The two young men were respectful of my house, they put plastic booties over their work boots,put tarps down to protect the floor and inside the vanity. The problem was solved in a very timely manner something the contractor that installed the new sinks and pipes couldn’t fix on 2 occasions. We have used Deluxe plumbing in the past and would recommend them and would use them in the future

I must admit I had a chip on my shoulder because Deluxe plumbing sold me an electric heat pump as a single source heating for my small range home. Well it is an awful system and while it heats the entire home it blows cold air half the time. Haller’s tech Akim K arrived and was fantastic he is extremely knowledgeable and professional! Hopefully the solution that will be priced will be fair and solve my issue.
