How Does a Radon Mitigation System Work: Explained By Experts

There are various radon mitigation systems available that cater to different needs and budgets. In general, these systems use either suction or pressurization methods to reduce radon levels. Active systems are more efficient than passive ones, employing fans to create negative or positive pressure to draw radon away from the house or prevent it from entering.

Key Takeaways

  • Radon mitigation systems help protect homes from the health risks associated with radon exposure.
  • Different types of systems exist, including active and passive options.
  • Proper installation, functioning, and maintenance are crucial for the effectiveness of a radon mitigation system.

Fundamentals of a Radon Mitigation System

A radon mitigation system is designed to reduce the concentration of radon gas in the indoor air of a building. These systems are generally classified into two primary categories: active and passive systems. 

The primary objective of an active radon mitigation system is to prevent radon gas from entering a building or to vent it once it is inside. One of the most widely used strategies for achieving this is through sub-slab depressurization, which involves creating a vacuum beneath the building’s foundation to prevent radon from seeping in through soil.

To implement this method, we first install a vent pipe system, which starts below the foundation and extends up through the building and out the roof. A radon fan is then connected to the vent pipe system to create suction and actively remove radon from the soil beneath the building. This fan is an essential component of the system, as it ensures that radon is effectively pulled out through the vent pipe and released safely into the outdoor air.

The effectiveness of a radon mitigation system relies on the proper sealing of any cracks or gaps in the building’s foundation. This helps to create a tight seal, preventing radon from infiltrating the indoor air. It also maximizes the efficiency of the soil suction, ensuring that the majority of radon gas is captured and vented outside.

A well-designed and properly installed radon mitigation system can be incredibly effective at reducing indoor radon levels, creating a safer environment for occupants. It is important to have the installation carried out by licensed professionals to ensure the highest level of safety and effectiveness.

Installation of Radon Mitigation System

Installing a radon mitigation system is an effective way to reduce radon gas levels in a home. We will go through the process of installing such a system, focusing on the key aspects mentioned.

Firstly, it’s essential to have a thorough inspection of the foundation, walls, and other entry points for radon gas. This helps in identifying areas that need to be addressed. Hiring a professional contractor with expertise in radon mitigation is recommended as they possess knowledge of various trades like plumbing, electrical, and roofing.

The primary method of installing a radon mitigation system is by sealing the foundation and walls of the home. This involves applying a layer of concrete to effectively cover any gaps and cracks that may be present. It’s important to tackle these issues, as they are common home repairs that can significantly impact the effectiveness of the radon reduction system.

Another crucial aspect of the installation process is putting down a plastic sheet over the soil and crawlspaces before sealing the foundation. This sheet acts as a barrier to prevent radon gas from seeping into the house and also helps to maintain moisture levels.

Next, we must focus on sealing cracks in the walls and around pipes or other openings. This can be accomplished using caulk or other suitable materials that prevent radon from entering the home.

Once the foundation and walls are properly sealed, it’s time to install the radon reduction system. The most common type of system employs an active suction method, which uses a fan to draw radon gas out of the house. Another option is a passive suction system, which relies on natural ventilation to reduce radon levels. The effectiveness of these systems depends on the initial concentration of radon gas in the home and the type of system chosen.

In conclusion, installing a radon mitigation system is an important step in reducing radon gas levels and providing a safer living environment for occupants. With proper sealing of foundations, walls, and other potential entry points, we can confidently and efficiently reduce radon levels in our homes.

Maintenance of Radon Mitigation System

This system consists of three main parts: a radon fan, electrical power supplied to the fan, and piping to vent radon gas out from the lowest level of the home to the highest point outside the house.

Maintaining a radon mitigation system is crucial to ensure its efficiency. Although these systems do not require annual maintenance appointments like other appliances, there are some general visual inspections and maintenance tips we can follow:

  1. Check the fan unit: Radon fans are engineered to run 24 hours a day, venting radon out of your home for years. Observe the fan unit for any unusual noises, vibrations, or signs of malfunction.
  2. Examine the piping system: Inspect the piping running from the fan to both the lowest level of the home and the highest point outside. Look for any leaks, cracks, or blockages that could compromise the effectiveness of the radon mitigation system.
  3. Monitor radon levels: After the initial installation of the radon mitigation system, it is essential to regularly monitor the radon levels in your home. This can be done using a radon test kit or by hiring a professional service. Monitoring will help identify any fluctuations in radon levels and indicate if the system needs any adjustments or repairs 

By following these simple maintenance tips and ensuring the proper functioning of our radon mitigation system, we can effectively reduce radon levels and maintain a safer living environment in our homes.

Frequently Asked Questions

What are the different types of radon mitigation systems?

There are several types of radon mitigation systems, and the choice depends on the specific needs of your home. The most common types are passive sub-slab depressurization (SSD) systems, active SSD systems, and crawl space depressurization systems. Passive SSD systems rely on the natural pressure differential between the outside air and the area beneath the sub-slab to vent radon, while active SSD systems use a fan to create a pressure difference and extract radon from the soil beneath your home. Crawl space depressurization systems work by reducing the air pressure in the crawl space relative to the living space, which prevents radon from entering your home.

How much does it cost to install a radon system in Colorado?

The cost of installing a radon mitigation system varies depending on the type of system and the complexity of the installation. On average, homeowners can expect to spend $800-$1,500 for a professional radon mitigation system installation, although this cost can go up to $2,500 or more for more complex situations. Get a quote for your home or business from a Denver radon mitigation expert.

Do radon systems run continuously?

Radon mitigation systems generally run continuously to maintain a constant pressure difference and prevent radon from entering your home. This continuous operation is essential for active SSD systems, as they use a fan to create and maintain a pressure differential under your home’s foundation. Passive SSD systems can run continuously in some cases, but their efficiency depends on the natural pressure differential between the outside air and the area beneath the sub-slab.
