First String Plumbing recently installed a brand-new boiler system for our six-family home, and we couldnt be more satisfied with the entire process. From start to finish, the team was highly professional, efficient, and extremely well organized. The installation was completed quickly with virtually no downtime, which was critical for a multi-family building.They carefully managed the transition from the old system to the new one, ensuring heat and hot water interruptions were kept to an absolute minimum. Communication was clear throughout the project, and the quality of workmanship was excellent. The new system is running perfectly, and the upgrade was completely seamless.We are very grateful to First String Plumbing for their responsiveness and expertisethey truly came to our rescue. We would highly recommend them for any large-scale or time-sensitive plumbing and boiler work.

We had an excellent experience working with First String and Henry Fischer during the construction of our new home with our builder Exclusive Homes. From the initial planning stages through final installation, their work was consistently professional, detail-oriented, and well coordinated with our builder and other trades.Communication was clear and timely, any questions or adjustments were handled quickly, and the quality of workmanship was outstanding. Everything was installed cleanly, tested thoroughly, and completed on schedule. Its clear they take pride in their work and understand the demands of new construction projects.We truly appreciated their reliability, expertise, and collaborative approach throughout the build. We would confidently recommend First String to anyone building a new home or looking for a skilled, trustworthy plumber.

Great and friendly service. Helped work out some complicated connections and trouble shoot various appliances. Highly recommend. They did my firepit, my pizza oven, outdoor kitchen, and ran extra gas lines
