Look for a company that performs a free, thorough inspection and explains the cause of damage — not just the fix. Check Google ratings for reviews mentioning honesty, thorough diagnostics, and whether the problem recurred after repair. Be cautious of companies that only offer one repair method.
Minor crack repairs (epoxy injection) cost $500–$2,500. Pier installation for significant settling runs $1,000–$3,500 per pier; most jobs require 8–15 piers. Full basement waterproofing systems run $5,000–$15,000. Get three quotes — pricing varies significantly by repair method.

Crack injection repairs take half a day to a full day. Pier installation typically takes 1–3 days. Full perimeter drainage and waterproofing systems take 3–7 days depending on basement size.
Ask whether the cause of movement is ongoing (drainage, tree roots, soil shrinkage), what repair method they recommend and why, whether they offer a lifetime warranty, what happens if piers are needed after the initial repair, and if the work is permitted.
All listings are sourced from Google Business Profiles and ranked by real Google ratings and review volume. No payment changes rankings. Confirm contractor licensing, insurance, and warranty terms directly before signing.
Invoke the written warranty immediately — most reputable companies offer transferable lifetime warranties. File with your state contractor licensing board if the contractor was licensed. Get a second professional opinion before any additional work is done.
