Foundation Repair and Home Value: What Buyers and Sellers Need to Know

How foundation issues affect home value, disclosure requirements, and why a transferable warranty matters when selling.

7 min read · January 28, 2026

Foundation issues are one of the biggest concerns for home buyers. Understanding how repairs affect value — and how to present them — can make or break a sale.

Impact on Home Value

Unrepaired Foundation Issues

Can reduce home value by 10-15%. Many buyers will walk away entirely, and lenders may refuse to finance the purchase.

Professionally Repaired

With proper documentation and a transferable warranty, repaired foundations typically have minimal impact on value (0-5% reduction).

Disclosure Requirements

Most states require sellers to disclose known foundation problems and repairs. Failure to disclose can result in lawsuits after the sale. Always be upfront — a transferable warranty and professional repair documentation actually reassure buyers.

Tips for Sellers

→Get repairs done before listing — it's much harder to sell with known issues
→Choose a contractor with a transferable warranty
→Keep all documentation: engineer reports, repair plans, warranty certificates
→Provide the buyer with maintenance guidelines to keep the warranty valid
→Consider getting a post-repair engineer letter confirming the foundation is stable
