Robert responded quickly to our contact and arrived with his mask on; we did not have to request that. He listened carefully to our description of what we had already tried. (Before coming, he had offered to let us buy the parts ourselves but we did not trust that we would get the correct sizes.) In the bathroom, our hot water tap over the sink was running continuously. In the kitchen, there was a pinhole leak in the faucet and another leak in the drainpipe below the sink, which we had been tolerating for some time, partly because our tap design is unusual and we could not find a replacement. Robert diagnosed the problems, phoned some suppliers, went and got the parts (phoned to say that one supplier was farther away -- ok with us), and finished the repairs. We were impressed with Robert's competence and friendly business-like manner.
