This Thank you note goes to the persons who provided a recommendation on companies to replace extension springs on a garage door. Here are the recommendations received: 1- Steel City Garage Doors (multiple times, with one negative on the price they charged), 2- Garage Door Doctor (2 times), 3- City Wide. Written proposal I got from Steel City was $ 503 with several add-ons I did not ask for, and GD Doctor was standard price-list, $170, which is exactly what I paid. GD Doctor was fast, very friendly, no frill, did not try to oversell services. good price. Jean F Guilleux --
