In Kemah, wall mold usually begins with water pushed into the house by bay storms, or with quieter sources like roof, window, plumbing and AC drain leaks that kept drywall wet. After the source is fixed, the damaged board is cut out under containment following a separate consultant's protocol. Call the number on this page to be connected with a local mold remediation company in Kemah.

Signs of mold inside a wall
- Bubbles or cracks in paint on a bay-facing exterior wall
- Brown streaks below a window after a storm
- A musty odor in a ground-floor room or closet
- Drywall that is soft along the bottom edge
- Recurring stains under the attic air handler
What Kemah homes are up against
Kemah is a small waterfront city of about 1,800 people on the west shore of Galveston Bay, about 30 miles from Houston, with the Clear Creek Channel at its northern end and Clear Lake nearby. Storms have reshaped it more than once. Hurricane Carla severely damaged the city in 1961, and Hurricane Ike destroyed homes and businesses, with storm surge hitting the Kemah Boardwalk hardest; a waterline inside Landry's Restaurant marks how high it rose. Between big storms, the bay keeps the air humid, wind drives rain sideways into siding and window frames, and AC systems run for much of the year. Drywall that soaks up any of that moisture and stays wet for more than a day or two is likely to grow mold on the side you can't see.

What drives the cost
Angi's Houston cost data reports mold removal averaging $2,016, with a typical range of $863 to $3,329. Larger storm-related jobs can run higher; national ranges (HomeGuide, 2026) list 100 to 300 square feet at $1,500 to $6,000. The amount of wall opened, wet insulation, built-ins in the way and multi-room containment all matter, and the mold assessment consultant is billed separately under Texas law. Kemah handles all permits and inspections through its MyGov portal, and its Permits and Inspections page links Municipal Code Chapter 46 on floods, which is worth reading before rebuilding a flood-damaged wall.
What happens when you call
An independent local company will ask what you're seeing, where, and whether storm water got into the house. A consultant who holds a TDLR license inspects and writes the protocol; a different company that holds a TDLR mold remediation contractor license does the removal; and the consultant confirms clearance before the wall is closed. Before work begins, you should also receive TDLR's Consumer Mold Information Sheet, and you can check both companies on TDLR's license search. Keep the Certificate of Mold Damage Remediation you receive afterward with your storm repair records.
