Mold Inspection Before Buying a House in Texas

Only by sight, and even that isn't required.

Texas real estate inspectors are licensed by the Texas Real Estate Commission (TREC) and follow its Standards of Practice. Those standards cover a visual, non-invasive look at the general condition of a one- to four-family home. Under 22 TAC § 535.227, the inspector is not required to determine the presence, absence, or risk of mold, mildew, or any fungal presence or activity. The standards also don't require environmental testing.

What a home inspection does give you on mold is clues: roof leaks, plumbing leaks, stained ceilings, poor drainage, condensation, damp crawl spaces. Those are the conditions that grow mold.

Can a home inspector do a mold inspection in Texas?

Only if they also hold a TDLR mold license. TDLR's FAQ is clear:

• A real estate inspector does not need a mold license to visually observe and note the presence of mold.
• But collecting air or visible spore samples is mold assessment, so the inspector must be licensed as a mold assessment technician or consultant.

So if your home inspector offers "mold testing," ask for their TDLR mold license number and check it with our license check tool. There's no exemption for home inspectors in the Texas mold licensing law; the exemptions in § 1958.102 cover owners, small jobs, supervised employees and builders, not inspectors.

Home inspection vs mold inspection in Texas

Not automatically. The CDC does not recommend mold testing, and TDLR says it's not necessary to identify the species of mold growing in a residence. For most buyers, a careful home inspection is the first step.

A separate mold inspection for a home purchase makes sense when the home inspection or your own visit turns up warning signs:

• Visible mold or suspicious staining, especially in more than one spot
• A musty smell you can't trace. The EPA says you may suspect hidden mold if a building smells moldy, but you cannot see the source
• Signs of past leaks: ceiling stains, warped floors, new paint on one patch of wall
• A flood history. Hurricane Harvey alone flooded an estimated nearly 136,000 structures in Harris County
• A vacant home where the AC was off in summer
• Someone in your household with asthma, mold allergies or a weakened immune system. The CDC notes people with asthma or mold allergies may have severe reactions

What a licensed mold inspection includes

A licensed assessor looks for the location and extent of mold and its moisture source, and may take samples. Sampling isn't always needed. The EPA says that in most cases, if visible mold growth is present, sampling is unnecessary. Samples help most when the question is whether there's hidden growth.

If samples are taken, the assessor must use nationally accepted methods and a lab licensed under §78.62. Keep expectations realistic: there are no national or state standards for a "safe" level of mold, so results tell you whether there's a problem worth fixing, not whether the house is "safe." Our ERMI vs air sampling guide explains the test types.

Typical mold inspection costs (national figures; Texas-specific data not available)

Cost guides vary, so get a written quote. Our mold testing cost guide goes deeper.

TREC's promulgated contract forms include a termination option, which the Texas Real Estate Research Center calls an integral part of the contract for both the buyer and the seller. It explains that during the option period the buyer can terminate the contract for any reason or no reason at all, and that the option period exists so the buyer can do due diligence on the property, including specialty inspections.

The deadline is strict: termination notice must be given on or before 5 p.m. local time where the property is located on the last day of the option period. You can still inspect without an option period, but the article notes you can't then terminate and get your earnest money back over what you find.

A practical sequence:

1. Schedule the general home inspection in the first days of the option period.
2. If it flags moisture or mold, call a licensed mold testing company right away.
3. Leave room for lab results if samples are taken. Lab turnaround varies by lab and method, so ask when you book.
4. Decide before the option deadline: walk away, negotiate a repair or credit, or proceed.

Certificates of Mold Damage Remediation (5 years)

This is the most useful Texas-specific rule for buyers. When a licensed mold remediation project ends, the owner gets a Certificate of Mold Damage Remediation. Under Texas Occupations Code § 1958.154, if a property owner sells property, the property owner shall provide to the buyer a copy of each certificate issued for the property during the five years preceding the date the property owner sells the property. TDLR's rule repeats the duty in 16 TAC § 78.150.

Ask for these in writing early. A certificate tells you a licensed project happened, where, and that a licensed consultant certified clearance. TDLR notes that a certificate documenting the cause was fixed prevents an insurer from making an underwriting decision based on previous mold damage, which may matter when you shop for homeowners insurance.

No certificate doesn't prove no mold. Owners of homes can legally do their own mold work: Texas law exempts owners of a residential property owned by that person with fewer than 10 dwelling units. That work produces no certificate.

The seller's disclosure notice

Texas Property Code § 5.008 requires most sellers of a home with not more than one dwelling unit to give the buyer a written seller's disclosure notice. It's due on or before the contract becomes binding. If the seller delivers it late, the buyer may terminate within seven days after receiving the notice. Some sales, such as foreclosures, are exempt.

The notice doesn't have a separate "mold" checkbox in the statutory form we reviewed. It does ask about conditions closely tied to mold, including Water Damage Not Due to a Flood Event, Termite or Wood Rot Damage Needing Repair, and previous water penetration into a structure on the property due to a natural flood event. It's a disclosure of what the seller knows, and the form itself says it is not a substitute for any inspections.

Read the water and flood answers closely. A "yes" to past water damage is a good reason to book a mold inspection.

Mold in a house you're buying is usually a negotiation, not a deal-breaker. Bob Vila notes that buyers can use mold findings to negotiate the price.

Your options:

• Ask the seller to remediate using licensed companies, with a passed clearance report and a certificate before closing.
• Ask for a price reduction or credit and handle it yourself after closing. Get a remediation estimate first; see mold remediation cost.
• Walk away during the option period.

If the seller remediates, make sure the testing company and the removal company are different. Texas law says a license holder may not perform both mold assessment and mold remediation on the same project. Ask for the passed clearance report and the certificate, which is due not later than ten calendar days after the project stop-date.
