I had my back slider door replaced, as well as having a window removed and replaced with a much larger garden window. These guys were professional and FAST. It was done in a day, and it looks great. They even custom stained some trim to match the rest of the trim in the room. Total pros.
Now fast forward 6 years....the latch on the sliding door broke. No big, its wear and tear. So I called R&M to see if I could purchase a replacement part, or to ask where I might be able to get one if they didn't have it.
