Over the past couple of months, I had a loud pipe hammering noise every time I flushed the toilets, did laundry or turned on and off a cold water tap. It was annoying. I called WaterWorks and Michael came by for an assessment, quickly isolated the problem, explained why it was happening and how to fix it. He was very professional, did not rush through any explanations. I booked the work and the following week Aaron came by to complete fix the issue. Aaron was very professional, courteous and he explained the work. He did not rush through anything and took every care. His work was excellent, the noise is gone. These guys are friendly, respectful, clean and honest. Thank you for the excellent customer service.
