Outstanding service. Nick and team cam out to walk us through our house and quickly resolved a few issues we were having with our water heater. Very knowledgeable and responsive. Will be using for all our plumbing needs.

Nick, John and team did a fantastic job installing an awesome Nevian tankless water heater. Unit works great. Excellent work and service!
First String Plumbing, Heating & Cooling's reply
Hi Doug - Thank you for trusting us to upgrade your traditional water heater to a tankless water heater. When you called at 7:45 pm with a busted water heater and 1" of water flooding your basement mechanical room I had to move quick. We take pride in our work and serving community. Looking forward to servicing your steam boiler and new tankless water heater next spring!

Im so glad I found First String Plumbing and Nick. They are extremely professional and upfront about what needs to be done. They replaced our water main, upgraded all of our old valves to ball valves, and installed new hose spigots in our older home.Nick and his team were professional, clean, reliable, and fastthe job was completed the day after they came to look at what needs to be done. What he says is exactly what it is, with no surprises.Theyve earned our trust and will be our first call for any plumbing needs moving forward.

I love these guys, they were there when my Salon water heater broke down and it couldve cost me thousands of dollars but instead they fixed the problem without rebuilding the whole unit. These guys know their stuff well.

Hi Billy - There are no shortcuts to building a world class service first team. We pride ourselves in solving problems and presenting solutions with integrity. A rebuild or replacement may not be the best course of action. I will make sure to share the positive feedback with our team.

First String has been our plumber for years. They have done small fixes as well as large projects including boiler replacement and full bathroom remodel. They are equally responsive no matter the size of the job. Every technician is knowledgeable, thoughtful and friendly. Cannot speak highly enough about them.
