We were getting a thumping noise when the garage door opened and closed. We called Sun City Garage doors and the sent Donnie out to fix it. He was courteous and very knowledgeable. He explained what was happening and different options to fix it at different price points. He explained pros and cons of each choice and really made it a comfortable decision for us. He installed new springs with a 1 year warranty and did a final adjustment on the track. It works so quietly and smoothly now it's like new again. They also fix water heaters. This was installed at Aunt Marina's House and she was very pleased with the experience.
