Michigan law requires disclosing past water intrusion even after repair, even after a settled claim, even in an as-is sale. What that means for buyers, what it requires of sellers, and who to call for each side of the transaction.

The part most homeowners get wrong
No, and this is the single most common misunderstanding in a Michigan home sale. The Michigan Seller Disclosure Act requires disclosing any evidence of water intrusion in a basement or crawl space, past or present — not whether a problem currently exists. A basement that flooded years ago, was fully repaired, and has been dry ever since still has to be disclosed, because the form asks whether there has ever been evidence of water, not whether there is a problem today.
The same logic applies to a settled insurance claim. If a claim was filed and paid for water damage, that claim history is itself evidence of past intrusion and must be disclosed, regardless of how completely the repair resolved the issue. And an “as-is” sale changes nothing about this duty — as-is governs who pays for a defect discovered after closing, not whether the seller had to mention a known one beforehand. A seller who knows the basement floods every spring and checks “no” on the form is exposed to a disclosure claim no matter what the purchase contract says.
| Scenario | Disclosure rule | Why |
|---|---|---|
| A basement flooded once, years ago, and was fully repaired | Must still be disclosed | The disclosure form asks whether there has EVER been evidence of water intrusion, not whether a problem currently exists. A completed repair does not remove the history. |
| An insurance claim for water damage was filed and paid | Must still be disclosed | A settled claim is not a substitute for disclosure. The claim history itself is exactly the kind of evidence the form is asking about. |
| The home is being sold "as-is" | Disclosure duty is unaffected | An as-is clause governs who pays for repairs after closing. It does not waive the seller's statutory duty to disclose known defects before the buyer signs. |
| The basement floods every spring and the seller checks "no" | A disclosure violation | Known, recurring water intrusion checked as "no" on the form is the exact conduct the Seller Disclosure Act exists to prevent, regardless of how the purchase contract is worded. |
| A sump pump or water heater failure caused past water damage | Must be disclosed | The disclosure question covers any source of past water intrusion, not only storm or flood water — a failed appliance counts. |
This is general information about Michigan disclosure requirements, not legal advice for a specific transaction. Confirm details with a real estate attorney or your agent.
A disclosure form only reports what the seller reports. These are the independent checks worth doing regardless of what the form says.
Read the disclosure form for what it does NOT say
A disclosure form only reports what the seller knows and chooses to report. A "no" answer is not proof nothing happened — it is worth an independent inspection either way.
Look for the tells in an unfinished basement
Efflorescence (white mineral staining) on block walls, a discolored ring on a wall or floor, a musty smell, or newer drywall/paint in only one section of an otherwise original basement.
Ask directly about insurance claims history
A seller must disclose known water intrusion, but a direct question about past claims puts the answer in writing and on the record.
Check the sump pump and its discharge line
A sump pit with rust staining, a battery backup that looks recently added, or a discharge line that empties right next to the foundation are all signs of a house that has needed help staying dry.
Get a professional moisture reading before closing if anything looks off
A moisture meter reads what a coat of paint cannot hide. This is a low-cost step relative to what a real, undisclosed water problem costs after closing.
Disclosure is a legal duty, not a negotiating decision. What actually protects a seller is doing it right and documenting the fix.
Disclose past water intrusion, even if it was repaired
Under the Seller Disclosure Act, this is a legal duty, not a judgment call about how relevant the buyer will find it.
Fix the actual source before listing, not just the symptom
A repainted basement wall over an unaddressed grading or sump problem is the fastest way to a post-closing dispute or a failed inspection.
Keep the paperwork
A written, dated restoration record, from a licensed contractor, showing what was done and to what standard, is worth more at the negotiating table than a verbal assurance the problem is solved.
Time the fix before the market, not during it
A remediation scheduled after a buyer's inspection flags a problem costs leverage in the negotiation that a resolved-and-documented issue never loses.
Two different jobs, two different calls
Buying or selling a house and fixing water damage are two separate, licensed functions, and conflating them is how both sides of a transaction end up frustrated. Here is the honest breakdown.

That is what Prime Restoration does — a free assessment before you list, or an evaluation of what a buyer’s inspection found, with written documentation either way.
Yes. The Michigan Seller Disclosure Act requires sellers to disclose any evidence of water intrusion in a basement or crawl space, past or present. A completed repair does not remove the history, and a seller who experienced basement flooding and made repairs still has an obligation to disclose what happened. This is a common point of confusion, and it is also a common source of post-closing disputes when it is skipped.
Yes. An as-is clause in a purchase agreement addresses who pays for repairs after closing — it does not waive the statutory duty to disclose known defects before the buyer signs. A seller who knows the basement floods every spring and checks "no" on the disclosure form is exposed to a disclosure claim regardless of how the contract is worded.
Yes. If a claim was filed for basement flooding, that history must be disclosed even if the claim was paid and the repair is complete. The claim itself is evidence of past water intrusion, which is exactly what the disclosure form asks about.
A disclosure form only reports what the seller reports. Independent of the form, look for efflorescence (white mineral staining) on basement walls, a discolored ring on a wall or floor, a musty smell, newer paint or drywall in only one section of an otherwise original basement, or a sump pit with rust staining. None of these prove a problem on their own, but they are reasons to ask for a professional moisture reading before closing.
Ask for the disclosure history and any insurance claim record directly, and consider a professional assessment before closing — a free moisture inspection can tell you whether the issue was actually resolved or just cosmetically covered. This is also the point to loop in a real estate agent who can renegotiate price or request repairs based on what the assessment finds.
A restoration contractor handles the water damage repair and remediation itself: extraction, drying, mold remediation if needed, and reconstruction, with written documentation of what was done. That documentation is what protects you at the negotiating table later. The real estate side — pricing, listing, marketing and negotiating the sale — is a separate, licensed function.
For the real estate transaction itself — listing, buying, pricing, negotiating — Real Estate Market Center in Troy is a team we know and recommend, with over 20 years of local experience and more than $100 million in closed sales across Troy, Rochester Hills, Birmingham, Bloomfield Hills, West Bloomfield, Sterling Heights and Warren. For the restoration side — assessing or repairing actual water, storm or mold damage before you list, or evaluating what you found during a home inspection — that is what we do.
