Foundation & Repairs
Foundation cracks, slab leaks, sump pumps, water lines, hazard remediation
This is the unglamorous category — the work nobody wants to pay for and everybody eventually does. Foundation cracks, slab leaks, crawl space moisture, failing sump pumps, well and water line replacement, and hazard remediation like asbestos and lead paint all live here. None of it makes a house prettier. All of it protects the value of everything else you own, and most of it gets dramatically more expensive the longer it waits.
The hard part with structural and water-intrusion work is that quotes vary wildly, because diagnosis is half the job. A hairline crack that only needs epoxy injection and a crack that signals differential settlement look similar to a homeowner and cost ten times different. These guides explain what drives each price — depth, access, soil, whether piers are involved, whether remediation triggers permits and testing — and what a legitimate scope of work should include before you sign. When in doubt, pay for an independent inspection before you pay for a repair.

How to use the foundation & repairs numbers on this page
Every cost figure we publish is a range, not a quote. National averages are a starting point for budgeting and for spotting a bid that's wildly out of line — they are not a substitute for getting three written estimates from licensed contractors or lenders in your own market. Labor rates, permit fees, material availability and local code requirements move these numbers more than anything else, which is why our project pages break costs down state by state instead of quoting a single national figure.
If you're early in the process, start with a calculator to get a ballpark, then read the guide that matches your situation to learn which line items are negotiable and which ones aren't. If you're already holding quotes, use the guides to check what should be included in the scope of work before you sign anything.
