Saint John’s coastal climate brings salt air, heavy winds, and long, wet winters that can wear down roofs, concrete, and wood. At NanoSealNB, we proudly serve homeowners across the Saint John region—including East Saint John, West Side, Millidgeville, and Rothesay—with proven GoNano treatments that extend the life of roofs by up to 15 years. Our team is local, and we’re committed to helping Saint John families protect their homes and avoid costly early replacements.
