QC Building LLC Home Remodeling Contractor

QC Building LLC, doing business as QC Building Services, is a Roslindale-based general contractor that says it's been operating in Massachusetts since 2010. Reviewers across nearly a decade — Angi, Thumbtack, HomeAdvisor — consistently name the same person running the jobs: Wellington (spelled Welington in some older reviews), though the company's current site lists J.C. as owner and Welington G. in a civil-engineer role. The strongest, most repeated thread in the reviews is bathroom work — several homeowners from 2018 through 2022 describe full remodels done demo-to-finish, calling out a fair price and a design brought to life. One 2022 Thumbtack review lays out the range of one project: tiling, demolition, plumbing, fixture replacement and painting, done by a crew described as hard-working and quality-focused. An older 2018 review thanks the team for a porch-and-deck job and for keeping the schedule on track. The record isn't spotless. A 2015 review describes being charged $850 for a job and being unhappy with both the price and the communication, calling the experience a rip-off. A 2016 review of a window-replacement job was more measured — a fair result, but the crew seemed rushed toward the end. The company's own site lists several Massachusetts trade licenses — a Construction Supervisor license, a General Building Contractor license, a Drywall Contractor license, a C-33 Painting and Decorating Contractor license, plus plumbing and electrical work handled through licensed partners — but these are the company's own claims here, not confirmed against a state registry. Across 26 reviews going back to 2015, the volume and consistency are real, even if a handful of the accounts are dated. For a bathroom remodel or a multi-trade renovation in the Roslindale area, this is a crew with a long paper trail to check; it's worth asking directly about current licensing and getting a firm price before work starts, given the one pricing complaint on record.
