How much does it cost to level a sinking deck in Dieppe NB?

Leveling a sinking deck in Dieppe typically costs $500–$3,000+ depending on what's causing the problem — and in the Moncton/Dieppe area, freeze-thaw heaving is almost always the culprit.

The price range breaks down roughly like this: if it's a minor issue with one or two posts shifting, you're likely looking at $500–$1,500 for a contractor to lift, re-level, and stabilize. If the footings themselves have heaved or failed — meaning they weren't deep enough to begin with — you're looking at $2,000–$5,000 for proper structural repair, which may include excavating and replacing footings entirely.

Why Dieppe Decks Sink

The Moncton/Dieppe area sits in the 1.2-metre frost depth zone. Any footing shallower than that will heave over winter as the ground freezes and expands. Many older decks in the area were built with deck blocks or shallow poured footings — both of which are a recipe for exactly what you're describing. After a few seasons of our 100+ freeze-thaw cycles, those footings shift, and the deck follows.

The other common cause is post rot at ground level. If posts were set directly in concrete without proper drainage, moisture gets trapped and the wood deteriorates from the bottom up. This looks like settling but is actually structural failure — and it needs to be addressed before someone gets hurt.

What a Repair Typically Involves

A contractor will first diagnose whether it's a footing issue, a post issue, or both. Minor leveling jobs involve temporarily supporting the deck, adjusting post heights with post bases or shims, and re-securing connections. More serious repairs mean digging down to 1.2m, pouring new concrete tube footings, and installing new posts with proper hardware. If the ledger board (where the deck attaches to your house) has shifted, that adds complexity and cost.

Practical Tips Before You Call

Take a look under your deck and check a few things: Are the posts sitting on blocks or in the ground? Is there visible rot at the base of any posts? Is the ledger board still flush against the house? Photos of these areas will help any contractor give you an accurate estimate faster.

This is definitely a hire-a-pro situation — leveling a deck involves temporarily loading the structure, which can be dangerous without experience. It also often requires a building permit in Dieppe if structural components are being replaced, so make sure your contractor pulls the necessary permits.

New Brunswick Decks can match you with a local Dieppe/Moncton area deck contractor for a free estimate — it's a good idea to get two or three quotes since repair scope can vary quite a bit once someone gets eyes on the actual footings.
