Darin was rarely able to answer the phone when I called, but always returned my call within an hour or so. He was very polite when he came to do the estimate and actually called me to say he could show up early. Anyone who has worked with contractors knows how rare that is. His price was well below all the others we had received. When we called him back to hire him, he said they were scheduling about 3 weeks out and he would give me a call when we were next. Three weeks later I called him to see how close we were to the top of his list and he said that the rainy weather had put him a little behind schedule. This was understandable since we had a really wet spring, but I wish he had called me to let me know. He offered to do the indoor work the next day since the forecast was for more rain. I took the day off and he arrived with his plumber bright and early. Both of them were very professional and were no inconvenience. When he was done, the plumber showed me everything and walked me through what he had done. Darin called me back a week later when the weather was nice again and we set up an install day. Just like last time, I took a day off, he showed up first thing in the morning with a couple helpers and went right to work. With the exception of letting them into the house, I really didn't need to be there. They just did their thing while I read a book inside. It took them most of the day and when they were done, Darin showed me how to use the control box. I cut him a check and that was it. That was 10 days ago and the sprinklers are working fine. I have a pretty flexible schedule, so taking 2 days off wasn't as much of a problem for me as it might be for some. You just have to be aware that installing a sprinkler system does require a lot of indoor work as well, so it's not something that they can do while you're at work. All in all the experience was good. You can barely tell where they ran the line. The sod they dug up around the sprinkler heads is starting to turn brown, but that's to be expected. I'm sure it'll come back next year, if not later this summer.
