DLM Remodeling

DLM Remodeling is the crew Waltham homeowners call when the windows are drafty or the siding needs replacing, and the numbers back that up: a 5.0 average across 35 Google ratings, with zero negative reviews in the last six months. The pattern that repeats review after review is the same — Brian, Steve, or Dave show up, work fast, and leave the site clean. David Merrifield started the business on his own in 1988; BBB lists it as 38 years in operation, and the company's own site says Merrifield and co-owner Steve Ventola have worked together for a decade. It's a small, owner-run outfit based at 101 Irving St in Waltham, and its site lists window replacement, siding, kitchen remodeling, and decks and porches among its services, covering towns from Waltham and Newton out to Andover and the North Shore. Windows are clearly the specialty. Recent Google reviews describe full-house jobs — 22 units replaced with new Harvey construction windows in one case, a full re-siding job in Woburn in another — with reviewers repeatedly calling out the crew's speed and the cleanup afterward. One March 2026 reviewer had a window turn out drafty after installation; DLM came back, pulled the panel, added insulation, and resealed it, and the reviewer still recommended the company afterward. It's a small enough sample that a single callback like that stands out, but it also shows they'll return to make it right. Beyond windows, a deck replacement and a sunroom remodel also show up in the recent review mix, both finished on the schedule the crew set. Kitchen remodeling is listed on the company's own site and turns up in an older, unrelated third-party mention from 2013, but there's little else to confirm it's a current focus — the last few years of reviews are almost entirely about windows and exterior work. Third-party sites back up the same read: Porch has it at 4.48 from 27 reviews, and BBB gives it an A+ grade, though DLM hasn't sought BBB accreditation itself. One smaller aggregator, Fresh Chalk, shows a thinner 80%-positive read from just five votes — the outlier in an otherwise consistent picture. Houzz, meanwhile, has no reviews at all yet, so don't expect a track record there. For a window job, a siding replacement, a deck, or a sunroom addition around Waltham or the North Shore, DLM's recent history is about as clean as it gets — just ask what happens if an install needs a follow-up fix, since at least one homeowner needed exactly that.
