Preparing Your Garage Door for Hot Weather: Essential Tips

2025-01-08 6 min read

Why Hot Weather Affects Your Garage Door

High temperatures can cause metal components to expand, lubricants to thin, and weatherstripping to degrade. In the mountain climates of Western North Carolina, where we see significant temperature swings between day and night, proper preparation is essential. At Cashiers Garage Doors, we help homeowners prepare their garage doors for every season, and summer presents its own unique challenges.

The expansion and contraction of metal components during hot days can lead to increased friction, unusual noises, and even binding or sticking. Understanding these effects helps you take proactive steps to prevent problems before they occur. Our service area, including Highlands, Cashiers, and the surrounding mountain communities, experiences intense summer sun that can put significant stress on garage door systems.

Inspect and Replace Weatherstripping

The rubber seals around your garage door can crack and become brittle in extreme heat. These seals are crucial for maintaining energy efficiency and keeping pests, dust, and debris out of your garage. Check all weatherstripping and replace any sections that show signs of wear. Look for cracks, gaps, or areas where the seal no longer makes firm contact with the floor or frame.

Bottom seals are particularly susceptible to sun damage and wear. A damaged bottom seal can allow hot air into your garage, raising temperatures and increasing cooling costs if you have an attached garage. We recommend inspecting seals at least twice a year, ideally before summer and winter. If you need assistance, our technicians can replace weatherstripping as part of a maintenance visit.

Lubricate Moving Parts

Before summer arrives, apply a high-quality silicone-based lubricant to all moving parts including hinges, rollers, and springs. Avoid using WD-40 as it can attract dust and debris, which creates a grinding paste that accelerates wear. Instead, use a lubricant specifically designed for garage door systems.

Pay special attention to the roller bearings, spring coils, and hinge pivot points. These areas experience the most friction and benefit greatly from proper lubrication. A well-lubricated door operates more quietly and puts less strain on your opener motor. We recommend lubricating your door every three to four months, or more frequently if you use your garage door multiple times daily.

Check the Balance

Temperature changes can affect your door's balance. Disconnect the opener by pulling the emergency release cord and manually lift the door halfway. If it doesn't stay in place, the springs may need adjustment. A properly balanced door should stay in place at any position when released.

Spring tension adjustment is a dangerous task that should only be performed by trained professionals. The springs are under extreme tension and can cause serious injury if mishandled. If your door is out of balance, contact our team for a safety inspection and adjustment. We offer same-day service for most balance issues.

Consider Insulation

If your garage gets extremely hot in summer, insulated garage door panels can help regulate temperature and reduce energy costs. This is especially important if you use your garage as a workshop, home gym, or living space. Insulated doors also help keep your garage cooler, which can protect vehicles and stored items from heat damage.

Modern insulated doors feature polyurethane or polystyrene insulation with R-values ranging from 6 to 18+. Higher R-values provide better insulation. If you're considering upgrading to an insulated door, our team can help you choose the right option for your needs and budget.

Protect the Finish

UV rays can fade and damage your door's finish over time. For wood doors, apply a UV-resistant sealant or stain annually. For metal doors, wax or apply a UV protectant to maintain the finish. Regular cleaning also helps prevent buildup of dirt and debris that can trap moisture and accelerate deterioration.
