Why Sliding Glass Doors Start To Stick
Most doors do not go from smooth to broken in one jump. The change is gradual, and that is part of what makes the problem easy to ignore for too long.
Rollers do the heavy work every time the door moves. Once they wear unevenly, the slab no longer glides the way it should, and the whole unit begins to feel rough.

What Gaithersburg Homeowners Should Ask Before Replacing A Door

- Does the lock engage cleanly every time? Is the frame square, or does the door sit crooked? Are drafts, moisture, or noise coming through around the edges? Has the door needed repeated service in the last few years?
