Chimneys in Rockland and Westchester Counties face extreme seasonal stress. Winter snow builds up around flues and flashing. Spring rain finds every crack in aging mortar. Summer heat expands joints and pulls apart caps. Don’t take care of a chimney and it’ll leak, clog, maybe even catch fire. We’ve been at this in the area for 20+ years, fixing, cleaning, rebuilding. Work’s done safely so the air moves right. Wood or gas, what it needs depends on the chimney, the weather, and the fuel.
