No hot water this morning? Hard water ruining your fixtures? We repair, replace, and install tank and tankless water heaters — plus whole-home filtration, softeners, and reverse osmosis systems.
Hot water delivery in Arlington and Alexandria's older homes was often an afterthought in the original design, with water heaters tucked into basement corners connected by long, uninsulated copper runs that waste energy and make you wait a full minute for hot water at the kitchen sink. We solve this with strategic recirculation loops, point-of-use tankless boosters, and insulation retrofits that dramatically improve both comfort and efficiency. On the filtration side, Alexandria's independent water system and Arlington's supply from Washington Aqueduct both benefit from point-of-use carbon filtration that removes residual chloramine taste, which is a particular concern in older buildings where internal plumbing may leach trace metals into standing water.
Arlington and Alexandria's housing stock was designed in an era when a single 30-gallon tank in the basement was considered adequate for a family. Today's expectations for instant hot water, multiple simultaneous showers, and filtered drinking water at every tap require thoughtful system design that works within the physical constraints of these older buildings.
Long, uninsulated hot water runs in pre-war Arlington and Alexandria homes waste significant energy and create wait times of sixty seconds or more at distant fixtures, frustrating homeowners who expect instant hot water.
Older buildings in Alexandria with lead solder joints or galvanized risers benefit from point-of-use filtration that captures trace metals leaching into water that sits in these aging pipes overnight.
Basement water heaters in historic homes often lack modern safety features like expansion tanks and seismic straps, and retrofitting these in tight, century-old mechanical rooms requires creative problem-solving.
