Your Therma-Tru door system can bring your home years of durability, beauty and energy-efficiency. But like windows and other parts of your home, your door may require a little maintenance from time to time.

You’ll want to inspect your Therma-Tru door systems and associated components at least once a year.  

Check your door system for:

  • Fading of door finishes

  • Weatherstrip seal inadequacies

  • Door bottom gasket or sill gasket wear

  • Vinyl threshold or oak riser splitting or cracking

If any of the components fail to function upon inspection, they should be repaired or replaced. If you’re noticing a specific issue, use our Troubleshooting Guide.

When in doubt, your building professional can also help you inspect and maintain your door. Watch our video for more tips.
