I highly recommend Chino Hills Garage Door and Gates Repair Services. I am very pleased with the staff, service and efficiency. The garage door opener is quiet and runs smoothly. I live in an old apartment building and was concerned if one could be installed for the solid old door that I have. The technician accessed the situation at no cost and came out the same day that I called. Came over to make sure that it could be wired in the building and got the OK and within a few hours I had the pleasure of an electric garage door opener.
