What Clients Say
Excellent customer service! We just had a new water softener installed a few days ago. Andy was quick, quiet, and friendly while working in our basement. He explained everything very clearly, and was very knowledgeable about the softener and the company. He even went the extra mile and fixed a leaky pipe he noticed when first arriving, saving me at least a couple hundred dollars in the process. Crossing that additional fix off my list of home projects made my week, sad as that may be. Cody, the owner, has also been very pleasant to work with. He did a free home water test, making sure to ask lots of questions, and test both the hard and soft water to know which unit would take on our well water the best. He’s worked patiently with us to make sure we feel well cared for after two years of struggling with high iron, and dishonest deals. We’re glad to have found a company that guarantees the units they install and the work they do.
