Exceptional Service & Unwavering Support We can’t say enough good things about Stewart Environmental. In 2024, we faced a stressful situation with a heating oil spill, and their team was there for us every step of the way. From the very beginning, they treated us like family—guiding us through the entire process with professionalism, expertise, and genuine care. Even after the job was complete, they remained incredibly responsive, always happy to answer any follow-up questions—even during the sale of our home. Their dedication and willingness to go above and beyond truly set them apart. If you ever find yourself in need of environmental services, we highly recommend Stewart Environmental.

The crew was forthright in their plans for each day, provided details of excavation plans throughout the project, and was easy to work with for the collection of over 30 samples. They were efficient in their efforts and didn't waste time. They provided detailed explanation to the client of the remedial work. I would highly recommend Chris and his team for any project.

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.

“Our company has had Stewart Environmental Remediation do multiple projects from the simplest project to all types of construction and complicated renovations. At all times the owner and staff are professional, pleasant and thorough. The management and staff are sensitive to causing any business interruption while they are on our property and projects are completed on time and within budget. We have used Stewart Contractors for several years and will continue to use them for their quality of work and professionalism.”
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 This Hackettstown Hospital job comprised removing and disposing of an outdated 10,000-gallon UST and re-installing a state-of-the-art 10,000-gallon dual fuel Underground Storage Tank that they use in the event of an outage.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.”
