*On the figures below: these are estimated ranges for this kind of work, not quotes from Mad City Windows & Baths. We do not hold published pricing for most companies. Where we do, it is shown as theirs and labeled. Your quote depends on your home, your scope and your market: see how we build these ranges.
Windows typical range for this work: $400–$950/window installed: Mad City focuses on triple-pane vinyl windows optimized for cold-climate energy performance. Their core product delivers U-factors in the 0.22–0.28 range, meaningfully better than entry-level double-pane alternatives and directly comparable to higher-priced specialty brands.
Bath replacement typical range for this work: $5,500–$14,000: One-day acrylic bath and shower installations. Custom-measured acrylic panels, grab bars, and accessibility conversions. Walk-in shower conversions and tub-to-shower conversions are a specialty.
Sales process: In-home consultation with measurement and same-day pricing. Mad City’s sales culture is consumer-friendly vs. the high-pressure model common in the replacement window industry. Their volume of reviews reflects a high level of referral business.
Installation: In-house crews. Window installations typically complete in 1 day. Bath installations are true one-day projects for standard acrylic conversions. Complex accessibility projects may take 2 days.
Warranty: Lifetime workmanship warranty on window installations. Bath systems carry manufacturer warranty plus Mad City’s labor coverage.
Best fit: Wisconsin, Minnesota, and northern Illinois homeowners who want regionally specialized window replacement with proven cold-climate performance. Also strong for upper Midwest homeowners who want a combined window + bath project through one company.
Consider alternatives if: You are outside their coverage area, or if you want a full custom tile bathroom remodel (Mad City’s bath division handles acrylic systems only).
