Mold in Walls & Drywall in Porter, TX

What happens when you call

You'll reach an independent company that works in the Porter area. They'll ask where the problem is, what's on the other side of the wall, how long it has been noticeable and whether the house has had storm or flood water. Then the Texas process takes over:

1. A mold assessment consultant who holds a TDLR license inspects, measures moisture and checks inside the cavity.
2. You receive a written protocol at least a day before work, listing the areas, quantities, protective equipment, containment and clearance criteria.
3. A different company, holding a TDLR mold remediation contractor license, removes the affected material according to its work plan.
4. The consultant performs the post-remediation assessment, and you get a Certificate of Mold Damage Remediation within 10 days of the job ending.

Cost factors

Angi's Houston cost data reports a $2,016 average for mold removal and a typical range of $863 to $3,329. On a wall job, the main variables are how many linear feet of drywall come out and how high, whether insulation and baseboards are wet, and whether a vanity, tub or cabinets must be removed. National ranges (HomeGuide, 2026) put small areas of 10 to 100 square feet at $500 to $1,500. The assessment consultant bills separately.

Porter's conditions

Porter is an unincorporated community in southeast Montgomery County with no official boundaries, loosely defined by the 77365 ZIP code, about 24 miles from Houston. During Hurricane Harvey, Montgomery County received about 36 inches of rain, and the sheriff reported Peach Creek out of its banks. Even without flooding, the area's humidity, wooded lots that keep walls shaded and damp, and attic AC equipment give hidden leaks plenty of time to grow mold. Because Porter is unincorporated, rebuilding after remediation falls under the Montgomery County Permit Department in Conroe, which lists an East Montgomery County phone line and requires a development permit for substantially damaged structures in the floodplain.

Checklist before the company arrives
