Get matched with top tankless water heater repair pros in Lacey, WA

"They came within a day and converted by old 3 knob setup to a more modern 1 knob setup which required cutting and reconfiguring pipes. The whole job was done in a half day and the shower/bath was repaired. Very nice plumber and front office team as well."

"Stephen Fry did a great job. He is dedicated and he did a wonderful job. Will ask for him if I need help again."

"Our water heater started leaking and the original installer advised we would need a “custom order” and a replacement part that wasn’t readily available. After research, we reached out to Washington Water Heaters for a second opinion. Steve was very knowledgeable and was able to scheduled us with a same-day appointment. Len identified the core issue, fixed the leak, and cleaned up all in 30 minutes. Stellar service , efficient, and very fair pricing. "

"I had them come out to do a 'tune up' and annual inspection. They found out why my bill was so high. The company who installed my all electric heat pump system (2023) programmed the thermostat (the contractor part, not the setting the user has access to) incorrectly. Hart changed it to what it should be. By my estimation I have likely overpaid on excess of $3,000 since I moved in to this new construction home. I highly recommended having them out to verify if your system needs help. If your electric bill is over $200 a month you should call them immediately. I wish I had called them in 2023. Can't recommend them enough. Also, Dan was on time, professional, tidy, and communicated well. "

"Great people, great service. Easy to connect and schedule with, prompt and friendly when they get here. Knowledgeable and fast with repairs and they go above and beyond to check other systems and potential problems to make sure we're totally covered. Could not recommend this company more!"

"He was able to come that day and completed the project to satisfaction. Was willing to make a deal for price since it didn't take too long to fix issue. Would hire again."

"efficient and professional."

"Bob Larson is a scam. I bought a $10,000 on-demand water heater in November 2023. Bob Larson Plumbing recommended and installed the unit; at first, it was great. Since December 2024, the system has been having issues randomly turning itself off. It was more of a nuisance than a real issue at first. I could turn it back on. Bob Larson was called and came out twice but could not resolve the issue. In March of 2025, the problem got worse, and hot water was random at best, even if I reset the heater manually. Instead of resolving the issue or exchanging it, Bob Larson Plumbing is trying to sell me another unit. I am still under warranty. My original receipt shows a 5-year warranty on parts and labor. Bob Larson is an upselling scam. They will not be getting any more of my money."

"Excellent work for a reasonable price!"

"Very helpful and efficient."
