Buying or selling a house with mold in Pennsylvania
The inspector found mold. What Pennsylvania disclosure law says, who usually pays, and how to keep the deal together.
Mold turns up in a lot of Gettysburg-area home inspections, particularly in older borough houses and in any house with a finished basement. It rarely kills a deal if both sides handle it sensibly.
Disclosure
Pennsylvania's Real Estate Seller Disclosure Law requires sellers to disclose known material defects, and the standard disclosure form asks directly about water intrusion and mold. A seller who knows about past or present mold and does not disclose it is exposed to a claim after closing. A seller who remediated it and kept the paperwork can disclose it with confidence.
For buyers
- Ask the inspector to find the water, not just the mold. The remediation quote depends on the source.
- Get a remediation quote before the inspection contingency expires. Most firms on this site will quote from photos and a call within a day or two.
- Decide what you are asking for. A price reduction equal to the quote, or the seller doing the work before closing with a clearance test. A reduction gives you control over who does the job; seller-done work is faster.
- Insist on a clearance test by an independent tester if the seller does the work.
For sellers
If you know about mold, deal with it before listing. A completed remediation with a written scope, invoice and an independent clearance report is a non-issue for most buyers. An undisclosed problem found by their inspector is a negotiation you will lose.
Who pays
There is no rule. In a buyer's market the seller usually pays; in a seller's market the buyer often absorbs small jobs. For anything over a few thousand dollars, a credit at closing is the usual compromise. Lenders do not normally require mold remediation unless the appraiser flags it as affecting habitability, which is uncommon.
Insurance after closing
A new homeowner's policy will not cover mold that existed before the policy started. If you buy a house with known mold, budget to fix it yourself. See the insurance guide.
