Full-Service Construction Contractor

At MJG Contracting Corp., we don’t just build—we take ownership of the construction process from the ground up. Whether you're renovating, expanding, or starting from scratch, we manage every detail with the precision, grit, and integrity that defines our reputation across Long Island and the Tri-State area.

🧱 Construction Management Built on Accountability

Construction projects are complex by nature—especially when they involve occupied spaces, tight urban logistics, or aggressive timelines. At MJG Contracting, we eliminate the chaos by taking a hands-on, solutions-oriented approach. From demolition to final walkthrough, we ensure your project is built right and built on time.

Our construction managers collaborate with architects, engineers, designers, and trades to continually monitor scope, cost, and schedule. We proactively identify issues before they arise, ensuring a smooth build and an exceptional finished product.

👷‍♂️ On-Site Leadership You Can Trust

While our team is stacked with seasoned professionals, every project still benefits from the direct involvement of our President & CEO, Michael. His on-site presence and industry knowledge offer clients peace of mind throughout the process. With over 30 years in the construction industry, Michael understands what’s at stake—and he ensures that no detail is overlooked.
