The best way to choose a deck builder in Metro Vancouver is to compare what is written in the quotes rather than the numbers at the bottom of them. Almost every deck that goes wrong was visible in the paperwork before the first board was cut — a scope that skipped what is under the existing deck, a ledger connection nobody described, or a warranty that was mentioned verbally and never written down.
Here is the checklist we would use ourselves, including the parts that are inconvenient for us to tell you.
Verify these five things before anything else
| What to verify | Why it matters |
|---|---|
| Municipal business licence | Has to be valid in the city where the work is happening, not just where the company is based. Metro Vancouver municipalities each license separately. |
| Liability insurance | Ask for the certificate, check the expiry date, check the coverage amount. If a post goes through a gas line, this is the document that matters. |
| WorkSafeBC coverage | Clearance letters are free and verifiable online. If someone is injured on your property and the contractor is not in good standing, that exposure can land on you. |
| Written workmanship warranty | Manufacturer warranties cover the boards. Workmanship warranties cover the build. They are different documents and the second one is the one people forget to ask for. |
| Projects you can actually see | Not a gallery — an address, or a client who will take a call. Ask for something built five years ago, not five months ago. Five months proves nothing about this climate. |
Any builder who is slow or vague on the first three should be off the list. These are not sensitive documents; they are routine.
Why deck quotes vary so much
Homeowners regularly get three quotes with a spread wide enough to look like a mistake. It usually is not. The quotes are for different work.
A complete quote for a rebuild accounts for: demolition and disposal of the existing structure, footings sized for the actual soil and load, framing, the ledger connection and its flashing, decking, railings, stairs, permits and drawings, waterproofing if anything below needs to stay dry, electrical if there is lighting, and an allowance for what gets found once the old deck is open.
A thin quote covers boards, railings and labour, and treats everything else as a change order after the deck is apart and you have no leverage. It is not cheaper. It is unfinished.
We wrote out what a full quote should contain, line by line, in what’s included in a deck quote. Print it and read the quotes against it. If a quote has no line items at all, you have learned what you needed to know.
The questions that actually separate builders
“What happens if you open it up and find rot?”
This is the single most useful question you can ask in Metro Vancouver, because on rebuilds it happens constantly — the surface looks tired and the frame underneath is finished. A good answer is specific: we stop, we show you, we price the additional work, you decide. A bad answer is “we’ll deal with it” or a flat refusal to discuss it. Get the answer in writing. More on the distinction in our deck repair guide.
“How does the deck attach to the house, and how is that connection flashed?”
The ledger is where decks fail and where houses rot. A builder who answers this fluently — how the siding is opened, how the flashing laps, how the fasteners are specified — has done it properly before. A builder who says “we bolt it on” has told you what you needed to know.
“Who is physically on site?”
The person quoting, an employed crew, or subcontractors they have not met? None of those is automatically wrong. Not knowing the answer is.
“What does the workmanship warranty cover, and for how long?”
Verbal warranties are worth exactly nothing at year three. Ask for the term, what is included, and what voids it.
“Do I need a permit for this, and what does my municipality require?”
A builder working regularly in your city should be able to categorise your project on the first visit. Requirements differ across the region — we have written up Vancouver, Burnaby, Surrey, New Westminster and Delta separately for that reason. Vagueness here often means they intend to build without one.
Red flags
- A quote with no line items. One number for the whole job means you cannot compare it to anything and cannot dispute it later.
- A large deposit up front. A deposit to hold a slot and cover material ordering is normal. A majority of the contract value before work starts is not.
- Cash-only, no written contract. No contract means no warranty, no recourse, and no permit.
- Pressure to decide today. Real builders have a schedule and can tell you where you would fall in it. Discount deadlines are a sales technique.
- No interest in what is under the existing deck. A builder who quotes a rebuild without looking underneath is quoting a job neither of you has seen.
- Reluctance to name the municipality’s requirements. Usually means the plan is to skip the permit.
Before you call anyone: do this first
You will get better quotes, and more comparable ones, if you arrive with the basics decided:
- Know roughly what size you need. Work from furniture and use, not a number — what size deck do I need walks through it.
- Have a material preference, or say you are open. Composite vs wood in BC and cedar vs pressure treated cover how each behaves in this climate.
- Know whether anything under the deck needs to stay dry. That single fact decides whether you are building a deck or a roof — see vinyl waterproofing.
- Have a real budget range. Not to disclose, but to know. Current Metro Vancouver ranges are in our deck cost guide.
- Sketch it, even badly. A free design tool is enough — we compared the ten best in free deck design tools.
Getting three comparable quotes
Give every builder the same brief: the same size, the same material, the same railing type, and the same instruction to price demolition, disposal, footings and permits explicitly. Ask each of them to write down what happens if they find rot. Then compare the documents, not the totals.
VS Deck & Rail builds composite, wood and vinyl decks and custom railings across Metro Vancouver — Vancouver, North Vancouver, West Vancouver, Burnaby, Richmond, Surrey, Coquitlam, Ladner, Tsawwassen and Delta. We open decks up before we quote them, we itemise, and we put the rot clause in writing.

Frequently Asked Questions
What should I check before hiring a deck builder in BC?
Five things, all verifiable before you sign: a valid business licence in the municipality the work is happening in, active liability insurance, WorkSafeBC coverage in good standing for anyone on your property, a written workmanship warranty with a stated term, and references or completed projects you can actually look at. Any builder who hesitates on the first three is telling you something.
Why are deck quotes so different from each other?
Usually because they are not quoting the same job. One includes demolition, disposal, footings, permit drawings and structural repair to what is underneath; another quotes boards and labour and treats everything else as an extra once the deck is open. The gap is not a discount, it is scope. Compare quotes line by line, and if a quote has no line items, that is the finding.
Do I need a permit, and whose job is it to get one?
It depends on the deck’s height, whether it attaches to the house and what is underneath it, and the rules differ by municipality across Metro Vancouver. A builder who works in your city should be able to tell you which category your project falls into on the first visit. Who files the permit is negotiable; who is responsible for the work meeting code is not.
What questions should I ask a deck builder?
Ask what happens if they open the deck and find rot, and get the answer in writing. Ask who is physically on site — the person quoting, an employee crew, or subcontractors. Ask what the workmanship warranty covers and for how long. Ask how the deck attaches to the house and how that connection is flashed. Ask for the address of a deck they built five years ago, not five months ago.
Are the cheapest deck quotes ever the right choice?
Occasionally, when a builder has genuinely lower overhead or is filling a gap in a schedule. More often a low number means something was left out — footings sized by guess, no allowance for what is under the existing deck, or a ledger connection that will be screwed to the siding instead of flashed into the wall. The cost of that shows up in year four, not on the invoice.
How long should a deck build take?
It depends on size, height, access and whether there is an existing deck to remove, so any builder quoting a duration before seeing the site is guessing. What you should expect is a written schedule with a start window, not a firm promise made on the phone. Ask what happens to the schedule if a permit review or a weather week runs long.
