Seaside Exteriors provides a variety of specialty outdoor décor from Walpole Outdoors^™, ranging from pergolas, fencing and arbors to mail and lantern posts. For over 85 years Walpole has crafted these structures in Northern White Cedar. Today, Walpole offers many of these products in advanced AZEK^®. Preferred by many homeowners because it looks exactly like wood, AZEK won’t rot, split, or warp, and needs little-to-no maintenance for many years. Some of these options are designed to enhance your home, business, or landscape, while others are purely functional.
