"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!"
