Quality, ingenuity, sustainability licensed and insured home remodeling specialist. We focus on providing our clients with the best construction experience. Give us a call today and we promise to take care of you!

"What a project! The initial plan to expand our lake house and add a level turned into a total rebuild due to discovery of standing water and rot. This project landed during the COVID pandemic and met with some unavoidable delays. Throughout the project my husband and I met with Matt and Steve regularly (weekly). Matt was always organized providing a list of items we needed to discuss, decisions that needed to be made and timelines for next steps. Matt and Steve consistently offered many ideas for ways to achieve what was important to us (kitchen layout with view to lake, beverage area, ample work surface, closed laundry area etc.), finish options (siding, roofing), lighting options etc. Though the project took longer than planned (thank you COVID), the result is a beautiful, comfortable home. We are very happy with the end result!"

"Brian took phenomenal care of us throughout the planning, building, and finishing stages. He kept the project on budget and moving along with constant communication. It was clear the whole time how much personal pride Brian and his team take in their work and in customer satisfaction. Another wrinkle is that I work from home. The Dinse Contacting team were respectful and cognizant of that fact and took great pains not to disturb me. The work itself: Brian and the team redid my entire finished basement, adding a full bathroom and moving walls around. They dug a new egress well and put a larger window into the bedroom. The bathroom is a work of art. The entire level is now the nicest floor of my house (and the main floor isn’t too shabby). When the time comes to start doing work on the main floor, there’s only one company I’d trust to do the work, and that’s Dinse Contracting. They hung mirrors in my gym, laid amazing tile in the bathroom, built gorgeous workbenches in my workshop, and on and on. Final notes: redid the awful electrical they encountered when they opened up the walls; insulated the exterior and interior walls; laid flooring and underlayment; built a custom handrail that complements the design of the level; amazing trim work; bright and beautiful lighting; hung doors (even ones that had to be shortened) that swing effortlessly. Truly, I could not be happier. Great company, great leader (Brian Dinse), and incredible finished product. You’ll get the white glove treatment from the first meeting to the last item on the punch list. Thank me later. You won’t be disappointed."

"Wolverine Contracting Design + Remodel provided us with exceptional craftsmanship for our renovation. They weren’t our cheapest option but their unique cost-plus process of contracting, clear & transparent labor rates and discounts saved us thousands on our projects. We have never seen a company operate in this manner, but it just made complete sense to us, and it works extremely well. Along the way we were a bit indecisive and made a few changes which added work to the original scope, increased our budget and timeline, however Douglas immediately shifted into another gear and was able to incorporate our changes within the original design. He is extremely honest, trustworthy and knowledgeable of his trade. His communication skills and integrity were second to none. I don’t know how he handles all the stress, but he makes it look easy. All team members and subcontractors were respectful of us and our home and a pleasure to work with as well. We highly recommend Wolverine Contracting and will be contacting them for any future projects."

FAQs for addition to existing structure building service projects in Chelsea, MI

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.
