About Us

Six Decades of Responsive Customer Service and Pride in Our Family Profession

Founded by Ralph Martens in 1956 and passed on to his son, Jerry, and grandson, Jeff, family-owned and -operated Martens Plumbing & Heating has served friends and neighbors in Lake Country, Waukesha County, and Mukwonago areas for three generations. We offer on-budget, on-time heating, cooling, plumbing, and remodeling service—providing reasonable rates, free quotes, and professional specialists 24 hours a day. Our services have expanded and diversified, over the years in response to the needs of our customers. From your original consultation to your finished project, Martens Plumbing & Heating makes your experience as streamlined and simple as possible. You can count on a smooth, worry-free process, whether your job is small or complex. We have the experience to solve your problems.

Our Mission

Our mission and main focus can be summed up in four, simple words: urgency, integrity, response, and value. While others may focus on one or two of these, we consistently deliver on all four. They are key to our success and our customers’ satisfaction.

Our mission doesn’t end there. Our continued commitment to our customers’ needs is reflected in the training our staff receives, the products we carry, the manner in which we provide service, and, finally, in how we listen to our customers—better listening on our part helps us provide the service and products our customers appreciate. As a family-owned business, we understand how important it is to keep your family happy.

Our Competitive Edge

Like most problems, HVAC and plumbing issues don’t happen on a 9 to 5 schedule, which is why the Martens Plumbing & Heating team is on call for emergencies 24/7. A live person will always answer, and a team member will be in touch with you in a prompt, efficient manner.

We also offer full bath and kitchen remodeling services. Our plumbing expertise provided a natural expansion to complete bathroom and kitchen remodeling services. We are the experienced contractor you need to advise you on and install features like plumbing lines, fixtures, faucets, sinks, and toilets—whether your project is an upgrade or a total remodel. We can perform all the water and gas hookups—and make sure the work complies with local codes and regulations.

Window Shop in Our Showroom and Design Center

Visualizing your project before our work gets underway not only helps you compare products and materials, but also helps you understand what affects your budget. For that reason, we have a showroom and design center filled with bath and kitchen vignettes, where you can see colors, patterns, textures, designs, and more. We also have contacts with wholesaler design centers so our customers can window shop with a walk-through. Our customers know they can trust Martens Plumbing & Heating to take care of everything when it comes to plumbing remodeling.

A simple guarantee that our plumbers adhere to: We get the job done properly the first time around. Plumbing and heating problems should not persist, and we do not let them. Our Mukwonago-based team will fix your issue promptly and efficiently.
