IS Plumbing did an excellent job replacing our water heater and resolving several other plumbing problems during the same visit. They located a leaking ice-maker shutoff behind the kitchen cabinet, removed the unused ice-maker line, replaced the old piping connections, and fixed our leaking bathtub and shower valve. They were professional, thorough, and left everything clean after completing the work. We were very happy that they were able to take care of so many issues in one day. Highly recommended!
We had an issue with our boiler that left us without hot water, and Ilan from IS Plumbing was absolutely fantastic. He was prompt, reliable, and honest throughout the entire process. He went above and beyond to track down the parts we needed and made it a priority to get everything repaired as quickly as possible. He kept us informed, followed through on everything he promised, and genuinely cared about getting the problem resolved. It’s rare to find someone this dependable and committed to doing the job right. We’re incredibly grateful for his help and highly recommend Ilan and IS Plumbing!
IS Plumbing responded quickly when my shower had only hot water. They came the next morning, replaced the shower valve cartridge, adjusted the temperature, and everything works perfectly now. Professional, reliable, and efficient. Highly recommend!.
