The published range
Angi, How Much Does Water Damage Restoration Cost? puts plumbing leak water damage at $350–$4,000. 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 passes the $3,868 national average by $132.
By midpoint ($2,175) it ranks 1st of the 8 damage areas the guide prices. No area costs more in the guide. Plumbing covers the leak itself, from a pinhole to a burst pipe; the guide prices a burst pipe with its damage separately.
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 plumbing leak range covers about 1,143 sq ft of clean-water drying but only 533 sq ft of black-water work.
A burst pipe with the damage it causes is printed at $1,000–$4,000, and a sump pump with installation at $1,200.
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 crawl space location at $500–$2,000.
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 4 times the top of this range.
