Alf Curtis started out as a siding company, and that’s why we proudly offer Gentek vinyl siding, specialty tools and accessories, aluminum building products and more. Our partnership began in 1975 when Alf Curtis started selling Alcan, which later became Gentek. Gentek makes quality products that they stand behind, and we know customers will be happy when they get it on their house. 

Today, Alf Curtis remains a trusted siding source. As the region’s Gentek one-step distributor, we’re able to pass these savings on to you.

Gentek  is available at all locations. Don’t see what you’re looking for? We’re happy to order it for you.
