Radon is everywhere that uranium is breaking down below the ground. Most of the time, the buildings we’re in have a lower air pressure than the soil around them and act like a vacuum, sucking radon into the building through every tiny crack.
Your new build is more airtight than the house your Grandma had, so gases can get trapped in there. A well designed radon reduction system creates a vacuum below the lowest part of your home or building, and vents much of the gas above the roofline before it makes it inside.
Some new build homes have a passive system installed before completion. This is definitely a step in the right direction, but not usually a game changer for your radon exposure in real life. To guarantee success, we will typically add a new suction point, and ensure that your new system will pick up the slack, and bring you safer air to breathe.
