If your deck boards look rough, you don’t automatically need a full rebuild.

But if the *structure* is compromised — ledger rot, failing footings, unsafe guards — resurfacing is just putting lipstick on a problem.

This is a practical guide for homeowners in Kitchener-Waterloo-Cambridge (KWC) to decide rebuild vs resurface, based on a quick inspection.

Useful starting points:

The fast rule of thumb

Step 1: Do the 15-minute deck inspection (checklist)

Bring a flashlight. If you can access under the deck, even better.

A) Bounce + movement test (structure)

If the deck moves as a unit, it often points to footing/post issues or missing lateral bracing.

B) Ledger board and house connection (attached decks)

This is the highest-risk area.

Look for:

FAQ

Can I resurface now and rebuild later?

Sometimes, but it can be false economy. If you suspect structural problems, resurfacing can delay the rebuild while the underlying damage gets worse.

Will resurfacing require a permit?
