A D Construction LLC

A D Construction is a family-owned Boston design/build general contractor based in the South End, founded by Alex Tsalagas and operating since 1988 — a long local history its own site and its Houzz profile's awards both point to. The clearest signal here is repeat business: one reviewer, writing in 2023, described using Alex and his team "several times," most notably a week-long sprint to get a newly closed condo ready to move into on schedule. Another, in a 2025 review, described a six-year relationship, crediting Alex and David for honest, cost-effective problem-solving through a full home renovation and for staying patient through requests and changes. The record beyond individual reviews runs deep: the company holds an active Massachusetts Home Improvement Contractor license verified against the state registry, has been a BBB-accredited A+ business since 2008, and its Houzz profile lists a run of awards spanning nearly a decade — Boston's Best General Contractor (2013-2020), Best of Massachusetts Deck Builders (2016-2021), and multiple Houzz service and design awards. The written record on file runs from 2023 to 2025, and Google separately shows ratings in the high 4s, with Houzz showing a perfect 5.0★ across 17 reviews. There isn't a real downside to flag here — the record is consistent and long-running. As with any bigger renovation, confirm scope and timeline directly for your project. A D Construction is a solid pick for a full home renovation, addition, or new construction project in the Boston area, backed by a genuinely long track record and a verified license.
