I wouldn't hesitate to use Tony again. He came to our house at short notice and fixed various problems including our too-hot hot water. He was kind enough to call back the next day and see how things were going. Since our boiler had been installed in a strange, unconventional way, he came back the next evening to get to the bottom of the mystery. He's great to work with, very knowledgable and reasonable to boot. He also has the best name in Peckham plumbing: Only Flues and Horses.
