Dayton and the Trinity

Dayton is a Liberty County city of about 8,800 on US 90, roughly 38 miles from Houston. It was founded as West Liberty, about three miles west of the Trinity River, and grew into a Union Pacific and BNSF rail junction with a BNSF yard just south of town; about 78 percent of residents are counted as urban. During Harvey, releases from Lake Livingston into the Trinity matched the 1994 record, and more than 7,000 homes across Liberty County were affected, about 800 with major damage or destroyed. Away from the river, Dayton shares the region's usual moisture sources: tropical downpours on flat, slow-draining ground, storm-damaged roofs and AC systems that run most of the year.

What affects cost

Angi's Houston cost data shows an average of $2,016 for mold removal, typically $863 to $3,329. Flooded homes often need more; national ranges (HomeGuide, 2026) put 300 to 1,000 square feet at $6,000 to $15,000. Your quote depends on the wet area, materials removed, ducts, access, and the separate assessment consultant Texas requires. Ask each company for a written scope so you can compare quotes against the consultant's protocol line by line, and check both on TDLR's license search.

What happens when you call

You'll describe the source and extent of the water and be connected with independent local companies. A mold assessment consultant writes the protocol; a separate remediation company carries it out under containment; for 25 contiguous square feet or more, it notifies TDLR five days before starting; and after clearance you receive a Certificate of Mold Damage Remediation. For the rebuild, the City of Dayton Building Division under Planning & Development Services issues residential permits; plan review for new construction can take up to 10 days, and inspections are generally required for each permit.
