Mold and Selling a York Home

What buyers and inspectors actually flag

They write up visible growth, wet carpet, a humidity gauge they brought with them, a crawl they refuse to finish crawling, and “possible microbial growth — evaluate.” That last phrase is an inspector staying in their lane. It is not a species ID, and it is not a quote. Your job is to answer it with a cause and a dry material, not with a scented candle at the open house.

Radon contingencies are familiar around Codorus and Spring Garden. Pair them with an honest moisture note if you have one. Our post-mitigation testing timeline and a mold repair timeline can run in parallel. They are not the same appointment.

Repairs that hold up in a negotiation

• Stop the leak or document that it was condensation and show humidity logs under 50%.
• Remove what cannot be cleaned. Keep disposal photos.
• Clean hard surfaces. Do not fog and leave.
• Skip new carpet and new drywall until the space has been dry through a rainy week.
• Write down what a buyer should maintain: empty the dehumidifier, keep the spout extended.

Disclosure

Pennsylvania seller disclosure asks about water and, depending on the form year, dampness and repairs. Hiding a mold project is how small money becomes a lawsuit story. Say what you found, what you removed, and what you did not open. “Unknown behind the finished wall” is allowed. “Never had a drop of water” is not, if you tore out a wall in May.

If you are the buyer

Ask to see the basement after the dehumidifier has been off for a day, not ten minutes after someone ran out and emptied it. Take your own gauge. Look in the crawl even if you do not like crawls — or pay someone who does. Testing before you buy is sometimes right and often unnecessary if the growth is already on the joist in front of you.

Questions people also ask

These pages are homeowner education from Radon Mitigation of York, written by Dave Kessler. They are not a medical diagnosis, a species identification, or an insurance determination. Color does not tell you which mold you have. If someone in the house is sick, talk to a physician. EPA's homeowner guidance treats roughly 10 square feet as the line where many people stop DIY cleanup and call a remediation crew — sooner if sewage, HVAC, or anyone immunocompromised is involved. We are a radon and basement crew. When we are already under a York house we will tell you what we see and what we would do in our own place. We do not pretend a radon fan is a mold remedy.
