Portland Stone Ware is a family owned and operated business dating back to 1847 serving the masonry and lumber industries. We started off as one of the largest manufacturers of Vitrified Salt-Glazed sewer pipe and firebrick on the east coast. Once pipe requirements were diminishing, PSW began to solely fabricate Portland Concrete Filled Columns but we have since expanded our product lines to thin veneer, stone and masonry products. We marry modern technology with old fashion values to provide superior service and top quality innovative building products for our customers as they are the bedrock of our business. PSW is a part of the following associations: - NRLA - NH Trucking Association PSW holds the following certifications: - Fork Lift Certification - ICC Regulated
