I'm not one to write reviews, but I had to give David a huge THANKS! I called him this morning, SUNDAY, April, 30, 2017. He came right out and evaluated my situation. My spring was broken and my rollers were heavily worn. he performed the install of new, more heavy duty springs and ball bearing rollers. He also performed a tuneup. My garage door opens smoother and more quiet than when it was new. He did all this without charging me a SUNDAY call. All the other places I called wanted to charge me a hefty fee to come out on SUNDAY. The pricing was also lower than anyone else. He totally went above and beyond. I will use David for all future work and recommend him highly to everyone.
