"Unfortunately for my family, our Navien system was installed by inexperienced plumbers; which caused a huge flooding in our 1 year old brand new home. Thankfully we found Precise plumbing and not only was he able to arrive the same day we called, but he was able to resolve the issue, he educated us on what was the proper way of handling the system. We now have an experienced and knowledgeable company that we can trust and be upfront with us. When we asked if should have some work done in our home and my in-laws; he was honest and told us it wasn't necessary. That was enough proof for us that he cared about his clients and is not just about making a profit. We just wish the contractor hired them to install our two Navien units . We HIGHLY RECOMMEND Precise Plumbing & Heating Co."
