On Friday (04/10/20), Mr Preston Uecker installed a new garage door opener (Model 8550WLB) and associated components that are required with this new installation, at my home. Preston was very efficient, and when completed, he explained everything I needed to get familiar with the new system, very clearly. Been a customer with Garage Door Medics for 5 years or so and always enjoy the company's technicians work ethic and professionalism every time they come out. I always schedule an yearly garage door tune-up at a very reasonable cost. Recommend you do the same and call, Garage Door Medics (844-792-6866)
