Radon exposure can lead to serious health risks and is one of the leading causes of lung cancer. When it comes to the health and safety of your home, where you and your family spend most of your time, it's important to be thorough. Only a radon test can determine whether your home has dangerous radon levels, so contact your trusted Ontario radon contractor for a free estimate today.

Although no homeowner wants to increase cancer risks for family members, many people neglect to test their homes for radon, an invisible, odorless, cancer-causing gas that emanates from soil and rocks. Contacting a radon mitigation specialist to perform a radon test, or conducting your own test with a DIY radon test kit is the first step in protecting your family from hazardous levels of radon gas.
