Environmental Testing and Consulting Services

RTK Environmental group

An environmental issue in your home or business — like mold, lead, asbestos, poor indoor air quality, contaminated water, and other hazards — can cause health issues, property damage (including loss of value), and disruption. For over 25 years, RTK Environmental Group has provided environmental testing services to more than 40,000 commercial and residential customers. RTK’s top priority is your health and safety. Our knowledgeable staff can answer your questions and concerns, and our customer service is second to none. 

We are a trusted leader in unbiased environmental testing and inspection for mold, lead, asbestos, indoor air quality and VOCs, water, soil, and radon. Serving southern New York (including the Five Boroughs, Westchester, Long Island, and the Lower Hudson Valley), Connecticut, and northern New Jersey, our professional inspectors are fully certified, licensed, and insured. Because RTK Environmental Group performs testing and does not remediate, we have no conflict of interest, often saving our clients thousands in unnecessary or over-inflated repairs.

No Conflict-Of-Interest. Ever!

RTK is an independent, certified testing company that never conducts remediation. 
We also use independent testing labs.
Therefore, RTK’s results are always unbiased and accurate.
