My garage door opener has not operated corrected for over a year when I came upon a coupon to have it checked lubricated and adjusted. I called them and the same day they sent one of their technicians out. He was one of the best persons that I have ever dealt with. He not only performed all necessary adjustment, he taught me how to correct and prevent any future problems. Mr. Lucas Nunez is a credit to their company, and I know if I have any other problems Welborn will be the only company that I will ever contact.
