Mold Science Environmental

Mold Science Environmental is a Bedford, New Hampshire mold inspection, testing and remediation company run by owner Mark Carter, who personally handles inspections and remediation work for homeowners in southern New Hampshire. The company's track record, drawn from 28 reviews across Google, Angi and HomeAdvisor between 2019 and 2023, is overwhelmingly positive. Homeowners consistently describe Mark as thorough, responsive and willing to explain what he finds and why. In a 2022 review, one customer said his approach reflected real training rather than "a simple online certification," and several others said he called back quickly, kept them updated by phone and email, and walked them through next steps. Several reviews describe concrete outcomes. In a 2020 review, a homeowner said a serious basement mold and water-damage problem was fully resolved within about a week of the initial visit, describing the house as going from "a toxic wasteland" back to safe. In a 2021 review, another customer said an attic mold job left the space looking newly rebuilt, with the guarantee holding since. One review stands apart from the rest. In a 2019 review, a customer disputed the accuracy of Mark's own testing, saying a second and third opinion from other firms found the sampling method flawed and that her insurer rejected the results; she also raised that the same company handling both the testing and the remediation work is a conflict of interest worth asking about. A separate 2022 review described waiting about a week for lab sample results without stating how that job ultimately concluded. Angi and HomeAdvisor both list this business at 4.8 stars from 40 reviews with the same review text, which is most likely one set of reviews mirrored across the two platforms rather than two independent bodies of feedback; Google shows a separate 5-star average from 5 ratings. Anyone considering this company for mold work should ask directly about the testing methodology and whether an independent second opinion is available before committing to a remediation quote. Most customers over the company's multi-year history describe a positive, well-explained experience, but the one detailed written complaint on file centers specifically on that question.
