Long Island's highest quality hardscaping and building materials.
Conveniently located on the Nassau-Suffolk border in Huntington Station, NY, County Line Mason Supplies has been providing customers with dependable service and the widest selection of quality hardscaping and building materials since 1987.
We've carefully built our reputation by making your project our top priority.
As one of Long Island's largest mason supply yards, we understand that where you buy your material can be just as important as what you buy. With so many product brands, styles and colors available, selecting the right material for your project can be daunting. Our friendly and knowledgeable staff can help you to choose the right material, locate hard to find products and identify options to complement and enhance your project's design. We also have over 6,000 square feet of products on display so even when our yard is closed you can visit at any time to get hardscaping ideas.
Whether it's topsoil in the spring, cement in the summer or calcium chloride in the winter, we believe that the only time you should lift a heavy bag of material is when you need to use it, not when you buy it from us. That's why you will never find a shopping cart at County Line...any product you purchase from us will be loaded into your vehicle or delivered to your home or job site.
Quality materials, wide selection, dependable service and customer satisfaction is what County Line Mason Supplies is all about.
