JOHN'S COSTRUCTION

The most useful review of John's Construction opens with a refusal — someone else's. A homeowner with an 1890 slate roof on a three-story house wrote in July 2026 that this was the only company that would not turn the job down, and added that the crew stayed in OSHA compliance while climbing and walking the slate. That is roughly what people hire this Methuen outfit for: roofs other contractors pass on. In June 2026 a customer had them redo the roof of an 1800s house, take down a chimney, and reframe the soffits and fascia before wrapping them in aluminum — the crew, they said, worked their butts off getting it done. Another that month had a 25-year-old camp roof replaced and singled out the cleanup. Communication comes up again and again, in English and in Spanish. One May 2026 reviewer described clear communication and guaranteed, effective work. The Google page averages five stars across nine ratings. The caution here is arithmetic. Eight written reviews exist, every one of them posted in 2026, every one of them five stars, with no earlier history to weigh them against. That is a real but very short public track record, and it is the reason this rating sits below the star average rather than on top of it. Worth a call for slate, an old roof, or a roof-plus-gutters-and-trim job other roofers do not want. Before signing, ask for addresses from a few of those 2026 jobs, get the workmanship warranty in writing, and ask for current proof of insurance — routine checks that matter more when a company's public history is this new.
