"I have used JM for a number of projects from Roofing to Concrete floor in garage. I learned long ago that you get what you pay for. JM might not be the cheapest contractor but the quality of the work is second to none. They put a new staircase outside the front of my home that has 12 steps with railings and I will get many years out of that it is so sturdy and looks fantastic. My home is very old and can be hard to work on but it didn't matter what I asked them to do, they found a way. I will pay a premium for work done at this level."

We are Smith Brothers Renovations LLC (Formerly Hilbert Company), We are a small family business (my brother and I) specializing in Kitchen / Bath remodeling and home additions. Our showroom and Custom cabinet shop are located in Slinger. We do everything from supplying high quality custom cabinets to complete turn key remodeling including design. We have been contractors in the remodeling business for over 30 years. Our work is excellent, and if you hire us, you can know that one or both of us will be the one actually providing the craftsmanship for your project. We aim to provide very high quality workmanship at a very competitive price. We do not have a sales staff, office managers, or an advertising budget. Our overhead is kept low, and we are able to often times complete a project for half of what the large companies tell you that you “should be spending”.

"Loved working with Hilbert Co. They provided excellent work at a fair price. Communication was outstanding and our remodeled bathroom turned out spectacular! Thanks so much Corey & Mitch for all the care you took on our project. You didn’t miss a detail. Well, maybe one, but it was corrected without issue. I will hire them again and my family & friends have already asked “who did your remodel?” Wished every company was like this one!"

FAQs for addition to existing structure building service projects in Waukesha, WI

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
