Exceptional Professionalism and Expertise
David and Sergio handled my plumbing issue with exceptional professionalism, expertise, and efficiency. When my tankless water heater failed, they responded quickly and had a new unit installed the very same day.
Sergio, in particular, took the time to thoroughly explain the problem, the replacement process, and the work being performed. His attention to detail and commitment to quality were truly impressive and gave me complete confidence in the repair.
I was amazed by how quickly they resolved the issue and restored our hot water. I am happy that I chose Nautilus Plumbing. Their high reviews are absolutely well deserved. Thank you, David and Sergio, for the excellent service and outstanding workmanship! Highly recommended.

They Always Do a Beautiful Job
Latest service was helping me get my apartment ready to show. They hooked up my stove, dishwasher, and washer-dryer. The previous job was replacing the water heater with a tankless one to give me more room in the kitchen for the washer-dryer. They always do a beautiful job, whatever they do for me. I love them 😍

The work was clean and professional
I woke up Sunday morning to no hot water. After failing to light the pilot light, I called around, but no one had immediate availability. I requested an appointment with Nautilus online, and it was confirmed shortly after. The guys arrived early the next day to check out the current system. They explained the issue with my gas heater very clearly (broken part), without pushing any additional work or upgrades. After they left, I called back to inquire about pulling the trigger on a tankless heater instead, and again, the team showed up within the hour to get that measured and quoted. We ended up going tankless, and the install was scheduled for the next day. The work was clean, the team was professional, and the tankless heater looks/works great. I'd recommend Nautilus to anyone - especially those with little knowledge or experience re: plumbing.

They Are Terrific!
We have used Nautilus Plumbing a few times and they are terrific! They answered my call on a Sunday and came the next morning for a sink pipe replacement. They have also done two other emergency sewer pipe repairs for us in the past. They are always very courteous, on time, and always clean up well. They are also very nice and patient with my questions. I would highly recommend them and won't use other plumbers again.

He was so, so, so kind
Luis came by to give us an estimate to install our commercial dishwasher, which was broken, and we had an appointment the very next day to get it looked at and fixed ($$$ 😬). In the process of inspecting for his estimate, he found the broken wire that I had been searching for for a week. He was so, so, so kind and so forthright on what and why things cost how much they would cost. He was very fair with his estimate too.

Answers to Top Questions
What is a tankless water heater?
A tankless water heater provides hot water on demand without storing it in a tank. It heats water directly as it flows through the unit, offering a continuous supply of hot water.
Does hard water affect my tankless heater?
Yes, hard water can cause mineral buildup, affecting efficiency and lifespan. Installing a water softener or scheduling regular descaling can help mitigate these effects.
How do I know if my tankless heater needs repair?
Signs your heater needs repair include fluctuating water temperatures, low hot water pressure, error codes, or unusual noises. If you notice these, it’s time to call a professional.
How long does tankless water heater repair take?
Repair time varies depending on the issue, but most common problems can be resolved in a few hours. More complex issues might require additional time or parts.
