Welcome to Cosco Fence & Guardrail

At Cosco, the fencing trade is part of our heritage. Our experience extends well beyond our 35 years as Southern New England's premier fencing specialists. In fact, our background in the industry spans three generations. If you traveled anywhere in Rhode Island and Massachusetts, chances are you've seen our work firsthand - or at least driven by it. At Cosco, we pride ourselves on installing fences and guardrail that are strong, secure, and possess the structural integrity to provide year after year of maintenance-free protection and containment performance.
