Radon is an radioactive inert gas produced by the natural breakdown (decay) of uranium in the soil. Radon is usually found in igneous rock and soil, but can also be found in well water.

Radon gas is breathed in and out without "sticking" to the lungs, but it does cause damage while it is in your lungs. Radon "decay" emits alpha particles that is hazardous to the lungs. Radon is the second leading cause of lung cancer.

The EPA's action exposure limit for Radon is 4pCi/l - which means if your house is tested and is above that level, you should take action to reduce the Radon concentration. Radon is a national environment health problem, high Radon levels have been discovered in every state.


ARMS Radon was established in 1994 and is a licensed and fully insured company serving the northern Illinois area.

Houses with basements, crawl spaces, slabs, or a combination of foundations have all been successfully mitigated following Illinois/EPA requirements.

Whether the radon level measures 4.0 pCi/L or 50 pCi/L, ARMS Radon’s goal is to reduce levels as low as possible by routing an aesthetically pleasing system and keep costs as low as possible.



ARMS Radon is an experienced professional radon mitigation provider that offers the following services:

Active radon reduction system using the subslab depressurization technique.

Pre-piping homes during new building construction for future radon systems.

Sealing access points which include the sump pit and cracks in the floor, wall, and perimeter to reduce the flow of radon.

Sealing the crawl space with a high-density plastic membrane.

Upon request of the homeowner, install or replace a sump pump and/or back up sump pump.

We also offer home repair work and other projects, (ie: plumbing, electrical, remodeling…). Please call for details.



A consultation that includes answers to any radon questions, an explanation of the mitigation system, and a quoted price. *A free written estimate with a detailed description stating the scope of work, guarantee/warranty, and cost is available upon request* No surprises!

Starts upon completion of installation and extends for a 5-year period for whoever owns the property.

All active systems installed will carry a 5-year guarantee that radon levels will not go above 4.0 pCi/l.

All systems also come with a 5-year warranty that will cover all components of the system as well as workmanship.

All fans installed by ARMS Radon come with a manufacturer 5-year warranty and are expected to last more than 10 years.

What is Radon?
Radon is a naturally occurring, colorless, odorless and tasteless radioactive gas. Radon comes from the radioactive decay of Uranium 238 and the immediate decay of Radium 226 in the soil. Much of the Radon produced enters the atmosphere, but the concern with Radon is when it accumulates in the home.

Why is Radon a concern?
According to the Surgeon General (January 13, 2005) “More than 20,000 Americans die of radon-related lung cancer each year.” This makes radon the number one cause of lung cancer among non-smokers and the second leading cause of lung cancer overall. The EPA recommends homes be tested every 2 years for radon and corrective steps taken if the radon level is 4.0 pCi/L (pico Curies per Liter) or more. Because there is no known safe level of exposure to radon, EPA also recommends that Americans consider mitigating (correcting the level) their home for Radon levels between 2.0 pCi/L and 4.0 pCi/L.

How do I know if my home has radon?
There are two ways to test your home for radon. This first is to obtain a device through the mail or Hardware store, deploy it in your home following the instructions and mail it to a lab for analysis. The second method is to have your home professionally tested and in most cases receive an on-site report showing your homes hourly pCi/L measurements.

What is Radon Mitigation?
The most common type of mitigation as Active Soil Depressurization. This system consists of PVC pipe that collects the radon gas from beneath the slab or a plastic liner (crawl spaces) and routes it to a special radon fan that vents it to the atmosphere before it enters the home.

What is the difference between an exterior routed system and an interior routed system?
On an exterior system, the suction point is located in the basement with the pipe exiting the home at the rim joist, attaching to a radon fan and the pipe discharging per EPA regulations. An interior system also has the suction point in the basement, but the pipe then routes to the attic space. The radon fan is mounted in the attic and discharged through the roof looking like the homes other plumbing vents. Every home is different and getting the pipe to the attic space can be either through the homes existing chase for the carbon monoxide flue, up the garage wall or through closets. Most homes have the option for either interior or exterior systems and ARMS always offers quotations for either system and a detailed description of locations of the pipe and fan.

What are the costs?
Most homes with a typical basement will cost about $1,300.00 for an exterior system and about $1,350.00 for an interior system. Homes with crawl spaces or multiple foundations generally will be in the range of $1,450.00 to $1,550.00 depending on several factors.
