Heat, Cold and Garage Doors in the Treasure Valley
The Treasure Valley has a semi-arid climate with four distinct seasons. Each one works on a garage door differently. A little seasonal attention keeps doors running smoothly and catches problems before they strand a car.
The climate in brief
NOAA's long-term climate normals describe Boise as semi-arid, with hot, dry summers, cold winters and relatively low annual precipitation (NOAA NCEI U.S. Climate Normals). The National Weather Service Boise office forecasts the area's heat waves, winter cold snaps, valley inversions and wind events (National Weather Service Boise).
Summer: heat and sun
- Seals: rubber and vinyl bottom seals and side weatherstripping dry out, harden and crack under strong sun.
- Dark doors: dark-colored steel doors facing west or south absorb a lot of heat. Some door makers limit dark colors on certain models for that reason.
- Attached garages: an uninsulated door can make rooms next to or above the garage hotter. The U.S. Department of Energy's Energy Saver pages discuss how garages and air sealing affect home comfort (U.S. Department of Energy, Energy Saver).
- Sensors: low afternoon sun can interfere with photo-eye sensors on west-facing doors.
Fall: dust and prep
Dry summers leave dust and grit in tracks and on rollers. Fall is a good time to wipe tracks clean (do not grease them), lubricate rollers, hinges and springs with a garage door lubricant, and replace a cracked bottom seal before the cold arrives.
Winter: cold and ice
- Springs: fatigued springs are more likely to break in the cold.
- Lubricant: heavy grease thickens and makes the opener work harder.
- Frozen seals: a bottom seal can freeze to the slab. Forcing the door with the opener can tear the seal or strain the motor.
- Inversions: during winter inversions, cold air can sit in the valley for days, keeping garages cold and damp.
Spring: wind
Strong wind days bring dust and push on partly open doors. Wide double doors catch the most wind. Closing doors fully in gusty weather helps, and struts can stiffen wide, light doors.
A simple seasonal checklist
- Watch and listen to the door open and close; note new noises.
- Test the auto-reverse and photo-eyes monthly.
- Check door balance once or twice a year.
- Lubricate moving parts in spring and fall.
- Replace worn seals before summer and winter.

Short answers
Why does my door stick in winter?
The bottom seal may be frozen to the floor, or thick grease is slowing the rollers and opener.
Does heat damage garage doors?
Sun and heat wear out seals and can affect dark, uninsulated steel doors.
Should I grease the tracks?
No. Keep tracks clean and lubricate rollers, hinges and springs instead.
Does an insulated door help in summer?
Yes, especially in attached garages facing west or south.
