"This is a high quality mold/fungi/fungus testing company, with excellent customer service and follow-up. The phones were picked up on the first call each time, and arranging for an appointment was very easy. They arrived on time, were efficient, informing, and friendly in their work, and brought commercial equipment to perform the test samples. The follow up phone call and email on the test results was good, and they provided a potential remediation plan for us to follow on the test results. The third party lab utilized by them had easy to understand numbers, graphs, and descriptions of what was tested. We will do business with Gardner Services again in the near future, and will recommend them to others."

"We hired PureTech to advise us on a real estate inspection that included a radon test. That test came back over the safety threshold. After meeting with Zach C, he advised us to make some repairs in the basement and to schedule a retest. We did and the results speak for themselves; the levels came back well into the safe zone. I couldn't be more pleased with the recommendations made by PureTech and Zach C specifically. Saved us a bundle in what could have been a nightmare, and now the sale of our home can proceed. Thank you PureTech!"
