I needed to have my garage door torsion spring replaced. After talking with the technician about the difference between each spring he had available I picked the most heavy duty one they had. Because my whole family enters and exits through the garage. My technician was very informative and took the time out to go over the pros and cons of each spring and why I should change the cables and pulleys at the same time I had him also change the rollers. I'm totally satisfied with the work done and quick service
