Answer-first
The best East Texas window for exterior sealing is late October — after peak humidity has broken and before the first cold snaps drive rodents indoors. Focus areas: garage door bottom and side seals, window frame caulking, brick weep-hole screens, dryer vent covers, and gable vent screens. Two hours of work heads off a whole winter of problems.
When this applies to your East Texas home
- It's late September through early November
- You've seen rodent activity in past falls or winters
- Your garage door has visible daylight along the bottom or sides
- Window caulking has cracked or shrunk over the summer
- You have gable vents with damaged or missing screens
Failure modes we see in the field
- Waiting until you see a rodent: sealing before the first cold snap is preventative; sealing after is a race against an active population
- Caulking weep holes: causes moisture damage; use copper mesh or dedicated weep-hole screens
- Sealing gable vents completely: attics need airflow — screen with 1/4-inch hardware cloth, don't block
- Skipping the garage door side seals: bottom-only leaves inches of gap on each side

Frequently asked
Why late October specifically?
By late October, East Texas humidity has dropped enough for silicone and caulk to cure properly, but cold weather hasn't yet driven rodents to seek indoor shelter. It's the ideal 3-week window before the annual rodent migration inside.
