Absolute General Contracting is a Milton, MA general contractor founded in 2000 by Kieran McKinney and Gary MacDonald, who still co-own and run the company today, according to its site. It describes itself as full-service — additions, kitchens, finish carpentry, structural repairs, disaster restoration and facilities maintenance — working for homeowners, developers and investors around Boston. In a December 2015 review, a homeowner described adding a master bedroom, bathroom and family room, reaching Kieran by email and getting a callback and home visit the same day; the crew is described as dependable, timely and respectful, and the homeowner's own plumber and electrician commented that it was some of the best work they'd seen. A May 2013 review from a repeat customer said Kieran had handled many projects for their family over the years and had recommended the company to others. In 2016, a local news site reported the company was frequently recommended on Milton's neighborhood Facebook group as a go-to general contractor. BuildZoom's permit records show 53 projects, almost entirely residential — kitchen and bathroom remodels, additions, window replacements, and new single- and multi-family construction — around Milton and nearby towns, plus one commercial permit for a retail space in Randolph. BuildZoom gives it a score of 96, which it says puts the company in the top 20% of Massachusetts contractors, and lists a Home Improvement Contractor license for the business. A strong call for an addition or a bigger remodel where you want one contractor coordinating the whole job; confirm the license number directly with the state and ask for references from a recent, similar-scope project.

We contacted Kieran via email and received a call back and a home visit in the same day. We are adding on a master bed and bath as well as a family room. Kieran and his co-workers have been dependable, timely and respectful. We had our own plumber and electrician for the renovation/addition and both commented that the work of Absolute is some of the best they have seen.
