How can you distinguish between a legit and not so legit Walls garage door installers and repairmen?
The tech should make every effort to analyze the root cause of the problem, not just the problem itself. For example, say you called the repairman to get a quote on garage door spring replacement cost, because your door was opening slowly.
The technician could replace the spring and be on his way. But he could also make a very good case to talk to you about garage door panel replacement cost. This would increase his sale and the repair cost to the consumer, but it might also ensure fewer problems and better performance with the garage door in the years to come. The tech should explain the options and give you a choice.
