"We had our whole house water filter system upgraded / replaced. The work was fast, effective and not overly priced. Justin was great and went the extra mile for us. Would recommend and hire them again."

"Outstanding analysis and advice, timely service fairly priced, and outstanding workmanship--Who could ask for anything more from a Well Service company? Over the years I've spent nearly two decades in property management and maintenance, and in construction, and have seen the quality of workmanship decline. Mad River is a throwback to when craftsmen took pride in their work."

"Amilcar was professional from the start to the finish. He was efficient too. He was very neat and kept the work area clean. I will certainly call on Diamond Plumbing and Heating again should I need service of the type they provide"
