There are a lot of contracting companies to choose from in the greater Milwaukee and Lake Country area. Just like any industry, there are some great options and some that may not meet your standards. We believe there are a few things that set us apart from the rest. We specialize in customization – building things from scratch to meet our clients’ specific needs. We do not use prefabricated frames or materials. We do things the traditional way and only use the best materials and contractors. We do not have any sales people or expediters on our staff – when you work with Renz Construction, you work directly with owners Greg and Wendy. Read through our history to learn more about Renz Construction, meet our team to see who you will be working with, or read on to find out more about what sets us apart from the rest!


Older homes tend to have layouts that were once functional, but with today’s appliances, furniture, and electronics, what was once cozy and simple is now cramped and complicated. Renz Construction can open up living rooms to fit giant sectionals, fireplaces, and large beautiful windows while adding additional electrical for all your entertainment needs. We can update the flow of your kitchen so your dishwasher door can open all the way and you can run your garbage disposal and microwave at the same time without tripping a circuit. We can expand bedrooms to accommodate kingsize beds and update bathrooms to give you that soaking tub you deserve. The possibilities are limitless. Look at some of our services below and start planning today!


After 10 years in the business, working primarily on Lake Country homes, Renz Construction has learned a thing or two about vendors and subcontractors. The Renz team goes through a strict vetting process when selecting other contractors and will only work with the best our area has to offer. We have worked closely with many of our contracting partners for years and tackle each project as a unified team.

We source our construction materials in the same way. We know which brands hold up and which can cause problems down the road. After all, remodeling or building your new home is about so much more than a beautiful finished product – it needs to be safe and reliable for years to come.






Many of our clients live in other areas and those who do not, have very busy lives. We know our clients cannot be at the work site overseeing every detail of the project and we don’t expect them to. Wendy and Greg do regular walk-throughs of each project, keeping detailed notes and photos of every step in the process to keep their clients as up-to-date as they want to be, whether they are just down the road, or 1,000 miles away.

We know the remodeling and new construction process can come with some unexpected challenges. We promise to always look for the best solutions. We notify our clients immediately if there are any setbacks and have honest conversations on how to proceed. We believe in transparency and we will always tell you what is happening and the best way to proceed.

We are here to help you every step of the way. We will answer every question you have and address any concerns that may come up. We pride ourselves on being honest and open with our clients. In fact, we only take on a limited number of projects at once to ensure we provide the highest quality of service to our clients.


Remodeling your home can be quite the endeavor – new additions, updated kitchens, expanded bathrooms – they can take some time and they can certainly get a little messy. We believe, however, that our clients deserve to come home to a stress-free environment and that’s why we clean the work site every day before leaving. We even bring in professional cleaning services after key milestones in the construction process, like post-drywall. We take great precaution to ensure the area is safe from hazards and leave the site as clean as possible.
