Radon may not be the first thing homeowners think about, but it should be high on the list of things to monitor. The serious health risks linked to heavy radon exposure make it something all homeowners need to be concerned about, which is why knowing what causes radon levels to be high is important.

What Causes Radon Levels to be High?

There is no way of escaping radon gas in your home, but you can hire a radon mitigator to use advanced tools that will reduce its levels. It is a naturally occurring gas that comes from a combination of soil, rock, and water. The gas is a radioactive and odorless substance that is released when the rock begins to break down.

There are many factors that can increase the chances of this gas reaching high concentrations in a house. This article will explore a few possibilities.


The reason you should worry about cracks in your walls and floors is that these openings can let radon gas in. Cracks form for different reasons like weather conditions or pressure placed on your home’s structure. Sometimes, cracks just form over time or due to poor workmanship. You should stay aware and repair any cracks to reduce the chances of increased levels radon in your house.

Flooring Issues

It is easy to overlook issues with your flooring, especially things like gaps. These gaps do not normally cause much trouble, and most homeowners would rather place carpet or a rug over the gap and call it good. There is no doubt that this solution is cost-effective, but it might not be worth the risk. It has been established that long-term exposure to radon could lead to serious ailments like lung cancer. Make sure that these gaps are addressed as soon as possible to reduce the chances of radon levels rising inside your home.

Plumbing Issues

Another factor that could be putting your home in danger of increased radon levels is a plumbing problem. You do not want to see gaps around the pipes going into your home since any large gap could be an entryway for radon gas into your home. Check behind your toilet and under the sink for holes that have not been patched up to keep gases out of your house. You might also want to check your tub and any other fixture to make sure no holes are there.

Living Near a Well

An additional factor that may be putting your home in danger is living close to a well. Those who have a well on their property should ensure that all cracks or holes in the house are found and plumbing is inspected as soon as possible, though this is still a good idea even if you don’t live next to a well. The reason you should be concerned is the well exposes water to rock and soil, so the probability of radon being produced is high. A thorough home inspection should help uncover any issues.

Now that you know what causes radon levels to be high, you should have your home inspected for these issues and have the professional home inspector conduct a radon test. You can address these issues and reduce the risk of being affected by radon.
