I had a garage door that was complaining about the safety sensor for over a month. Finally I decided to give Brendan a call to check it out. He showed up within 30 minutes of calling him and fixed the issue in a minute. It was just a matter of adjusting the safety sensor which was slightly off the rails. I offered to pay him for his troubles but he didn't charge me a dime. Great service and I will definitely use him the next time I have any issues with my garage.
