Yes, American Radon Mitigation Inc. warrants materials and workmanship for five years. Our goal is to protect you and your family by reducing your radon levels as low as possible.

We also guarantee that your home’s annual average radon level will not exceed 1.5 pCi/L for five years from the installation date, provided all items on the bid are selected.

The 1.5 pCi/L guarantee does not apply to homes with sub-slab ductwork, aftermarket drain tile, untreated crawl spaces, multi-family homes, or inaccessible air leaks to the soil. The average outdoor radon level in Colorado is between 0.3 and 0.7 pCi/L. While it’s not possible to reduce indoor levels below outdoor concentrations, our average post-mitigation radon level is 0.4 pCi/L.

Yes. The key to getting your radon levels as low as possible is to create a vacuum under your entire home. American Radon Mitigation performs a thorough diagnostic process, often overlooked by other contractors, called Diagnostic Testing and Pressure Field Extension (PFE) Testing.

To test PFE, we establish suction points and drill a few small holes through the concrete floor in different areas of your home. We use a specialized gauge that measures pressure (vacuum) under the slab of your home to confirm we are creating suction in the right places to address all radon-entry points in your home. This means we’re not guessing where to place components. We’re using real data to design a system that works.

This process allows us to design and engineer a system that is efficient and tailored to your home.

PFE testing helps determine:

• The best location for the suction point
• Whether additional suction points are needed
• What size vent pipe to use
• What adjustments are needed to control pressure using valves on each suction point
• Which radon fan is the best choice for your home (we only use fans with high-quality German-made motors)

Fan placement depends on your property, but our typical order of preference is:

1. Garage attic: It’s less invasive, quieter, protected from outdoor elements, and aesthetically pleasing.
2. House attic: It’s protected from outdoor elements and aesthetically pleasing.
3. Exterior of the home: This is less desirable because it results in a shorter fan life, exposure to elements, is more susceptible to freezing up, and is not aesthetically pleasing.

We will never place a radon fan indoors. It is against code, and if the vent pipe or fan ever developed a leak on the exhaust side of the fan, it would pump high levels of radon into the home.

American Radon Mitigation can arrange for a licensed electrician to wire your radon fan, and they will pull the necessary permits.

Do not allow a radon contractor who is not a licensed electrician to wire the fan themselves. This could be a fire hazard, and your homeowner’s insurance may not cover any damage if a licensed electrician did not complete the work.

If the radon fan is in the attic, an outlet must be installed within 6 feet of the fan. If the fan is outside, all wiring is required to be protected in conduit, unless otherwise permitted by local code, and it should not be a plugged disconnect. Your radon fan cannot be plugged into an extension cord.

Sellers often pay closer attention to cost than quality when making this decision. Many do not keep the buyer’s best interest in mind. American Radon Mitigation is not interested in cutting corners to be the lowest bid, especially when it comes to your family’s health. We treat your home as if it were our own, aiming to reduce radon to its lowest possible level.

As the buyer, you can request that we install a personalized mitigation system in your new home so you can be confident in the air you breathe for years to come. Another option is to ask the seller to take some money off the price of the home so that you can install a quality radon mitigation system. 

Yes, American Radon Mitigation will provide a written estimate to be signed before work begins.

American Radon Mitigation uses environmentally friendly products that are virtually odorless, non-flammable, and low in volatile organic compounds (VOCs) whenever possible.

Yes, American Radon Mitigation uses only the highest-quality materials in all our systems.

For example:

• A majority of the radon fans we use have long-lasting, German-made motors.
• Schedule-40 PVC.
• Our sump basket covers are clear Lexan and can support the weight of an adult.
• All roof flashing carries a 10-year manufacturer’s warranty.

We only use high-quality schedule 40 PVC pipe. Many contractors use thin-wall PVC, which becomes brittle and cracks easily when cold.

We typically use a 4-inch pipe when higher air flow is required. For systems requiring high suction and low flow, we utilize 2-inch and 3-inch pipe.

Per radon mitigation standards, the exhaust pipe must vent:

• At least one foot above the roof
• Ten feet above the ground
• Four feet above any window within ten feet

This prevents high radon concentrations from re-entering a building or being inhaled while outdoors on a patio or deck.

Yes. Sealing increases a system’s effectiveness and can save you money on operating costs over time. It is important because it increases the amount of suction we can achieve under the house. It also allows us to use a smaller fan with a lower operating cost and prevents conditioned air from leaving the home.

The pipe must exhaust one foot above the roof, at least 10 feet above the ground, and 4 feet above any window within 10 feet, according to code. This prevents high radon concentrations from re-entering a building or being inhaled while outdoors on a patio or deck.

No. The goal is for radon-laden air to move up and away from your home. Rain caps are a magnet for ice buildup and can allow radon to re-enter your home through nearby windows. The small amount of rain that does enter the system will flow into the soil since the pipe is pitched to allow condensation to drain. We do install a critter guard to keep small animals and birds from entering the system.

Yes. Fire stop collars prevent a fire from spreading from the garage to the house. Unfortunately, we often see contractors skip this very important step. American Radon Mitigation takes your family’s safety seriously and never skips important measures such as this.

Yes. Backdrafting is the reverse flow of exhaust gases from fuel-fired appliances (such as water heaters and furnaces) that results in a buildup of carbon monoxide inside your home. American Radon Mitigation tests for backdraft and takes measures such as sealing air leaks to fix most backdraft issues. In some cases, additional makeup air is sometimes required.

Some fans are louder than others. We offer an optional noise suppressor, that reduces the noise by approximately 75 percent.

Yes. We install a self-regulating heat cable that adjusts according to how cold it is outside. As temperatures drop, the cable adjusts its heat output. This prevents the radon system from freezing and keeps your family safe from radon during the cold winter months when you need it most.

Yes, we offer a variety of accessories, including:

• Noise suppressors
• Self-regulating de-icing cable
• Condensate bypass
• Water alarms
• Digital radon monitors
• Low airflow alarms

Yes, American Radon Mitigation will leave your home as clean, if not cleaner, than the way we found it.

Yes. American Radon Mitigation takes the time to educate all homeowners on system operations and what to do if they encounter a problem.

American Radon Mitigation records the negative pressures from the test holes once the system is installed and leaves a copy with you. We provide you with a free post-mitigation test kit to verify radon levels have been reduced.

With diagnostic testing, we can design a system for you based on data, not guesswork. If a post-mitigation radon test reveals elevated levels, American Radon Mitigation will recommend additional sealing, suction points, and/or fan upgrades.
