How Much Does Radon Mitigation Cost in Georgia?

One of the first questions homeowners ask after receiving a high radon test result is: "How much is this going to cost me?" It's a fair question. You want to protect your family, but you also need to budget for the work.

The good news is that radon mitigation is more affordable than most people expect — and far less expensive than the health consequences of long-term radon exposure.

In Georgia, the typical cost for a radon mitigation system installation ranges from $800 to $2,500, with most homeowners paying between $1,000 and $1,500 for a standard single-family home.

This price range covers the most common mitigation method — sub-slab depressurization (SSD) — which is effective for the vast majority of Georgia homes. The system includes:

• A PVC pipe routed through the foundation slab or crawl space
• An in-line fan that creates negative pressure beneath the foundation
• Exterior venting that safely exhausts radon above the roofline
• All labor, materials, and sealing of major entry points
• A post-mitigation radon test to verify the system is working

Several variables influence where your project falls within the price range:

The type of foundation your home has is the single biggest cost driver:

• Slab-on-grade: Most straightforward installation. One or two suction points are typically sufficient. Cost: $800–$1,400.
• Basement: Similar to slab, but may require additional suction points depending on the basement's size and layout. Cost: $900–$1,600.
• Crawl space: Requires encapsulation of the crawl space with a vapor barrier before or alongside the mitigation system. This adds cost but is often necessary for effective results. Cost: $1,200–$2,500+.
• Mixed foundation: Homes with both a slab and a crawl space, or a partial basement, may need a more complex system. Cost: $1,500–$2,500.

Most homes require only one suction point — a single pipe penetrating the slab. However, larger homes, homes with multiple foundation sections, or homes with poor sub-slab communication (dense soil or gravel that doesn't allow air to move freely) may need two or more suction points. Each additional suction point adds $200–$400 to the total cost.

Radon mitigation fans vary in power and price. A standard residential fan costs $150–$300. Homes with very high radon levels or challenging soil conditions may require a higher-capacity fan, which can add $100–$200 to the cost.

Where the pipe exits the home affects labor time and materials. Interior routing (through the house and out the roof) is more discreet but takes longer to install. Exterior routing (along the outside of the house) is faster and less expensive. Your contractor will recommend the best option based on your home's layout.

A follow-up radon test after installation is essential to confirm the system is working. At Georgia Radon Pros, we include post-mitigation testing in every installation. Some contractors charge separately for this — make sure you ask before signing a contract.

Absolutely. Consider the context:

• The average radon mitigation system costs $1,000–$1,500 and lasts 10–20 years with minimal maintenance (an annual fan check and periodic re-testing).
• Lung cancer treatment costs tens of thousands of dollars and carries a 5-year survival rate of only about 25%.
• Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year.

A properly installed mitigation system can reduce indoor radon levels by 90% or more. For a family of four living in a home with elevated radon, that reduction represents a significant, measurable decrease in lifetime cancer risk.

You may have seen DIY radon mitigation kits online. We strongly advise against attempting to install a mitigation system yourself unless you have specific training in radon mitigation.

Here's why: An improperly installed system can actually make radon levels worse by creating pressure imbalances that draw more radon into the home. It can also create carbon monoxide backdrafting risks if the system interferes with your home's combustion appliances. NRPP and EPA guidelines require that mitigation systems be installed by certified professionals for a reason.

The best way to get an accurate cost estimate is to schedule a free in-home assessment with a certified radon mitigation contractor. During the assessment, the contractor will:

1. Review your radon test results
2. Inspect your foundation type and condition
3. Assess sub-slab communication (how freely air moves beneath your slab)
4. Evaluate pipe routing options
5. Recommend the appropriate system and provide a written estimate

At Georgia Radon Pros, we offer free estimates for all mitigation projects. Our NRPP-certified technicians will walk you through the entire process, explain your options, and provide a transparent, itemized quote with no hidden fees.

Not all radon contractors are equal. When evaluating contractors, look for:

• NRPP or NRSB certification: These are the nationally recognized credentials for radon professionals. Always verify certification before hiring.
• Written warranty: A reputable contractor will guarantee their work and offer a warranty on the system.
• Post-mitigation testing: Insist that post-installation testing is included in the price.
• Clear, itemized pricing: Avoid contractors who give vague estimates or refuse to put the scope of work in writing.
• Local experience: A contractor familiar with Georgia's geology and building stock will be better equipped to design an effective system for your home.

Georgia Radon Pros is NRPP-certified, fully insured, and has served homeowners across North Georgia and Upstate South Carolina for years. We stand behind every installation with a written warranty and include post-mitigation testing on every job.
