Licensed in NJ, CT, DE and PA

I have used Chris and Deb many times over the past five years on environmental remediation projects in NJ and CT. Chris has a great understanding of the complexities of environmental projects and has years of experience to draw on when an unforeseen condition presents itself. I always feel comfortable when Stewart is on the job and I know the job will get done correctly!
Ryan Reynics
As an environmental professional in the consulting industry for over 16 years, I have worked with Stewart Builders / Stewart Environmental Remediation Services for the entirety of my career and I can attest that they are a professional, reliable, and competent subcontractor. Stewart specializes in tank removals and is very adept at this type of work; I myself have worked with Stewart to oversee and remediate dozens of UST jobs throughout the course of my career. They are also capable of handling larger soil remediation projects, of which type I have worked with them on several. Throughout my experience with Stewart, I have always found them to perform the work thoroughly, safely, and with a quality that’s meeting or above expectations.
Aaron Epstein
As an environmental consultant, solid contractors are so important to overall job success. Whether it be tank removal services, hotspot soil removal, test pitting, or waste hauling, Stewart Environmental Remediation is my number one choice by a longshot. Chris, Deb, and their staff make an excellent team and are always a pleasure to work with. Unlike some other contractors that require constant hand holding/follow up and hit you with change orders in the middle of the project, Stewart is always so well prepared for every job and are excellent communicators. They are experts at their craft. No matter how difficult of a job, they will always find a way to a successful end result while staying within budget every time. I look forward to working with them for many years to come. Highly recommended. Thank you Chris and Deb for all of your hard work on my projects!

I have worked with Stewart Environmental Remediation, specifically with Christian, for well over 10 years. He has closed underground storage tanks for me from Pennsylvania to Maine. I have used Stewart for several projects ranging from difficult above ground tank removal and replacement, difficult UST abandonment/closures, soil remediations, waste removal, etc. Christian and his team are professional, quick, affordable, responsive - but most importantly experienced. He is always my first and preferred choice and recommendation for anybody needing these types of services. It is a pleasure to work with Stewart Environmental Remediation.
