PROVIDING QUALITY RADON MITIGATION SINCE 1985
The contractor shall conduct a thorough visual inspection of the building prior to initiating any radon mitigation work. The inspection is intended to identify building characteristics and configurations (e.g. large cracks in slabs, exposed earth in crawl spaces, open stairways to basements) and operational conditions (e.g. continuously running HVAC systems or operational windows) that might affect the design, installation and effectiveness of radon mitigation systems. As part of this inspection, clients should be asked to provide any available information on the building (e.g. construction specifications, pictures, drawings, etc.) that might be of value in determining the radon mitigation strategy.
Radon Systems installs approximately 1500 systems per year in residential/commercial properties and an additional 400 systems per year in new construction houses. Several large buildings have been mitigated by Radon Systems. Included in the list are the Ohio Statehouse; Garfield Elementary School; EPA building in Dayton, Ohio; The Grand Court retirement home in Findlay, Ohio; Kobacher House at Riverside Hospital; Meridian apartment complex in Columbus, Ohio; and several large apartment complexes.
