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.

"We recently had our entire basement finished by Matrix Basements, and we couldn't be more thrilled with the results! The entire process was smooth, professional, and stayed right on schedule. Rodrigo, our carpenter, did incredible work. His craftsmanship and attention to detail really brought everything together beautifully. Ben, our project manager, was fantastic at keeping everything running seamlessly. He was always communicative and made sure we were in the loop every step of the way. The whole team was timely, professional, and clearly committed to delivering a high-quality result. We’re beyond pleased with how everything turned out and can’t wait to start using and enjoying our new space. Highly recommend Matrix Basements! "

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"

"The very best thing about Big Dave's is that he shows up when he says he will, he does the job we agreed on, and he cleans up after himself.

I'll have no other GC darken my doors ever again."

Addition to existing structure building services FAQs

Most ADU projects require several months from initial planning through final inspection. The timeline includes designing plans, securing permits, site preparation, construction, and finishing work. 

Factors affecting duration include project complexity, contractor availability, weather conditions, and local permitting processes. Planning for potential delays due to material shortages or inspection scheduling is advisable when establishing your project timeline.

Homeowners can access various funding sources for ADU projects. Home equity loans and lines of credit leverage existing property value, while construction loans provide phased funding specifically for building projects. Some areas offer specialized ADU financing programs with favorable terms. 

Personal loans might work for smaller conversions, though they often carry higher interest rates. Your financial situation, credit profile, and project scope will determine which option provides the most advantageous terms.

Adding an ADU often increases your property's assessed value, resulting in higher tax obligations. The specific impact varies by location, as assessment methods and tax rates differ between jurisdictions. Some areas offer temporary exemptions or gradual increases to ease the financial transition. 

For accurate projections, consult your local tax assessor before beginning construction to understand how your specific project will affect future tax bills.

Short-term rental regulations vary dramatically between municipalities. Some jurisdictions permit vacation rentals with minimal restrictions, while others impose occupancy limits, licensing requirements, or outright prohibitions, particularly for ADUs. Many areas require owner occupancy of the primary residence when renting an ADU short-term. 

Research your local ordinances thoroughly before planning rental income, as non-compliance penalties can be substantial.

The ADU construction process frequently encounters obstacles, including complex permitting requirements, unexpected site conditions requiring additional work, contractor scheduling difficulties, and budget management challenges. Many homeowners underestimate the complexity of coordinating multiple specialized trades. 

Additionally, ensuring adequate privacy between the main residence and ADU while maintaining aesthetic cohesion requires careful planning. Thorough preparation and working with experienced professionals can help navigate these common pitfalls.

Identifying qualified ADU contractors requires targeted research. Begin by seeking recommendations from neighbors with completed ADU projects or contacting local builder associations for specialist referrals. Review contractors' portfolios specifically for ADU or small residential projects similar to your vision. 

When interviewing potential candidates, assess their familiarity with local ADU regulations, ask about recent similar projects, and request contact information for past clients with comparable projects.
