Nauset Environmental Services

Nauset Environmental Services is an independent indoor-air-quality testing and inspection firm based at 115 Squanto Rd in Eastham, serving Cape Cod, Martha's Vineyard, and Nantucket. The company states it was founded in 1998 by William M. Vaughan, PhD, and has been run since 2023 by Thomas Knight, a Certified Industrial Hygienist, after Vaughan stepped back to an advisory role. NES specializes in mold and moisture investigations, radon testing, and pre-demolition asbestos inspections, and states plainly that it is not affiliated with any remediation contractor and takes no referral fees when it points customers toward remediation work. The written review record is small but consistently positive, spanning 2011 through 2024. In a 2024 review, a client praised the company for showing up on time and returning lab results quickly. In a 2022 review, a homeowner said they were referred to NES by a restoration company for a moisture test and found Dr. Vaughan responsive, fairly priced, and thorough in his reporting. Older reviews from 2011, 2013, and 2021 similarly describe Dr. Vaughan personally handling asbestos and mold/moisture jobs, including a 2013 account of a same-day sample rush ahead of a real-estate closing, and a 2021 account of a homeowner avoiding an unnecessary mold-remediation contract after his inspection ruled it out. Google separately shows a 5-star aggregate from 26 ratings, and BBB lists the company A+ though not BBB-accredited. Because the written record is thin — seven reviews on file, most of them years old — it's worth asking directly about current turnaround times and pricing before booking, since the most detailed accounts describe Dr. Vaughan's own personal service rather than the current owner's. The company's certifications (Certified Industrial Hygienist, EPA AHERA asbestos accreditation, Council-Certified Residential Mold Inspector, Massachusetts Asbestos Inspector) are self-reported on its own site and directory listings rather than verified against a state registry, so it's reasonable to ask to see current credentials directly. NES is a good fit for a homeowner who wants a second opinion independent of any remediation contractor — someone deciding whether a mold, asbestos, or radon problem is real before paying anyone to fix it. Confirm current pricing, turnaround, and who on staff will actually perform the inspection.
