I had All-N-1 install my sprinkler system about 5 years ago and from day one had nothing but problems. The first day it was installed a pipe broke in the ground flooding my yard and they had to completely tear up my yard to fix the broken pipe. Also they installed a system that they apparently had never used before and didn't tell me this until afterwards. Every time I had to deal with them I was charged more than I was quoted and when it finally broke down they had to install a whole new system because the parts needed to fix the system were discontinued. I would not recommend using them unless you want to deal with headache after headache.
