With stores in Massachusetts, New Hampshire, Maine and Rhode Island, Swenson expanded to include its Newtown facility in 2000. Customers may visit the yard on Route 25 to see examples of granite steps, posts, pavers, curbing and ornamental stone products. Installation is available for some products. It supports the community by supplying granite products to the local government and various community organizations.
