What happens if you’ve snagged your dream home only to discover the seller didn’t disclose foundation problems? Some homeowners hide foundation issues, such as hairline cracks or bowed walls, to maintain their property’s value or speed up a sale. They might downplay the problems or omit them from their disclosure altogether.

Our guide explains what to do if you discover foundation problems at any point in the home-buying process.

Should Sellers Disclose Foundation Problems?

Sellers are generally expected to disclose foundation problems, as these can impact the property’s value and safety. Real estate transactions almost always include a seller disclosure form where they should list known home defects, including foundation problems.

We recommend researching your state’s seller disclosure laws before you start the home-buying process so you know your rights and responsibilities as a homebuyer. You can find this information on your state’s real estate commission website.

Of course, doing your due diligence as a buyer is also important. Even if the seller provides a disclosure, you shouldn’t take their claims at face value. Hire a home inspector or structural engineer to assess the property—especially the foundation. Sellers who intentionally conceal known foundation problems could face legal consequences.

When we asked a team of experts about red flags when buying a house, their first piece of advice was not to waive a professional home inspection. Check out the video below to learn more about what the experts look for and what they consider dealbreakers:

Major Foundation Issues That May Impact a Sale

Major foundation issues can significantly impact the safety and resale value of a home. They can also make it difficult to get homeowners insurance or secure a mortgage. If you have any concerns, we recommend hiring a structural engineer to inspect the foundation instead of relying solely on a home inspector and the seller’s disclosure statement. Here’s what a structural engineer will look for:

• Signs of previous repair: A structural engineer may recognize signs that the foundation previously underwent repairs or experienced extensive damage in the past, which could be a red flag.
• Foundation sinking or upheaval: The foundation sinking or heaving upward due to changes in the soil may cause some foundation cracks.
• Stress cracks: Long cracks on foundation walls—particularly wide or expanding cracks—could indicate that pressure from the soil or water is pushing the foundation inward and compromising its structural integrity. Horizontal cracks are often the most concerning, but stress cracks can also be vertical or diagonal.
• Misaligned doors and windows: Doors and windows that do not open and close properly could be signs of a shifting foundation. Gaps between the wall and the floor or ceiling can also suggest foundation movement.
• Water damage or drainage issues: Water stains, mold, mildew, musty odors, peeling paint, rusty metal, and wood rot could all indicate serious moisture issues. These issues may be most evident in the basement or crawl space of the home.

If the structural engineer finds serious problems during their during their foundation inspection, you may need to reconsider purchasing the home or postpone closing until the seller has repaired the issues.

Minor Foundation Issues That May Not Impact a Sale

Every home will show signs of wear and tear over time, so minor foundation issues may not be a dealbreaker. Here are some examples:

Minor Sett

ling

All houses will settle over time, and building materials may expand and contract. As long as the change is minor and uniform, it may be harmless.

Hairline Cracks

Not all foundation cracks are cause for concern. Thin cracks may be more of a cosmetic problem with a simple fix rather than signs of a major structural issue.

Dampness

Although it’s a good idea to address any moisture issues to keep them from escalating and causing serious water damage, small leaks may not require immediate repair.

Imperfect Floors

Slightly uneven flooring could point to normal settling or poor installation rather than a serious foundation problem. Fixing cracks in concrete or tile could be a simple cosmetic repair.

Hiring a structural engineer is the safest way to determine the severity of a problem and the urgency of addressing it. Some foundation issues that do not require immediate repair could escalate over time, so it’s important to monitor any issues and address them if they worsen.

Can I Buy a House That Needs Foundation Repair?

You can buy a home that needs foundation repair, but that decision comes with certain risks and challenges. The most obvious drawback is the potential cost of foundation repairs. Many repairs only cost about $2,000–$7,500*, but major issues could easily cost $15,000–$25,000 or more to fix.

Foundation problems can be expensive to repair and cause collateral damage, such as misaligned doors and water damage. Research how to repair foundation cracks or any other relevant issue and decide whether this house is worth the extra trouble.

What To Do if You Discover Foundation Problems

Whether you’re still in the buying phase or have already settled into your new home, discovering foundation problems can be unsettling. Here’s what to do in each scenario:

If You Haven’t Purchased the Home Yet

If you, your realtor, or your home inspector spot foundation problems before you seal the deal, your first step should be to hire a structural engineer. You need a detailed assessment of the problem, recommended repairs, estimated cost, and potential foundation repair costs.

You should also check local and state guidelines on seller disclosures to understand your rights and leverage. Some states have strong protections for homebuyers that require the seller to disclose any material defects. In that case, now that the seller knows about the issue, they would have to disclose it to any future potential buyers.

If the foundation problems are extensive and the seller is unwilling to negotiate, it may be in your best interest to walk away.

If You Already Own the Home

If foundation issues arise after your home purchase, don’t panic. Start by consulting a structural engineer to determine the severity of the problem and the best remedy. Once you have a clearer picture of the situation, explore your home warranty or homeowners insurance policy to see if they will cover the repairs. If you need to pay for repairs out-of-pocket, explore financing such as a home equity line of credit or a renovation loan.

If you suspect the previous owner knew about the problems but did not disclose them, consult a real estate attorney for legal advice. You may be able to sue the seller for breach of contract or their realtor for misrepresentation due to undisclosed defects. A law firm specializing in tort claims can explain any relevant laws and help you seek legal recourse if possible.

Remember that foundation issues often go hand-in-hand with other problems, such as plumbing leaks or water damage. Raising these issues early on will help prevent further complications and protect your investment.

What To Do if the Seller Didn’t Disclose a Major Foundation Problem

Dealing with a major foundation problem as a new homeowner can be daunting, but you should be methodical. Here’s what to do:

• Document everything: Keep a meticulous record of all noticeable foundation issues, including photographs, notes, and any professional assessments or quotes you receive. Review any disclaimers or seller disclosures from your home purchase to verify that the seller did not disclose the foundation issue.
• Consult a structural engineer: Before jumping to conclusions, get a professional opinion regarding the extent of the problem and whether it’s a preexisting issue or a recent development.
• Seek evidence of concealment: Look for signs that the sellers may have deliberately concealed the problem. Examples include fresh paint over cracks, strategically placed decor, recently moved furniture, or conversations with neighbors.
• Initiate amicable communication: Before taking any drastic steps, reach out to the seller or their real estate broker. Express your concerns, provide evidence, and seek a resolution. They might be unaware of the problem or willing to contribute to repair costs.
• Consult with a real estate attorney: If amicable communication doesn’t yield results, consider seeking legal advice. A real estate attorney can help you identify the responsible party, possible legal remedies, and the likelihood of success given nondisclosure laws and the statute of limitations in your state.
• Send a demand letter: Before filing a lawsuit, work with your attorney to send a formal demand letter that outlines the issue, the evidence, and your expectations. This step shows your seriousness and may prompt the seller to offer compensation or repairs.

Remember that while legal avenues are available, they should be a last resort. Open communication, detailed evidence, and professional counsel are key.

Our Conclusion

Undisclosed foundation problems can be distressing, especially for first-time homebuyers. However, not all cracks and moisture problems spell certain disaster. The seller may be willing to fix minor foundation issues prior to closing or negotiate a lower price. For issues discovered after the home sale has been finalized, we recommend hiring a structural engineer and consulting an experienced real estate attorney to explore your options.
