Hot water shouldn’t be a guessing game. In Littleton’s mixed housing—classic streets near Historic Downtown and Main Street, townhomes by Aspen Grove and the Mineral light-rail station, and neighborhoods stretching toward Columbine Valley and Roxborough—water heaters work hard year-round. Add our elevation and Denver hard water supply, and you’ve got real-world wear: scale buildup, noisy operation, temperature swings, and premature part failure. If you’re seeing rusty water, lukewarm showers, a leaking tank, or an error code on a tankless unit, it’s time for an altitude-savvy checkup.
Done’s licensed plumbers repair and replace all types of systems—standard tank, high-recovery, power-vent, and tankless water heaters. We arrive stocked for the issues we see most in Littleton: failed thermostats and heating elements, worn anode rods, clogged flame arrestors, pressure/temperature relief problems, and condensate or venting faults on high-efficiency units. Because many Littleton homes have pressure-reducing valves, we also verify that your thermal expansion tank is present, properly sized, and set to match house pressure – key to protecting fixtures and the new heater. For tankless systems, we descale the heat exchanger, confirm gas supply and combustion at altitude, and dial in recirculation for faster hot water to far bathrooms.
Planning an upgrade? We’ll right-size a replacement that fits your space and usage, handle permit/inspection, rework venting to current code, and haul away the old unit. Prefer lower operating costs? We’ll compare high-efficiency tank and tankless options, including recirculation controls and mixing valves, for comfort, safety, and savings.
