I actually found Garage Door Medics on Angie’s List, but wanted to write a review here, since I had a great experience.
I called on a Sunday morning, and Eric was at our house within an hour. He was professional, worked quickly, and didn’t push any unnecessary repairs or replacements. He also honored a special coupon, which made my double spring replacement very reasonably priced. I do think that without the coupon, the repair would have been more expensive than other options, but they seem to have coupons all the time, so use them!
