At Lavalyn Inspections, we believe a home is more than walls and a roof—it’s a system that needs to work safely and efficiently. Duncan Sinclair brings over 30 years of engineering experience to every inspection, giving homeowners and buyers confidence that nothing is overlooked.

We believe that Inspectors should be certified in everything they inspect or operate to give clients confidence in our skills.
