I had a sliding glass door that barely opened, I asked a couple of friends of mine who did windows and doors look at it and they said we needed a new door, our door is oversized so it was going to be expensive. I was referred to the Glass Guru by a friend and thought I would have them check it out. They said it just needed some new wheels and they could take it apart and fix it!! It was only a couple hundred bucks! They saved me thousands of dollars!! Great service and so honest! I called them saying I needed a bid for a new door, they told me I didn't need one...not too many contractors do that!!
