"I needed a new electric garage door mechanism. I received my quote quickly and we scheduled the date and time for installation. The installer did not arrive on time, but called to let me know that he was tied up a bit on the first job and would arrive as soon as he could. He came and did a great job of installing the opener and clearly explained the features and showed me how to use them. I appreciated the professionalism and ease of having my new electric garage door installed."

"I scheduled an on-site visit to determine if an automatic door opener could be installed and the representative came ready and able to go ahead and install the door opener at the same time.  It saved me having to schedule another visit to have the door installed. I am very pleased with the service.

"Work went very smoothly! They showed up on time, performed a full check and made several key adjustments to the motor. Suggested additional work which they priced very competitively and was done within minutes. They'll be installing our new garage door once we save up enough for that project :)"
