How to Maintain Your Radon Mitigation System for Long-Term Safety

3/19/2026

0 Comments

 
Maintain Your Radon Mitigation System
Installing a radon mitigation system is one of the most important steps you can take to protect your home and family. But like any home system, it requires occasional monitoring and maintenance to ensure it continues working properly for years to come.

At Radon Mitigation Spokane, we often tell homeowners that installation is just the first step — long-term safety comes from proper upkeep.

Here’s what you need to know.

Why Maintenance Matters

A properly installed radon mitigation system can reduce radon levels by up to 99%. However, system components like fans, seals, and vent pipes can wear down over time. If the system stops functioning correctly, radon levels can rise again without you realizing it.
​

Since radon is invisible and odorless, the only way to stay protected is to monitor your system regularly.

1. Check the Manometer Regularly

Check the Manometer Regularly
Most radon mitigation systems include a U-tube manometer, a small gauge mounted on the vent pipe. This device shows whether the system fan is creating proper suction.
  • The liquid levels in the tube should be uneven.
  • If both sides are equal, your fan may not be working.
  • If you’re unsure what the reading means, contact a professional.

This simple visual check only takes a few seconds and can prevent long-term exposure.

2. Listen for the Fan

 Radon Mitigation System fan
Radon mitigation systems run continuously. While the fan is usually quiet, you should occasionally:
  • Listen for unusual noises
  • Watch for vibration changes
  • Check for warning indicators if installed

Most radon fans last about 5–10 years. If the fan fails, radon levels can increase quickly, so prompt replacement is important.

3. Inspect the Vent Pipe

Inspect the Vent Pipe
The PVC vent pipe carries radon gas safely above your roofline. Make sure:
  • It remains securely attached
  • No cracks or damage are visible
  • The exhaust point is unobstructed

Spokane’s seasonal weather changes can sometimes impact exterior components, so a yearly visual inspection is wise.

4. Seal Foundation Cracks

Even with a mitigation system installed, sealing visible cracks in your foundation improves system efficiency. Over time, new settling cracks may appear.
​

Use appropriate sealants or consult a professional if larger gaps develop.

5. Retest Your Home Every Two Years

Radon Testing
Even if your system appears to be working properly, experts recommend radon retesting at least every two years. You should also retest:
  • After major renovations
  • After replacing a fan
  • If you notice structural changes
  • Before selling your home

Testing confirms your system continues to maintain safe radon levels.

6. Schedule Professional Inspections

While many checks are simple, a professional inspection ensures:
  • The fan is operating within proper pressure range
  • Seals remain airtight
  • The system meets current safety standards
  • No hidden issues are developing
    ​
For homeowners in Spokane and surrounding areas, working with a local radon specialist ensures your system is optimized for regional soil and climate conditions.

Guide to Radon Reduction: Protecting Your Home and Health

11/3/2023

Radon gas, often lurking silently in our homes, can pose significant health risks if not addressed promptly. In this comprehensive guide, we will explore the ins and outs of radon gas, its health implications, how to measure its levels, and most importantly, the steps to reduce radon exposure in your home.

Understanding Radon

What Is Radon Gas?

To tackle a journey toward a safer home and healthier life, it's essential to grasp the fundamentals. Radon is an odorless, colorless, and tasteless radioactive gas originating from the natural decay of uranium in the soil and rocks beneath your home. Radon seeps through the ground and can infiltrate your home through cracks in the foundation, walls, floors, and even well water.

The Health Risks Associated with Radon Exposure

Now that we've identified radon let's move on to the more critical issue of health dangers. Continuous radon exposure has been connected with lung cancer, making it the second leading cause after smoking. Radon decays into radioactive particles that can be inhaled and trapped in the lungs, releasing energy and damaging lung tissue. This can eventually lead to the development of cancer.
Smokers are at a higher risk of developing lung cancer due to radon exposure, but nonsmokers are not immune. As a result, all homes must assess and mitigate radon levels to protect their family's health.

Measuring Radon Levels

To protect your family's health from radon-related problems, you must first evaluate the radon levels in your home. Radon testing might help you with this. You have two primary options: short-term and long-term testing. Short-term testing usually lasts two to seven days and indicates radon levels. Long-term trials, however, are conducted over 90 days and provide a more realistic picture of your home's radon exposure.
​

Radon testing kits can be purchased at local hardware stores and online sellers. These kits are simple to use and have detailed instructions for accurate outcomes. It's crucial to place the test kits in the lowest livable area of your home, such as the basement or ground floor, as these areas often have higher radon concentrations.

Understanding Radon Reduction Systems

Don't be alarmed if your radon test results show high levels. You may take simple steps to lower your risk of radon exposure. Radon reduction systems, also known as radon mitigation systems, are designed to reduce radon levels in your house to a safe level. Sub-slab depressurization, sub-membrane depressurization, and active soil depressurization are the most common radon reduction systems.

Hiring a Radon Mitigation Professional in Spokane, WA

While radon reduction systems can be installed by homeowners with the right skills and knowledge, hiring a professional radon mitigation expert is highly recommended, especially in areas with known radon issues like Spokane, Washington. These professionals have the expertise and equipment to deliver successful radon reduction according to your home's needs.
​

Their expertise can make all the difference in ensuring your home is safe from radon exposure.

Radon Reduction: A Step-by-Step Process

Here's a step-by-step guide on how a radon reduction system works:
​
  1. Installation: The radon reduction system is installed once the assessment is complete. This usually involves creating a depressurization zone beneath your home, allowing radon to be vented safely outside.

  1. Post-Installation Testing: After installation, post-testing is conducted to ensure the system effectively reduces radon levels to safe levels. This final step is essential in securing the system's effectiveness.
​
  1. Initial Assessment: The process begins with thoroughly evaluating your home's structure and radon levels. The expert will pinpoint the most effective system for the exact situation.

Choosing the Right Radon Reduction System

When selecting a radon reduction system, consider the following factors:
​
  • Type of System: Choose the system that suits your home's design and radon levels.

  • Experience: Make sure that the professional or company you hire has experience in radon mitigation and comes highly recommended.

  • Licensing and Certification: Confirm that the expert or company is licensed and certified to carry out radon mitigation.
​
Cost: Request multiple quotes to compare pricing, but remember that the cheapest option may only sometimes be the most effective.

Maintaining Your Radon Reduction System

Once your radon reduction system is in place, it's important to keep it well-maintained. Regular check-ups and maintenance are essential to ensure the system continues functioning effectively. It's advisable to have your system inspected at least every two years or more frequently if you notice any changes in radon levels.

Conclusion

Radon gas is a hidden threat that could be creeping into your home, posing severe health risks to you and your family. The first step in preserving your home and health is understanding what radon is, its health concerns, and how to measure its levels.

If you find high radon levels, it's important to take action. Hiring a professional radon mitigation expert in regions such as Spokane, WA, is highly recommended for the best radon reduction. A properly installed radon reduction system can make your home safer, especially by reducing the risk of lung cancer caused by radon exposure.

Remember that your family's health and safety should always come first. Take the essential measures to reduce radon in your house and enjoy peace of mind, knowing you've taken action to protect your home and health from this silent but deadly threat.
