Why Green Leaf Cares About PLUMBING LICENSURE, and why you should too:
Hiring a licensed plumber in New Jersey is not just a matter of preference—it’s a safeguard for homeowners and businesses alike. Licensed contractors in the state are required to meet strict standards set by the New Jersey State Board of Examiners of Master Plumbers, including passing rigorous exams, completing years of training, and maintaining proper insurance and bonding. When you hire an unlicensed contractor, you risk substandard work that could lead to costly repairs, safety hazards like leaks or gas line issues, and even legal complications if the work violates local building codes.
As a proud advocate for accountability in the plumbing industry, I believe New Jersey consumers deserve to know the risks of cutting corners with unlicensed workers who may lack the skills, credentials, or liability coverage to protect your property.
Reporting unlicensed contractors is a critical step toward protecting our communities and upholding the integrity of skilled trades in New Jersey. If you suspect someone is operating without a license, you can file a complaint with the New Jersey Division of Consumer Affairs, which investigates such cases to ensure compliance with state regulations. Unlicensed plumbers often prey on unsuspecting customers by offering lower prices, only to deliver poor-quality work that leaves homeowners footing the bill for fixes—or worse, dealing with property damage. By educating yourself and others about the importance of hiring licensed professionals, you’re not just safeguarding your own investment—you’re helping to maintain a higher standard for plumbing services across the state.

“My Husband Chris and I had an excellent experience with John & Joe. They dedicated time after hours to discuss the issue we were experiencing with our heating system and promptly arrived to resolve it at our home in Towaco. They provided thorough explanations and demonstrated a high level of professionalism throughout the process. Additionally, their pricing was very reasonable. We will certainly be reaching out to them again for necessary system servicing and any future needs.”

“Joe and John were a pleasure to work with. John picked up on a Saturday when I needed someone for my tankless water heater. He spent hours and was patient. As soon as the part became available on a Monday morning John and Joe came and fixed the issue. Their prices are very reasonable and where other plumbers told me to replace my unit these two gentlemen were honest and told me my unit was fine. It was easy to reach them and they are genuinely good plumbers.”

“Being referred to this company was literally a blessing. With a few issues happening in our building at the same time, everybody was really stressed and overwhelmed. The moment they stepped in, we knew we were in good hands. Absolutely professional, knowledgeable and fairly priced. To summarize- several water heaters were replaced in our building at the same time, by 3 different contractors. ONLY those installed by Green Leaf were installed according to the building code and had all necessary paperwork and permits. These guys are true professionals and a pleasure to work with.”
