This glass door on the left seemed easy to change until we removed it and discovered the subfloor was about to throw in the towel. One simple door required us to correct the the flooring with new beams AND we also had to build new headers (above the sliding door) because it too wasn't properly positioned. We had to build a temporary wall to ensure the roof wouldn't collapse while we replaced the original header.

Give us a call, we're happy to help.
