My problem was very unusual.  Jeff was very concerned that his intial attempt did not fix it.  I was just planning on living with the inconvenience of the door not closing properly during the day.\nHe rummaged in his truck and had a true MacGyver moment.  My door now shuts even when the sun is shining on the sensors.  He obviously cares about his business and his clients.  The price was also very reasonable.\nHighly recommended.
