Radon Mitigation: A Promise That Isn't Always Kept
Radon is a silent, colorless, odorless radioactive gas that is the second leading cause of lung cancer in the United States [citation:EPA]. When a radon test reveals elevated levels, homeowners turn to professional radon mitigation contractors to install a system that will reduce radon below the EPA's action level of 4 pCi/L. Most reputable contractors offer a performance guarantee: after installation, they will retest the home and, if levels remain high, they will adjust the system or refund the customer. But what happens when the contractor refuses to honor that guarantee? Or when the retest shows failure and the homeowner simply wants out of the contract? You have legal rights. This guide explains how to cancel a radon system installation after a retest, what state laws protect you, and the practical steps to exit a radon contract without losing thousands of dollars.
The Retest Failure: When Your Radon System Doesn't Work
A radon mitigation system typically uses sub-slab depressurization (SSD) to draw radon from beneath the foundation and vent it safely above the roofline. After installation, a radon retest is critical to confirm the system's effectiveness. If the retest still shows radon levels at or above 4 pCi/L, the system is not performing as promised. Many contracts include a clause that gives the contractor a second chance to adjust the system (e.g., adding a second fan, sealing cracks, extending piping). However, if the contractor repeatedly fails to achieve the target level, the homeowner may have grounds to cancel the contract entirely. The key question is: does the contract guarantee a result, or just an effort? Most state radon laws and voluntary standards (e.g., the American Association of Radon Scientists and Technologists (AARST)) require that mitigation systems meet the EPA's guidelines, but not all contracts explicitly guarantee a specific radon level. If the contractor promised in writing that the system would reduce radon below 4 pCi/L, and that promise is not met, you may be able to cancel for breach of warranty [citation:AARST].
Your Legal Right to Cancel: State Laws and Cooling-Off Periods
Your ability to cancel a radon system contract depends on the laws of your state and the circumstances of your signing. Here are the most important legal protections available.
Federal Trade Commission Cooling-Off Rule
If you signed the radon mitigation contract at your home (or any location that is not the contractor's permanent place of business), you are likely protected by the FTC's Cooling-Off Rule. This federal law gives you three business days to cancel any contract for more than $25 signed in your home. The contractor must provide a written notice of your right to cancel at the time of signing, along with a cancellation form. This right is independent of the retest outcome. If the contractor fails to provide this notice, the cancellation period may be extended. You can cancel for any reason during this window [citation:16 CFR Part 429].
State-Specific Radon Laws and Consumer Protections
Several states have enacted laws specifically governing radon mitigation contractors and their contracts. Here are notable examples:
- Illinois: The Illinois Radon Awareness Act requires radon mitigation contractors to be licensed by the Illinois Emergency Management Agency (IEMA). Contracts must include a notice that the system may require ongoing maintenance and that radon levels may vary. If the contractor fails to meet the performance standard stated in the contract (typically a post-mitigation test below 4 pCi/L), the contractor must correct the deficiency at no cost to the homeowner. If they fail to do so within a reasonable time, the homeowner may cancel the contract and receive a full refund [citation:420 ILCS 44/40].
- Colorado: Colorado's Radon Contractor Standards require that mitigation systems be installed in accordance with EPA protocols. While Colorado does not have a specific cooling-off period for radon contracts, the Colorado Consumer Protection Act covers unfair or deceptive acts in the sale of radon mitigation services. If the contractor misrepresents the system's effectiveness or fails to deliver the promised performance, the homeowner may have a claim for treble damages [citation:Colo. Rev. Stat. § 6-1-105].
- Ohio: Ohio's Radon Licensing Program requires all radon mitigation contractors to be licensed by the Ohio Department of Health. The contract must include a provision that the homeowner may cancel the contract within three business days for in-home sales (consistent with FTC rules). Additionally, if the post-mitigation test exceeds the guarantee level, the contractor must take corrective action within 30 days or refund the customer [citation:Ohio Admin. Code 3701-71-11].
- Pennsylvania: The Pennsylvania Radon Certification Act requires contractors to follow AARST standards. If the system fails to reduce radon to the guarantee level, the homeowner may demand a refund or cancellation. The Pennsylvania Department of Environmental Protection investigates complaints and can order refunds [citation:63 P.S. § 2004].
