Sigma Pros,LLC

Sigma Pros works on other people's buildings more than other people's houses. From 910 Main Street in Wakefield, the company says it has been renovating occupied apartment communities, lobbies and common areas, and commercial properties since 2004 — 22 years by its own count — with an in-house shop turning out cabinets, millwork, and aluminum and PVC doors and windows through a supply partnership it names with TESTERAL. The written history is short and it is old. Two Google reviews, both brief and both warm: a 2018 customer called them a patient and dedicated group of professionals, and a 2019 one called them awesome and kind. Google's page carries 5 stars across 10 ratings, and the company appears in the Wakefield Area Chamber directory. The written trail ends in 2019. So settle the fit question first. A homeowner planning a kitchen or a bath is not this company's usual client; property managers, condo boards and developers are. If your project is a building rather than a room — a run of unit turns, a lobby, a batch of custom cabinet doors — ask for references from recent work of that shape, since nothing has been written publicly about their jobs in years.
