Frequently asked questions
How do I check a mold pro's licence in Katy?
Look the name up in the TDLR records and ask for the licence number in writing. Each listing here shows the licence numbers from the agency's records. The Katy hiring guide lists questions to ask.
How much does mold inspection cost in Katy?
National HomeAdvisor figures put mold inspection or assessment at $303–$1,075 (average about $689) and mold remediation at $1,223–$3,757 (average about $2,368). There are no Katy-specific prices, so get written quotes. See the cost guide and estimate tool.
Can the same company test and remove mold in Katy?
No. In Texas, the company that assesses your mold can't also remove it on the same job, so get assessment and remediation quotes from different licensed firms.
