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!"

CWE Renovations is ready to turn your project into a reality - no dream is out of reach! Our team of expert remodelers will give a thorough assessment & estimate for your project. Call today to get on our schedule!

"Our experience with CWE Renovations has been marked by a troubling lack of professionalism, accountability, and customer service. Despite having a comprehensive record of issues spanning nine pages, we will have to summarize the key points here to provide a clear picture of why we strongly advise against using this contractor. Project Timeline and Delays: We were initially given an estimated completion timeline of approximately 12 weeks for our basement renovation. Contrary to this, the project has now extended well beyond 18 weeks. We were assured on two separate occasions (6/27 and 7/11) that only two weeks of work remained. Unfortunately, scheduling has been disorganized, with no clear plan to ensure tasks are completed consecutively. For instance, the electrician's work remains pending with no definitive schedule, and the carpet installation, scheduled for August 19th, was delayed due to the contractor's failure to arrange for measurement until July 26th (despite us inquiring about this since 6/27). Communication and Accountability Issues: Our attempts to gather accurate information and resolve issues have gone ignored. We discovered discrepancies when we contacted Waste Management regarding the pickup of our bagsters, only to find no record of an order. Additionally, a metal rack has been left for 2.5 weeks in our driveway due to the contractor's failure to follow up with Home Depot immediately upon it being left behind by mistake. More concerning, we found that the electrician listed on our permit had no involvement with our project. Upon investigation, we learned that the permit was improperly filed under a business' name, and the electrician ,who worked for the business, was only working on our project as a side job, potentially jeopardizing their professional standing. Overall Experience: The most disappointing aspect has been the lack of communication and ownership. We are left with an incomplete basement and are now seeking a refund for the portions of the project that have not been completed as promised. Given these significant issues, we strongly recommend avoiding CWE Renovations for any renovation projects. Our experience underscores serious concerns regarding their reliability and commitment to customer satisfaction. Everything incomplete as 8/12 (18 weeks after the start date with a 12 week estimate): Electrician to finish outlets, lights, light switches, etc (no eta) â we paid for on 7/30 Carpet Installed (given a date of 8/19 which is completely unacceptable when we have been asking about this since 6/27) we paid for on 7/30 requesting this refunded since Carpet Installation Guy does not want to work with Dan and quoted us almost half to install Trim completed around stairs and in bathroom - Paid Metal Rack Removed from Doors (Offered to reach out myself since Dan doesn't seem to have any urgency in it) -Requesting Dan cover the cost to remove on 8/15 Garbage Removed (two bagsters) We paid for on 2/26 Door Installed over the breaker box Lien Waivers from Plumber, HVAC, Electrician Railing on the stairs (which we have made clear we do not want this in until carpet is installed so we can get our couch downstairs) Paid on 4/12 invoice"

Addition to existing structure building services FAQs

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.
