The published range

Angi, How Much Does Water Damage Restoration Cost? puts basement water damage at $500–$2,800. For a whole water damage job the guide's national average is $3,868, with most jobs between $1,383 and $6,369 and the full span running $450–$16,000. Its top end stays $1,068 under the national average.

By midpoint ($1,650) it ranks 2nd of the 8 damage areas the guide prices. Plumbing leak is the next area up and Flooring the next down. The basement line covers ordinary basement water; a basement that floods is priced in a separate guide, set out below.

Water type changes the rate. The guide prints $3.50 per sq ft for clean water (Category 1), $5.25 per sq ft for gray water (Category 2) and $7.50 per sq ft for black water (Category 3, includes sewage). Arithmetic on those rates: the top of the basement range covers about 800 sq ft of clean-water drying but only 373 sq ft of black-water work.

The flooded-basement guide (Angi) prices a flood separately: $4,000 on average, $2,000–$7,000 typical, and by water type clean water $1,500–$3,500, gray water $3,000–$7,000 and black water (sewage) $7,000–$15,000. By floor size it lists 500 sq ft at $1,500–$3,800, 1,000 sq ft at $3,000–$7,500 and 2,000 sq ft at $6,000–$15,000, which is the $3 to $7.50 rate applied to the floor area.

If the area is not dried in time, the problem changes. “It is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth.” (U.S. EPA, A Brief Guide to Mold, Moisture and Your Home) The guide's own mold line is $1,200–$3,800, and the mold guide prices the related basement location at $500–$3,000.

Insurance industry figures put the area range in context: the Insurance Information Institute reports an average water damage and freezing claim of $15,400 for 2019-2023, about 6 times the top of this range, which reflects claims that span several areas at once.
