DAG General Construction

DAG General Construction is a Boston general contractor led by CEO Daniel Alvarenga, offering renovation, waterproofing, concrete, flooring and painting work, by its own account, across the Boston area. The company says it's been in business 20 years, though its written review record is recent and short — eight reviews, all five-star, dating from late 2024 through mid-2026. The reviews are consistently positive but mostly brief, praising the crew's professionalism, organization and work ethic without describing specific jobs in much detail. One reviewer named Daniel and a colleague, Joseph, and described a project in Dorchester; several describe a clean job site and dependable follow-through. The company's Massachusetts home improvement contractor registration is active. With a limited public review history, it's worth asking for references or examples from past work when getting a quote.
