Established in 1985. Mendel Plumbing & Heating, Inc. was established with the intent of becoming the premier plumbing and heating company in the Fox Valley community. Decades ago, in a little garage in St. Charles, Mendel began combining its own brand of unmatched service with the best products available on the market. Since then, we have come to be known as the highest quality provider of repair, installation, new construction and renovation work in the Fox Valley area. If you live or work in St. Charles, Batavia or Geneva, you are most likely familiar with our famous blue trucks. We purchased the first one back in 1985 and our fleet has continued to grow ever since. You'll never see a dirty Mendel truck anywhere because we wash them every single day! Although we have come a long way from our modest beginnings in that small St. Charles garage, the integrity of our company and our team has remained intact. We still pride ourselves on providing an unmatched level of attention to each and every customer. Mendel Plumbing & Heating - The Company the Fox Valley Area Trusts