Common Law Right to Cancel for Breach of Warranty
If the contractor expressly warranted that the radon system would reduce radon levels below a certain threshold (e.g., 4 pCi/L), and the retest shows levels above that, you have a clear breach of an express warranty. Even if the contract does not contain an express guarantee, you may have an implied warranty of fitness for a particular purpose: the system was intended to reduce radon, and if it fails to do so, it is not fit for its intended use. In many states, a buyer can revoke acceptance of a product or service that fails to conform to the contract. This revocation entitles you to cancel the contract and recover your money. However, you must act promptly and provide the contractor with a chance to cure the defect [citation:UCC § 2-608].
Beyond Retest Failure: Other Grounds for Cancellation
Sometimes the retest reveals no failure, but you still want to cancel for other reasons. Here are additional legal grounds.
Misrepresentation or Fraud by the Contractor
If the radon contractor made false statements that induced you to sign the contract — for example, claiming that the system would require no maintenance or that it would eliminate all radon permanently — you may have grounds to rescind the contract due to fraudulent inducement. This is especially common with door-to-door sales. If the salesperson told you that the system would lower your radon to 2 pCi/L, but the contract only guarantees 4 pCi/L, you may have a misrepresentation claim. Document all verbal statements and any marketing materials that contradict the contract [citation:FTC v. Radon Free, Inc.].
Failure to Obtain Required Permits or Licenses
Many states require radon mitigation contractors to hold a license or certification, and some local jurisdictions require building permits for the installation. If the contractor failed to obtain the necessary permits (e.g., to cut a foundation slab or discharge vent near a window), the installation may be illegal. In such cases, you have a right to cancel the contract because the contractor breached a fundamental requirement. Moreover, if the contractor is unlicensed, you may be able to void the contract under state licensing laws. For example, in Illinois, performing radon mitigation without a license is a violation of the Radon Awareness Act, and any contract entered into by an unlicensed contractor is voidable [citation:420 ILCS 44/30].
Breach of Contract for Failure to Complete on Time
If the contract specified a completion date and the contractor missed it without a valid excuse, you may have the right to cancel. Many radon mitigation systems are installed in one or two days. If the contractor starts the job but does not finish, or delays unreasonably, you can demand completion or cancellation. Check your contract for a 'time is of the essence' clause, which strengthens your right to cancel for delay.
How to Cancel a Radon System Installation Contract
If you have determined that you have a legal right to cancel, follow this step-by-step action plan to protect yourself and maximize your chances of a full refund.
- Review your contract immediately: Find the cancellation clause, notice period, and contact information for the contractor. Also identify the performance guarantee and any warranty terms regarding radon levels.
- Conduct your own independent retest: Before taking action, hire a different certified radon tester to conduct a retest (not the contractor's own tester). This provides third-party evidence of failure.
- Send a written cancellation notice: Use certified mail with return receipt requested. Include your name, address, contract date, system installation date, and a clear statement that you are canceling because the system failed the retest. Attach the retest results.
- Cite the specific legal grounds: Reference the contract's performance guarantee, any state law or FTC rule that applies, and demand a full refund of all amounts paid.
- Set a deadline for response: Give the contractor 10 business days to confirm cancellation and issue a refund. Warn that failure to respond may result in a complaint to your state attorney general and the Better Business Bureau.
- If the contractor refuses or ignores you: File a complaint with your state radon program (often part of the health department or environmental agency), the FTC, and the BBB. Also contact your state's consumer protection office.
- Consider mediation or legal action: If the amount involved is significant (often $1,500 to $3,000 for a radon system), consult a consumer protection attorney. Many states allow recovery of attorney's fees if you prevail.
How to Avoid Radon Contract Pitfalls in the First Place
The best way to avoid needing to cancel is to choose a reputable contractor and review the contract carefully before signing. Here are practical tips.
- Always verify the contractor's license and certification: Check with your state's radon program (usually the department of health or environmental quality).
- Insist on a written performance guarantee: The contract should state the guaranteed radon level (e.g., below 4 pCi/L) and what happens if the system fails (e.g., free corrective measures or refund).
- Do not pay in full upfront: Standard industry practice requires no more than one-third of the total cost as a deposit before work begins. The final payment should depend on a successful retest.
- Understand the retesting protocol: The contract should specify who conducts the retest, when it must be done (typically within 30 days of installation), and what testing method is used (a 48-hour continuous monitor is recommended).
- Get all verbal promises in writing: If the salesperson made any claims about energy savings, maintenance, or effectiveness, ask that they be added to the contract as a warranty.
- Research the contractor: Check online reviews, the BBB rating, and any complaints filed with your state's attorney general. Be wary of contractors with poor reviews regarding warranty responsiveness.
- Ask about the contractor's insurance: Ensure they have general liability and workers' compensation insurance to protect you in case of damage or injury during installation.
