Preserved wood foundation (PWF) inspections
Preserved wood foundation (PWF) inspections.
Most Alberta basements are concrete, but many homes have a permanent or preserved wood foundation (PWF). Wood in contact with soil is prone to moisture, rot and mould over time. Our PWF inspectors and engineering partners assess the foundation and estimate its remaining service life before you buy.

Why it matters
Why a PWF needs its own inspection
Pressure-treated wood foundations became possible in the 1960s. They can make a warmer basement, but moisture is their enemy. Controlling surface water around the foundation is critical, and any buyer should have a PWF assessed and all drainage issues corrected before purchase.
