There is a huge difference in the useful life expectancy of doors. Interior doors – the ones that hang inside your house, between rooms or on closets – can easily last 100 years, especially if they are of high quality. Exterior doors are exposed to the elements, and the weather we have here in the South Shore area is tough on them. Top quality fiberglass or fire-rated steel exterior doors can last a century, but lower quality doors wear out quicker. Sliding glass doors are a special case. Because of the way sliding glass doors are built and used, they wear out far more quickly. The very best sliding glass doors will last approximately thirty years. Active families, especially those who use sliding glass doors several times a day to let children and pets in and outside, find that their doors don’t last that long.

Sliding glass door replacement keeps your family safer.
