Black Mold Removal in Kemah, TX

Signs to look for

• Black spots on window frames and sliding-door tracks facing the water.
• A musty smell in a home or short-term rental that sat closed with the AC off.
• Dark growth on the underside of a raised floor or along the bottom of exterior walls.
• Speckling on ceilings near supply vents.
• Stains under sinks and behind appliances.

Kemah conditions

Kemah is a small waterfront city 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. Hurricane Carla severely damaged the city in 1961, and Hurricane Ike destroyed homes and businesses in 2008; Ike's storm surge hit the Kemah Boardwalk hardest, and a waterline inside Landry's Restaurant still marks the flood height. Beyond storms, the everyday driver is humidity. Homes that sit empty between visits, with the AC turned off or set high, can grow dark mold on walls and furniture within a season. Keeping indoor humidity below 60 percent, as EPA recommends, matters most in properties nobody checks often.

What affects the cost

Angi's Houston cost data reports mold removal averaging $2,016, with typical jobs from $863 to $3,329. Raised or elevated homes can add access work; growth in several rooms or in the ductwork adds more. HomeGuide's 2026 national figures put HVAC and duct remediation at $2,000 to $10,000. Texas law also requires paying a separate mold assessment consultant.

After you call

You'll talk with an independent local company. For anything beyond a small cleanup, a consultant who holds a TDLR license writes the protocol, a different company with a TDLR remediation license performs the removal, and the consultant confirms clearance. If the area covers 25 contiguous square feet or more, the remediation company must notify TDLR at least five days before starting. After a pass, the contractor gives you before-and-after photos and a Certificate of Mold Damage Remediation, which you'll need to pass along to a buyer if you sell within five years. All Kemah permits and inspections, including for rebuilding, go through the City of Kemah Building Department's MyGov portal, and its permits page links the city's flood chapter of the municipal code.
