Attic Mold Removal in Alvin, TX

Signs to look for

• Dark blotches on plywood or OSB decking, often near valleys, vents or the chimney
• A wet, musty smell when the attic hatch opens
• Insulation pressed flat or stained brown
• Rust in the drain pan or water on the pan's floor
• A ceiling stain or bubbling paint below the air handler
• Growth concentrated around a bath fan that vents into the attic

Alvin's rain record and what it means for roofs

Alvin, a Brazoria County city about 27 miles from Houston on SH 35 and SH 6, holds a famous rain record. In July 1979, Tropical Storm Claudette stalled over the city and dropped about 45 inches in 42 hours, including 43 inches in 24 hours, at the time the highest 24-hour total in American history. In 2008, Hurricane Ike damaged the Alvin Library badly enough that it closed for repairs. Storms like these find every weak point in a roof: lifted shingles, worn pipe boots and flashing gaps. A small leak can keep insulation wet long after the sky clears. Between storms, the AC coil in the attic drips into a pan all summer, and a clogged line overflows onto the ceiling. Bath fans ducted into the attic and soffit vents covered by insulation add trapped humidity that settles on the cooler decking overnight.

What affects cost

National ranges (HomeGuide, 2026) put attic remediation at $1,500 to $6,000 for part of an attic and $6,000 to $15,000 for a full one. Square footage, insulation depth, wood replacement, access and any duct work set the final price. Texas law adds a separate fee for the assessment consultant who writes the protocol and checks clearance afterward.

What happens when you call

You'll be connected with an independent local company. A mold assessment consultant who holds a TDLR license inspects the attic and writes the protocol; a separate company with a TDLR mold remediation contractor license removes and cleans; and you receive a Certificate of Mold Damage Remediation after clearance. City of Alvin Permits & Inspections requires permits for remodeling and repairs, and residential owners must show proof of homestead exemption before buying a permit.
