Identify, evaluate, and confidently guide clients through PWF transactions
Nothing derails a transaction faster than a foundation surprise. When your buyer discovers mid-inspection that they're purchasing a wood foundation home—and no one mentioned it—you've lost their trust, possibly the deal, and almost certainly the referrals that come from confident clients.
Here's what you need to know: Permanent Wood Foundations (PWFs) represent about 3% of Alberta homes. That means you'll encounter roughly 1 in every 30 transactions. These aren't defective homes—over 300,000 PWF homes exist across North America, and they're approved by FHA, VA, and major lenders. A well-built PWF can last 75-100 years. But a poorly built or maintained one? You're looking at $50,000-$100,000+ in repairs.
The difference between a successful PWF transaction and a disaster comes down to whether you—the agent—know what you're looking at and how to communicate it.
PWF homes in Alberta typically sell for $40,000-$50,000 less than comparable concrete foundation homes. For sellers, that means proper disclosure and pre-listing inspection can mean the difference between a 21-day sale at 97% of asking and 45+ days on market with a $35,000 price reduction. For buyers, it means opportunity—or a $68,000 repair bill if you don't know what to look for.
Permanent Wood Foundations use pressure-treated lumber rated for ground contact (0.6 pcf retention) and are built to CSA S406 standards. When built correctly, they're warmer, faster to construct, and handle Alberta's freeze-thaw cycles better than concrete.
Proper lumber treatment (0.6 pcf minimum), adequate drainage (125mm gravel layer + functional sump pump), and ongoing maintenance. Miss any one of these, and the foundation will fail.
You can spot most PWFs before the inspection report arrives—treated plywood at grade, wood studs in the basement, greenish tint on lumber, and no visible concrete below grade. Knowing what you're walking into means you can prepare your client.
A standard home inspector may not have PWF training. Budget an extra $200-$400 for a PWF specialist who will do intrusive inspection—removing baseboards, probing for moisture, and verifying treatment specifications.
Buyers who discover PWF during inspection walk away. Buyers who know upfront and see clean documentation become confident purchasers. Disclose early, inspect proactively, and you'll close deals that other agents lose.
