Why Radon Repair

Radon can be confusing. We make it simple.

A high result is stressful, and there's a lot of conflicting advice out there. Think of us as your radon agent: we explain your number in plain language, fix what needs fixing, and stay with you long after the install.

Honest advice, even when it costs us the job.If your level is only slightly high and a simple fix might bring it down, like cleaning a blocked air exchanger, we'll tell you to try that first and test again.

1,000+ mitigations, from simple basements to crawl spaces, augering and trenching
Big buildings too: commercial buildings, including schools and public buildings
The complex ones: additions, crawl spaces and mixed foundations are where our building-science background pays off
Local since 2016: our Moncton team has been serving homeowners across the Maritimes
Inspectors at heart: owners Jeff LeBlanc and Doug MacDonald are Certified Master Inspectors, with 8,500+ home inspections behind them

Three steps to lower radon

1Book your free consultation

We start with a quick virtual consultation. In Greater Moncton and southeastern New Brunswick, we also offer in-home consultations, and anywhere else, we’ll visit when your home needs a closer look. We explain your results in plain language, set expectations and give you a clear quote.

2We design and install your system

First, pressure field extension (PFE) diagnostics: we measure how air moves under your slab. Then we design your system around those readings and install it, usually in a single day.

3We monitor, maintain and guarantee it

Every system we install includes the first year of Radon Shield™ MONITOR: 24/7 EcoGuard monitoring, monthly reports and alerts to our team. MANAGE adds our yearly 21-point system inspection.

What that means in your home

Quiet

We design every system, and use every part we can, to keep noise and vibration as low as possible.

Clean and respectful

On time, floors protected and no mess left behind. We work with your basement finishes and future plans, and we only drill where you've approved in advance.

Designed for your house

We measure how air moves under your slab before we design anything.

Energy-efficient install

Fantech EC fans let us dial in the right suction for your home, keeping heat loss and backdrafting to a minimum. They can be adjusted later if things change.

Built to last

Radon-specific pipe and materials, installed to meet or exceed CAN/CGSB-149.12, the national standard C-NRPP trains and certifies us on.

Monitored and guaranteed

So you never have to wonder.

More than car accidents (1,898), carbon monoxide (300) and house fires (109) combined.

90%+Typical reduction, for the cost of a common home improvement

Health Canada: mitigation typically lowers radon by more than 90%, at a cost similar to other common home improvements.

One system instead of three

Excellent experience! We have a large bi-level split with a basement, slab-on-grade, and living space over the garage, so we expected to need three radon mitigation systems. The technicians skillfully installed a single system into the weeping tile, which communicated beneath the entire house, eliminating the need for the other two systems. The result was a 98% reduction in radon levels throughout our home, along with significant cost savings. Professional, knowledgeable, and highly recommended!

A complicated case, solved

Radon Repair were great from start to finish. We had a somewhat complicated case, and they did not stop until they had it figured out and our radon levels successfully reduced. Every single team member was knowledgeable, professional and friendly. Thank you Jeff and all the team at Radon Repair!

A detailed plan and quote

They did a thorough video walkthrough of our property and gave us a detailed plan and quote. An appointment was booked and Robert and Austin showed up on time and prepared. … We had an 85% reduction in radon levels in 24 hours and remain well below guidelines. Great job and highly recommended.

Angela's Promise

Why we do this

Angela, of Havelock, NB, called us after a Stage 4 lung cancer diagnosis. Her home tested well above 10,000 Bq/m³, with spikes to 20,000. Angela's wish was to create more awareness, so more people would test and fix their homes. Our in-home radon education and testing service carries her name.
