Top Mold Remediation Companies In Houston For 2027

Houston’s heat and humidity make mold a constant risk, and any leak, flood or AC condensate problem can trigger growth within a day or two. Texas regulates mold work: the Texas Department of Licensing and Regulation (TDLR) licenses mold assessors and remediators, and for larger jobs the assessor and remediator must be separate companies.

The companies below hold Texas mold remediation credentials and serve the Houston metro. Each entry notes its strengths.

How To Choose A Mold Remediation Company In Houston

Are they TDLR licensed?

Texas requires licensed mold remediators for most jobs, and for projects over 25 contiguous square feet an independent licensed assessor must write the protocol. Ask for both license numbers.

Will they fix the moisture source?

Removing mold without fixing the leak or humidity problem means it will return. Ask how they will find and address the source.

How do they contain the work area?

Proper remediation uses plastic containment, negative air pressure and HEPA filtration to keep spores from spreading.

Is clearance testing included?

After remediation, an assessor should confirm the area passes before walls are closed. Ask who performs it.

Conclusion

RestoPros, One Plus and DryMedic are strong local choices that pair remediation with repairs. Rainbow, PuroClean and United Water add network depth, and ATI handles large commercial jobs.

In Texas, always confirm TDLR licensing and keep the assessor independent from the remediator on bigger jobs.
