Frequently asked questions
Often, yes. If your tank has failed we can usually get a like-for-like replacement in the same day you call (707) 308-5599. Tankless conversions take longer because of gas and venting work.
A tank is cheaper up front and simpler. Tankless costs more to install but lasts about twice as long, saves space, and never runs out of hot water. The right pick depends on your hot-water use and gas setup. See our tankless vs tank comparison.
Yes. California requires a permit for every water heater replacement. We pull it and schedule the inspection as part of the job.
