I called these guys recently in the early evening, when our garage door wouldn't open and the cables were hanging off on the sides.
I spoke with Nazar on the phone and he said it was the Spring. I said how do you know if you haven't even seen it. He said, I've been doing this a long time and I'm 99% sure.
As agreed, Olek came over the next day at noon, and said, "See the spring is broken." I looked up and presto, the screen was in two pieces. Within 30-40 minutes, Olek had a new spring installed and proceeded to spray lube all the moving parts of the door he fixed, PLUS our other garage door.
I would not hesitate to recommend these guys!
Amazing, friendly service that spells WOW!
