Radon gas is a naturally occurring radioactive gas that can accumulate in homes, posing serious health risks. Health Canada recommends Radon testing and proper installation of a radon reduction system to protect homeowners from radon exposure. If high radon gas levels are detected in your home, installing a radon mitigation system is essential to reduce the radioactive gas and protect your lungs from long-term harm.

At John The Plumber, we specialize in radon reduction system installation in Ottawa, ensuring your home remains safe from elevated radon levels. Using advanced techniques such as active soil depressurization and sub-slab depressurization, our certified radon professionals design and install an effective mitigation system to remove radon from beneath your foundation. We take pride in delivering professional service with guaranteed results.
A properly installed radon mitigation system effectively reduces radon gas and improves indoor air quality. Our licensed specialists evaluate your home, perform a long-term radon test, and determine the most effective mitigation system based on your home’s construction joints, soil, foundation, and ventilation.
We install PVC pipes, hydraulic cement, backer rods, and ventilation systems to safely draw radon from the soil beneath your home and release it outside, lowering radon levels and preventing radon enters from occurring again.
If your radon reduction system is malfunctioning or failing to reduce radon levels, we provide 24/7 emergency radon mitigation services. Our team quickly inspects and repairs sucking air systems, pressure differential failures, and vent blockages, ensuring your home remains protected from radon exposure.
If your existing mitigation system is outdated or ineffective, we offer system upgrades. Whether it involves replacing PVC pipes, improving ventilation, or optimizing pressure differential for better radon removal, our certified radon professionals ensure your home is protected long-term.
Regular maintenance is also essential to monitor radon levels and keep your system operating efficiently. We provide long-term radon test services to ensure your home remains within safe limits.

We have dealt for the first time with Joh n the plumber and are very impressed with the service and ethical integrity that Brad their septic technician was. He took the time to explain and give us various options with our older septic system. I would recommend him and John the Plumber to anyone. Thank youPosted on Google![]()

Ryen and Jordan did an exceptional job addressing a kitchen sink that wouldn't drain. They were professional, hunted the problem until it was resolved, and then made a quick fix to help prevent the issue from reoccurring. Moreover, they quoted me for a proper longterm fix and weren't aggressive or pushy. They blew my expectations out of the water and I wouldn't hesitate with using them again in the future. I hope that their great work and friendly disposition doesn't go unnoticed by any higher-ups!Posted on Google![]()

I can't say enough good things about Matt and Elia from John the Plumber! Not only are they excellent problem solvers who really know their stuff, but they're also genuinely great people.

It's refreshing to deal with people who not only take pride in their work but also make the whole experience pleasant and stress-free. They went above and beyond, and their positive attitudes and dedication really stood out. I highly recommend Matt and Elia to anyone looking for reliable, knowledgeable, and genuinely caring plumbers. John the Plumber is lucky to have these two on their team!

Had Tomas and his team come in to install a new sump pump pit system with backup. They did a fantastic job. They kept the worksite meticulously clean and kept me informed of all the steps as they happened. They accommodated a couple changes very easily and now I have peace of mind in case there is another flooding event. Would work with them again in a heartbeat
