Bellaire homes near Brays Bayou have flooded more than once, so mold remediation here often deals with wet drywall, insulation and flooring left behind by high water. Under Texas law, one company assesses the mold and writes the plan, and a different company removes it. Call the number on this page to be connected with a local mold remediation company in Bellaire.
Bellaire at a glance
Bellaire is a small residential city about 6 miles from downtown Houston, surrounded by Houston and West University Place. Much of it lies in the 100-year floodplain of Brays Bayou. Tropical Storm Allison flooded more than 1,400 structures here, the 2015 Memorial Day storm more than 200, and Hurricane Harvey more than 2,000. Many original post-war houses have since been torn down and rebuilt, but nearly all of the buildings that flooded in Harvey were not built to the current elevation standard.
What to do now
- Stop the water and dry. Fix the leak or pull out wet materials, then run fans and dehumidifiers. EPA's window is 24 to 48 hours before mold should be assumed.
- Turn off the central air if it got wet. Running a contaminated system can push spores through the house.
- Photograph everything. Pictures taken before anything moves help with insurance and with the assessor's notes.
- Get an assessment. A mold assessment consultant who holds a TDLR license inspects and writes the protocol, which you receive at least one day before work.
- Hire a separate remediator. Texas forbids the assessor's company from doing the removal on that project.
- Pull the repair permit. Bellaire requires a permit, at no charge, for all flood-related repairs, issued by Development Services before work begins. The city also warns residents about dishonest contractors who appear after floods.
Signs and likely causes
| What you see | Likely cause |
|---|---|
| Tide line and stains low on walls | Floodwater from a Brays Bayou overflow or street ponding wicked up the drywall |
| Musty odor from supply registers | Condensation in ducts or a dirty air handler drain pan |
| Spots on a ceiling beside a bathroom | Weak exhaust fan or a slow plumbing leak above |
| Cupped or warped wood floor | Moisture under the boards from a leak or high water |
Cost factors
Angi's Houston cost data reports a low-to-high range of $500 to $5,500 for mold removal. Flood jobs that run through several rooms can go well past that; HomeGuide's 2026 national ranges put 300 to 1,000 square feet at $6,000 to $15,000. The bill depends on area, how much material comes out, containment and access, plus the assessor's separate fee. If a house is substantially damaged, meaning repairs reach 50 percent of its pre-damage market value, Bellaire's floodplain rules require bringing it up to current standards, which affects the rebuild budget more than the mold work itself.
