What Our Customers Say
“Extremely helpful and communicative! Got our back flow tested and set us up on a yearly schedule so that the city is happy and we don't have to worry about it. Glad we called 1-A services!”

“They made my backflow test super simple. I just called and told them when I needed this test done by and they took care of the rest and sent the receipt to my email. I didn't have to do anything else after the initial phone call. They were very friendly and fairly priced as well.”
