Sell a House With Mold — No Remediation Required

Where mold comes from in Pinellas houses

Florida humidity does most of the work. The EPA recommends keeping indoor humidity below 60 percent, ideally between 30 and 50. A closed-up block house in St. Petersburg with the air conditioning off in July runs well above that for weeks. Add a water source and mold follows. The sources we see most:

• Storm surge. Helene put 5 to 7 feet of water across the Pinellas coast on September 26, 2024, a record 6.31 feet above normal high tide at the St. Petersburg gauge. Drywall and insulation that stayed wet for days, not hours, grew mold whether the house was gutted later or not.
• Roof leaks. Milton tore shingles and decking off roofs across the county two weeks later. A tarp or a blue roof that is still up two years on has been letting water in every summer afternoon. See selling a house with a bad roof.
• AC failure in an empty house. The owner dies or moves into care, the power gets cut or the air handler quits, and nobody opens the door for six months. This is the most common mold call we get on inherited houses.
• Plumbing. Original galvanized supply lines and cast iron drains in 1950s and 60s houses leak slowly inside walls and under slabs, and the mold shows up long before the leak does.

The EPA notes that mold is often hidden on the back of drywall, behind wallpaper or paneling, and under carpet and pad. What you can see is rarely all of it.

What Florida law says you have to tell a buyer

Florida has no statute that singles out mold for disclosure. The duty comes from the Florida Supreme Court. In Johnson v. Davis, 480 So. 2d 625 (Fla. 1985), the court held that where the seller of a home knows of facts materially affecting the value of the property which are not readily observable and are not known to the buyer, the seller is under a duty to disclose them. Mold behind the walls, a past flood, a remediation that was never finished: all of that fits.

Two things sellers get wrong. First, an "as is" contract does not remove the duty. Florida courts have said there is no as-is exception to Johnson v. Davis. Second, once you have a mold report or a remediation quote in hand, you know, and from that point the only safe path is to hand it to the buyer. The rule has been applied to homes; whether it reaches a duplex or a commercial building is less settled. If you are unsure what you have to say, talk to a Florida attorney before you sign a contract.

With us, disclosure is simple. We want the report. We are going to open the walls anyway, and the more we know going in, the more accurate the offer is.

Assessors, remediators and the licensing rule

Florida regulates mold work under Fla. Stat. ch. 468, part XVI. The Department of Business and Professional Regulation licenses two trades: mold assessors, who sample and evaluate, and mold remediators, who remove. Under § 468.8411 the licensing definitions apply to mold growth or contaminated material of more than 10 square feet. The EPA draws the same line for do-it-yourself cleanup: under about 10 square feet, roughly a 3-by-3 patch, most people can handle it. A flooded living room is not that.

Section 468.8419 keeps the two trades apart. A licensed assessor may not remediate a house it assessed in the past 12 months, a remediator may not assess a house it remediated, and neither may pay or accept a referral fee from the other. An assessor also cannot take a job where the fee depends on the result. There is an exemption in § 468.841 for a homeowner working on their own property, but the moment you hire someone, the license rules apply.

A proper job therefore has four stages: an assessment with a written protocol, remediation by a second company, a clearance test, and then the rebuild of everything that was removed. That is weeks of scheduling and three or four separate invoices, which is why most sellers who get the first quote stop there.

Why the remediation quote scares buyers and lenders

The remediation quote is almost never the whole cost. It covers containment, removal and disposal. It does not cover the drywall, insulation, baseboard, cabinets and flooring that come out with the mold, and it does not cover the leak or the roof that caused it. A buyer who sees a remediation quote mentally doubles it, and they are often right to.

Buyers also do not trust that the mold is gone. A clearance letter covers the areas that were tested. The EPA's own guidance says mold hides behind drywall and under carpet, and every buyer has read that. So even a remediated house gets a price cut, a second inspection and a longer contingency period.

Lenders are worse. An appraiser who sees active mold or water damage that affects the soundness of the house has to make the appraisal subject to repairs, and the buyer's insurer sees the stains on the 4-point and declines. That turns a mold house into an uninsurable house, and the financed buyer is gone either way.

How we buy a house with mold

Mold is one of the conditions we buy most often, usually alongside the leak or the flood that caused it, and it does not change how a sale with us works.

1. One walkthrough, 15 to 30 minutes. If the smell is bad, we wear a respirator and you can wait outside. A relative, a neighbor or a lockbox works if you are out of state.
2. A written offer, typically within 24 hours. We price the demolition, the licensed assessment and remediation, the rebuild and the water source, and we show you each line against the renovated value. If the mold is small and dried out and listing would net you more, we say so on our compare page.
3. Closing in as little as 7 to 14 days when title is clean, or on your schedule. No fees, no commissions, and we pay the normal closing costs. Liens or a mortgage are paid from the price by the title company.
4. After closing we hire the licensed assessor and a separate licensed remediator, pull the permits for the rebuild and fix the leak. You do not clean, bleach, test or meet a contractor. Leave whatever contents you do not want.

If the house is an estate, we also pay for and handle the probate; an attorney represents the estate. Our probate guide explains how that works.
