Some Words From Our Clients

Billy from Diamond ITR has been our plumber for over 10 years and they have always done an amazing job. I highly recommend them!

Bradley L, Bethpage Hotel

Diamond ITR did an amazing job! We had a major leak in our kitchen and only had a week to before our Grand Opening. They were efficient, clean and affordable! Will use again!
