We proudly provide radon mitigation services for the Dundas, Ancaster, Hamilton and Burlington areas

At Radon PI, we're more than just a business, we're a family eager to help other families based on our own experience with radon testing and mitigation. Our journey began when our home's radon test result showed excessive levels that needed urgent mitigation.
As we searched for certified radon professionals in our area, we quickly found there were only a limited number.
Based on this experience, Radon PI was created and has been certified with the C-NRPP (Canadian National Radon Proficiency Program) since 2018. Radon PI is committed to excellence and dedicated to serving our customers. We take pride in providing high-quality radon measurement and mitigation services. Our goal is to reduce the radon level and help make your house a healthier home.

At Radon PI we stand behind our workmanship and prioritize customer satisfaction. We're dedicated to delivering high quality results that exceed your expectations.
Our mitigation guarantee includes lowering the radon level in your home to below the Health Canada standard of 200 Bq/m3. Following the mitigation installation, the radon level will be measured with a certified continuous radon monitor to prove that the system installed is lowering your levels adequately.
We’re very happy with the mitigation work undertaken by Radon PI. Darius provided a clear explanation of what was needed, and a clear quote and timeline for the work to be done. The pump installation was done quickly and with the minimum of disruption, and clean-up was excellent. Our radon levels have dropped to negligible amounts. The project was on time and on budget. I highly recommend Darius and Graydon from Radon PI.

Stellar installation with exceptional workmanship. Prior Radon reading of 450 has been mitigated to 28. Darius and his son are very knowledgeable, professional and totally dedicated to the satisfaction of their clients. Highly recommended +++++

We recently read an article by CBC News reporting on Radon Gas present in Canadian homes. We have never heard of Radon Gas or that it is the second leading cause of lung cancer behind smoking. The following day after reading the article we purchased a Radon Monitor and over the period of one week the readings varied from a low of 150 Bq/ m3 to a high of almost 300 Bq/ m3. The Canadian government recommends a level of 200 Bq/ m3. which is higher than other countries and the World Health Organization, which recommends 100 Bq/ m3.
We contacted a number of radon mitigation companies. We decided to have Radon PI do the radon mitigation for our home. Darius, of Radon PI was very thorough in explaining how radon enters the home and how it can be mitigated. Darius also explained the specific mitigation system that would be required for our home due to its construction.
The mitigation system was completed in less than one day and during the whole process Darius and his son explained each step. Since this was all new to us, it was appreciated that they took the time to do this. When they were done, they carefully cleaned up the areas where they worked, which was also appreciated.
Within 24 hours of the radon mitigation being installed, the radon levels were below 10 Bq/ m3 and and after the first day, the levels have ranged from 14 Bq/ m3 to 0 Bq/ m3 since the radon mitigation was installed 12 days ago.
I would not hesitate to recommend Radon PI to anyone looking for a radon mitigation system for their home.

Radon PI was excellent to work with throughout the mitigation process. My particular house came with some complications due to its age. I had inquired about mitigation with several companies who refused to take the job for this reason. Not only did Darius do a great job, he was extremely communicative throughout the process. At the time I was working on an unrelated project near the site we would be installing a mitigation system. Darius helped to educate me on multiple ways I could complete this project to make the mitigation system more effective as a whole. He took the time to offer his guidance on this separate project on multiple occasions. Good people who do good work. Cannot recommend highly enough.

“Darius and Graydon exceeded our expectations across the board! They were very professional, and took the time to explain the process and
equipment to us, which put our minds at ease. They were thorough and produced a system that worked well for our specific situation, and most importantly, they reduced our radon levels well beyond what we had hoped for! We would recommend Radon PI without hesitation!
Jenna, Burlington Homeowner
A big thank you to Radon P.I. for addressing the Radon situation in our basement. The radon level was shockingly as high as 800 Bq/m³. After the mitigation system installation, we are getting 3-20 mBq/m3. The system was installed in a single day with minimum disruption and zero mess. The whole experience was simple and straightforward. Highly recommend.
DAZ, Oakville Homeowner
"Our home just went up in value! Radon is everywhere and homes have different levels of it. Our levels have just improved from 550 to approx. 20! We have a solid and approved system, super quiet, and data to show any prospective home buyer. The entire process with Darius was fantastic: initial free quote, education, installation was actually dust free! It was a pleasure to watch Darius and son as work team do the entire install in a few hours. We are so happy and relieved to have a safer home."
Monique and Steve, Dundas Homeowners
"The Radon P.I. team was wonderful to work with from the initial consultation, the installation and the follow up monitoring. They were thorough in their assessment and made sure we understood what was going to be done before moving forward. We have a successful mitigation that is working extremely well. Our thanks to the whole team."
Franca, Mississauga Homeowner
"We felt that Radon P.I. was a great company to deal with. They came on time, cleaned up and followed up. We were very pleased with every aspect of the job. Darius explained the whole process thoroughly. His quote was exact, no surprises. I would highly recommend Radon P.I. to anyone."
Brenda, Ancaster Homeowner
"I was very happy with Radon P.I. The quote was accurate, they came when they said they would, did the installation in a timely manner and cleaned up afterwards. The location of the installation was well thought out and clearly explained to me. Installing a radon extractor is one of the few things we can do once, and it improves the quality of the air in the home for years. I feel it adds to the value of a property, it is a clear indication that the homeowner cares about the quality of their home environment."
Penny H., Dundas Homeowner
"Deborah and I were very pleased with your installation. We went from a high radon count to minuscule, as a bonus, our basement went from damp to dry, the work was done well. Darius is a delight to work with and it all came in on the quoted price."
Paddy D. Dundas Homeowner
"We recently tested for radon and discovered very high levels in our house. Radon PI installed a mitigation system for us on short notice. Darius and his son were knowledgeable, helpful and professional. The installation took one day, was without dust or mess and our radon levels plummeted to well below safe levels."
Jonathan, Greensville Homeowner
"Radon PI did a great job installing our mitigation system. After self monitoring our radon gas levels for the past 2 years and researching the associated risks, we finally decided to take action. Radon PI clearly explained how the system would remove the radon gas trapped in the gravel between the clay soil and the basement floor. Our levels are now very low and our risk of lung cancer has been greatly reduced. We only wish we had done it sooner."
