Radon is a naturally occurring, oderless, tasteless, colorless, radioactive gas. Below are common questions and answers about Radon and why it is such a danger to human health. Please visit the Unites States Environmental Protection Agency’s Radon website https://www.epa.gov/radon/ for more information about Radon.

Where does radon gas come from?

Radon is everywhere. It’s part of the Earth’s crust. It occurs naturally from the breakdown of uranium. Uranium breaks down to radium, which breaks down to radon gas, which then rises out of the Earth’s crust. The reason people say and believe that there’s no radon in this area is that the area hasn’t been tested for radon. The only way to know how much radon is in a particular area is to have it tested. Radon levels are not static. They can and do change as the Earth’s crust changes. There are millions of seismic shifts every day across the planet, most of which are imperceptible, but even an imperceptible change in the earth’s crust can be enough to alter the path of radon gas.According to the EPA, radon is responsible for 21000 lung cancer deaths every year. That’s why they recommend testing your home for radon every two years. To get started with radon mitigation Portland, OR homeowners trust, call our team today.

Why is radon gas dangerous?

Radon gas is dangerous because it’s radioactive. The half-life of radon is 3.8 days. As it breaks down, it gives off explosive alpha particles. When radon gas is inhaled, it attaches to the lung tissue. As it continues to break down inside the lungs, the release of the alpha particles can damage the DNA. The damaged DNA can then mutate into cancer. This risk of radioactive radon gas applies to every living thing that’s exposed to it.

How do I test for radon gas?

You can have your home tested by Just Radon with a Continuous Radon Monitor (CRM). It’s the type of monitor that’s used in real estate transactions. The cost is $150 and the process takes two days. However, you can also use an activated charcoal test kit that can be purchased at most hardware stores like Ace, True-Value, Lowes, and Home Depot. You can also buy them online. They cost around $20 and need to be mailed to a lab for the results. Activated Charcoal test kits can be very accurate when the instructions on how to use them are followed carefully. You can purchase a short-term kit from Just Radon for $20.63 which includes shipping, handling, and lab fees. The results of your test will be available online in approximately 3 days. If your radon test comes back positive, call us for effective radon mitigation Portland, OR homeowners count on.

What do I do if my home has high levels of radon gas?

There is no safe level of radon. If you feel the radon in your home should be lowered, call us for a free proposal on radon mitigation in Portland, OR. Our systems and innovative installation techniques reduce radon to the lowest levels. We guarantee radon levels to reach about half of what our competitors can do. We consider the age of the home, the geology underneath it, and the home’s construction to design and install an effective and efficient radon abatement system specific to your home. It’s been said that there are only two types of radon abatement systems: Just Radon systems… and all others.

How much does the radon mitigation system typically increase an electric bill per month?

It depends on the fan and your local energy costs. Radon fans consume 60-170 watts. They use the same amount of electricity as a conventional light bulb of the same wattage. As an example, a 100-watt radon fan at 11 cents/KWH would cost $8.03/month to operate. The same amount of a 100-watt light bulb if it was never turned off.

What is the noise/sound rating for the radon fan?

There is no sound rating for radon fans. All radon mitigation systems generate some noise. Any sound created depends on the size of the radon fan required. The size is determined by the soil under the home, the size of the suction point that’s created, and the method of installation. Dense clay soil under the home may require a fan with blades designed to create more suction, which may create more sound. Every Just Radon mitigation system comes with sound dampeners.  Adding a custom sound suppressing fan cover reduces the sound by 50%, and extends the fan warranty to 10-years. A Just Radon mitigation system is the quietest available. To learn more about our systems for radon mitigation Portland, OR homeowners use, call today.

How loud will the system be in the house?

The city of Portland has a sound ordinance that the fan should not exceed 50 decibels at the property line. From inside the house, it would be incredibly quiet if not imperceptible in a normal environment. No one can determine in advance what the sound level will be prior to installing the system.

How loud will it be for my neighbors?

From inside your neighbor’s home it would be incredibly quiet if not imperceptible in a normal environment. It depends on the proximity of the neighbors home to the radon system in general and the proximity of windows and doors of the neighbor’s home to the fan and the vent pipe exit specifically. The sound level can’t be determined prior to installing the system.

