Building Supply Near Selden

Looking for a building supply near Selden that can cover more than one part of the job? At 9 Brothers Building Supply, we help contractors keep projects moving and give homeowners practical guidance for outdoor upgrades, repairs, and new construction. We carry masonry, hardscape, construction, and bulk materials for jobs throughout Long Island, NYC, and the Tri-state area.

Our East Setauket yard is convenient for many Selden-area customers, with additional pickup locations in Brentwood and Riverhead. Whether you need a few materials for a repair or a larger order for an active jobsite, our team can help you put together the right list.

Masonry, Hardscape, Construction, And Bulk Materials

We stock materials for patios, walkways, retaining walls, veneers, foundations, site work, drainage, outdoor kitchens, landscape projects, and everyday construction needs. Contractors rely on us for jobsite staples, while homeowners can get help sorting through products for projects around the house.

Our inventory includes pavers, wall systems, brick, natural and manufactured stone, concrete accessories, drainage products, venting solutions, sealants, tools, soils, aggregates, sand, gravel, and other bulk materials.

Here is a tip we give at the counter. Plan the full material assembly before ordering. A paver project often needs base material, bedding sand, edge restraint, jointing sand, and drainage products in addition to the pavers. Getting the full list together before delivery or pickup helps avoid extra trips.

Brands We Carry

We stock 4 Seasons, Laticrete, Sika, ADA Solutions, Inc., Smart Vent, MAX, Monarch, Stego, Husqvarna, W.R. Meadows, Alliance, Dutch Quality Stone, Eldorado Stone, StoneCraft, Kindred Outdoors & Surrounds, Espoma, Reed & Perrine, Delgado Stone, Cambridge, Glen-Gery, MSI, Nicolock, Techo-Bloc, Unilock, and Watsontown Brick.

These brands give our customers options for structural work, moisture protection, concrete and masonry installation, hardscape projects, stone veneer, outdoor living features, landscaping, and finishing details. Tell us what the project calls for, and we can help you narrow down the materials that fit the application.
