Our foundation

Founded 1947 by the Quaranta brothers

A family business, trusted in Northern New Jersey for over 75 years.

Founded in 1947 by brothers Albert and Ralph Quaranta, Jefferson Lumber has built its reputation on quality products and craftsmanship, as well as superior service and knowledgeable advice. As a family owned and operated business, we develop a close rapport with our customers, and we promptly deliver to Morris, Sussex, Warren, Passaic and Bergen counties.

In our ten acre yard, we stock a full line of framing and treated lumber. The Douglas Fir we stock is graded standard and better, and our pressure treated lumber is Wolmanized .40 CCA from the best mills in North America. We carry a large inventory of plywood, from basic CDX fir ply-score to a large assortment of hardwoods and special furniture grade veneered plywood.

Our hardwood variety includes Red and White Oak, Philippine and Genuine Mahogany, Cherry, Maple, Birch, Poplar, Ash, Walnut, Hickory, Cypress, Spanish Cedar, Western Red Cedar, Ipe and Traditional Pine in clear and common grades. For exterior use, we carry a full line of primed pine and vinyl fascia boards.

Since 1947

Nearly 80 years in business.

Three generations of the same family, the same yard, the same promise. These photographs come from our own albums: the shop floor, the delivery truck, the stairs and railings built by hand, and the people who built them.
