Highly Recommend Stewart Environmental Remediation. We had two abandoned oil tanks removed. From the first phone call for an estimate to the completion of the job everything was done in a friendly, efficient, timely and professional manner. I was impressed with how the crew managed to get the 1000 gallon tank out of a tight spot. The whole process was effortless (on our part). Thank you!Posted on Google Michael LowryTrustindex verifies that the original source of the review is Google.

I appreciated the fair price and the care given to this project.Posted on Google ALAN IANUZZITrustindex verifies that the original source of the review is Google. I placed my faith in Stewart Environmental Remediation and recommended them to two family members. One Underground Storage Tank removal was located in a crawl space and the other in a narrow side yard. Their estimates beat the competition handily! Both jobs were completed on time with no additional charges. Put your trust in Stewart, you won't be disappointed!Posted on Google Jacqueline GonzalezTrustindex verifies that the original source of the review is Google. The company was a joy to work with even through a troubling situation. Middle of a sale when an old tank was found. Was easy to contact them, quick on filling and submitting the permit properly to have the tank removed, quick to putting us on their schedule once the permit was processed(even adding us quickly because of time constraints), and getting the job done in one day(tank turned out to twice the size we expected)!Posted on Google Bettyann LemongelloTrustindex verifies that the original source of the review is Google. Stewart Environmental was a pleasure to work with. Debbie runs a very professional business with accuracy and promptness. Whenever I called with a questions, Debbie would answer the phone and I was never put on hold. Employees Lou and Carlos were very pleasant and efficient in their work and got the job done proficiently.Posted on Google Brian KleinTrustindex verifies that the original source of the review is Google. Stewart Builders did an excellent job installing a new drain and driveway at our property. The crew was professional, the work was clean, and the finished result looks great. They showed up when they said they would, kept the site organized, and left everything tidy at the end. Highly recommend if you need this kind of work done.Posted on Google HHB Valentine, LLCTrustindex verifies that the original source of the review is Google. We recently worked with Stewart Environmental to have an oil tank removed in Hackettstown and they made the entire process easy. They were professional, responsive and easy to work with. They answered all of our questions through all the steps of the process.Posted on Google Steven GabelTrustindex verifies that the original source of the review is Google. There are truly not enough stars for the team at Stewart Environmental. I feel very lucky to have found them. From the start, their responsiveness and follow-up stood out, when they said they would be somewhere or complete something, it actually got done. When we ran into unexpected issues, they were proactive, clear in their communication, and thoughtful about solutions, walking us through options rather than pushing a one-size-fits-all answer. Most importantly, they executed the work flawlessly and got our oil-water separator (OWS) system up and running on schedule. If you’re a small business or property owner looking for a reliable, professional environmental firm that does what they say and stands behind their work, I can’t recommend Stewart Environmental highly enough.Posted on Google Claudia WestTrustindex verifies that the original source of the review is Google.

Global Auto Mall

North Plainfied, NJ
We have completed several large and many small projects over the last several years at Global Auto Mall. We started working on an environmental clean-up project that led to many other projects throughout the dealership. In 2021 we removed 28 underground hydraulic lifts from the service center garage. The general manager knows when she needs anything done, all she needs to do is call.

Partner Engineering and Science

Hackettstown Hospital, NJ
This is one of many underground storage tank removal jobs for Partner Engineering and Science. This Hackettstown Hospital job comprised removing and disposing of an outdated 10,000-gallon UST and re-installing a state-of-the-art 10,000-gallon dual fuel Underground Storage Tank that they use in the event of an outage. They are proactive in removing and replacing their tanks before the end of the tank life expectancy.

“Stewart Environmental has been a contractor for Partner, mainly for UST and AST investigations and closures, as well as waste disposal, in the mid-Atlantic for many years. Their professionalism and communication make them my first choice in these services throughout a significant portion of my territory, to areas far beyond what others would expect.”
Fairmount Cemetary

Newark, NJ
Our longstanding relationship with Fairmount Cemetery started with a fairly extensive contaminated soil remediation. Throughout the years, they have had us do many large and small projects, from cleaning out and rebuilding catch basins to demolitions an old maintenance building at the Newark property and building a new maintenance building at their sister property Somerset Hills Memorial Park in Basking Ridge.

“As the President of Fairmount Cemetery Association of Newark and Somerset Hills (NJ), I recommend Stewart Builders without hesitation. For the last several years, Stewart has served us ably on five major projects and a number of smaller projects, including the construction of a new service building, the demolition of three large century-old brick buildings, and two soil remediation excavations required by NJDEP. Stewart has been consistently attentive to project design, scheduling, and estimating, to securing all required governmental approvals, to enlisting subcontractors when necessary and seeing to the progress and completion of the work on target as to schedule and cost. Chris and Debra are knowledgeable as to their business and thoroughly professional in demeanor.

“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.”
