it's only a matter of time before those springs go in your garage, and these are the guys you want for the repair. I called for an estimate and they made an appointment to come look at my garage door. We had a miscommunication so nobody made it to my house. When I called back a was quoted over the phone based on my description of the problem so I made the appointment for replacement spring for the next day. These guys were a lot less and I read some of the favorable reviews here.
Mike called me when he was on his way and he began work soon as he arrived. They offer springs based on usage and some last longer than other and are just a little more expensive. The work was done in about 20 mins. Mike came back and showed me what to put on the chain and rollers to help keep them lubricated for more longevity. Very friendly and did a great job. The door works great and makes less noise after the work, my dog doesn't even hear the door opening, maybe too quiet..LOL. If you need work done give these guys a call, I know I would use them again when something goes wrong.
