Cornerstone has been trusted by home buyers to help them make informed buying decisions. Our home inspections typically range from 2.5-3.5 hours depending on the size of the house or condo. You are invited to follow along with your inspector as they perform their inspection. We have achieved the distinction of Certified Master Inspector as determined by the Master Inspection Certification Board. All Cornerstone Inspectors are trained to these standards and operate under a Certified Master Inspector.
