 Trustindex verifies that the original source of the review is Google. In Ottawa Canada, Carson did a great job of installing a new toilet as well as taking away the old one. All at a reasonable price.
We discussed the type of toilet I wanted, he went out and bought the toilet, he installed the toilet and took away the old one.
He was fast and efficient and did a great job at cleaning up afterwards.
Great Job Carson! Thank you very much!
And thank you to John The Plumber!

 Trustindex verifies that the original source of the review is Google. I chose to go with John the Plumber because of their reviews online. Originally, they tried pawning off the job a few hours before the scheduled appointment to a sister-company because they had an emergency come up.

I decided to move the date to accommodate the scheduling conflict and so I could keep John the Plumber as the provider of the service.

Matt (plumber) was great! Very personable, knowledgeable and did a great job identifying the issue and fixing the problem. I will definitely reach out for future plumbing issues.

Elia showed up at expected time and provided fast, friendly and efficient service which was also my experience with their first visit 2yrs ago repairing pipes. He left everything clean and informed the work is warranteed. Elia also took time to explain details to help prevent the problem from recurring which was truly helpful.

 Trustindex verifies that the original source of the review is Google. Thank you, plumber Justin, for your excellent work, advice and positive client experience! Justin showed up on time and didn't leave until everything was fully fixed. He was professional, super friendly and gave good advice. I was able to get an appointment within a day to deal with a waterline when my old fridge broke down after 24 years. Justin also took care of a shower issue that I asked him to look at and he took the time to deal with that. I always call John The Plumber whenever work needs to be done at our house, because they are responsive and reliable. Their plumbers consistently impress me with their friendly and positive attitude on top of their high quality work.

 Trustindex verifies that the original source of the review is Google. I had a great experience with Owen.
He was on time, got to work immediately, told me about my options after he finished his initial inspection and about the price. Owen was professional, knowledgeable and caring about doing his work.
I recommend John The Plumber and I will use them for any future repairs or installation.
Thank you

If the issue is minor (like mineral buildup or an O-ring problem), repairs may work. But if the valve is old, leaking, or malfunctioning, replacement is the best option.

How much does a mixing valve replacement cost in Ottawa?

Costs depend on the type of valve, installation complexity, and parts needed.
