Nauset Environmental Services says it takes no referral fees or commissions from remediation work and has no affiliation with remediation contractors. Its work is indoor-air-quality testing and inspection: mold and moisture investigations, radon testing and pre-demolition asbestos inspections on Cape Cod. The company is based in Eastham. The company says William M. Vaughan founded it in 1998 and Thomas Knight acquired it in 2023. Knight is now its owner and president; Vaughan remains founder and principal scientist emeritus. Its website identifies Knight as a Certified Industrial Hygienist and lists asbestos-inspection and mold-inspection credentials among the firm's qualifications. In a December 2022 Google review, a homeowner described seeking help with moisture problems after a referral from Whalen Restoration. The customer said Dr. Vaughn returned the call the next day, arranged an appointment for the following day and explained the cause of the moisture and how to address it. The customer praised the pricing and reports and said the explanations helped them manage without hiring a large outside cleanup company. A customer writing in August 2021 described asbestos testing of a popcorn ceiling, followed by further testing after inconclusive results. That customer also praised Dr. Vaughan's willingness to answer additional questions. In an April 2013 HomeAdvisor review, a Realtor described Vaughan shipping a suspected-asbestos sample overnight to a laboratory and requesting a six-hour turnaround; the Realtor said results arrived the next afternoon and showed no asbestos. A February 2024 Google reviewer praised arrival as scheduled, ease of working with the company and quick laboratory results. Google lists five stars from 26 ratings, and BBB assigns an A+ grade. The Vineyard Gazette has reported criticism of Nauset's reporting. The BBB profile still identifies William Vaughan as president and gives an East Orleans PO box and phone number. The company's website describes the 2023 ownership change to Knight and uses its Eastham address and a different phone number.
“the treatment was recommended by Nauset Environmental Services, which determined after an inspection that the floor was susceptible to water infiltration.”
“after Massamont deemed insufficient a nine-page report prepared by Dr. Bill Vaughan of Nauset Environmental Services of East Orleans.”
“Representatives from Nauset Environmental Services flew in yesterday morning to check levels and will prepare a checklist for the town administrator.”
“William Vaughan, of Nauset Environmental Services, which covers indoor environmental issues from Plymouth to Provincetown, said radon also can creep into homes through the pores of concrete.”
Great job. They came when they said they would, and they were easy to work with. Lab test came in quickly, too. Nauset Environmental is a great outfit!
What can I say. I mean where do I start? Professional! Reliable! Honest! Informative! Patient! The list goes on. I was referred to NES inc. from Whalen restoration co. for a test on my home environment for moisture and such. Dr.Vaughn returned a call to me the very next day .He was direct in his plan and set up a appointment for me the next day I was so appreciative to him for his prompt and serious attention. He helped me so much figure out why my home was creating too much moisture and how to remedy it. The pricing is more than fair and the quality of the reports are fantastic. I was able to manage without having to hire a big outside cleanup company. Dr.Vaughn explained everything I needed to know in order to help myself, I’m so thankful for his experience and his willingness to help. I will most definitely recommend this company to everyone I know. Thank you again. Samantha
Dr. Vaughn is an experienced and highly knowledgeable indoor air quality expert. He brings a practical and educational approach to his consultation while providing specific guidelines for improvements that can be made to prevent issues with mold or allergens. He is an excellent and trusted resource.
Oh, what a relief! A home inspector scared me, but Dr. Vaughn came right away and did an inspection. Not only tell me I did not need a mold remediation, he taught
Dr. Vaughan helped me test whether my popcorn ceiling contained asbestos and then further tested it after the results were inconclusive. He is a consummate professional who has also been willing to answer additional questions. I highly recommend NES for any of your asbestos testing needs.
