AC & Air Duct Mold Removal in Kemah, TX

Signs to check

• Dark dots or fuzz on supply registers
• A musty puff at the start of each cooling cycle
• Rust flakes or standing water in the drain pan
• Ceiling stains around grilles or under the air handler
• Duct insulation that's wet or sagging in the attic
• Indoor humidity that won't drop below 60 percent

Kemah conditions

Kemah is a small 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. It grew from a fishing town into a destination centered on the Kemah Boardwalk. Hurricane Carla severely damaged the city in 1961, and in 2008 Hurricane Ike destroyed homes and businesses, with its storm surge hitting the Boardwalk hardest; a waterline inside Landry's Restaurant marks the flood height. Homes and buildings rebuilt since then still face moist bay air every day. Salt exposure can corrode metal drain pans and coils, a rusted pan leaks, and condensation that should drain away soaks into insulation and ceilings instead. Inside, ducts running through hot attics sweat wherever insulation has slipped. Rental units and vacation homes that sit closed up with the AC off for weeks can turn musty quickly, because humidity builds with nothing pulling it out.

What affects cost

National ranges (HomeGuide, 2026) put HVAC system or duct mold work at $2,000 to $10,000. In Kemah, corrosion that forces replacement of a coil or pan, the amount of flex duct to replace, long or awkward duct runs, and attic access all influence the figure. Commercial spaces along the waterfront are scoped differently from homes. Texas law also means a separate fee for the mold assessment consultant, who writes the protocol and returns for the clearance check.

What happens when you call

You'll be connected with an independent local company. A mold assessment consultant who holds a TDLR license inspects and writes a protocol, a separate remediation company carries it out, and a post-remediation assessment confirms clearance. Replacement ducts or equipment go through the City of Kemah Building Department, where permits, inspections and contractor registrations run through the MyGov portal; its page links to the city's flood chapter, Municipal Code Chapter 46. The Galveston County Health District lists mold as outside its jurisdiction.
