In 2007, Keith launched ProVantage Property Inspection Inc., an inspection company specializing in residential homes. On a regular basis, he crawls through and climbs over homes old and new, seeking out defects such as mouldy attics, leaking basements, and nonprofessional renovations. Because a home inspector sees only the tip of the iceberg in visual inspections, Keith’s knowledge of building science enables him to explain causes, risk, and remediation requirements in a way that clients can understand. Keith is a Registered Home Inspector (RHI) and a Certified Engineering Technologist (C.E.T) and is very pleased to add the BSSO designation as a milestone on his path of continuous learning.
