Customers frequently cite the company's punctuality, thorough testing, and clear communication regarding asbestos, lead, and air quality assessments. Reviewers note that the firm provides accurate cost estimates, timely report delivery, and helpful explanations of results. However, a recurring criticism involves missed appointments without prior notice or rescheduling attempts, which contrasts with the generally positive feedback regarding responsiveness and professional service.

We recently had recessed lights and a bathroom fan put into our home. Like many, we had the afterthought of the potential contaminants that may have been released during the project construction. I immediately Googled asbestos testing so we could be better aware of potential exposure.
I read all the reviews for Tri-Tech and called Joe right away. He was able to get out to my home the same day, collected diverse samples, and was helpful in answering all of my questions. I was in a bit of a panic and his demeanor was very calm, realistic, and informative.
Results were back quickly (luckily negative) and he was helpful in providing insight into the process. Pricing was extremely fair and their website is top notch for anyone trying to educate themselves.
Couldn't have asked for a better company to navigate a less than ideal situation. Thanks again, Joe!

We are a custom home builder and have happily been using Joe for multiple years now. He inspects our tear downs prior to demolition for hazardous materials. Very thorough and detail oriented. Meets all his schedule dates and quickly turns around the reports.
He's been an awesome resource for us and we're glad to have him part of our team.
