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!"

We are a locally owned and operated basement finishing specialist servicing the Chicagoland area. Our focus is providing clients with a clear, upfront vision of expectations through a design/build approach. Our free design service provides potential customers with a collaborative consultation geared towards budget, wants, needs and lifestyle.

"After spending a good amount with a different contractor to remodel our main floor, we had to settle with the fact that a basement remodel was likely not in our short term plans. However, after taking a meeting with Matrix, we were pleasantly surprised that a substantial remodel was not out of the question after all. We were honestly so focused on the fact that something could get done that we didn’t nit pick on the finishes and some of the details, but wow were we impressed by the quality and workmanship of the end product. The project managers (we had Ben) do everything that’s needed to keep on schedule, but rest assured this does not mean that any shortcuts of any kind are taken. The sub-contractors used are simply amazing, and seem motivated to do whatever is needed to keep Matrix and the customers happy. Overall, we couldn’t be more pleased with how everything turned out!"

FAQs for addition to existing structure building service projects in Wauwatosa, 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.
