Sewall's Point is strictly residential, with estate homes on large, tree-lined lots and water on almost every side. That kind of exposure means salt air and moisture reach every part of a home's exterior equipment, not just the side facing the river. We come prepared for it, with a 2-hour arrival window, a clear diagnosis, and a price before we touch anything. A $200 part gets called out as a $200 part, no surprises later.
