About Massintransit

A Local Window Crew for Grand Rapids Homes

Massintransit replaces windows for homeowners across Grand Rapids, Michigan and the surrounding Kent County communities. We work with vinyl, fiberglass, and wood frames, fit them with low-E insulated glass, and install everything from a single foggy unit to a whole-home replacement. Full-frame jobs, insert pocket windows, egress openings, bay and bow units, and patio door swaps all run through the same local crew.

Grand Rapids has a deep stock of older homes, and we are right at home in them. A century-old house in Heritage Hill often has openings that have shifted over the decades, which is exactly why careful measuring matters. We template each rough opening for the real conditions, flash to IRC code, and seal the unit so the finished window holds tight through a Michigan January.

What Sets Us Apart

• Rooted in the 616. We work Grand Rapids neighborhoods every week and know the local housing stock street by street.
• Written quotes. We walk you through frame materials and glass packages, then put the price in writing before any work begins.
• Clean, code-correct installs. We protect your floors and landscaping, flash to code, and haul the old sashes away.
• Local and licensed. We are a licensed, insured Grand Rapids crew, and a real person answers when you call.
