Designing effective radon reduction systems for multi-family buildings

Radon Mitigation

Maple Leaf Radon Defence provides radon testing in multi-family properties.

Installing a radon reduction system in large buildings requires extensive knowledge of building codes and construction designs. Things like HVAC systems, stairwells, elevator shafts, and complex foundations must be considered. The most common radon mitigation system is Active Soil Depressurization, but we will work with you to determine the best radon reduction method for your property. With experience designing radon mitigation systems for multi-unit buildings, you can count on Maple Leaf Radon Defence for effective reduction of radon levels and peace of mind. Once mitigation is completed, we will provide you with a certificate of completion and ensure that follow-up testing is completed.

If you need to have your building tested, learn more about our multifamily radon testing services and contact us today to schedule your test!
