Hammes Company — General Contractor in Madison, Wisconsin

How does a Madison-based general contractor coordinate all the trades for a seamless renovation?

• Detailed preconstruction planning that aligns scope, budget, and schedule.
• Sequenced trade workflows for carpentry, electrical, plumbing, roofing, and finishes.
• Owner’s-representative rigor borrowed from complex civic projects.

Hammes Company operates as a general contractor and real estate developer in Madison, bringing the same disciplined oversight it used as project developer for the University of Wisconsin’s Kohl Center, which opened in 1998. Their team builds week-by-week schedules, holds trade coordination meetings, and front-loads permitting so inspections align with milestones rather than slowing the job. Longstanding ties with the Building Trades Council of South Central Wisconsin, highlighted in a 2010 announcement, help them source skilled labor and maintain jobsite safety. Experience serving as an owner’s representative for public authorities—such as the 2016 extension with the MSFA—translates into clear documentation, punch-list control, and transparent cost tracking at the residential level. For homeowners, that means fewer surprises: subs arrive when materials are ready, change orders are documented, and cleanup plus neighbor notifications are baked into the plan.

What is the process for room additions and second-story expansions on Madison homes?

Hammes begins Room additions and second-story expansions with a feasibility review of the existing structure—foundation capacity, load paths, rooflines, and stair placement—followed by zoning checks for setbacks and height under City of Madison rules. The team prepares schematic options to visualize massing and daylight, then refines to permit-ready drawings and an itemized budget. Field-measured tie-ins ensure the new work matches floor elevations and wall planes, while exterior selections mirror siding, brick, and trim profiles so the addition feels original to the home. Mechanical, electrical, and plumbing are coordinated early to confirm panel capacity, duct routing, and plumbing venting before framing starts. During construction, Hammes sequences framers, roofers, and insulators to close the envelope quickly, reducing exposure and keeping living areas usable; they then phase interior work to minimize downtime and streamline inspections through final occupancy.

Can a sunroom or enclosed patio be built to feel integrated with the existing house?

Yes—Hammes treats Sunroom and enclosed patio construction as extensions of the home, not bolt-ons. Early design explores four-season versus three-season performance, evaluating insulation levels, thermal breaks, and low-e glazing to manage winter heat loss and summer gain. Foundations are engineered to support glass loads and roof snow, while transitions at doors, thresholds, and flooring are detailed to avoid step-downs or awkward trim. They often propose radiant floor heat and discreet shading to make the space comfortable without overtaxing the main HVAC system. Orientation studies guide window placement for light without glare, and roof tie-ins are flashed to manufacturer specs to protect the existing envelope. With permit sets that include structural details and energy compliance, the team sequences framers and window installers first, then electricians for lighting and outlets, and finish carpenters for millwork that matches the rest of the house.
