Deck Resurfacing Tips from an Ottawa Home Inspector

Spring has finally arrived in Ottawa, and with the warm weather comes the urge to dust off the patio furniture and enjoy some time outdoors. For many homeowners, the backyard deck becomes the go-to place for family gatherings, barbecues, and lazy afternoons.

But if your deck is starting to show its age, you may be wondering:

Should I replace my deck, or can I simply resurface it?

As a trusted Ottawa home inspector, I come across decks in various states of repair during Ottawa home inspections. While resurfacing may seem like a quick and affordable DIY project, there are a few important factors to consider before laying down new boards.

✅ Can You Resurface Your Deck?

In many cases, the structure underneath your deck may still be sound—even if the surface boards are cracked, splintered, or weathered. Resurfacing can be a cost-effective option if done correctly. However, there's a common mistake that can lead to bigger issues down the road: installing new deck boards directly on top of the old ones.

❌ Why You Shouldn’t Double Up Deck Boards

1. Restricted Air Flow = Moisture Trouble

Ottawa’s climate throws a lot at your deck—snow, rain, humidity, and temperature swings. That’s why air circulation is essential. Deck boards are spaced to allow water drainage and airflow underneath. Doubling up reduces circulation, trapping moisture and speeding up rot and decay.

2. Shortened Deck Lifespan

Trapped moisture between old and new boards doesn't just affect the surface—it spreads to the structure and fasteners. This results in faster deterioration of all components. We've seen many resurfaced decks during Ottawa home inspections that had to be torn out entirely within just a few years due to this issue.

3. Composite Deck Warranties at Risk

Thinking of using composite boards for the top layer? Be careful. Most composite decking manufacturers require installation directly onto joists—not on top of old boards. Failure to follow this guideline may void the warranty, leaving you unprotected if problems arise.

🕵️ What Your Ottawa Home Inspector Recommends

Before you resurface your deck:

• ✅ Inspect the frame and joists for rot, shifting, or weakness

• ✅ Remove old decking boards before adding new ones

• ✅ Ensure proper spacing and ventilation for moisture control

• ✅ Consult a professional for guidance if you’re unsure

If you're planning a deck project this spring, book an Ottawa home inspection or home maintenance check to evaluate your existing structure. A professional Ottawa home inspector can help identify potential issues before you invest in materials or labor—saving you time, money, and future headaches.
