Radon is a silent, invisible threat lurking in many homes. Understanding the cost and types of radon mitigation systems is crucial for homeowners who want to ensure their living environments are safe and healthy.

Radon Mitigation Cost

The cost for installing a radon mitigation system can vary depending on several factors. Based on our research, here is a breakdown of the costs.

Average Cost of Radon Mitigation

Cost BreakdownAmount
National Average Cost$1,600
Minimum Cost$500
Maximum Cost$8,000
Average Range$1,200 to $2,000

These figures give us a ballpark idea of the expenses involved. Let’s delve into the specifics of various system types.

Radon Mitigation Cost by System Type

Different mitigation systems come with varying costs. Here’s a comparison of the main types:

Radon Mitigation System Cost Comparison

System TypeAverage Cost Installed
Active Soil Depressurization System$1,200 – $2,000
Other Foundation-Based System$900 – $8,000
Wall-Based System$500 – $3,000
Ventilation System$1,300 – $2,500
Water Mitigation System$1,200 – $5,000

Each system type serves different needs and its cost varies accordingly. Detailed below are some of the key types.

Active Soil Depressurization System

This is one of the most common and effective methods for radon mitigation. It involves creating a vacuum under the home to siphon radon gas away from the foundation.

Other Foundation-Based Systems

Various other systems can be installed based on the foundation type of the house. Costs can vary significantly depending on the complexity and size of the foundation.

Wall-Based Systems

Wall-based systems are another popular option. Here’s a closer look at the costs associated with typical wall-based systems:

Wall-Based Radon Mitigation System Cost Comparison

Wall-Based System TypeAverage Cost Installed
Block-Wall Depressurization (BWD)$1,800 – $3,000
Above-Slab Air Pressure Differential Barrier (ASAPDB)$500 – $1,200

These systems are effective for homes with specific construction types and are generally easier to install.

Ventilation Systems

Ventilation systems work by increasing the number of air changes per hour within a home, thereby reducing radon concentration.

Water Mitigation Systems

These systems are essential where radon is present in water sources. Costs vary depending on the complexity and the water source.

Additional Radon Mitigation Cost Factors

The overall cost of radon mitigation can be influenced by additional factors such as:

  • House Size and Layout: Larger homes may require more extensive systems.
  • Foundation Type: Different foundations (e.g., slab, crawl space, basement) require different approaches.
  • Local Labor Costs: Rates for professional labor can vary by region.
  • Pre-Mitigation Testing: Some homes require extensive testing to determine the best mitigation strategy.

Radon Levels by Location

Radon levels can vary widely by geographical location. Implementing a mitigation system in areas with high radon levels is crucial for safety. Refer to local radon maps and guidelines to gauge the radon levels in your area.

Radon Mitigation FAQs

What Is Radon, And Why Is It Dangerous?

Radon is a radioactive gas that naturally occurs from the decay of uranium in soil and rocks. It is dangerous because it can accumulate in homes and is a leading cause of lung cancer.

Is A Radon Mitigation System Worth It?

Yes, a radon mitigation system is worth it. It reduces radon levels, ensuring the health and safety of the occupants. Given the potential health risks, the investment is justified.

How Does A Radon Mitigation System Work?

A radon mitigation system works by reducing radon levels inside the home. This is achieved through techniques such as soil suction, sealing, and increasing ventilation.

How Long Does A Radon Mitigation System Last?

A radon mitigation system can last for decades with proper maintenance. It is advisable to perform regular checks and maintenance to ensure it remains effective.

Where Is The Best Place To Put A Radon Mitigation System?

The best place depends on the specific system type and house layout. However, most systems are installed in the basement or lowest level of the home.

Who Pays for Radon Mitigation, The Home Buyer Or Seller?

Responsibilities can vary based on agreements made during the home sale process. It is common for buyers to request the seller to cover mitigation costs as part of the negotiations.

Is Radon Mitigation Covered By Homeowners Insurance?

Typically, radon mitigation is not covered by homeowners insurance. However, it’s always best to check with your insurance provider to confirm.

Getting Estimates From Radon Mitigation Companies Near You

Choosing a reputable contractor is crucial for effective radon mitigation. Here are some questions to ask potential contractors:
