Mold Removal & Remediation in Friendswood, TX

Our house was repaired after Harvey. Why is mold showing up now?

Because repairs made in a hurry don't always dry the structure first. Harvey's rains caused 500-year flood events along Clear Creek all through Friendswood, and a preliminary estimate put about 3,000 homes inundated; the city issued 1,787 permits for Harvey repairs in 2017 alone. When drywall goes back over framing or a slab that never fully dried, growth can stay hidden until a smell or a stain gives it away. EPA's guidance is to dry water-damaged materials within 24 to 48 hours; anything wet longer should be treated as moldy. A consultant can open suspect walls and test framing moisture to find out how far the problem goes.

How much should I budget?

Angi's Houston cost data reports typical mold removal at $863 to $3,329, and HomeGuide's 2026 national figures run $15 to $30 per square foot. A single bathroom wall sits at the low end; several flood-damaged rooms can run far higher, with HomeGuide's national range for 300 to 1,000 square feet at $6,000 to $15,000. Texas requires the assessment and removal on the same project to be done by different companies, so budget for the consultant's protocol and clearance on top of the remediation contract.

Who do I deal with at the city?

Friendswood, founded as a Quaker colony in 1895 and incorporated in 1960, sits in northwestern Galveston County with a portion in Harris County, about 24 miles from Houston. Rebuilding after remediation goes through the city's Community Development department, which handles building permits and inspections. The city's Code Enforcement investigates substandard and dangerous buildings through its Submit a Concern form, a route for renters whose landlord hasn't fixed a leak. The Galveston County Health District lists mold among complaints outside its jurisdiction.

A note for sellers

Keep your Certificate of Mold Damage Remediation. Texas requires sellers to give buyers each certificate issued for the property in the past five years. For a home, the certificate can also help keep an insurer from making an adverse underwriting decision based on the earlier mold damage, though it doesn't promise anything about a claim. If you can't get one because the work was done by people without a TDLR mold license, a TDLR mold assessment consultant or an adjuster may be able to provide a certification instead.
