We had a sudden and extremely dangerous situation occur, as the 2 x 6 board that secures the garage door mechanism and garage door opener to the garage wall came completely loose. We were in danger of personal and/or property injury due to the tension in the door spring. Zoran, the technician, came on short notice and was able to relieve the spring and make repairs without damage--no small feat!! The repair required new cabling and re-tensioning the spring, along with some tune-ups. The door works better than ever. Thanks Zoran and Precision!
