Attic mold in Guy homes typically grows from a roof leak, an AC drain pan that overflows or humid air that cannot escape. A small patch can often be handled by the homeowner once the source is fixed, while larger areas are better removed under a Texas protocol. Call the number on this page to be connected with a local mold remediation company in Guy.

Guy and its homes
Guy is a small unincorporated farming community at State Highway 36 and FM 1994 in Fort Bend County, about 2 miles southeast of Needville and roughly 36 miles from Houston. Homes here are spread out across farm country, from houses near the original Old Guy town site to others along the highways. Whatever the age of the house, the climate is the same humid Gulf Coast one: long summers, an AC that runs most of the year and heavy tropical rain. In homes with ductwork or an air handler in the attic, condensation is a steady source of moisture. Roof leaks after storms and attic vents blocked by insulation or debris are the other usual reasons decking stays damp.
Small spot or large area?
| Size of the growth | What the guidance says | Practical next step |
|---|---|---|
| Under about 10 sq ft | EPA: in most cases a homeowner can handle it | Fix the source, wear an N-95, clean or replace the material |
| 10 to 25 sq ft | EPA points larger areas to its professional remediation guidance | Consider an assessment, especially if wood is soft |
| 25 contiguous sq ft or more | A remediation company must notify TDLR five days ahead | Assessor's protocol, separate remediator, clearance |
Homeowners can always clean their own home in Texas; the 25 square foot line matters for owners of residential properties with 10 or more units and of non-residential property, and for how a hired company has to run the job.

Signs to check
- Dark growth on decking or rafters
- Damp, flattened insulation
- Rust in the AC drain pan
- Ceiling stains in rooms below
Timing and local offices
Check the attic after storms and before summer heat sets in. Fort Bend County Engineering issues development permits in unincorporated areas for floodplain work and building modifications above its size threshold, so ask before replacing decking or framing. Fort Bend County Health & Human Services does not take mold complaints. Because Guy is a longer drive from Houston, photos of the attic help the company plan the visit. Angi's Houston cost data puts typical mold removal at $863 to $3,329, and national attic ranges (HomeGuide, 2026) run $1,500 to $6,000 for part of an attic.
