We had an issue with our garage door not going up and getting stuck, so we hired Garage Door Medics to come and fix it. They adjusted the extension because it wasn't going up properly and corrected the problem. Our garage door is old and is still having a lot of issues so we will probably get it replaced soon and would definitely call up Garage Door Medics to do that for us. They were fast, on time, and their customer service is great, definitely hire them if your garage door is having issues!
