Dallas FAQ

Mold Testing in Dallas: common questions

How much does mold testing cost in Dallas?

It depends mostly on how much material is affected and how it has to be handled. We don't publish a price for Dallas without data to back it; our mold testing cost guide covers Texas price ranges and what changes them. Get written quotes from at least two licensed companies.

Can the same company test for mold and remove it?

Not on the same project. Texas Occupations Code §1958.155 bars a license holder from doing both mold assessment and mold remediation on one project, and bars anyone from owning a stake in both companies on it. A company can hold both licenses and do each on different jobs. Find a licensed mold removal company in Dallas.

What happens after mold testing?

If the assessor finds mold that needs removing, they write a remediation protocol. You hire a different licensed removal company to follow it, then the assessor comes back for a clearance check. After it passes, you should receive a Certificate of Mold Damage Remediation within ten days.

How do I check a mold testing company's license?

Search the company name or license number in our Texas mold license check, or on TDLR's own license search. A mold testing company needs a mold assessment company license; its number starts with ACO.

How many licensed mold testing companies are in Dallas?

12 licensed mold testing companies have a Dallas address, and 60 are based in the Dallas-Fort Worth area, according to TDLR records as of Oct 28, 2026.
