DPG Home Improvement LLC.

DPG Home Improvement is a two-person Melrose, MA outfit that installs replacement and custom windows plus vinyl siding across Greater Boston and the North Shore, run by owner Dennis Grynkiewicz, who -- according to the company's own site -- built and sold houses in Florida for five-plus years before starting the business in 2014. Its Massachusetts home improvement contractor registration is active. The written record here is thin and mostly older: in a 2020 Google review, a customer had two interior doors installed and needed the exterior doors taken off and reinstalled, coming away saying they fit better than the original install. Beyond that one write-up, the number side leans strongly positive -- Porch shows 5.0 from 17 ratings (though none of the review text is shown) and BBB rates the company A+, though it is not BBB-accredited. One thing worth asking about directly: DPG's own Houzz profile, after describing its window and siding work, ends by telling readers to contact 'Window Depot Boston' -- a different brand name -- so it's worth confirming how the two are related before booking through that listing. For window replacement or siding work in the Melrose/North Shore area from a licensed, small local operator, this is a reasonable call -- just clarify which name to book under.
