We hired them based on their Angie's List reviews also. A great experience. Got a quote before they even left when they came out to look at our house. They were able to get it scheduled very quickly and always showed up on time, left the yard very clean at the end of the day, and were also very considerate when my wife had to take the dogs out to use the yard.
This was 18 months ago, and the house still looks great. The owner just emailed me to tell me the warranty was half way up and to let him know if any issues has arisen.
I'd highly recommend this company. The pricing was in line with the market and the experience was great.
