We had Chris and Jeff visited today for replacement of diverter and cartridge for our shower. Both were friendly, professional, and answered all our questions. Thank you, Chris and Jeff. Would definately recommend them in my circle.

Very positive experience. Quick response. Kind and attentive technician, Michael. Very gentle and professional in his explanations. Also very patient as I had to be on several calls working from home while he was attempting to perform the valve replacement and communicate with me. Sincerely valued this kind behaviour. Michael also ID’d a separate small ball valve leak and will come back to perform the valve replacement. He left a small basin to protect from any leaks. Really good.

Highly recommended using John the Plumber, the service was exceptional. I had issues with the main shut off value and the serviceman assisted me with dealing with the city and waited until everything was scheduled with the city and rescheduled their visit to coordinate with the city shut off. The work was done quickly and beautifully. 100% I’ll be recommending John the Plumber to family and friends.

Late on Monday afternoon, I managed to make an appointment for 8am Tuesday morning to have a leaking shutoff valve fixed. Jonathan arrived promptly just after 8, quickly resolved the leak and then stayed for the remainder of the appointment window changing other aging faucet cartridges and shutoff valves as a preventative measure. I was very pleased with Jonathan’s pleasant, personable approach as well as the diligent, efficient work done. I’ll definitely be a repeat customer whenever I need a plumber.

Outdoor Faucet Installation and Repair Oakville Plumber

Outdoor Faucet Installation and Repair

Oakville is no stranger to harsh, cold winters. If you don’t have a frost-free hose bib, there’s a reasonable chance that your hose bib will freeze during winter and it isn’t going to work when you turn it back on. A frost-free hose bib is an outdoor faucet that is built to drain when shut off. As a result, no water remains in the unit. Without water, you eliminate the risk of water freezing inside and causing damage. You would be amazed by how many homes experience burst frozen pipes in the winter due to their outdoor tap freezing. John The Plumber wants to do his part in helping you prevent this from happening, and helping fix it when it’s happened.

Sewer Backup in Morrison, Oakville,

Sewer Backup in Morrison, Oakville

The toilet was backing up. That is usually a sign the problem is further down than just a fixture drain. We see this a lot in Morrison. Older homes, established neighbourhood, and plumbing that has been working hard for decades.

We ran the main drain snake and used the camera at the same time. That way we could see exactly what we were dealing with, a blockage deep in the main line. No guessing, no hoping. Just a clear picture of the problem before we started clearing it.

Once we broke through the blockage, the line opened right up. Everything draining the way it should. The kind of result that is easy to take for granted until it stops working.

Sewer backups can get messy fast. The longer it sits, the worse it gets. A slow toilet or a drain that gurgles when it should not are worth paying attention to early. We can usually get out quickly and figure out what is going on.

If you are dealing with a backup in Morrison or anywhere else in Oakville, give us a call at 289-644-3856 and we will come take a look.

Whether it’s a small leak or a full-blown plumbing emergency, John The Plumber is ready to respond—fast. We offer same-day plumbing service across St. Catharines, delivered by licensed, experienced professionals you can count on.

Contact us today and see why so many homeowners consider us one of the top-rated plumbing companies in the region.
