Protect Your Family’s Health: Why Radon Mitigation is Critical During Pierce County Basement Renovations

When planning a basement renovation in Pierce County, Washington, many homeowners focus on flooring, lighting, and layout—but there’s a hidden danger that could be lurking beneath your foundation. Radon is a naturally occurring radioactive gas that comes from the radioactive decay of elements naturally found in rocks and soils. You can’t see it, smell it, or taste it. It could be in your home damaging your family’s health. This invisible threat makes radon mitigation an essential safety upgrade that should never be overlooked during basement remodeling projects.

Understanding the Radon Risk in Pierce County

In Washington State, areas like King County, Pierce County, and Snohomish County are not immune to radon presence. It is typical to find higher radon concentrations in below ground areas, such as basements, and less the further you go up in the home. However, for a basement that includes a TV room, game room, bedroom, office, or craft room where your family spends hours each day testing is important. This makes basement renovations the perfect time to address potential radon issues before they become a serious health concern.

According to the Environmental Protection Agency (EPA), radon exposure is the leading cause of lung cancer among nonsmokers. It’s responsible for about 21,000 U.S. deaths each year. When you’re investing in transforming your basement into a livable space, protecting your family from this silent killer should be your top priority.

Why Renovation is the Perfect Time for Radon Mitigation

Like most home features, a radon mitigation system can be installed much easier and at much less cost during construction. Radon-resistant new construction techniques can be used while a new house is being built to help ensure radon is kept outside of your home. The same principle applies to major renovations—addressing radon during your basement remodel is significantly more cost-effective than retrofitting later.

During renovation, contractors already have access to your foundation, floors, and walls, making it the ideal time to implement radon mitigation measures. These options can help reduce radon levels in your home by making it harder for radon to get in: Caulk and seal cracks in your basement, foundation, and subfloor. Install a gas-tight vapor barrier in your crawl space.

Essential Radon Safety Upgrades for Your Basement Renovation

Washington State building codes require specific radon control methods in designated high-risk areas. The following construction techniques are intended to resist radon entry and prepare the building for post-construction radon mitigation, if necessary. These techniques are required in high radon potential counties designated in Table AF101(1). A layer of gas-permeable material shall be placed under all concrete slabs and other floor systems that directly contact the ground and are within the walls of the living spaces of the building, to facilitate future installation of a subslab depressurization system, if needed.

Key mitigation upgrades to consider during your basement renovation include:

• Sub-slab Depressurization Systems: Radon mitigation is the process of lowering radon concentrations in homes, primarily done through sub-slab depressurization (SSD). SSD works by creating negative pressure beneath the foundation to prevent soil gases from infiltrating living areas. A typical radon mitigation system comprises a suction pit under the home, a network of pipes, and a radon fan to exhaust the gas outside.
• Proper Sealing: Caulk and seal cracks in your basement, foundation, and subfloor.
• Ventilation Systems: The most common method involves a vent pipe system and a fan that pulls radon from beneath the house and releases it safely into the air outside.
• Vapor Barriers: Inspect and fix, or install, a good crawl space vapor barrier. Ensure a vapor barrier is in good condition with any seams, holes, or tears well taped.

Radon testing is the only way to determine if the gas is present in your home. According to the EPA, if the radon level in your home is 4 picocuries per liter (pCi/L) or higher, you should consider installing a radon mitigation system. Professional testing both before and after renovation ensures your mitigation efforts are effective.

Cost Considerations and Long-term Benefits

In general, costs can range from $5,800 to $7,000 for a 2000sf building in Washington State. However, Building radon resistance into a new house is far less costly than radon mitigation after construction. The passive system outlined below is 50%–70% of the cost of a retrofitted radon mitigation system, which is about $1,200 to install and can have significant operating costs.

Beyond the immediate health benefits, understanding how radon affects your living environment can help protect the health of your family. If you discover elevated radon levels in your home, installing a mitigation system not only enhances safety but also adds value to your property.

Taking Action During Your Renovation

When work to reduce radon in your home is done, it is important to retest to see if efforts have reduced radon to a safe level. If your retest shows you still need to lower your radon levels, consider hiring a Certified Radon Professional.

Don’t let your basement renovation be just about aesthetics—make it about safety too. By incorporating radon mitigation measures during your Pierce County basement remodeling project, you’re not just creating a beautiful space; you’re creating a healthy environment where your family can thrive for years to come. The investment in radon safety upgrades today will pay dividends in peace of mind and protection for your loved ones tomorrow.
