Radon Remediation
Radon is a naturally occurring radioactive gas that can accumulate inside homes and buildings without any visible warning signs. Because it is odorless, tasteless, and invisible, the only way to detect it is through proper testing—and the only way to reduce elevated levels is through a professionally designed radon remediation solution.
At Aspen Radon, we specialize in delivering safe, effective, and long-lasting radon reduction systems tailored to residential and commercial properties. Our team of experienced radon remediation contractors focuses on protecting families, homeowners, and businesses by reducing radon exposure to safe levels in accordance with EPA guidelines.
If your property has tested high for radon, or you want peace of mind about indoor air quality, our radon remediation services provide a proven and reliable solution.
What Is Radon Remediation?
Radon remediation is the process of reducing radon gas concentrations inside a building to safe levels. This is typically achieved by installing a specialized ventilation system designed to prevent radon from entering the indoor air or to safely redirect it outside before it accumulates.
The most common and effective method used today is active soil depressurization (ASD), which involves creating a suction point beneath the foundation and using a fan system to draw radon gas from the soil and vent it safely above the roofline.
A properly installed radon remediation system can reduce radon levels by up to 99%, making it one of the most effective home safety improvements available.
Why Radon Remediation Is Important
Long-term radon exposure is the second leading cause of lung cancer after smoking. According to health studies, even moderate levels of radon exposure can pose significant health risks over time.
Radon can enter homes through:
Cracks in concrete foundations
Gaps around pipes and utility lines
Crawl spaces and sump pits
Construction joints
Soil beneath basements and slabs
Because radon levels vary from home to home—even within the same neighborhood—professional remediation is the only reliable way to ensure your indoor air is safe.
Ignoring elevated radon levels can lead to prolonged exposure, which is why timely mitigation is essential.
Our Radon Remediation Process
At Aspen Radon, we follow a structured and proven approach to ensure every radon remediation system is effective, efficient, and built to last.
1. Initial Radon Assessment
We begin by reviewing your radon test results or conducting a new diagnostic evaluation if needed. This helps us understand the severity of the issue and identify the best radon mitigation strategy.
2. Property Radon Inspection
Our radon remediation contractors inspect your foundation type, basement layout, and airflow patterns. Every home is different, so we design a custom solution rather than using a one-size-fits-all approach.
3. System Design
We design a radon remediation system based on your home’s structure. This may include one or multiple suction points, strategic piping routes, and the appropriate fan capacity to ensure optimal performance.
4. Professional Installation
Our certified technicians install the system with minimal disruption to your home. We ensure all components are properly sealed, routed, and vented above the roofline for maximum safety and efficiency.
5. Post-Installation Testing
After installation, we perform follow-up radon testing to confirm that radon levels have been significantly reduced and meet EPA-recommended safety standards.
Types of Radon Remediation Systems
Different homes require different solutions depending on foundation type and radon levels. The most common systems we install include:
Sub-Slab Depressurization System
This is the most widely used radon remediation system for homes with basements or slab foundations. It involves drawing radon gas from beneath the concrete slab before it enters the home.
Sub-Membrane Depressurization System
Used primarily in crawl spaces, this system installs a protective barrier (membrane) that traps radon gas and channels it into a vent pipe system.
Sump Pit Depressurization
For homes with sump pump systems, we can convert the sump pit into a suction point to help remove radon gas efficiently.
Passive to Active System Upgrades
Some homes are built with passive radon systems that can be upgraded with a fan to significantly improve performance.
Each system is designed to meet the specific needs of your home while ensuring long-term radon reduction.

How a Radon Remediation System Works
A radon remediation system works by changing the air pressure beneath your home’s foundation. When the pressure is reduced, radon gas is prevented from entering indoor spaces and is instead safely vented outside.
A typical system includes:
A suction point installed in the foundation
PVC piping that runs through the home or exterior
A continuously operating fan
A vent discharge above the roofline
Once installed, the system runs continuously and quietly, requiring minimal maintenance while providing ongoing protection.
When Should You Install Radon Remediation?
You should consider radon remediation if:
Your home tested at or above 4.0 pCi/L
You are buying or selling a property with elevated radon levels
You live in a high-risk radon zone
You want to improve indoor air quality and safety
You have never tested your home for radon before
Even if radon levels are slightly below the EPA action level, many homeowners choose radon mitigation for added peace of mind.
Maintenance of Radon Remediation Systems
Radon systems are low-maintenance, but periodic checks ensure continued performance. We recommend:
Checking the system fan indicator regularly
Testing radon levels every 1–2 years
Inspecting vent pipes for damage or blockages
Ensuring the fan is operating continuously
Aspen Radon also provides support and maintenance services if adjustments or repairs are needed.

Frequently Asked Questions About Radon Remediation
What is radon remediation?
Radon remediation is the process of reducing radon gas levels inside a home or building using a specialized ventilation system designed to safely redirect radon from beneath the structure to the outdoors. Since radon is a naturally occurring radioactive gas that cannot be seen, smelled, or tasted, remediation becomes necessary when testing shows elevated levels that could pose long-term health risks. The system works by creating a controlled pathway that prevents radon from entering indoor living spaces, typically by drawing the gas from beneath the foundation and venting it above the roofline. This significantly improves indoor air quality and helps ensure the home meets recommended safety standards.
How effective is a radon remediation system?
A properly designed and professionally installed radon remediation system is highly effective, often reducing indoor radon levels by up to 99%. Its performance depends on factors such as the home’s foundation type, soil conditions, and the quality of installation, but when set up correctly, it provides consistent and long-term protection. Many homes that initially test above the EPA action level of 4.0 pCi/L can be brought down to much safer levels after mitigation. Because the system runs continuously, it maintains reduced radon levels over time, offering reliable protection for homeowners and occupants.
How long does installation take?
Most radon remediation system installations can be completed within a single day, especially for standard residential properties. The timeline usually ranges from a few hours to a full day, depending on the size of the home, foundation type, and complexity of the system design. Simpler setups in basements or slab-on-grade homes are typically faster, while properties requiring multiple suction points or crawl space modifications may take longer. Despite the installation work, disruption is usually minimal, and the system begins working immediately once activated.
Do I need professional radon remediation contractors?
Yes, working with professional radon remediation contractors is essential because every property requires a customized approach based on its structure and radon levels. Contractors assess key factors such as foundation type, soil conditions, and airflow patterns to design an effective mitigation system. Without professional installation, there is a risk of improper sealing, incorrect system sizing, or poor placement, all of which can reduce effectiveness and leave occupants exposed to unsafe radon levels. Certified contractors ensure the system is installed correctly, operates efficiently, and complies with industry safety standards.
How much does radon remediation cost?
The cost of radon remediation varies depending on the size of the home, the type of foundation, and the complexity of the system required, but it is generally considered a one-time investment in long-term health and safety. Factors such as crawl space sealing, number of suction points, and piping layout can influence pricing. While there is an upfront cost, ongoing expenses are minimal, usually limited to the small electricity usage of the system fan. Many homeowners view it as a valuable investment not only for health protection but also for added property value and peace of mind.
