Post-Flood Mold Removal in Cypress, TX

Signs to look for after the water drops

• Brown or dark staining that climbs the drywall from the floor
• Paint peeling or blistering on lower walls
• Carpet that stays damp at the edges or smells sour
• Growth on the back of baseboards when they are pulled
• A musty odor from the return grille once the AC is back on

Flooding in Cypress

Cypress is a large unincorporated community in northwest Harris County, about 20 miles from downtown Houston, built out from former rural land into master-planned communities since the 1980s and 1990s. The Harris County Flood Control District lists Cypress, in the Little Cypress Creek watershed, among the hard-hit communities of the April 2016 Tax Day Flood, and some homes that flooded in April flooded again in the Memorial Day storm a month later. During Hurricane Harvey about 30 inches of rain fell along Cypress Creek; homes in Norchester and Lakewood Forest flooded significantly, as did areas near FM 529, while many other parts of Cy-Fair stayed dry. That uneven pattern means one street can be gutting walls while the next is fine.

What affects the price

Angi's Houston cost data reports mold removal at $2,016 on average, with a low-to-high range of $500 to $5,500. Creek floods that reach several rooms often go beyond it; national ranges from HomeGuide (2026) list $15 to $30 per square foot and $15,000 to $30,000 for a whole house. In Cypress the big variables are:

• Water depth and the number of rooms affected
• Days the house sat wet before drying began
• Whether the home has flooded before and has hidden older damage
• Cabinets, stairs and built-ins that must be opened up
• Two sets of fees: the assessment consultant and the remediation company

What happens when you call

You will be connected with an independent remediation company that serves Cypress. It will ask about the flood depth, timing and drying so far. Before removal, a mold assessment consultant from a different company writes the protocol and gives it to you at least a day ahead; the remediator adds a work plan and notifies TDLR if the area is 25 contiguous square feet or more. Afterward, the consultant checks clearance. Rebuilding is permitted by the Harris County Office of the County Engineer.
