Most mold inside Humble walls comes from water that sat in the cavity, such as river or creek flooding, a plumbing leak or an overflowing AC drain. After the source is fixed, the wet drywall and insulation are removed and the studs cleaned and dried. Call the number on this page to be connected with a local mold remediation company in Humble.

Signs to look for
- Paint that puffs out or cracks in a line along the bottom of a wall
- A stain that widens after rain or after weeks of heavy AC use
- Baseboards that are darker, swollen or loose at the corners
- An odor that is stronger with the closet door shut
- Drywall that dents easily under a thumb
Local conditions in Humble
Humble is a small city of about 16,800 in northeast Harris County, about 17 miles from downtown Houston, that grew as an oil boomtown after 1904. The San Jacinto River and Cypress Creek both breached their banks in Humble during Hurricane Harvey, flooding roads and homes; the river covered parts of Interstate 69 and crested above 68 feet, and rescues took place in the Northshire subdivision. The city manager later said 340 homes in the city were affected and many owners lacked flood insurance. Homes repaired quickly after a flood can hide damp framing or insulation that was never fully dried. Away from the river, the everyday sources are the same as across the region: humid air, attic air handlers and slow plumbing leaks.

What affects cost
Angi's Houston cost data reports mold removal averaging $2,016, mostly between $863 and $3,329. Cost climbs with the area of drywall removed, the number of rooms under containment, insulation and cabinet removal, and how hard the wall is to reach. In Texas you will also pay a mold assessment consultant separately, because the company that assesses a project cannot remediate it.
What happens when you call
You describe the wall and any water history and are connected with an independent company serving Humble. If the job is hired out, a consultant who holds a TDLR license inspects and gives you a written protocol at least one calendar day before work starts. A separate remediation company follows it, and the consultant does the post-remediation assessment before the wall is closed. Then you receive a Certificate of Mold Damage Remediation. The City of Humble Building Department at City Hall, 114 W. Higgins St., handles permits, and it requires plan submission for interior remodels and floodplain work, so ask before rebuilding.
