Is it urgent? Mold in a Plano home: call now or later

• Call now: mold after a sewer backup or flooding, a patch 25 contiguous square feet or larger (Texas's license line), mold inside walls or ducts, or anyone at home with asthma or a weakened immune system.
• This week: a musty smell with no visible source, a stain that grows, or mold back after cleaning.
• Can wait: a small spot on bathroom caulk or a window frame you can clean and keep dry.

The CDC lists a stuffy nose, sore throat, coughing or wheezing, burning eyes and skin rash among the effects of damp, moldy spaces, and says people with asthma or mold allergies may react severely.

Texas mold license rules for a Plano job

Texas licenses mold assessors and mold remediators through TDLR and keeps the two jobs apart. 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."

• Under 25 contiguous square feet: TDLR says visible mold below that size can be cleaned by people who are not licensed, so many small Plano jobs are done by the owner or a handyman.
• 25 contiguous square feet or more: a licensed remediator files a $25 notice with TDLR for the project; in an emergency, where waiting would let water damage spread the mold, the notice is due by the next working day.
• Apartments: in residential properties with 10 or more units, 25 contiguous square feet or more must be handled by a licensed remediator.
• Check before you book: TDLR's License Search looks up any assessor or remediator by name, number, city or ZIP.
• Your choice of company: the Texas Attorney General says your insurer cannot require you to use a specific mold company.

Mold in a Plano apartment: renters and city inspections

Plano has a lot of renters. The Census Bureau's 2020 to 2024 survey counts 48,422 renter households among 112,438 occupied homes, 43.1%. For apartment residents, the city runs a Multi-Family Rental Registration and Inspection Program, which Plano says exists to safeguard the life, health, safety, welfare and property of people living in multifamily communities, and to enforce minimum building standards and property maintenance codes.

Report the leak and the mold to the property manager in writing, with dated photos, and keep a copy. In a complex of 10 or more units, a patch of 25 contiguous square feet or more is a job for a TDLR-licensed remediator.

Why Plano homes get mold

NOAA's normals for its station in neighboring Richardson, just south of Plano, show 41.91 inches of rain a year and 57.1 days with 0.10 inch or more. Storm rain finds its way in through roofs and windows, but most Plano mold starts with plumbing. The Census Bureau puts the city's median year built at 1993, so many houses are on their second water heater with original supply lines, toilet seals and vanity drains, and a slow drip inside a cabinet can feed mold for months before anyone smells it.

The EPA says wet materials dried within 24 to 48 hours usually will not grow mold, so the drying after a leak matters more than any cleaner. The mold growth timer shows the window. If the leak is still active, start with water damage restoration in Plano; a supply line under the slab is a slab leak job.

How much does mold removal cost in Plano?

No Plano price is published, so the table shows three national guides side by side. HomeAdvisor's June 2026 average is $2,368, with most jobs from $1,223 to $3,757 and $10 to $25 per square foot. This Old House's March 2026 average is $2,300. Fixr's August 2025 average is higher, $3,500, with most jobs between $1,500 and $9,000. HomeAdvisor's national figures put a bathroom at $500 to $1,000 and an attic at $1,000 to $4,000.

In Texas the testing and the cleanup come from different companies, so expect two bills on a larger job. An inspection runs $300 to $650 in HomeGuide's figures, about $450 on average, and HomeAdvisor's testing with lab analysis runs $450 to $800. The EPA says sampling is usually unnecessary when mold is visible. More on when a mold inspection is worth it.

Does homeowners insurance cover mold in Plano?

The Texas Department of Insurance says most homeowner policies cover sudden and accidental water damage, such as a burst pipe, but not gradual leaks or seepage, and that includes the mold that follows. It also says mold from a flood needs a separate flood policy. So the date the leak started matters: photograph the mold and the source before anything is removed, call your insurer before the work starts, and do not sign anything that hands the claim to the contractor. TDI Bulletin B-0007-25 says a Texas contractor may not waive or rebate your deductible.

Questions to ask a Plano mold company

1. What is your TDLR license number, and is the assessor who wrote the protocol a different company?
2. Is this patch 25 contiguous square feet or more, and will you file the TDLR notice?
3. What is the moisture source, and who fixes it before you start?
4. How will you contain the area so spores do not spread?
5. Who does the post-remediation check, and what does it measure?

Calls go to an independent company that serves your area and takes this kind of job; hours vary (how calls work). Ask the company for proof of insurance, and for a license number wherever your state licenses the work.

Do this now: mold in a Plano home

1. Stop the water. Close the valve at the fixture or the main shutoff.
2. Keep sensitive people out of the room.
3. Leave the AC and furnace off if you suspect the system itself is moldy, the EPA says.
4. Measure the patch. At 25 contiguous square feet or more, Texas requires a TDLR-licensed remediator.
5. Photograph the mold and the leak, then call your insurer or write to your property manager.
6. Sign nothing that hands over the claim.
