Deck Building & Repair in Vancouver
Decks in this climate almost never fail where people look. The surface boards get all the attention and the staining, while the two things that actually end a deck early — the ledger connection and the joist ends — sit hidden and wet.
Ledger attachment and flashing
The ledger is the board bolting the deck to the house, and it carries a large share of the load. Two things go wrong: it is nailed rather than through-bolted into the rim joist, and it is fitted without flashing above it. The second is the more common and the more destructive.
Without flashing, water runs down the wall, sits in the joint between ledger and sheathing, and rots the house from the outside in. By the time it shows indoors the repair is structural. Any deck of unknown history gets this checked first, because everything else is cosmetic by comparison.
Inspecting joists for rot
We look at the joist ends where they meet the ledger and the beam, the tops of joists under the gaps between boards, and any point where a post meets the deck frame. Water sits in exactly those places. A screwdriver pushed into sound timber stops; into rot it sinks, and that is the whole test.
The surface boards can be replaced any time. If the frame beneath them has gone, new decking is money spent on top of a problem — and it hides the evidence for another five years. That is why we open a section before quoting rather than pricing from a photograph of the surface.
Decking material comparison
Pressure-treated softwood is cheapest and needs the most maintenance. Cedar is the traditional local choice, weathers beautifully, and still wants re-oiling. Composite costs considerably more up front, never needs staining, and will not rot — but it moves with temperature, gets hot in full sun, and it looks like composite.
In this climate the honest comparison is total cost over fifteen years including the weekends you spend on it. Composite usually wins on that arithmetic for a large flat deck; cedar tends to win where the deck is small, visible, and part of how the house looks.
Permits for decks over 600mm
Municipalities here generally require a permit once a deck is raised more than a certain height above grade, and the threshold and process differ between Vancouver, Burnaby, Surrey and the rest. Guard requirements step up with the drop below as well.
We check the requirement for your address rather than assuming it matches the last job. Unpermitted structural work is the kind of thing that surfaces during a sale, at the worst possible moment and at your cost — so where a permit applies, we say so even though it makes the job slower and dearer.
What this costs
$1,400–$14,000 for built-ins, trim and stair work
Quoted after a site visit, materials separate. Trim and baseboard runs start around $1,400; a full alcove built-in in a heritage home, scribed to out-of-square walls, runs toward the top of the range. Decks are quoted separately and typically start at $22,000.
Materials are always separate from labour and passed on at cost. Quotes are free and written, and the full rate card is published rather than given out on request.
Common questions
How do I know if my deck is unsafe?
Check the ledger where it meets the house for flashing above it, and push a screwdriver into the joist ends — sound wood stops it, rot lets it sink. Also test whether guards move when you lean on them. Those three checks catch nearly everything that matters, and none of them involve the surface boards.
Cedar or composite for Vancouver rain?
Composite will not rot and needs no staining, but costs more up front, moves with temperature and looks like composite. Cedar is the local classic, weathers well and wants re-oiling. Over fifteen years including your own weekends, composite usually wins on a large deck and cedar on a small visible one.
Does a new deck need a permit?
Generally yes once it is raised more than a certain height above grade, and both the threshold and the process differ by municipality here. We confirm the requirement for your specific address before starting. Unpermitted structural work reliably reappears during a sale, which is the worst time to deal with it.
