About RTK Environmental
A Trusted Leader in Environmental Testing
RTK Environmental is a trusted leader in unbiased environmental testing and inspection for homes, businesses, and institutions across New York, Connecticut, and New Jersey. For more than 30 years, RTK has provided professional environmental testing and consulting services to over 45,000 commercial and residential customers. Our top priority is protecting your health, safety, and property by identifying environmental hazards and delivering clear, actionable guidance.
Environmental issues in a building—such as mold, lead, asbestos, poor indoor air quality, contaminated water, radon, soil pollutants, soot, or other toxins—can cause serious health problems, reduce property value, and disrupt daily life. RTK’s role is to diagnose these issues accurately, explain what they mean, and outline the practical steps you can take to fix them.
What RTK Environmental Does
RTK focuses exclusively on environmental testing and consulting, not remediation, so our results remain completely independent and free of conflicts of interest.
Key testing and inspection services include:
- Mold inspections and mold testing
- Lead paint inspections and lead dust sampling
- Asbestos inspections and asbestos testing
- Indoor air quality testing and VOC testing
- Water quality testing (drinking water and building systems)
- Soil testing and contamination screening
- Radon testing
- Soot, smoke, and fire/soot damage assessments
- Abatement and remediation planning, management, and environmental consulting
By performing only testing—not cleanup—RTK often helps clients avoid unnecessary or inflated remediation costs and ensures that recommendations are based solely on accurate data.
