I've used them in the past for both chip repairs and windshield replacements. My experiences were excellent...until recently.
A rock flew into my windshield and chipped it. It also spidered out probably to the size of a quarter or a little more. I spoke to Brian and he said he would have a technician come to my house to attempt a repair. The technician came out the next day...a Friday at 5:30...looked at it and left his card under the wiper with a note saying the chip was larger than a 50-cent piece and not repairable. He didn't even have the courtesy to knock on the door to talk to me or my husband face-to-face. I called Brian on Monday to see if he could explain how it's not repairable, so he said to bring the car into their shop. When I got into the car the chip had an 8-inch crack splintered off it so I knew at this point it wouldn't be repairable. He quoted me a replacement cost that was about $75 more than who I ended up going with.
Long story short, I will never go back to Deals again. What probably would've cost me $50 to repair ended up costing me over 4 times that amount because somebody didn't want to work so late on a Friday afternoon.
