Mold Inspection & Remediation in Dallas, TX

Dallas averages about 38 inches of precipitation a year under NOAA's 1991–2020 normals, and October and May are the wettest months. Much of it falls in spring and fall thunderstorms that can drop several inches in an evening, and roofs damaged by wind or hail let that water into attics and walls.

Flash floods can arrive with little warning. In August 2022, after weeks of drought, the official gauge at DFW Airport recorded 9.19 inches of rain in 24 hours, the second-highest 24-hour total on record there, and parts of southeast Dallas measured more than 15 inches. Water seeped into homes and businesses. Drywall, carpet, and cabinets at floor level soak up water within hours, and the EPA warns that mold becomes likely if they are not dried within 24 to 48 hours.

The ground adds its own risk. Much of Dallas is built on expansive clay soils that swell when wet and shrink during drought, and as foundations move, supply and drain lines under slabs and inside walls can crack. A slow leak may go unnoticed until a baseboard darkens or a floor feels soft. Hard freezes are the other hazard: the February 2021 winter storm burst pipes in homes across North Texas.

Dallas homeowners report paying about $300 to $1,075 for a mold inspection; where you land depends on square footage, how many samples are pulled, and whether a written protocol is part of the visit. Removal prices on this page come from North Texas contractor price guides published in 2025 and 2026, and the clearance figure from a 2026 Dallas cost guide. Expect three separate bills on a licensed Texas project: the consultant's assessment, the contractor's removal, and the final clearance. Flood jobs that run through several rooms also carry drying and rebuild costs. Our remediation cost guide breaks down each line.

In Dallas, as everywhere in Texas, mold work is licensed by the Texas Department of Licensing and Regulation. Two different licenses matter to you: a mold assessment consultant inspects, samples, and writes the protocol, and a mold remediation contractor does the removal. State rules require a licensed contractor once the growth reaches 25 contiguous square feet, and a single license holder cannot both assess and remediate the same project. Since September 1, 2025, the employees on the crew must also carry their own TDLR license or registration.

Before anyone cuts open a wall in a Lakewood bungalow or crawls under an older pier-and-beam house in Oak Cliff, look the company up at tdlr.texas.gov and confirm it carries the $1 million in general liability coverage the state requires. You should be handed the Consumer Mold Information Sheet before work starts, and the Certificate of Mold Damage Remediation no later than 10 days after the job is finished. Cleaning mold in a house you own yourself needs no license at all.

The August 2022 storm is the clearest example of where Dallas homeowners policies stop. Rising water from that kind of flash flood is excluded from standard homeowners coverage; it is a flood-insurance claim, and a brand-new National Flood Insurance Program policy usually does not start for 30 days, so buying one after a forecast is too late. Water that comes from inside the house is different. The Texas Department of Insurance says most policies cover sudden and accidental damage, such as a supply line that bursts in a freeze, along with mold on the things it soaked.

Slow leaks are where claims get denied. A drain line seeping under the slab for months as the clay shifts is usually treated as gradual damage, and many Texas policies cap or exclude mold remediation on top of that. Report water as soon as you see it, photograph before anything is torn out, and file the Certificate of Mold Damage Remediation with your records; once it shows the cause was fixed, your insurer may not base an underwriting decision on that past mold.