How big is the penetration into my basement floor? Do you reseal?

The slab core would be 5-6” in diameter. We excavate up to 15 gallons of material through the slab core. A suction pipe is sealed into the opening with an airtight closed-cell backer sleeve. We then seal it with polyurethane caulk or concrete over the sleeve to form a durable airtight seal.

Can the vent pipe be close to a window or a door?

According to the EPA exhaust pipe exits of a radon system must vent above the surface of the roof and 10 feet or more above the ground. They must also be at least 10 feet away, or 2 feet above, windows, doors or other openings that could allow radon to reenter the home. For homes with high walls the vent pipe does not have to be above the roofline as long as the vent is 20’ above the ground. 

What is the 12-month radon test required for the homeowner to provide to determine if the radon levels exceed the guaranteed radon level?

It’s a long term activated charcoal test kit. They cost about $40. However, Just Radon performs a post-abatement test 24 hours after the system is activated. If the initial results are not what we expected we’ll make system adjustments. Any adjustments after that will require a long-term test. Our systems improve over time.

I want to confirm that Just Radon is responsible for any damage that might occur during the job and cleanup after the job?

In the unlikely event that any damage is caused in the course of our system installation we would take 100% responsibility. We thoroughly clean up after each job.

How do I schedule the inspection after installation?

We automatically conduct a post abatement test upon completion. The EPA states that the test cannot be started sooner than 24 hours after the system is activated or more than 30 days. We use the same CRM used to measure radon in real estate transactions. This $150 test is included in our proposal price.

It seems that air is coming through the vents into the house from the basement which I assume is bringing radon from the basement into the main house. Is there a way to help mitigate this? Or will installing the radon system in the basement reduce levels?

The sub-slab depressurization system we install would abate the radon in the basement which in turn would prevent it from reaching the main floor through the basement HVAC system.

Are the radon levels in the rest of the home likely lower than the basement? How much does this typically differ?

Radon is the heaviest gas on earth. It’s 8X’s heavier than air. Unless you have radon in your water, or radon is being distributed through the HVAC system it’s unlikely the radon in the upper levels will be higher than the level in the basement. 

Please explain the double lifetime warranty. What are you guaranteeing for this time?

We’re guaranteeing the radon levels to be equal to or below our guaranteed level for as long as you own the home and the next owner. Double Lifetime.

How did these calculations for the system cost and radon level guarantee come about? Why are they so different for me vs. another customer?

Every home is different. The cost for a sub-slab-depressurization system involves the location of the suction pit in the home, age of the home, geology under the home, proximity of power to energize the fan, window and door openings to route around, condition of the slab, existing radon level, presence of a sump pump and/or dewatering system, framing of the home, whether the walls and ceiling are finished, proximity of neighbors, the height of the home, the height of the neighbor’s home, etc. The list goes on. That’s for a sub-slab radon system. The levels you’re reading about on our website are not the guaranteed levels, they’re the levels we achieved. We can guarantee the lowest radon levels with a sub-membrane-depressurization system (crawlspace) but they’re more expensive relative to sub-slab systems.

Your guarantees vary widely from your competitors. How can you provide a double lifetime warranty, 10-year fan warranty, guaranteed radon levels below 1.7 etc?

Unlike other companies we do not provide a proposal without first visiting the property. We conduct a thorough survey. The unique characteristics of the property are noted, pictures are taken, geological maps are reviewed. If needed we use a FLIR thermal camera to find hidden cracks and a CT007 Radon sniffer to identify radon entry points. With that information a custom proposal is prepared. 

 Our system designs and components are well thought out. We don’t use cheap Chinese fans like our competitors. Our fans are the quietest most durable available. They’re made in the USA with the best German Pabst EBM sound dampened electric motors. Our attention to detail, and our unique and proprietary installation techniques, allows us to offer the most comprehensive warranties and guarantees in the nation.

What’s the big deal between 2.7 pCi/l and 1.7 pCi/l? That doesn’t seem like much to worry about.

