Serving Concord Homeowners When It Matters Most

Concord grew fast in the postwar boom, and the city still reflects it: thousands of 1950s-70s tract homes in Sun Terrace, Sycamore, Holbrook Heights, Galindo, and North Concord. Newer subdivisions in Crystyl Ranch, Concord Hills, Dana Estates, and the Concord Foothills layer on top, with modest ranches near Downtown rounding out the mix.

Water Heater Boys provides same-day repair and installation across every corner of Concord. Our techs know the original tract-home closets — often tight, often vented through 50-year-old flues — and the bigger garages of Crystyl Ranch. Concord runs on Contra Costa Water District water, moderately hard, so sediment is built into how we service.

Common Water Heater Problems in Concord Homes

Concord’s older housing stock means we see plenty of long-overdue replacements:

• No hot water — failed thermocouple, tripped breaker, or extinguished pilot
• Original tract-home tank failures — many 1960s-70s Concord homes are on long-overdue tanks
• Rumbling and popping — sediment from CCWD’s moderately hard water
• Tank leaks at the bottom seam — terminal, requires replacement
• Rusty hot water — anode rod gone, tank corroding from inside
• Rotten egg smell — sulfur bacteria reacting with a depleted anode
• Pilot won’t stay lit — bad thermocouple or combustion air issue
• Old galvanized closet venting concerns — older Concord homes often need flue inspection during replacement
• Pressure relief valve dripping — excess pressure or overheating
• Slow recovery — undersized for current household demand
• Rising gas bills — efficiency loss from an aging tank

Brands We Install & Service in Concord

Bradford White — made in the USA and our top pick for gas tank replacements. Reliable for the high-volume swaps common in Concord’s older neighborhoods.

Navien — our preferred tankless brand. Condensing efficiency and good parts availability for remodels and Crystyl Ranch upgrades.

Rheem — widely available for tank and tankless. The ProTerra heat pump line qualifies for California rebates and fits Concord garages.

A.O. Smith — dependable tank and heat pump options with good local parts coverage.

We recommend the right brand for your home, not the highest-margin unit on our truck.

What Concord Customers Are Saying

“I made a request through Angi and this company was the first of three to respond. Dustin asked a few questions to make sure the replacement would match and work properly. The price he quoted was a little better than the others and included some extra stuff like the hoses and a drain pan. He was able to schedule an installation for the same day.

The installer, Raul, was very good, and did a neat, professional job. Total time was between 1.5 and 2 hours. I am happy with the results.“
