La Jolla's diverse housing stock — from the Spanish Revival estates of the 1920s to the celebrated mid-century modern homes by architects like Richard Neutra and Craig Ellwood to the luxury contemporary builds along the coast — contains plumbing systems spanning nearly a century of building practices. Many of these homes still operate on their original galvanized steel or early copper supply lines, materials that have been deteriorating from the inside for decades. Galvanized pipes develop layers of rust and mineral scale that progressively restrict water flow, eventually reducing pressure to a trickle. Early copper with lead-based solder (used until 1986) can leach metals into drinking water. Both materials are well past their designed service life.Homewerx specializes in whole-home repiping with modern PEX (cross-linked polyethylene) or copper, selecting the optimal material for each home based on layout, water chemistry, and homeowner preferences. Our minimally invasive approach routes new pipes through existing wall cavities, chases, and access paths to minimize drywall cuts and preserve original finishes. For La Jolla's architecturally significant homes, this means protecting plaster walls, period woodwork, custom tile, and other irreplaceable details. A complete repipe typically takes 2–5 days and delivers immediate results: dramatically improved water pressure, clean water free of rust and sediment, elimination of leak risk, and significantly increased property value.
