Managing multiple subcontractors creates coordination chaos and schedule risk. QBC is a multi-scope commercial subcontractor serving developers, general contractors, and property managers across Wisconsin and Northern Illinois. We bundle rough carpentry, finish carpentry, cabinetry, countertops, flooring, and materials supply under one contract, eliminating finger-pointing, reducing schedule slippage, and protecting your profit margins. One partner. One schedule. Zero headaches.
Our carpentry and installation crews serve Dane County and surrounding Wisconsin counties, including Madison, Milwaukee, and Fox Valley metro areas. For building materials, we support all of Wisconsin and Northern Illinois.
Most developers and general contractors deal with the same recurring nightmare: juggling five different subs, each with their own schedule, each pointing fingers when something goes wrong. Your schedule slips. Your budget bleeds. Your reputation takes the hit.
What We Provide:
• Rough carpentry and framing
• Finish carpentry and trim
• Cabinetry and countertops
• Flooring installation
• Building materials supply
QBC eliminates the chaos by bundling your labor and materials under one contract, one schedule, and one point of accountability.

Brains: 25+ years of experience planning, sourcing, and executing complex commercial projects. We've handled everything from 450-unit multi-family developments to large-scale tenant improvements, and we bring that knowledge to your project.
Muscle: Field crews who show up on time, follow the plan, and take pride in their work. Every person on our team understands that your reputation depends on our execution. That's why quality and reliability aren't negotiable.
Materials: High-volume pricing on everything from framing lumber and trusses to cabinetry, countertops, and finishes, delivered on your schedule. Transparent pricing, no markup games, because we supply and install.
The Bottom Line: No BS. QBC is the reliable construction partner who knows when to step in and how to finish the job.

QBC was founded in 1998 with a "get it done" mentality. Four friends started in a Madison living room with a beat-up pickup truck, sitting on a couch waiting for the phone to ring. We built our reputation one project at a time through reliable execution and honest communication.
That approach worked. As a result, we've grown into one of the leading multi-scope subcontractors in Wisconsin, handling projects ranging from $50,000 tenant rehabs to $115M+ multi-family developments.
