# Preparing Your Garage Door for Hot Weather: Essential Tips
As temperatures rise in New Hampshire, your garage door faces unique challenges. Heat can affect metal components, lubrication, and overall performance. Here's how to keep your garage door operating smoothly all summer long.
High temperatures cause metal tracks, springs, and hardware to expand. This can lead to:
- Binding or sticking during operation - Increased wear on moving parts - Slight changes in door alignment
Heat can cause lubricants to thin out or evaporate faster than normal, leading to:
- Increased friction and noise - Faster wear on rollers and hinges - Potential for metal-on-metal contact
Rubber weatherstripping can deteriorate faster in heat:
- Becomes brittle and cracks - Loses its seal, allowing hot air and pests inside - May need replacement more frequently
Apply a silicone-based lubricant to:
- Rollers and hinges - Tracks (lightly) - Springs - Pivot points
Avoid petroleum-based products that can attract dust and dirt.
Examine the weatherstrip along:
- Bottom of the door - Sides and top - Between door panels
Replace any that shows cracking, gaps, or compression damage.
An unbalanced door works harder:
1. Disconnect the opener 2. Manually lift the door halfway 3. Let go – it should stay in place 4. If it moves up or down, call for professional adjustment
Look for:
- Loose bolts or screws - Worn rollers - Damaged cables - Rust or corrosion
- Wipe tracks with a clean cloth - Remove debris from the garage floor - Clean safety sensor lenses
Keep your garage cooler and reduce energy costs:
Insulated Doors: If you don't have one, consider upgrading to an insulated garage door. It keeps the garage cooler and reduces heat transfer to your home.
Weatherseal: Ensure all weatherstripping is in good condition to prevent hot air infiltration.
Ventilation: Consider adding garage ventilation to reduce heat buildup.
Light Colors: If replacing your door, lighter colors reflect more heat.
