How Radon Abatement Works

The greater Portland Oregon metro area has some of the highest radon gas levels in the country. The goal of radon abatement is to trap radon before it enters your home and to give it a path to escape harmlessly into the open air.  Here’s a look at how it works.  

Radon gas is formed in the earth’s crust. It comes into your home through the easiest path possible.  Usually through cracks and openings in the slab, foundation, sump pumps, and crawlspaces.  Another way that radon gas enters a home is through older floor drains not equipped with a trap. It can also enter through collection pits for water overflow, that look like floor drains, but they aren’t attached to any type of plumbing. See picture.

Next, we build a system to draw the radon gas out of the home. Many companies use inexpensive thin wall Schedule 20 PVC pipe. We only use the strongest, most durable  Schedule 40 PVC or ABS piping to suck the radon out of your home. Our systems are designed to be so long-lasting that they come with a “Double Lifetime” guarantee that extends for as long as you own the home… and the next owner.

Radon gas WILL enter your home. A radon abatement system determines where the gas will go. We core a 6″ hole in the slab and then remove up to 15 gallons of dirt from underneath the slab. The amount of material removed might be the single most important step that’s taken. Most mitigators don’t go to this much effort and make up for it with a larger, noisier fan. They then offer an inferior performance guarantee of up to 4.0 pCi/l. By creating a huge”suction pit” under the slab, it gives the radon a place to collect. Our unique abatement designs allow us to offer industry-best performance guarantees down to 0.5 pCi/l.

A radon abatement design is like building an enormous vacuum. We seal the suction pipe into the suction pit. The pipe is then routed to a high-performance radon fan that’s installed outside. (we use sound dampeners at every connection to the house). Additionally, we seal EVERY crack we have access to. Radon can enter a home through a small crack like a fire hose. If you have a finished basement we’ll use our FLIR E8-ET Thermoscanner to search for cracks under the carpet so we can seal any cracks found there. Carpet won’t stop radon gas. Our FLIR scanner will save you the expense of having to pull back the carpets to find those pesky slab cracks.

Every company has a choice of fans to use in their installations. We use the best: PERIOD. Our fans are the quietest, most efficient, and longest-lasting fans available. They’re made in America and come with a 10-year warranty. Every other company offers a 5-year warranty on their Chinese fans unless they charge you more. Our high-efficiency radon fans create a vacuum that draws the concentrated radon gas up and safely away from your home 24 hours a day, 7 days a week… for decades. A JustRadon.Com radon abatement system adds value to your home.

  • Initial inspection was very professional and Lawrence gave us a variety of options where we could place our radon mitigation system. He told us exactly how the process worked and what to expect. We couldn't be happier with the finished product. Great Work!

  • Just Radon installed a top of the line radon reducer system in my basement. It is quite and the company went the extra mile to make sure everything was done the right way the first time. They also replaced some pillars in my basement at a very fair price. When I look over at the radon system my neighbors have, I am so glad we had Just Radon install ours. It isn't an eyesore in the basement or on the side of the house, in fact if just kind of blends in. I would 100% recommend just radon to friends and family, the company did not disappoint.

Just Radon installed a Radon system in a home I was selling. They returned my calls and emails, talked me through the process, and provided a nice looking system. Another bidder was going to put the system in full view of people driving up to the home. Just Radon was much more thoughtful about where the system would be located so that it would be out of view. Piping was tight to the house and well installed. I would highly recommend Just Radon.

My grandson told me about radon and said I should have my home checked. He researched and found this company with a discounted price for the test. They came right out and placed their equipment. The gentleman was very polite and informative. When he came back a couple days later I was happy to learn that my home had very low levels of radon. He said there was nothing for me to do at this time but I should check it every couple years. I would recommend this company and the nice fellow who came out.
