Serving Mukwonago Families Since 1956

Family-owned means we’re exceptionally committed to assisting yours

Martens Plumbing & Heating offers the highest quality home comfort services in the Mukwonago area at affordable, competitive rates. Our three generations of family-owned, family-run service, and 60 years of experience in the heating, ventilation, and air conditioning industry make us extraordinarily qualified to serve customers. Our primary goal is to provide solutions of the highest quality to meet all heating, cooling, and plumbing needs, so our valued customers and neighbors receive the best value for their money. When you work with Martens Plumbing, you know you are receiving superior products and service. Our certified technicians use state-of-the-art technology for installations as well as for diagnosing and repairing existing problems. Whether you’re dealing with an emergency, tackling a small repair job, or building a new home, we can help.

Family first for your convenience

Like most of life’s problems, issues don’t happen on a 9 to 5 schedule. In fact, many plumbing issues are discovered late at night. We take a family-first approach to business which is why we’re always available to answer calls, respond 24/7 to emergencies, and meet your needs with furnace and air conditioner installation, repair, and maintenance. We understand unexpected crises, and we have a live dispatcher ready to go at all times. We work on your schedule.

How we’re different

As a family-owned business, we are committed to our customers’ satisfaction. We want them to be completely satisfied with all of our services. As a result, we offer services that are hard-to-find—including responding to plumbing emergencies at 2 a.m. When you call, a “live person” will assess the situation and dispatch the proper technician to fix it. In addition to heating and cooling, Martens Plumbing & Heating is one of the only area businesses delivering full-service plumbing along with expert bathroom and kitchen remodeling. No matter what issue you’re facing, we can resolve it quickly and expertly with complete plumbing, sewer and piping, and water treatment services. From remodeling your bathroom to testing your water, you can expect exceptional service, start to finish, from certified technicians and licensed plumbers.

Right here and right for you

Three generations earning your trust. A fully insured, licensed, bonded, and personable staff. A guarantee of complete customer satisfaction. And fast, right-away service at competitive, reasonable rates. Whether your needs are big or small, simple or complex, we’re ready to help. Simply put, Martens Plumbing & Heating is right here.
