When considering radon testing and mitigation, homeowners should budget between $749 and $2,500 for installation of a mitigation system, depending on various factors such as home size and radon levels. On average, most people pay around $1,000 to $1,500. It's also important to note that after installation, ongoing operational costs of around $15 to $30 per month may be incurred for system maintenance.
Before investing, ensure you assess your home’s radon levels and consult with certified professionals. It is also possible to perform radon tests yourself using long-term kits, which typically cost about $50, but hiring a professional can provide more accurate results and peace of mind.
