What Clients Say
Don't take our word for it. Here's what people in Ottawa have to say.
"We had Nick replace our faucet that had been leaking. He was easy to get in contact with, was able to give us a quote and schedule the job for a time that suited our schedule. We are very happy with the work he did. We would definitely contact him in the future if we require further services."
"Would absolutely recommend Nick to anyone looking for any type of plumbing work. I had him install a dishwasher for me and he was professional, efficient and did a great job. I'm definitely going to be calling him any time I need work done, and would recommend him to anyone I know."
"Knox plumbing went above and beyond for our bathroom renovation. Nick was professional, efficient and very resourceful, coming up with solutions that suited the availability of resources in our area. His expertise was greatly appreciated in practically all parts of our renovation. Highly, highly recommended."
