Featured Services

Our commitment to our customers is summed up by our President, Sheldon Kahan, "Customers who work with us come to know that we regard our relationships as partnerships. It's simple logic, if our customers are successful, so are we. The quality of our product mix, the extent of our services and our competitive pricing, reflects this attitude and commitment. We're not looking to be the biggest, but rather the best. We want to create a good, strong following among contractors, developers and homeowners. The way we do it is to prove that they can depend on us."
