Our Plumbing Services Include
Emergency Plumbing Repair
Dealing with a plumbing emergency can be a nightmare, especially if you can’t find plumbers who are available in the evenings, on Saturdays, or on Sundays. It would be great to have a convenient plumbing company that charges standard rates for off-hours services, wouldn’t it?
At John The Plumber, we understand how stressful plumbing emergencies can be, which is why we’re proud to offer Saturday and Sunday plumbing services. We’ve even found plumbers in St. Catharines who enjoy working on the weekends, which is quite a miracle! So, if you need emergency plumbing services on the weekend or during the evening, don’t hesitate to call us. We’re your go-to emergency plumber near you that can help today!
Leak Detection
A water leak can cause significant damage to your home, including rot, mold, puddles, and water droplets on your head. If you’re dealing with a water leak, don’t hesitate to call us. At John The Plumber, our expert plumbers can run a plumbing investigation to locate the source of the leak while minimizing damage to your home. Once we find the leak, we’ll repair it on the same day.
Faucet Repairs and Installations
A new faucet can give your kitchen or bathroom a fresh look. However, if you’re dealing with a leaky faucet or some other faucet issue, it can be frustrating. That’s where we come in – at John The Plumber, we offer plumbing repairs on faucets, install customer-supplied faucets, and supply and install faucets.
If you choose a faucet supplied by us, you’ll enjoy a 2-year warranty to protect your investment long after the installation is complete.
Bathroom Rough-In
A plumbing rough-in is the installation of water supply and drain pipes without the fixtures. Rough-ins are a necessary step when adding a bathroom to your home or completing a bathroom renovation. At John The Plumber, we take our bathroom rough-ins very seriously. Our experienced plumbers will ensure that everything we do is up to code and completed at a high level, so you won’t face any related plumbing issues in the future.
We offer bathroom rough-in services for new construction, renovation, and remodeling projects. Our plumbers will work with you to understand your needs and ensure that your bathroom rough-in is completed to your satisfaction.
Blocked Toilet
If your toilet is clogged, the first step is to try using a plunger. However, if that doesn’t work, don’t worry – we’re here to help. At John The Plumber, we offer same-day clogged toilet repair services to help you unclog your toilet when you need it. We come equipped to auger the toilet, clean the drains, and do any other drain services you require.
Clogged Sink
Your kitchen sink and bathroom sink drains are designed to handle water, and introducing substances other than water and soap can lead to blocked drains. Unfortunately, clogged sinks are often caused by grease, fat, food, hair, and other substances that can be difficult to avoid putting down the drain. Kitchen sink clogs are some of the most stubborn and difficult to deal with, due to the nature of grease.
If you have blocked sink drains, there’s a good chance that we’ll need to manually clean them with professional sink drain services. At John The Plumber, we’re equipped to handle all kinds of clogged sinks, and we’ll have your sink back to normal in no time.
Sewer Cleaning
If you’re dealing with sewage backups in your home, you likely need to clean your sewer pipes. All the sewage in your home flows through your sewer lateral, and if it’s blocked, none of the sewage waste will have anywhere to go. This can cause sewage to back up into your home, leading to unpleasant odours, damage to your home, and even health risks.
The good news is that you likely don’t need to excavate your lawn and replace your entire sewer pipe, although sometimes this is necessary. At John The Plumber, we use mighty sewer rooter machines, powerful hydro jet drain cleaners, or herculean chain knockers to clear just about any blockage. Different sewer blockages require different tools to resolve the issue, but don’t worry – we have all the equipment needed to get the job done.
Appliance Installation
Purchasing a new appliance can be exciting, but the installation process can be daunting if you’re not familiar with plumbing connections. That’s where John The Plumber comes in! We offer appliance installation services for refrigerators, dishwashers, and all other appliances that require plumbing connections.
If you’ve recently purchased a dishwasher or refrigerator and need help with the installation, we’re happy to help! Our experienced plumbers can ensure that your new appliance is installed correctly and safely, so you can enjoy the benefits of your new appliance without any worry.
