As Seattle water heater service providers, reviews are the gas that drives our engine. The most important thing for a service provider is its reputation, and the word-of-mouth praise we’ve received from thousands of satisfied customers speaks to our attention to detail.

“Our water heater started leaking Saturday morning. Finally found a company that would come out. Brandon C called 30 minutes before showing up. He showed up around 9am Easter Sunday morning. We had hot water by noon. Brandon went over the work that was needed and once I agreed he went to work. He did a professional job and when complete everything was properly connected. We didn’t have a pressure tank installed so had to add that. He also fixed the plumbing problems that were introduced when I installed the last water heater. When he was all done he even helped me put the cabinets back in the pantry where the water heaters installed. Great job.”

“I was really impressed with the quick turnaround and quality workmanship for this job. The technician (Matt S) was an awesome guy and did a really thorough job, even walking me through the details of the installation, and post “in case of a future emergency” list of things to address. Overall, a really solid company to work with.

I came home from Vegas to a flooded basement, and the next MORNING, I was taking a hot shower.

I’d totally recommend Fast Water Heater, and of course, Matt too!”
