Crawl space repair in Wilmington runs from about $400 for cleanup to $12,000 or more for structural work. The typical whole-crawl-space project lands at $4,200–$14,000. The price depends almost entirely on which problem you have, not on square footage.
Cost by problem
"Crawl space repair" is a category, not a job. These are the individual pieces, roughly in the order they usually have to happen.
- Cleanup and debris removal — $400–$1,500
- Vapor barrier / liner — $1,500–$4,000
- Vent sealing — $300–$1,000
- Dehumidifier installed — $1,200–$2,500
- Drainage and sump — $1,500–$5,000
- Mold removal and wood treatment — $500–$4,000
- Structural repair (sistering, girders, jacks) — $800–$12,000+
Why sequence changes the total
The same list of items costs materially more if done in the wrong order. Drainage retrofitted under a finished liner means lifting and re-terminating the liner, which is most of the cost of installing it. Structural repair after encapsulation means the same.
A quote that prices the liner first and leaves drainage as a later option is not cheaper — it is more expensive, deferred.
The bottom line
Get the problem identified before you compare prices. Two quotes for "crawl space repair" can describe completely different work, and the cheaper one is frequently the one that skipped drainage.
