They left me worse off! They created more problems.
My garage door was getting stuck on one of the tracks, so I called their company based on all the good Yelp reviews. But, they ended up breaking my motor by forcing it and over adjusting.
I kept telling them the point where the door was getting stuck and suggesting it was the tracks possibly shifted by settling in the area. they just ignored me and proceeded to burn out a perfectly functioning motor and leaving me with a $395 quote to replace it.
