About Mike
Mike founded remodelmath after researching window-replacement costs for his own home renovation and finding existing online calculators consistently 30–50% off the real quotes coming from contractors. The category was dominated by tools optimized for capturing leads rather than helping homeowners understand what their projects should actually cost.
Mike has overseen multiple home renovations as a homeowner and has hired general contractors at scale across personal and business projects. He brings methodology-driven discipline — public-data calibration, transparent assumption documentation, and explicit confidence bounds — to a category historically dominated by lead-gen funnels.
Outside of remodelmath, Mike is an entrepreneur and software founder who has built and operated products in adjacent categories. He writes the methodology, calibrates the cost data quarterly, and is recruiting industry contributors to expand the team.

On remodelmath
remodelmath is the project Mike writes for. The site publishes cost calculators for home-improvement projects, calibrated against real installer pricing and public construction-wage data. Every estimate the calculators produce is documented on a public methodology page — the goal is to give homeowners a credible reference to evaluate contractor quotes, not a lead-gen funnel that monetizes their visit.
