1040 Division St. Stevenson Building Products has been a family owned and operated business since 1979. Originally going under the name Creative Glass Studios, the primary focus of the business was as a stained and leaded glass retailer specializing in ecclesiastical window restorations to churches in the Northumberland County. Throughout the years the business has expanded to include various types of residential and commercial exterior products and applications which prompted the name change to Stevenson Building Products in 2004. Stevenson Building Products primary business focus is now geared towards residential windows for both new construction and replacement applications. SBP also carries a complete line of exterior siding products, patio doors, entrance systems as well as aluminum flatstock, soffit and eaves trims, shutters, caulking and other related products. With our diverse network of builder related products we can fulfill most exterior finishing needs selling at both a wholesale and retail level. SBP is also the dealer for Guildcrest modular homes with many different design and layout options. We, the SBP family, pride ourselves on quality products, excellent service and of course the best price around. Unique to our situation, our business is located on First Nation Territory which allows us the distinct opportunity to offer our product tax free.
