How to Protect Your House From Radon Gas

With 1 in 15 homes in the US estimated to have elevated radon levels as per the Environmental Protection Agency (at least 4 pCi/L). It is important to know how to protect your house from this potentially harmful gas. After all, no one wants to put their family at risk.

So, how can you protect your home from this silent killer? Some effective methods include testing your home for radon using a radon test kit, sealing cracks and openings in your foundation, and installing a radon mitigation system for radon reduction.

Read on for a detailed guide on each of these methods.

How Does Radon Sneak Into Your House?

Radon is a naturally occurring gas that is produced when uranium breaks down in the soil. It's odorless, colorless, and tasteless, so you won't know it's there until you test for it.
This gas can enter your home through cracks and openings in the foundation or floor. Once it's inside, it can build up to dangerous levels. Seeping into the air you and your family breathe, radon increases the risk of lung cancer.

In fact, radon is the second leading cause of lung cancer in the US after smoking. According to the EPA, it's responsible for about 21,000 lung cancer deaths every year.

That's why it's so important to take action to protect your home from radon gas. By following the steps below, you can keep your family safe from this invisible threat.

Protecting Your House From Radon Gas: 5 Method

Test Your Home for Radon

The first step in protecting your home from radon is to test for its presence. While elevated levels can be found all across the US, they're more common in certain areas.

If you live in a high-risk area or your home has never been tested, it's important to get it done as soon as possible. You can test for radon yourself with a do-it-yourself kit, or you can hire a professional.

If you do it yourself, make sure to follow the instructions carefully and send the kit to a lab for analysis. These results will tell you how much radon is present in your home and whether you need to take action to reduce it.

While short-term radon tests are great for getting a quick idea of the radon levels in your home, they're not as accurate as long-term tests. For a more accurate reading, opt for a long-term test that will measure radon levels over the course of several months.

Seal Cracks and Openings in Your Foundation

Radon's sneaky nature means it can enter your home through the smallest of cracks and openings. To keep it out, it's important to seal these up.

Look for cracks in your foundation and walls, and pay special attention to any gaps around pipes or wires that enter your home. These are all potential entry points for radon gas. The most common type of foundation is concrete block, which is particularly susceptible to cracks.

To seal cracks and openings, you can use caulk, hydraulic cement, or expandable polyurethane foam. Whichever product you choose, make sure it's labeled as being able to block radon gas.

We recommend hiring a professional to do this job for you, as they'll know exactly where to look and how to properly seal any cracks or openings.

Install a Radon Mitigation System

Let's say you've tested your home for radon, and the levels are elevated. Or maybe you live in an area known for high radon levels. In either case, it's a good idea to install a radon mitigation system.

A radon mitigation system is designed to reduce the levels of radon gas in your home. It does this by creating a barrier between your home and the soil, which prevents radon from seeping in.

There are several different types of radon mitigation systems, with active and passive being the most common. Active systems use a fan to draw radon gas out of the soil and vent it away from your home. Passive systems don't use a fan but instead rely on natural air currents to do the job.

Installing a radon mitigation system is a big job, so we recommend hiring a professional. They'll be able to assess your home and recommend the best type of system for your needs.

Improve Ventilation in Your Home

Ventilation is another important method of reducing radon levels in your home. By increasing the amount of fresh air circulating, you can help to dilute and remove any radon gas that's present. This is especially effective when used in conjunction with a radon mitigation system.

There are several ways to improve ventilation in your home.

One is to open windows whenever possible, especially on lower levels where radon gas is more likely to be present. Another is to install an exhaust fan in the basement or other areas of your home that might be susceptible to radon buildup.

You can also install a heat recovery ventilator, which will help circulate fresh air throughout your home while maintaining energy efficiency.

Make Sure Your Home Is Well Insulated

You might not realize it, but the level of insulation in your home can have an impact on radon levels. That's because radon gas is heavier than air, so it tends to collect in poorly ventilated areas.

If your home isn't well insulated, radon gas can seep in through cracks and openings. Once inside, it can become trapped and build up to dangerous levels. This is why it's so important to make sure your home is properly insulated.

There are several different types of insulation, so you'll need to choose the right one for your needs. Fiberglass batts and rolls are common in many homes, but they won't do much to keep radon gas out. A better option is spray foam insulation, which can help to create a tight seal and prevent radon from seeping in.

The Bottom Line

Radon gas is nothing to mess around with. It's odorless, colorless, and tasteless, so you won't know it's there until it's too late. That's why it's so important to take steps to protect your home from this invisible threat.

The five methods we've outlined above are the best ways to reduce radon levels in your home. But remember, the only way to know for sure if you have a problem is to test your home for radon gas. If the levels are elevated, take action immediately to mitigate the risk.