The difference of 1.0 pCi/l of radon gas in the air you breath is equivalent to each man, woman, child, baby, dog, and cat in the house smoking over 36 packs of cigarettes a year… every year. It’s also equivalent to getting 50 chest X-rays each year. Radioactive gas is a big deal.

When you say sound dampening included, can you explain what falls under this category?

Our agreement states “Unless specifically stated, no additional sound reduction methods are included”. Sound dampening straps are included in every proposal. A vent muffler is not included which is an additional $200-$350 depending on the type of muffler and the installation. Mufflers are rarely needed.

How are you going to power the system?

Power is drawn from an existing outlet or tapped into an existing junction box. A dedicated circuit is not necessary. The system only draws 40-170 watts of energy like a light bulb.

Will you be using a roof flashing?

Yes. If there’s an eave we can get the vent pipe through we’ll use a roof flashing. If there’s no eave, we’ll run the vent pipe around the edge of the roof. Going through the eave presents a more finished look.

What is a manometer gauge and is it included with the system?

Yes. A manometer or a minihelic gauge is used on every installation as per EPA protocols. They are used to indicate system operation and fan capacity. They do not reflect radon levels. 

How long does a radon mitigation system typically last?

A Just Radon mitigation system lasts for decades. It’s the reason Just Radon stands behind their systems with a Double Lifetime Guarantee. To learn more about our process for radon mitigation Portland, OR residents use for decades, call us today.

How much time is needed for the job?

It will take 16-40 man-hours. It depends on the type of job and the time of the day we start. We usually finish in one day.

Where is the fan placed?

The fan location is specific to the property but cannot be in a living space or adjacent to a living space. It usually goes outside but can also be in an attic space.

What is required for a deposit; and when is payment due in full?

TNo deposit is required. Payment is due in full after the post abatement test, or 7 days from system activation, whichever is sooner. If the installation is part of a real estate transaction there’s no out of pocket costs. We’ll submit our invoice to be paid at close of escrow.

What payment methods do you accept?

Cash or check.  A credit card can be used but will incur a 3.15% convenience fee added to the invoice. 

Will a radon mitigation system reduce the humidity and other smells in my basement?

Cash or check.  A credit card can be used but will incur a 3.15% convenience fee added to the invoice. 

Can you provide references?

Testimonials from many of our customers and real estate brokers can be found on our Google Business reviews.

What areas do you serve?

We serve Oregon & Southwest Washington. For areas located more than 1-hour from 97034 there will be a trip charge.

How much does a radon mitigation system cost?

Radon mitigation system costs vary from $900 to activate a passive system to over $10,000+ for installations in large homes requiring multiple active systems. The average cost for a comprehensive Just Radon mitigation system is around $2,500. That would include the lowest radon level guarantee in the nation (about half our competitors’ guarantee), a 10-year fan warranty, a protective fan sound cover, full sound-dampening components, and a double lifetime warranty.Other systems available from our competitors cost about $2,000. They provide radon level guarantees that vary from 2.7-4 pCi/l, 5-year fan warranties, 5-10 year system warranties, and no fan sound cover or other sound-dampening components.For more information on comprehensive radon mitigation Portland, OR residents love, contact our team today.

How long does it take to install a radon mitigation system?

It depends on the type of job. Whereas other companies use one person to install a system, Just Radon uses two- to four-man crews on our radon mitigation installations. A sub-membrane system that requires encapsulating a crawlspace is labor intensive and takes longer to complete. Sub-slab and outside lateral foundation radon mitigation systems are completed in one day. Before we install your system for radon mitigation in Portland, OR, we will give you an accurate estimate of the time your project will require.

Where does a radon mitigation system go in a home?

A radon mitigation system location is site specific. The fan location cannot be in a living space or next to a living space, and it is most often located outside but can also be installed in an attic space. The suction point depends on the layout of the home and is uswhy chooually placed in the least obtrusive place possible, like in a storage room or a closet. Whenever it’s possible, we’ll design the system to be completely outside by coring laterally through the foundation under the slab. Then we’ll create the suction point through the foundation core. For more information on unobtrusive radon mitigation Portland, OR homeowners love, call us today. We’ll make sure you can be comfortable in your home once your system is installed.
