What affects the cost of basement waterproofing
What a basement or crawl-space waterproofing job costs depends on the house and the water problem, not on a single typical price. We do not publish job prices here because they vary too widely to be useful. Use the factors below to compare written quotes.
Factors that usually change the quote
- Whether the work is interior drainage and a sump, exterior excavation and a membrane, crawl-space moisture control, or yard grading only
- How easy it is to reach the foundation, including finished interiors, decks, walkways and tight side yards
- How much soil, concrete or finish material has to be removed and put back
- Whether a sump, battery backup, or discharge line to a legal outlet is included
- Permits, if your city or county requires them, and any engineering the contractor says is needed
Ask each company for a written scope that lists what is included, what is not, and how water will be carried away from the house. A lower number that leaves out discharge, restoration or a backup pump is not a like-for-like comparison.
