I purchased a coupon on Angie's list for a garage door tune up. The technician arrived right on time, oiled up various parts of the system, tightened all the bolts on the door, did a diagnosis of additional work that would be needed in the near future (my door is 14 years old) and left without pressuring me into getting the additional work done. Very efficient and reliable is the best way to summarize my experience with Welborn.
