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If your existing mitigation system is outdated or ineffective, we offer system upgrades.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.

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!Posted on 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.Posted on Google![]()

Great experience with John The Plumber for a second time, different issue. Received10% discount as a returning client. 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.Posted on 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.Posted on 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 youPosted on Google![]()
