Mold in Walls & Drywall in Crosby, TX

How do I know the mold is inside the wall and not just on it?

Surface mildew in a bathroom tends to wipe off and sits on top of sound paint. Growth inside the cavity gives different clues: a smell that is strongest at one spot, drywall that feels soft or cool, paint that bubbles from behind, and baseboards that swell or pull away from a slab floor. A stain that keeps returning in the same place after cleaning is another sign the source is behind the drywall. A mold assessment consultant can confirm it with a moisture meter or a thermal camera, and sometimes a small inspection hole, before larger sections are opened.

Can I just cut out the bad section myself?

Texas allows homeowners to clean mold in their own home, and EPA says an area under about 10 square feet is usually manageable once the water problem is fixed. Wall cavities are harder to judge. The back of the drywall and the insulation are often worse than the front, and cutting into moldy board without plastic sheeting and negative air can spread dust through the house. People with asthma or weakened immune systems should stay away from the work. If you hire someone, Texas requires TDLR licenses, and the company that writes the protocol cannot also do the removal on that project.

What should I expect to pay, and is there paperwork?

Angi's Houston cost data reports mold removal averaging $2,016, with most jobs between $863 and $3,329. Plan on a second, smaller bill for the assessment consultant, plus drywall, paint and trim if the remediation quote leaves them out. When the job passes the post-remediation assessment, you receive a Certificate of Mold Damage Remediation. Keep it with your house records, because a seller must give buyers copies of any issued in the previous five years.

A note for Crosby homeowners

Crosby is a small unincorporated community in east Harris County, about 25 miles from downtown Houston, that grew from an 1820s settlement into a railroad shipping point for lumber and farm goods. Heavy rain is the local risk to watch: in an October 2015 storm, the Harris County Flood Control District measured about 13 inches, and businesses at a Crosby shopping center had more than four inches of water on their floors. Once the mold work is done, rebuilding walls is permitted through the Harris County Office of the County Engineer's Residential Group, not a city office.
