Patio doors get heavy use, and over time sliding doors start to drag on worn tracks while French doors sag, rub, and stop latching cleanly. Large panels of older glass also let heat and cold pass straight through, so the rooms beside them are often the least comfortable in the house. Gaps around a tired patio door invite drafts, insects, and rainwater, and a door that is hard to lock is a security weak spot at the back of the home. At Southern View Windows & Doors, we replace sliding and French patio doors so the connection between your indoor and outdoor living spaces works the way it should.
