Mold Dog of Massachusetts

Mold Dog of Massachusetts is Gretchen and her trained mold-detection dog Frances, working out of Buzzards Bay to find hidden mold that other inspectors miss — dozens of reviewers describe hiring them specifically because a prior inspection, or unexplained health symptoms, hadn't turned up an answer. The pair's process combines Frances's nose with lab-tested air and surface samples to pinpoint exactly where mold is and confirm it. The track record runs to 31 reviews from 2024 into 2026, nearly all five stars, and it tells a consistent story: Frances alerts to a location, Gretchen decides where to sample, and lab results confirm or rule out a problem. Several reviewers say this avoided tearing up an entire house to chase mold blindly. In a May 2026 review, a buyer said Gretchen caught mold problems before a home inspection that would have cost thousands to remediate if missed. Multiple reviewers describe searching for answers to unexplained asthma, allergy or immune symptoms and finally getting a concrete answer. In a January 2025 review describing a November 2024 visit, a customer said Gretchen traveled out to Western Massachusetts at their request — beyond the Boston and Plymouth area the company lists as its service area. The one discordant note is an April 2025 one-star review urging prospective clients to verify the company's NORMI certification and business registration directly with NORMI and the state, get a written contract, and confirm they'll receive a professional written report. It reads as a caution about documentation rather than a description of bad work, but it stands apart from an otherwise unusually consistent run of detailed, enthusiastic reviews. The website lists NORMI certifications as a Mold Assessor, Mold Remediator and Advanced IAQ Assessor, plus an IICRC Building Moisture Inspector credential — third-party industry certifications rather than a state license, and self-reported rather than independently verified here. For pinpointing hidden mold — especially when a standard inspection has come up empty or symptoms don't have an obvious cause — Mold Dog has an unusually deep run of specific, credible praise. Given the one review flagging documentation, it's worth asking upfront for a written scope of work, the certification numbers, and a guaranteed written report before booking.
