Dallas Mold Removal: $1,366 to $3,480 + Texas Rules (2026)

The Dallas rows are Angi's Dallas guide, updated October 2025. The national rows are there for comparison; the notification fee is a Texas rule.

Do this now: mold in a Dallas home

1. Find and stop the water first. The EPA says wet materials dried within 24 to 48 hours usually will not grow mold, so a slab leak, a roof leak or a sweating AC line has to be fixed before any cleanup holds.
2. Keep anyone with asthma or a mold allergy out of the room; the CDC says they may have severe reactions.
3. Do not run the air conditioning if you think the system or the ducts have mold in them, the EPA says.
4. Photograph the growth and the leak, then call your insurer if the water came from a sudden event like a burst pipe.
5. Measure the patch. Under 25 contiguous square feet, Texas lets anyone clean it; under about 10 square feet, the EPA says a homeowner usually can. Bigger than that, call the water damage line.
6. Do not sign any contract that hands your insurance claim to a contractor.

Is it urgent? When Dallas mold calls for a company this week

Mold is urgent when it follows sewage or flooding, when it covers more than 25 contiguous square feet (the Texas licensing line) or more than about 10 square feet (the EPA's homeowner line), when it is inside the HVAC system, or when someone in the house is coughing, wheezing or breaking out in a rash, the symptoms the CDC lists. A thumb-sized spot on bathroom caulk can wait for a scheduled visit. Angi prices a Dallas bathroom at $500 to $1,500 and an HVAC system at $1,900 to $6,500, so the location drives the bill more than the color of the mold. Water still inside? Start with the water damage restoration guide and a plumber in Dallas for the leak.

Texas mold license rules that apply in Dallas

Texas licenses mold assessors and mold remediators through TDLR, and it splits the job in two. A licensed Mold Assessment Consultant writes the protocol and does the post-remediation check; a licensed remediator does the removal; and TDLR's FAQ says a licensee is "not allowed to conduct both mold assessment and mold remediation activities on the same project." Visible mold under 25 contiguous square feet can be cleaned up by people who are not licensed, which is why many small Dallas jobs are done by the homeowner or a handyman. Remediation of 25 contiguous square feet or more needs a $25 notification to TDLR, and in an emergency, where waiting would let water damage spread the mold, the notice is due by the next working day.

• In rental buildings with 10 or more units, 25 contiguous square feet or more must be handled by a licensed remediator.
• Look up any assessor or remediator on the TDLR License Search by name, number, city or ZIP before you book.
• Complaints about a licensed mold company go to TDLR, within two years of the event.
• The Texas Attorney General says your insurer cannot require you to use a specific mold company.

Dallas code treats mold as a plumbing problem

Dallas Code Compliance's Chapter 27 Minimum Property Standards manual puts mold under its plumbing standards: the commentary to Section 27-11(f)(1) reads "Prevent mold to surface from moisture" and carries an "Examples of Mold" heading. In practice that means a Dallas inspector looks for the leak, not the stain, so a renter reporting mold should name the water source (a dripping valve, a roof leak, a wet wall) when filing. Owners can also use the Dallas Water Utilities leak adjustment: one per 12 months, covering at most three months of excess use, recalculated at the lowest rate possible, with up to 60 days to process. It does not pay for plumbing repairs or mold work.

For an owner-occupant at or below 80% of area median income, the City's Emergency Home Rehabilitation grant pays up to $10,000 when the emergency happened within the four days before applying and poses an immediate life, health or safety concern; a burst pipe that soaked a bedroom fits that description better than slow mildew. Apply through the Housing Repair Programs page.

Where mold shows up in Dallas houses

Dallas's median home was built in 1981, and 283,779 of its 590,237 housing units, 48.1%, predate 1980, the Census Bureau's 2020 to 2024 survey shows. DFW Airport's normal year brings 37.01 inches of rain on 52.2 days with 0.10 inch or more, so the water that feeds mold here is more often a plumbing or roof leak than steady drizzle. Angi's Dallas guide says the same: hot, humid conditions after leaks or rain. Slab foundations on clay soil put supply lines under the floor, which is why a warm spot on the floor or a water bill jump is worth a leak detection visit before any mold cleanup.

Mold inspection in Dallas: when testing helps and when it does not

A mold inspection in Dallas runs $300 to $1,075, Angi's October 2025 Dallas figure; HomeGuide's national range is $300 to $650. The EPA says that if you can see mold, sampling is usually unnecessary, and that no federal limit exists for mold or spores, so a lab number cannot tell you whether a home is safe. The CDC does not recommend mold testing. An inspection earns its fee when the growth is hidden: the EPA says to suspect hidden mold when a room smells musty but you cannot see the source, with the usual spots behind drywall, inside walls around pipes, inside ductwork and above ceiling tiles. In Texas the inspector is a licensed Mold Assessment Consultant, and by law a different company from the remediator, so an inspection fee buys an independent protocol and clearance check rather than a sales visit.

Questions for a Dallas mold remediation company

1. What caused the moisture, and who fixes the source before the cleanup starts?
2. How will you contain the area so spores do not spread through the house, and will you run the HVAC during the work?
3. Will you remove the materials or only clean and spray them, and what happens to insulation and drywall?
4. What is your TDLR license number, and is the assessor who wrote the protocol a different company from you?
5. Will you show moisture readings at the end, and who does the clearance check?
