Different Ways on How to Remove Radon from Your Home

Last Updated on March 21, 2025 by Kravelv Spiegel

Discovering how to remove radon from your home is crucial, as this hazardous, radioactive gas can infiltrate from the ground, posing serious health risks such as lung cancer if ignored. This guide will lead you through vital steps to detect and eradicate radon, securing a safer living space. Explore the significance of radon testing and effective mitigation techniques to safeguard your household from this invisible threat, ensuring healthy indoor air quality.

What is Radon?

Radon is a radioactive gas that is colorless, odorless, and tasteless, making it difficult to detect without proper testing. It is produced from the natural decay of uranium found in soil, rock, and water, and it can enter homes through cracks and gaps in the foundation. Long-term exposure to high levels of radon increases the risk of lung cancer, making it essential to test and mitigate radon levels in residential areas to ensure a safe living environment.

Modern research has shown that 40% of the total radiation dose form by inhalation of natural radioactive gas Rn. Exposure to radon in higher concentrations and over a long period, especially in areas with uranium mineral deposits, may increase the chance of developing cancer lungs.

Why Is Radon Dangerous?

Radon is a natural gas that comes from rocks and soil. It can get into your home through small cracks in your foundation, gaps around pipes, and even well water. The biggest risk of radon is lung cancer. In fact, the EPA says radon is the second leading cause of lung cancer, responsible for about 21,000 deaths each year in the U.S. The risk is even higher if you smoke.

Factors affecting indoor radon concentration

Radon enters the indoor space from these sources:

• by diffusion from the soil,
• diffusion from building materials,
• by diffusion from the water used in your house,
• from the atmosphere through vents,
• Through cracks in floors or upstairs at the joints of structures, cavities around pipes and cables, small hollow pores in walls, and through the sewer.

Significant factors are the quality of construction, type of construction, ventilation, and seasonal climate change.

Because of the harmful effects of radon, an important task is – protecting and removing radon gas. In today’s conditions, many human activities lead to increased radiation of radon gas and its side effects.

Preventive protection procedures are procedures to reduce the concentration to an acceptable level, and can be:

• radon collection and drainage system,
• improved ventilation under the floor,
• formation of overpressure in the building,
• closing openings and cracks,
• Improved ventilation in the building.

6 Steps on How to remove radon from your home

Step 1: Testing for Radon

Testing for the presence of radon in your house is the first thing you should do when attempting to get rid of it. You may get radon testing kits at your neighborhood hardware shop or on the internet. The test requires you to take samples of the air in your house using the provided kit over the course of a few days, after which you will send the kit to a lab for examination. The laboratory will provide you with a report detailing your home’s radon level upon completion of the test.

Step 2: Hiring a Radon Mitigation Professional

If the results of the test reveal that your house has high levels of radon, the next step is to call a professional radon mitigation contractor. You can mitigate radon in a number of ways. These specialists have the training and knowledge necessary to evaluate your property and figure out the strategy that will be most effective in getting rid of the radon.

Step 3: Radon Mitigation System Design

The radon mitigation contractor will create a customized radon mitigation system for your dwelling as part of their service. In most cases, the system will require the installation of a vent pipe and fan in order to remove the radon from underneath your house and discharge it into the air outside. In order to stop radon from getting inside the house, the mitigation system could also comprise caulking any fractures in the foundation or the walls.

Step 4: Radon Mitigation System Installation

Following the completion of the radon mitigation system’s design phase, the contractor will carry out the system’s installation. Depending on the degree of difficulty presented by the system, the installation procedure might take anywhere from one to two days to complete.

Step 5: Post-Mitigation Testing

After installing the radon abatement system, it’s crucial to conduct additional testing to ensure it’s effectively reducing radon levels. Keep the test kit at home for a few days before sending it to a lab for analysis. After installing the system, the laboratory will give you a report containing information about the amount of radon present in your house.

Step 6: Radon Mitigation System Maintenance

Regular maintenance of your radon mitigation system is crucial for its efficient operation. Follow instructions from the contractor, which may include changing the filter, checking the fan, and monitoring the system’s performance.

DIY Ways of Removing radon gas from Houses:

If you want to star removing radon gas in your own, you need to take the following procedures:

• making a plate as a membrane for a part with reduced pressure (the purpose of this system is to form a vacuum area under the foundation, where radon collects and drains through pipes outside to a safe place).
• use of mechanical barriers to the entry of gases (plastic foils and sealing foundations and cracks stop the entry of radon).
• Degradation of the air distribution system so that polluted air is not used.

Drainage of polluted gases outside the building is done through pipes. In most family houses, one drain pipe is sufficient. If the floor is permeable, more drain pipes are required. There are active and passive under pressure systems. If you need to know more about this, please see this link.

You need to have:

• Gas-permeable layer (layer usually 10 cm thick of clean, coarse gravel)
• Plastic foil (above the gas-permeable layer to prevent gas from entering the building)
• Ventilation pipe
• Sealing and closing cracks (all openings on the concrete bottom are closed to prevent gas from entering the building)

Increased air circulation under the floors, when the building has free space below ground, leads to dilution of radon.

How to Lower Radon Levels

If your home has high radon levels, don’t panic! There are ways to fix it. Here are some of the best methods:

1. Install a Radon Vent System

This is the most effective way to remove radon. A pipe and fan system pulls radon from under your house and vents it outside. It’s commonly used for homes with basements or concrete slab foundations.

2. Seal Cracks and Gaps

Radon gets in through small openings in your floors, walls, and around pipes. Sealing these cracks with caulk or special sealants can help reduce radon levels. However, this method works best when used with other solutions.

3. Improve Airflow in Your Home

Better ventilation can help lower radon levels by letting fresh air in and pushing radon out. You can:

• Open windows and use fans to circulate air.
• Install a heat recovery ventilator (HRV) to bring in fresh air while keeping energy costs low.

4. Use a Radon Sump System

If radon levels are really high, a sump system might be needed. This involves digging a pit under your home and installing a pump to remove radon gas and moisture from the soil.

How Much Does It Cost to Fix Radon?

The cost of radon removal depends on the method you choose and your home’s structure. Here’s a rough estimate:

• DIY radon test kit: $10 – $30
• Professional radon testing: $100 – $300
• Radon removal system: $800 – $2,500

It may seem expensive, but reducing radon levels protects your health and adds value to your home.

What to Do After Fixing Radon

Once you’ve installed a radon removal system, test your home again to make sure it worked. The EPA suggests retesting every two years, or sooner if you do major renovations.

Check Local Radon Rules and Help Programs

Some states offer free or low-cost radon test kits or financial help for radon fixes. Check with your local health department or EPA office to see what’s available in your area.
