The Importance of Replacing a Sliding Glass Door

A working sliding glass door acts as a seal against the outside elements. Glazing, reflectivity, and other variables contribute to keeping light and heat out or letting it in, allowing you to optimize the indoor climate. When it has a proper seal, the door keeps bugs and moisture out and makes life difficult for any would-be burglars.

Sliding doors that stick or panels that don’t seal properly are a few common indicators that it’s time for a replacement. You can caulk minor imperfections in seals around the frame, but eventually, it won’t be enough to keep water and critters out of the house. If you start feeling a draft or having trouble opening or closing the door, start shopping for a new sliding patio door.

How to Take Care of Your Sliding Glass Doors

Sliding glass doors are easy to maintain, but you need to clean them regularly. Hitting it with a glass cleaner weekly is essential in enhancing the look of your indoor space and allowing in more light.

Cleaning the tracks and gaskets once every few weeks will keep them from wearing out. Moisture and debris can accumulate in tracks, causing mold and rust to develop, while gaskets can dry out and crack from dirt buildup. Wash them with water and mild dish soap to keep the door sliding smoothly and sealing firmly.
