The boards you walk on are not the important part of a deck’s construction, even though they’re what everyone notices first. Framing, footings, and how the structure attaches to your home determine whether a deck lasts or needs rebuilding in five. We treat the structural work as the actual project and the decking material as the finish layer on top of it.
What that structure needs to support varies a lot by design. A ground-level patio deck sits on footings with minimal engineering involved. A raised deck attached to your home can carry more load and more code requirements. A multi-level deck adds stairs, several guard rail heights, and more places for water to find its way in if it isn’t built right the first time.
Upfront price and long-term cost are two different questions, and homeowners usually only ask the first one. Pressure-treated wood and cedar cost less to install, but wood needs re-staining and sealing every two to three years to hold up against BC’s wet climate, which is an expense that adds up steadily over a decade. Capped composite and PVC decking cost more upfront, but need little beyond occasional cleaning once installed. If your deck sits over living space (a garage or a lower-level room), a waterproof membrane system adds cost but is often the only way to keep that space dry underneath, wood decking boards are obviously not watertight. We’ll walk through the trade-offs for your specific project so you can make the best informed decision.
Deck construction is outdoor work, so weather affects the schedule more than it does most renovation projects, particularly through a Fraser Valley winter. Beyond weather, permit timing is the other major variable: municipal review for a deck permit typically takes weeks, and any deck requiring a professional engineer (for an unusual span or a heavy load like a hot tub) adds design time on top of that review. A small ground-level deck can sometimes be finished within days of the crew showing up, once material is on hand. A raised or multi-level deck attached to your home takes longer because it involves footings, framing, ledger board attachment, and inspection sign-offs.
Every deck gets designed around your yard’s grade, how the space will actually get used, and what fits best within your landscape. What follows covers the types and materials we build most often across the Fraser Valley.
A ground-level deck sits low enough that code typically doesn’t require a guard, which keeps both the structure and the permitting simpler. It’s a common starting point for a patio-style outdoor space and one of the few deck types that can sometimes be built without a permit at all, depending on height and footprint.
Capped composite and PVC boards are the best choice for most of the decks we build, largely because they hold up to BC’s rain and freeze-thaw cycling without the recurring maintenance wood requires. Current colour trends lean toward muted, natural wood-like tones rather than the high-contrast-streaked composites that were popular a few years ago, often paired with aluminum or glass railings for a cleaner look.
A deck built over a garage, a lower-level suite, or any other living space needs a waterproof membrane on top, not just boards with gaps between them. This is a distinctly BC specialization given how much rain the Lower Mainland gets, and it calls for a different skill set than standard deck framing: get the membrane, drainage, or flashings wrong and water eventually finds its way in regardless of how good it looks on to the naked eye.
Aluminum, glass, cable, and wood railing systems are all code-compliant options above the relevant guard height, and the choice usually comes down to style and budget rather than performance. Patio covers and pergolas get bundled in fairly often too, extending the usable season on a deck that would otherwise sit empty through the wetter months.
A deck moves through the stages below in order, though which ones apply depends on height, attachment, and whether an engineer is involved.
Most BC municipalities require a permit once a deck rises more than 24 inches above grade, attaches structurally to your home through a ledger board, supports a roof or enclosure, or exceeds 100 sq’. A small, low, freestanding deck often falls outside all of those triggers and can proceed without one. A deck built on its own doesn’t usually trigger Licensed Residential Builder requirements under the Homeowner Protection Act, since that legislation targets new home construction and major renovations rather than a standalone deck. If your deck is part of a larger addition, though, that broader project may carry its own licensing and warranty obligations. Renovation work over $1,000 legally requires a written contract in BC covering scope, price, and warranty terms. We include one on every project by default.
It comes down to height, how it’s attached, and how big it is. A deck over 24” above grade, attached to your home, covered by a roof, or larger than 100 sq’ generally needs one. A small, low, freestanding deck often doesn’t. We’ll confirm which category yours falls into before we start.
Yes, significantly. A deck over living space needs a proper waterproof membrane system on top rather than standard decking boards because the goal is keeping the space below completely dry. That’s a different build than a standard ground-level deck, and the design has to reflect that from day one.
A small ground-level deck can sometimes be finished within days once materials are on hand. A raised or multi-level deck attached to your home takes longer, since footings, framing, and inspections all add time, and weather can push things further depending on the season.
Yes. Where a permit or engineered drawings are required, we prepare and submit them as part of the project. Finding an engineer or chasing a municipal sign-off never lands on your to-do list.
Material choice, size, height, and whether waterproofing is involved all move the number more than almost anything else does. A basic ground-level wood deck costs the least upfront; a raised composite or PVC deck with a waterproof membrane underneath costs considerably more. We will be upfront with all the costs involved before starting construction.
