Water Heaters · Annandale, VA
Quick answer
LeMaster Plumber repairs and replaces tank and tankless water heaters across Annandale, including Broyhill Crest, Camelot, Hillbrook, and Sleepy Hollow. Annandale’s mid-century homes often have the heater tucked into a tight basement or closet, and we install cleanly in those spaces. Call (703) 832-9090 for upfront-priced water heater service in Annandale.
In Annandale’s 1950s and ’60s homes, the water heater is frequently wedged into a small basement, closet, or utility nook, and venting on older houses needs a careful eye to keep the install safe and to code. Hard water leaves sediment that shortens any tank’s life here, so aging units are common. Many owners use a replacement as the chance to upgrade capacity or go tankless — we handle the tight access and lay out repair-versus-replace clearly.
