How Much Does a Radon Mitigation System Cost?

How much does a radon remediation system cost? The simple answer… it depends. It can be as little as $800. It can go up to $3,000. If you are unlucky (or lucky enough to have a very large house), it can be even more. The actual cost of radon protection depends on many variables, including the construction and size of your home and the type of system used. If you are concerned about radon, it is worth as much as your concern.

What is radon?

Radon is a type of naturally occurring radioactive gas. It is released from the soil when the natural uranium in the soil and water decays. As Family Handyman notes, radon is present in almost all soil, and the air we breathe every day has very low radon concentrations. So what exactly is the problem? Surely a natural substance can’t be that harmful? Wrong. Radon doesn’t often make the headlines. But that doesn’t mean there’s nothing to worry about. If you thought you had eliminated your risk of cancer by putting out your last cigarette, you’re in for a nasty surprise. According to the Environmental Protection Agency, radon is one of the leading causes of lung cancer in the country. Low and irregular exposure may not be a problem. The problem occurs when it enters your home and gets stuck. There is an increased risk of reaction to repeated exposure.

How does radon get into homes?

Radon is a gas. If there’s one thing all gases are good at, it’s getting into places they don’t belong. Radon can seep through concrete and get into all the tiny cracks in walls and floors. If there is a crack, crevice or hole, radon will find it and use it as an entry point.

How do you know if you have radon.

One of the biggest problems with radon? It’s almost undetectable. The smell is colourless, tasteless and invisible to the naked eye. The only proven way to know if you have a radon problem is a radon test. There are several ways to proceed: …..

Short-term tests

Short-term tests are available at hardware and home furnishings stores. They measure radon levels for 2 to 7 days. Once you have collected the data, you should send the information to the laboratory to review the results and determine if further testing is needed.

Long-term tests

Long-term radar tests are an improvement over short-term tests. They collect data from 90 days to a year. Since radon levels can vary greatly based on barometric pressure, soil moisture, snowfall and other variables, they can provide an accurate indication of the annual radon levels in your home.

Continuous testing

Continuous radon tests monitor both short-term and long-term radon levels and provide an overall average of annual radon levels.

Benefits of the Radon Absorption System

When tests show radon levels above 4 pCi/L, it’s time to take action and install a radon reduction system. First, ask your state’s EPA office for a list of certified, licensed or registered providers in your area. It’s not absolutely necessary, but it’s the safest way to avoid engaging someone who isn’t qualified to handle a dangerous gas like radon.

According to, there are four different radon mitigation systems that are commonly used. Regardless of the system, the objectives are the same:

  • to divert any radon gas present in the soil from the house.
  • to prevent reintegration by releasing radon from the walls.
  • To release radon gas from rooms and prevent it from reappearing.
  • For radon filtration in the water system
  • Once your system is installed, you can expect your home to be radon-free within about three days.

How much does a radon remediation system cost?

Now we come to the important question. How much does a radon remediation system cost? Because there are several variables to consider, costs can vary. As a guideline, you can expect to spend between $800 and $3,000. The variables that affect the determination of the total amount you can pay are the following:


If you hire an experienced contractor, expect to pay extra. The less skilled the workforce, the less you can expect to pay. However, think twice before taking cost-saving measures. Radon treatment is a specialized job. If you do not want someone who does not have the experience or qualifications to drill holes in the foundation of your home, it is best to look for the most qualified person you can find.


According to Home Advisor, the type of system you use has a significant impact on your overall cost. The two most common types of pressure relief systems are pressure relief and pressure relief. Basement waterproofing can also be considered, but since this method is 50% less effective than the other two, it is generally not recommended on its own. There are two types of decompression systems: active venting, where a fan creates a vacuum under the foundation of the house, and passive decompression, where noxious gases are vented through a pipe.

In general, you can expect the following costs, depending on the method you choose

  • Active pressure relief or bottom plate exhaust; $700 – $3,000
  • Passive suction : $500 – $2500
  • Lower pressure level : $500 – $1000
  • Seal it: $400 – $1500

Size and construction of house

One of the most important factors determining the cost of radon mitigation systems is the size and design of your home. As writes, houses that only have a basement are usually less expensive than those with an additional crawl space. It is more expensive to install exhaust air purification systems in larger homes over 4,000 square feet that require more than one intake point. If your basement is larger than 2,000 square feet, you will have to pay extra for additional entrances and waterproofing.

Current operating charges

The initial cost is one thing, but don’t forget to include the ongoing cost of a radon remediation system in your calculations. Depending on the system you use, you will pay between $30 and $300 per year for electricity.
