How It Works

Navigating radon concerns is straightforward with Martens Radon. From testing to installation, we guide you every step of the way.

Step 1: Get Your Home Measured

Schedule a professional radon test. We can perform this service, or you can use a DIY test kit.

Step 2: Determine Mitigation Needs

Radon is measured in picocuries per liter (pCi/L). The EPA recommends mitigation at 4 pCi/L or higher according to the EPA and is the level for action in Colorado residential transactions. The World Health Organizations suggests getting below 2.7 pCi/L for spaces you live in.

Step 3: Get Your System Cost

Every home is different – we start with a free on-site assessment, examining your foundation type, basement and/or crawlspace, layout, and electrical setup, and vacuum pipe routing.

Step 4: Install Mitigation System

If you are required to mitigate for a transaction or want to reduce risk for yourself and loved ones, we install the system.

Step 5: Verify System Function

After installation, we can retest to verify effectiveness. That ensures your system is working properly for your unique home. Some people just want a mitigation system installed and want to move on.
