Called company due to broken springs, they did respond in a very timely manor and the technician was very friendy and knowlegeable and completed work in a timely fashion
What I do have a problem with is the cost, springs were $330 per spring which upon research is a bit high but not out of the ball park
The replacement rollers, cables etc is another story, first I am not sure why he replaced and the prices based on my comparison of other on line parts (example Home Depot sells a pack of 2 rollers for less than 10 bucks, your charge $ 33.00 per roller, now I do understand there are safety checks and the argument these are "high quality rollers" but a bit to much mark up, and I am not even going to mention the torsion cable cost.
To note I take full responsibility for not fully understanding the cost, $1700 lesson learned
On a final note again the work was done professionally and the door is in good working order so I am pleased with the actual work.
