-cut drywall repair $300 – $485
Foundation issues $5,000 – $15,000

Note the differing scopes: Fixr’s carpet row is cleanup, while HomeAdvisor’s is replacement, and Fixr’s foundation row covers structural repairs priced well above the siblings’ foundation-crack figure. See our guides to water damage restoration, mold remediation, and basement waterproofing for those projects.

Labor, assessment, and equipment

Angi reports $50 – $150 per hour for the specialists involved (restoration pros, plumbers, electricians, mold remediators), initial assessment and inspection fees of $100 – $500, and emergency water extraction or pump-out at $300 – $2,000 depending on volume.1 It prices drying equipment separately: dehumidifiers at $100 – $300 per week and air movers at $50 – $150 per week.1

National cleanup services (Fixr)

Fixr publishes average totals for the two largest national providers, labor and materials included: ServiceMaster at $3,000 – $10,000 and Servpro at $3,500 – $15,000.3
