Mold in a Richmond-Area Home Before You Buy: What an Inspector Can Tell You, What a Separate Assessment Adds and What Virginia Law Says

Published October 19, 2026

Does a home inspection cover mold? Not as a promise. The residential property disclosure statement that Virginia’s Real Estate Board posts lists a home inspection and a mold assessment as two separate steps a buyer may choose to take, and the owner makes no representations about the condition of the home. The federal EPA also says it sets no limits for mold in indoor air, so no lab number can tell you a house “passes.” What a buyer can do is read the moisture clues, decide whether to order an assessment before the contract deadline and know when a patch of mold is a cleaning job and when it is a contractor’s.

This guide covers homes across the city of Richmond, Henrico County and Chesterfield County. It is general information, not legal or medical advice. For a specific house, talk to your inspector, a Virginia real estate attorney and, for health questions, a health professional.

What the Virginia disclosure statement tells a buyer to do about mold

Virginia is a buyer-beware state. Section 55.1-703 of the Code of Virginia says the disclosure statement must tell the buyer that the owner makes no representations or warranties about the condition of the property. It then advises purchasers to use whatever due diligence they judge necessary, including a home inspection, “a mold assessment conducted by a business that follows the guidelines provided by the U.S. Environmental Protection Agency,” and a residential building energy analysis. The statute adds that this should happen under the terms of your purchase contract, and in any event before settlement.

Read that sentence as a to-do list with a deadline. The inspection and the mold assessment are named separately, which tells you not to assume one covers the other. Before you sign, check your contract’s inspection window and ask your inspector in writing what the report will and will not say about mold. If you want an assessment, book it early enough to fit inside that window. Our guide to what a Richmond home inspector will not cover lists other add-ons that run on the same clock.

Why a lab number does not tell you a house passes

Buyers often assume a mold test works like a radon test, with a pass line. It does not. The EPA’s guide to mold, moisture and your home says no EPA or other federal limits have been set for mold or mold spores, so sampling cannot be used to check a building against a federal standard. The same guide says that in most cases, if visible mold growth is present, sampling is unnecessary. It says surface sampling may help show whether an area was cleaned adequately, and that sampling should be done by professionals with specific experience in designing sampling plans and interpreting results.

The EPA also notes it is impossible to get rid of all mold and mold spores indoors, because some spores are always floating in air and house dust. What matters is whether there is moisture feeding growth. So the useful questions in a purchase are about water: where it came from, whether it is fixed and what it touched. A clean-looking wall that sat wet behind a refrigerator tells you more than a spore count taken in the living room.

Reading the moisture clues on a showing and at the inspection

The EPA’s central rule is that moisture control is mold control. It says water-damaged areas and items should be dried within 24 to 48 hours, and that if wet or damp materials are dried in that window, mold usually will not grow. That gives you a way to read a house. Ask the seller what leaked, when and how fast it was dried. The state’s disclosure statement is the place to look for what the owner chose to report, but because the owner makes no representations, your own eyes matter too.

The EPA’s prevention list doubles as a checklist for a walk-through. It points to gutters that are cleaned and repaired, ground that slopes away from the foundation, clean air conditioner drip pans with unobstructed drain lines, and condensation on windows, walls or pipes as a sign of high humidity. It suggests keeping indoor relative humidity below 60 percent and ideally between 30 and 50 percent, and says a humidity meter is a small, inexpensive tool. Bring one to a second showing if a basement or crawl space is on your list.

Hidden mold is harder. The EPA says you may suspect it if a building smells moldy but you cannot see the source, or if you know there was water damage and occupants report health problems. It lists places mold hides, including the back of drywall, wallpaper or paneling, the underside of carpet and pads, areas inside walls around leaking pipes and the surface of walls behind furniture. If the house has a crawl space, our guide to the wood-destroying insect report and why crawl spaces fail covers the moisture conditions that inspectors flag there, and the guide to old plumbing in Richmond-area homes covers the leak sources behind many wall stains. A roof near the end of its life is another water path worth ruling out.

Ten square feet, and who does the cleanup

If an inspector or your own walk-through finds mold, the EPA draws a practical line. For a moldy area smaller than about 10 square feet, roughly a 3-foot by 3-foot patch, it says that in most cases you can handle the job yourself, using its cleanup guidelines. Larger areas, heavy water damage, suspected contamination of the heating and cooling system or sewage-contaminated water call for more. The EPA says to consult its remediation guidance for bigger jobs, to avoid running an HVAC system you know or suspect is contaminated and to bring in an experienced professional when the water was sewage or other contaminated water.

The EPA also says two things that matter in a negotiation. If you clean up mold but do not fix the water problem, the mold will most likely return. And dead mold can still cause allergic reactions in some people, so it must be removed, not just killed. It does not recommend routine use of bleach or other biocides during cleanup, and warns never to mix chlorine bleach with cleaners that contain ammonia. In practice, that means a repair request should name the water source, not only the stain. Our guide to negotiating repairs after a home inspection explains the repair-credit-price options.

Choosing who assesses and who cleans

Do not assume a state license vouches for the person you hire. The Code of Virginia’s chapter on asbestos, lead and home inspection contractors still carries an article heading for mold inspectors and remediators, but the sections that sat under it were repealed by the General Assembly in 2012. The EPA’s advice for hiring is to choose a contractor with mold cleanup experience, check references and ask for work that follows EPA or other professional guidelines. The Virginia Department of Health says it cannot provide environmental testing or remediation for mold, and that concerned residents should consult an environmental specialist when needed.

Two questions are our own suggestion rather than a rule. Ask whether the company that assesses the home also sells the cleanup, and ask for the scope in writing, including how the company will decide that the job is finished. The EPA’s own test for finished is that the water problem is fully fixed, visible mold and moldy odors are gone, a revisit shortly after shows no signs of water damage or growth, and people can reoccupy the area without symptoms.
