G.M. Roth Design Remodeling

G.M. Roth Design Remodeling is a design-build remodeling firm based in Nashua, NH, holding an active Massachusetts home improvement contractor registration verified with the state registry, plus an A+, accredited Better Business Bureau profile. The review record here is deep and spans a decade — 69 reviews from 2016 through 2026 across eight platforms, including a perfect 5.0 on Houzz. Customers describe full-scale kitchen, bathroom, and whole-floor remodels, additions, deck construction, and structural work like removing load-bearing walls, with an in-house team spanning design, project management, and skilled trades. Several reviewers specifically praise accessibility work — installing a home elevator and a roll-in shower for a client using a wheelchair, and building bathrooms to help older homeowners age in place safely. A number of customers describe returning for multiple projects over many years, including one relationship going back to 1992 and another describing a third project completed in the past decade, and several credit the company's design process, clean job sites, and clear scheduling for the smooth experience. That said, the record includes real complaints worth knowing about. A review from earlier this year described feeling ignored after two unreturned messages, along with a pricing quote that felt very high before materials were even chosen. An older review, from 2022, alleged that a senior sales manager gave conflicting explanations about whether management was aware of ongoing project issues. And a review from late 2025 described feeling uncomfortable with the company's culture and included a serious, unverified allegation of inappropriate physical conduct by someone in upper management — a claim that hasn't been corroborated elsewhere in the record but is serious enough to flag directly. Weighed against dozens of detailed, specific, multi-year accounts of high-quality remodeling work, these are a minority, but a homeowner should know about both sides before engaging a company for a major renovation. For substantial remodeling — kitchens, bathrooms, additions, or accessibility modifications — the depth of positive evidence here is considerable, alongside real complaints worth asking about directly.
