I've used Armstrong twice now. First for a busted water heater and then again when I needed all the pipes in my house replaced. As a single woman, with a much older home, I was more then a little overwhelmed at first when I had to replace the pipes. They did an amazing job at very reasonable rates and everyone I encountered from the office employees to the two guys who sweated it out around and under my house for days in 100 degree weather were all very professional and efficient. It's been a month since they did the job and the water pressure in my home is amazing now!
