Charlotte, NC

As summer temperatures soar, it’s important to remember that extreme heat can have a significant impact on your home’s doors. Heat can cause doors to warp, expand, and deteriorate, compromising both their appearance and functionality. At A1 Lion Locksmith in Charlotte, NC, we understand the importance of maintaining your home’s security and aesthetics. Here are some essential tips to protect your doors from the heat and keep them in top condition all year round.

1. Choose the Right Material

The material of your door plays a crucial role in how well it withstands heat. Here are some common door materials and their heat-resistance properties:

  • Wood: While wood doors offer a classic look, they are prone to warping and cracking in extreme heat. If you prefer wood, choose a high-quality, heat-resistant wood species, and ensure it’s properly sealed and treated.

  • Steel: Steel doors are durable and resistant to warping, making them a good choice for hot climates. However, they can get very hot to the touch, so consider adding an insulated core.

  • Fiberglass: Fiberglass doors are highly resistant to heat and humidity, making them an excellent choice for withstanding summer temperatures. They are also low-maintenance and can mimic the appearance of wood.

2. Apply a Protective Finish

For wood doors, applying a high-quality, UV-resistant finish can help protect the wood from heat and sun damage. This finish acts as a barrier, preventing the wood from drying out and cracking. Reapply the finish regularly to maintain its protective properties.

3. Install Weather Stripping

Weather stripping is essential for keeping out hot air and preventing your door from expanding and contracting due to temperature changes. Install weather stripping around the edges of your doors to create a tight seal. This not only protects your doors but also improves your home’s energy efficiency by keeping cool air inside and hot air outside.

4. Use Door Awnings or Shades

Installing an awning or shade over your exterior doors can provide much-needed protection from direct sunlight. These additions help reduce the amount of heat your doors are exposed to, minimizing the risk of warping and fading. They also add an extra layer of insulation, keeping your entryway cooler.

5. Keep Doors Clean and Maintained

Regular maintenance is key to prolonging the life of your doors. Clean your doors periodically to remove dirt, dust, and debris that can cause damage over time. For wood doors, use a mild soap and water solution, and avoid harsh chemicals that can strip the protective finish. Inspect your doors regularly for signs of wear and tear, and address any issues promptly.

6. Insulate Your Doors

Insulating your doors helps regulate their temperature and prevents heat from seeping through. For solid doors, consider adding an insulated core. For doors with glass panels, use double or triple-pane glass with a low-emissivity (Low-E) coating to reduce heat transfer.

7. Repaint or Stain Periodically

Repainting or staining your doors periodically can help protect them from the elements. Choose a high-quality, exterior-grade paint or stain with UV protection to shield your doors from sun damage. Reapply the paint or stain every few years, or as needed, to maintain a strong protective barrier.

8. Consider Door Covers or Curtains

For doors with glass panels or sidelights, consider using door covers or curtains to block out direct sunlight. These additions can significantly reduce the amount of heat entering your home and protect the door from excessive heat exposure. Choose light-colored or reflective materials to maximize their heat-blocking capabilities.


Protecting your doors from the heat is essential for maintaining their appearance, functionality, and longevity.
