Wow, what great service 1st call Garage Doors gave us today. We have a single garage door but with installation on all panels and that we have (1) spring was how we bought home. After doing some research on web I found out that most developers put in (1) spring to save money.. (2) springs really are faster and less wear on motor, as I have American Home Shield to replace or fix items in home they don't cover springs so I call around to hear different ideas and prices and how they are the best. Well the company that American home shield recommend was $380.00 for rollers and (1) spring.. I called 5 other garage company's and to find prices for (2) springs and all replace all wheels was anywhere from $450-550.. (1) spring & rollers $380 $450. I got lucky and called 1st Door explained my problem gave me quote, (2) springs all replaced rollers and 1 hour later Ryan was done with job and works smoothly and faster going up. Price was the far better than any of the quotes I got.. Happy Happy. Please call this company to have your Garage door work done I really don't think you can have better service.. By the way when your spring breaks I swore someone kicked in my front door as this happened at 11:30 at night.
