I,m puttin up a 2 car garage for a customer and were almost done. Garage doors went up on Tues. and on Wens. the customer tells me that while playing with the new doors the slide lock got caught on the track and now the electric opener does not work. After inspecting the doors I find that the track is now bent and binding the door. I have told the customer that I would call the door company back for the repairs and if there was a charge that they would be responsable for the charges. I also informed them not to play with any other items until we had a walk through so I could show them proper use of all aspects of the new garage, Hot tub, lights, ect. they were ok with that but they did point out that it was their house and they would be walking through to inspect the work as it was completed. Now do I ad a new clause to my contract so it doesn't happen again? or do I tell each new customer not to touch anything?
