Top notch service! The coil spring on my garage door snapped, and Door Doctor came the very next morning (at the promised 8am) to fix it. Mike was friendly, very quick and efficient, and did a great job. However we then discovered that the 20-yr old automatic opener was dead (the lack of spring meant that the opener gears head shredded themselves due to the extra door weight). So he offered to come back 2 days later to install a new opener. So 2 days later (again, at the promised time), Mike removed the old opener and installed the new one which I had purchased from Lowe’s the previous day. Clean, professional, efficient installation. All-round excellent service! I would not hesitate to use Door Doctor again, nor to recommend them to others!
