"We had a terible drain clog and had backups coming into our toilet and shower. We called Diamond House Plumbing and they sent Jeff out right away. He was able to clear the blockage, pulling out many roots and blasting our lines clear with a very impresive water hydro-jet system. I would highly recomend Diamond House Plumbing to my friends and family and anyone in need of professinal plumbing services. Thank you!"

"I actually had the following things done to my home as I was only allowed to choose 1 item: 1st Class removed all galvanized & repiped using Pex for new Halo filtration. (I am a camper) And, the street pipe was replaced too. Yay! Replaced toilet. The price they gave was righteous because new drywall needed to be done also. The team worked so diligently and were so faithful. My props go to Tito, Manny, Ricky, Moses and Anthony. Well done guys, well done!"
