I really need more than 5 STARS to express how happy and satisfied I am to have my new garage door openers. The old "relics" were long overdue for replacement. Because they were quite unique and "ancient" Jon had to invest EXTRA time and ingenuity into the project of placing new components. All the Liftmaster mechanisms are functioning safely and perfectly and QUIETLY. I would highly recommend TGS and your installer Jonathan Russomanno to anyone in need of garage door services.
