# MDH Construction **Trade:** General Contractor / Remodeling · **Address:** 186 S Meadow Rd #2, Plymouth, MA 02360, USA · **Phone:** (508) 682-5599 · **Website:** https://www.mdhconstruction.com/?utm_source=google&utm_medium=organic&utm_campaign=gbp&utm_content=plymouth-ma · **Languages:** English **Rating: 2.9/5** (low confidence) — from 4 reviews across 3 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low. ## The honest read MDH Construction, based in Plymouth, works in two lanes that show up across its Google reviews: MassSave-program attic insulation and air sealing, and broader home renovation. In a 2021 review, a homeowner who had used the company once before for MassSave attic work called again years later over attic condensation — Michael M from MDH came out, spent time walking through ventilation options, and helped compare choices in a way other contractors approached weren't willing to. A 2020 review describes a five-person crew completing an attic insulation job efficiently, with the homeowner noting the house felt noticeably warmer afterward, and a second 2020 review describes added attic insulation and new vents as professional, solid work. A 2018 review describes a full home renovation finished on budget with no surprises, led by an owner named Matt who stayed reachable by phone throughout the project. The written record on file runs from 2018 to 2021 and hasn't grown since — worth knowing going in. The company's Massachusetts home improvement contractor registration (#170721) shows expired in the state registry, so it is worth asking directly about its current registration status before signing anything. For attic insulation and air-sealing work tied to the MassSave program, or a full renovation, the handful of reviews on file describe attentive, on-budget work. **Strengths:** - Repeat customer — homeowner called them again years after first job - Attic insulation — MassSave program work praised across several reviews - Full renovation — finished on budget with no cost surprises - Responsive owner — Matt answered calls and explained options throughout **Concerns:** - Lapsed license — Massachusetts HIC registration is now expired ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - A 2021 review describes a repeat customer calling MDH back years after a first MassSave job _(confidence: medium)_ - [Google Reviews](https://maps.google.com/?cid=1822779321272037188&g_mp=CiVnb29nbGUubWFwcy5wbGFjZXMudjEuUGxhY2VzLkdldFBsYWNlEAIYBCAA) — “5★ I had previously used MDH for some MassSave attic and home sealing services.
