Certifed decided long ago to use high quality materials on each system installed.
We use top of the line equipment and parts, all Radon-Away brand, on each mitigation system installed. Our RP 145 Radon fans are rated the most effective and efficient in the industry. Each system also includes a weather tight electrical shut off switch located within 3 feet of the fan. All piping materials consist of Schedule 40 core pvc assuring the system operates quietly and is up to code. Below are sketches of the 2 different types of systems we install, sub-slab and sub-membrane.
