Herndon’s range of housing means a Herndon water heater call could be a decades-old tank in an established home or a builder-grade unit in a Kingstream townhome that’s aged out early. Hard water shortens any tank’s life here, so flushing and timely replacement matter. We diagnose the unit, give you the honest repair-versus-replace math, and size any replacement to your household.
