Here are some reviews from some of the customers that we serviced

Nora U - ⭐⭐⭐⭐⭐

I am so glad I found Tony! What a wealth of knowledge - he knows everything about rainwater collection and is the only person I trust to work on our system. He is honest, fair, and reliable. He answers all(there are many) of my questions with great patience. I highly, highly recommend him!

Jackie F -⭐⭐⭐⭐⭐

Tony saved us and many others during the SNOWMAGEDDON of 2021. Our rainwater system was shot. We didn't have water for a week, then when the pipes started to thaw, several burst. He was prompt, didn't mess around with what needed to be done and got us fixed up. Very reasonable, very understanding and we hope to use him in the future when we upgrade.

Dave G -⭐⭐⭐⭐⭐

Tony was very responsive and saved us after the snow-pocalypse when our rainwater pump was broken. He came prepared and met or exceeded the timelines he set for us. He was very good about explaining what and why he was doing things. I would definitely recommend his services.

Billy C -⭐⭐⭐⭐⭐

Tony is one of the best contractors I've ever had work on my house. He repaired our rain water system after the bad winter storm we had this year. He showed up when no one else would or could.
