Mold Removal & Remediation in Humble, TX

Signs to look for

• Spotting or a waterline on walls in rooms that took floodwater
• A damp smell from cabinets under the kitchen or bathroom sink
• Growth on the underside of window sills where condensation collects
• Ceiling stains below the attic air handler
• Mildewed boxes or clothes in a closet against an outside wall

What makes Humble homes vulnerable

Humble, about 17 miles northeast of downtown Houston, became an oil boomtown after the 1904 strike and was home to Humble Oil and Refining. It sits in the Lake Houston area, where the San Jacinto River and Cypress Creek both breached their banks during Harvey. The river covered sections of Interstate 69 and crested above 68 feet, rescues took place in the Northshire subdivision, and the city manager later said 340 homes in Humble were affected, many without flood insurance. When a house stays wet that long, growth inside walls is likely even where the paint looks fine. Outside of floods, the heat and humidity keep AC systems running and condensate lines working hard for much of the year.

Cost considerations

Angi's Houston cost data reports an average of $2,016 for mold removal. A single bathroom will price very differently from a flooded first floor. The main factors are area, material removal, containment, access, and whether the HVAC system is involved; HomeGuide's 2026 national range for an HVAC system or ducts is $2,000 to $10,000. The assessor's protocol and clearance visit are billed separately. Rebuilding is handled through the City of Humble Building Department at City Hall on West Higgins Street, which requires plan submission for interior remodels and floodplain work.

What happens when you call

An independent local company answers and asks about the water source, the size of the growth and your schedule. It should walk you through the Texas steps: protocol from the assessor, work plan from the remediator, removal, a clearance check by the same assessor, and a Certificate of Mold Damage Remediation delivered within 10 days of completion. If the job is 25 contiguous square feet or larger, the remediator also files a notice with TDLR at least five days before starting, so build that lead time into your plans. Keep every document together; if you sell within five years, the buyer is entitled to copies of the certificate.
