A grounded 2026 ballpark for Katy-area homes — not a quote.
Estimates use 2026 Gulf Coast labor and disposal costs: a $10–30/sq ft base, adjusted for how porous the affected materials are, with surcharges for toxic-appearing mold and HVAC contamination.

Mold help in Sugar Land →Built on a slab, wrapped in humidity
Most Katy homes are slab-on-grade, with no crawl space to vent moisture and an air handler that runs for the better part of the year. That combination — warm, wet outdoor air meeting cold AC surfaces — gives mold a reliable food source even in homes that have never flooded.
Add the flooding that does happen here. Harvey put feet of water into neighborhoods across Katy and Cypress, and the controlled releases from the Barker and Addicks reservoirs kept some homes wet for weeks. When water sits that long, mold isn't a question of if but how far.
