Michael A Guimaraes Construction

Ten permits, and almost every one is ductwork. Michael A Guimaraes works out of 11 Vandine St in Wilmington, and the permitted jobs on file are the sheet-metal side of heating and cooling: air handlers, duct runs, split systems, exhaust venting. The specifics span 2009 to 2018. Two Trane air handlers with an ERV and full duct runs in Milton in 2018, a $50,000 job. A hydronic air handler on a fourth floor and attic in West Newton in 2014, with sheet metal through the house and kitchen and bath exhaust. A steady run of Brookline residential mechanical permits between 2009 and 2017 — hot-air furnaces, split air conditioning, a basement air handler — mostly in the $6,000 to $28,000 range. Two odd ones out, a balcony roof repair and porch brick work in Brockton, date to 2008 and 2009. Licensing is where a homeowner should slow down. BuildZoom lists a Massachusetts Sheet Metal and Sheet Metal Business licence as active, checked in August 2025 and April 2026 — but shows no number for either. It also marks a construction supervisor licence (#CS-084920) and two home improvement contractor registrations (#194048 and #138418) as inactive. Those are the directory's records, not a state registry check, and the two categories carry different weight: sheet-metal work is the trade the permits actually show. No customer has written about this outfit anywhere found. If you want ducted air conditioning or a furnace-and-duct job in the Brookline-Newton-Wilmington belt, the permitted history is genuine and specific. Ask for the sheet-metal licence number and current registration status in writing, and for two or three recent job addresses, before you commit.
