Why Homes in Durham Region Need Measurement, Not Guesswork
Durham Region includes a diverse mix of housing stock: older homes with character basements, newer airtight subdivisions, renovated properties, growing family neighbourhoods, and rural pockets near the Uxbridge border. Each type of home presents its own air quality profile.
Newer, more energy-efficient homes in communities like Ajax, Whitby, Pickering, and Clarington can retain elevated concentrations of radon, CO₂, and VOCs if ventilation is not properly balanced. Older homes may have different baseline conditions but are equally worth measuring.
RBM Group serves Durham Region as a core service area. Every visit begins with professional measurement, ends with a written report, and includes a clear explanation of findings against Health Canada guidelines. There is no obligation to proceed with any product or service until you are informed and comfortable.
