First I would highly recommend Paul for any of your garage door needs. He was punctual, open about all our options, and kept to his estimated price (in fact the final price turned out to be lower than the estimation).
A little background on the problem: After the cold snap this winter the garage springs and pulleys started screeching as if under heavy stress until one of the pulleys snapped and shot the spring into one of the bars holding up the garage rails, bending the bar in the process. After calling Paul, he came the same day, took a look at our garage door and explained to us in detail what happened with the door and why it happened. We eventually decided to completely replace the springs system and go back to a drum cable system (which is better for heavier doors like our 141 pound wooden garage door). Paul did an initial estimate of the cost with the additional parts and scheduled to come back the very next day to complete the job. He even offered to work around our schedule to make it easier on us. The whole replacement/conversion took less than 2 hours and now the garage door purrs like it was newly installed yesterday!
I would definitely recommend NOVA Garage Door Services to anybody that has garage door problems!
