1. Do Not Panic
Getting a radon result above 4 pCi/L can feel alarming, especially if you have been reading about radon and lung cancer. But before you react, here is some important perspective.
Elevated radon is one of the most common findings in home inspections across Georgia, particularly in the northern counties. The EPA estimates that about 1 in 15 homes nationwide has radon above the action level. In some Georgia counties, the percentage is higher.
Unlike structural defects, foundation problems, or environmental contamination, radon is a straightforward, affordable fix. A professional mitigation system costs $1,200 to $2,500, installs in about a day, and reduces radon levels by 90% to 99%. Once installed, the problem is solved permanently.
A high radon reading should not kill a deal. It should inform a negotiation. You now have information that the seller probably did not have before, and that information gives you leverage.

2. Understand Your Results
Before you negotiate, make sure you understand what your test results actually mean.
The EPA action level is 4.0 pCi/L. If your test shows a result at or above this number, the EPA recommends mitigation. Results between 2.0 and 3.9 pCi/L are below the action level but the EPA notes that some risk exists and suggests homeowners consider mitigation. Results below 2.0 pCi/L are generally considered low risk.
Professional continuous radon monitors provide hour-by-hour data over the 48-hour test period. Your test report should show both the average reading and the individual hourly readings. It is normal for radon levels to fluctuate throughout the day; what matters is the average.
Context Matters
A result of 4.2 pCi/L is technically above the action level, but it is a very different situation than 15 or 20 pCi/L. Both require mitigation, and both are fixable with the same system, but the higher reading represents a more urgent health concern. Know your number and understand what it means before entering negotiations.
3. Your Negotiation Options
When elevated radon is discovered during the inspection period, you generally have four options.
Request the seller install mitigation before closing
This is the cleanest solution. The seller hires a professional radon company, the system is installed, and a post-mitigation test confirms levels are below 4 pCi/L before you close. You move into a home with a working radon system and verified low levels.
Request a closing credit
The seller provides a credit at closing to cover the cost of radon mitigation. This gives you control over choosing the contractor and scheduling the work. Get quotes before negotiations so you know how much to request. Typical systems run $1,200 to $2,500.
Negotiate a price reduction
Instead of a credit, ask for a reduction in the sale price equal to the estimated mitigation cost. This achieves the same financial result but through the purchase price rather than a credit. Your lender may have preferences about which approach to use.
Accept the condition and handle it yourself
In very competitive markets, you may decide to proceed with the purchase and install mitigation yourself after closing. This is a weaker position for you financially, but it may be necessary if the seller has multiple offers and will not negotiate.
4. What to Request From the Seller
When you present your negotiation request, being specific and reasonable strengthens your position. Here is what to include.
If requesting seller-installed mitigation: specify that the work should be done by a professional radon mitigation company, include a post-mitigation test showing results below 4 pCi/L, and include a system warranty. Ask for documentation of the installation and test results at closing.
If requesting a credit: get at least one or two quotes from local radon companies so your request is backed by actual numbers. A request for $1,500 to $2,000 is typical and reasonable for most homes in the Atlanta area. Use our radon mitigation pricing guide to understand what to expect. Present the quotes with your negotiation request.
Regardless of which option you choose, keep the tone professional and factual. Present the test results, reference the EPA action level, note the estimated cost of mitigation, and make your request. Avoid dramatic language about health risks. The numbers speak for themselves.
5. When Sellers Refuse
Sometimes sellers will not negotiate on radon, especially in a competitive market where they have multiple offers. If this happens, you need to make a decision based on the full picture.
Remember that radon mitigation is a one-time cost of $1,200 to $2,500. In the context of a home purchase that might cost $300,000 or more, this is less than 1% of the purchase price. If the home is otherwise exactly what you want and the only issue is radon, it may be worth absorbing the mitigation cost yourself.
On the other hand, if the seller is also refusing to negotiate on other inspection findings, the radon issue may be part of a larger pattern that tells you something about the transaction. Use your judgment and your agent's advice to decide how to proceed.
Keep Perspective
Radon is not a structural defect, a foundation problem, or an environmental contamination issue that costs tens of thousands to remediate. It is a gas that can be vented with a pipe and a fan. Do not let a fixable $1,500 issue cause you to walk away from the right home. At the same time, do not let a seller pressure you into skipping radon testing entirely.

6. Protecting Your Position
To protect your position throughout the negotiation process, keep these strategies in mind.
- Always include radon testing in your inspection contingency. Make sure the contract language gives you the right to test and negotiate based on results.
- Use a professional radon testing company, not a DIY kit. Professional results carry more weight in negotiations and cannot be questioned for accuracy or tampering.
- Get mitigation quotes before negotiating. Concrete numbers are more persuasive than vague estimates.
- Work with your real estate agent on the negotiation strategy. They know the local market dynamics and can advise on what is reasonable to request.
- Keep everything in writing. Verbal agreements about radon mitigation should be documented in the contract amendments.
- If the seller agrees to install mitigation, make post-mitigation testing a condition of closing. Do not close until you have verified the system works.
