We'd been having problems with a 16 year old garage door opener for two weeks. It would open but not close with the door openers. So changed batteries, got a new open... still it was sporadic...so sent in a request for help and Peter called in a short time and we set an appointment for that afternoon. Peter and Trevor explained it was a sensor and could be fixed but because of the age of the open and something else could happen it might be cheaper in long run to install a new open. They gave us choices and had the new one installed within the hour. They were very nice and did a great job. Thank you.
