Local conditions in Dickinson

Dickinson is a Galveston County city about 32 miles from Houston, with Dickinson Bayou flowing in and out of town. During Harvey, about 90 percent of the city flooded and about half was destroyed by flooding. Homes rebuilt after that may have new ductwork, but some kept air handlers or duct runs that took water and were dried and reused. EPA's disaster guide says to assume mold where materials could not be dried within 24 to 48 hours, and duct liners and insulation hold water well. Beyond flood history, the usual suspects apply: a long cooling season, coils that stay wet for months, condensate lines that clog, and attic ducts that sweat when their insulation tears.

What affects cost

National ranges (HomeGuide, 2026) put mold work on an HVAC system or ducts at $2,000 to $10,000, and Angi's Houston cost data reports general mold removal averaging $2,016. A Dickinson job moves within that range based on how much duct is replaced, whether equipment from the flood era has to go, attic access and HVAC repairs to pans and drains. The assessor who writes the protocol and checks clearance is a separate company under Texas law, so that fee is in addition.

What happens when you call

You're connected with an independent local company. A mold assessment consultant who holds a TDLR license inspects and writes a protocol, a different company performs the removal, and the consultant confirms clearance before you receive a Certificate of Mold Damage Remediation. Replacement ducts or equipment may need a permit from the City of Dickinson's Building Permits & Inspections Division, whose page also posts the FEMA Elevation Certificate form. Renters with unrepaired leaks can use the city's online Report a Code Violation form. The Galveston County Health District does not handle mold.
