In Bellaire, commercial mold often follows Brays Bayou flooding or a hidden roof leak, and any project of 25 contiguous square feet or more must be handled by a company holding a TDLR mold remediation license, working from a separate consultant's protocol. Flood-related repairs in the city also need a permit before work starts. Call the number on this page to be connected with a local mold remediation company in Bellaire.

Bellaire at a glance
Bellaire, about 6 miles from downtown Houston, calls itself the City of Homes, and most of its land is residential. Its commercial buildings line corridors such as Bellaire Boulevard, Bissonnet, Chimney Rock and the 610 Loop. Much of the city lies in the 100-year floodplain, and Brays Bayou overflows into it. Tropical Storm Allison flooded more than 1,400 structures in Bellaire, the 2015 Memorial Day storm more than 200, and Hurricane Harvey more than 2,000.
What to do now
- Find and stop the water. A roof drain, a failed condensate line or bayou water all need a different fix, and mold comes back if the source stays.
- Dry what you can within 24 to 48 hours, as EPA advises. Do not run an air handler you suspect is contaminated.
- Measure the visible growth. Under 25 contiguous square feet, the owner or tenant and their staff may clean it in a non-residential building. At or above that size, a TDLR remediation license holder must do the work.
- Hire a mold assessment consultant to write the protocol. Texas law keeps that firm separate from the remediation company.
- Before any flood-related repairs, get the free permit from City of Bellaire Development Services. The city requires it before work begins and warns owners about dishonest contractors after floods.
- Keep the clearance report, photos and Certificate of Mold Damage Remediation with the building records.

What you see and what usually causes it
| What you see | Likely cause |
|---|---|
| Stained drop-ceiling tiles in a line | Roof leak or a dripping duct above the grid |
| Wicking stains at the base of drywall | Floodwater or a slab-level plumbing leak |
| Spotting around supply vents | Cold air meeting humid air; possible duct contamination |
| Odor in a back office with no visible growth | Growth inside a wall cavity or behind cabinets |
Cost factors
Commercial work is priced by area, access and disruption. Tall ceilings, merchandise or files that must be moved, after-hours scheduling and HVAC cleaning all add to the total. HomeGuide's 2026 national figures put remediation at $15 to $30 per square foot. You will also pay the consultant separately for the protocol and the post-remediation assessment. Floodplain rules matter too: in Bellaire, a building found substantially damaged or improved (50 percent of pre-damage market value) must meet current floodplain standards, which can change the rebuild budget after a major flood.
