Post-Flood & Storm Mold in Houston

Rapid response after flooding, roof leaks and tropical storms, before the 24 to 72 hour window closes.

Mold can begin colonizing wet drywall, framing and insulation within 24 to 48 hours in Houston's heat and humidity. After flooding, the priorities are: remove standing water, pull wet porous materials (flood-contaminated drywall and insulation are removed, not dried), then dry the structure fully before anything is rebuilt.

Floodwater is category 3 ("black water"), which means sewage and bacteria exposure as well as mold. Do not reuse porous materials that were soaked by floodwater.

What the process looks like

  1. Stop water and document damage for insurance
  2. Remove wet porous materials
  3. Structural drying with dehumidifiers and air movers
  4. Antimicrobial treatment and HEPA cleaning
  5. Moisture re-check before rebuild

Frequently asked questions

How much does mold removal cost in Houston?

Small, contained jobs (a bathroom wall, one attic section) often run from several hundred to a few thousand dollars. Larger projects with containment, removal of drywall and insulation, and clearance testing commonly run into the five figures. The price depends on square footage, materials affected and access. See our cost guide for a breakdown.

Do I need a mold test before removal?

For projects of 25 contiguous square feet or more in Texas, a licensed mold assessor generally has to write a protocol before remediation starts. For smaller areas, a visual inspection and moisture survey may be enough. Testing is also the only objective way to confirm the cleanup worked.

Is black mold more dangerous than other mold?

"Black mold" usually refers to Stachybotrys, but color alone doesn't tell you the species or the risk. Any indoor mold growth should be removed and its moisture source fixed. See Mold Macro for the broader science.
