Attic Mold Removal in Tomball, TX

Tomball at a glance

Tomball is a small city in northwest Harris County, about 24 miles from Houston, that grew up around the railroad after 1906 and sits on SH 249 and FM 2920 (Main Street). Spring Creek and Willow Creek shape its flood maps, and the city stresses that homes outside the mapped floodplain can still take water. During Harvey, floodwater reached homes near Spring, Willow, Mill and Walnut creeks even though the city saw relatively little damage overall. For the attic, the bigger day-to-day risks are a hot, humid climate, AC equipment above the ceiling and heavy rain that tests every roof penetration.

What to do now

1. Stop the moisture: have an HVAC technician check the drain and pan, or a roofer check the leak.
2. Photograph the growth and any ceiling stains with the date.
3. Avoid scraping or sanding the mold, which spreads spores.
4. Book a mold assessment consultant to inspect and write a protocol.
5. Choose a separate company with a TDLR remediation license to do the work, and verify both on TDLR's license search.
6. Ask the City of Tomball Building Division whether decking or framing replacement needs a permit; applications go through the city's SmartGov portal.

What you see and the likely cause

Cost factors

Angi's Houston cost data shows typical mold removal at $863 to $3,329, averaging $2,016. National ranges (HomeGuide, 2026) for attics are $1,500 to $6,000 partial and $6,000 to $15,000 full, with labor at $75 to $120 per hour. In Tomball homes, cost follows the affected area, insulation depth, access, wood replacement and duct work, plus the separate assessor's fee that Texas law effectively requires. A small spot over the air handler might stay near the low end of the Houston range, while a full attic with soft decking will not. Get the scope in writing from both companies before work begins.
