The right Langley deck builder builds decks as a main line of work, knows whether your home is in the City or the Township of Langley, takes care of the permit, carries liability insurance and WorkSafeBC coverage, and puts everything in a written, itemised quote. Get three quotes for the same deck, look at each builder's recent decks and talk to a past client before you sign. Keep the deposit modest and tie the remaining payments to finished stages of the work.
This guide covers what to check, what to ask and what a deck costs in Langley, so you can hire with confidence.
The short list
Before you hire a deck builder in Langley, make sure they:
- Build decks regularly. Ask to see decks they finished in the last year or two, ideally in Langley or nearby.
- Know your municipality. The City and the Township of Langley have separate building departments and rules.
- Handle the permit. Drawings, the application and the inspections should be part of the job.
- Carry insurance and WorkSafeBC coverage. Ask for a certificate of insurance and a WorkSafeBC clearance letter.
- Quote in writing. Size, footings, framing, decking product, railings, stairs, permit, cleanup, timeline and payment schedule.
- Give a written workmanship warranty. This is separate from any warranty on the boards themselves.
City or Township? Start with your address
Langley is two municipalities. The City of Langley is the compact urban centre. The much larger Township of Langley wraps around it and takes in Willoughby, Walnut Grove, Murrayville, Brookswood, Fort Langley, Aldergrove and the rural areas from the Fraser River down to the US border.
Each has its own council, bylaws and building department, so the rules for your deck depend on which side of the line you live on. A quote based on the wrong municipality's rules can lead to surprises once the permit application goes in.
Both expect a permit for a new deck. The City of Langley lists building, covering or enclosing a porch or sundeck as work that needs a building permit, with no height exemption stated. The Township's building bylaw requires a permit for all construction. Plan on a permit for most decks in Langley, including a roof over an existing deck. See Langley deck permit rules for details and links to both municipalities, and our BC deck permit guide for how permits work across the region.
A good Langley deck builder asks for your address early and tells you which office the permit goes through. If a builder says your deck doesn't need a permit, confirm it with the municipality before you rely on it.
What Langley neighbourhoods ask of a deck builder
Langley runs from brand-new subdivisions to farmland, and the builder's job changes with the lot.
Willoughby and Yorkson. Newer homes on tighter lots, many with a small builder-grade deck that owners now want to extend, cover or rebuild in composite. Side-yard setbacks and privacy from the neighbours shape the design. Townhomes usually need strata approval as well as a permit, so check with your strata before quotes come in.
Walnut Grove, Murrayville and Brookswood. Established homes, many with original decks now due for replacement, and plenty of tall trees. Shade and fallen needles hold moisture, so low-maintenance boards, good drainage and proper gaps between boards matter. Both municipalities have tree protection rules, so check before a builder removes a tree or cuts roots to make room for footings.
Fort Langley. Older and character homes on smaller lots, where a deck that suits the house matters more than the biggest possible footprint.
Aldergrove and the rural Township. Acreages and farms with room for large decks, covered outdoor kitchens and hot tub decks. About three-quarters of the Township is in the Agricultural Land Reserve, and rural lots often have septic fields and wells the deck has to stay clear of. Ask your builder to confirm early whether any extra approvals apply to your property.
What a good deck builder takes care of
Hiring a professional is about more than carpentry. On a typical Langley deck, the builder should handle:
- Design and drawings for the permit, sized to how you'll use the deck: dining, lounging, a barbecue spot or a hot tub.
- Footings suited to the soil. Concrete piers are common, and helical screw piles are often used where the ground is soft or wet.
- The ledger connection to the house, flashed so water can't get behind it. In our wet climate, this joint decides how long both the deck and the wall behind it last.
- Framing that suits the boards. Composite and PVC usually need closer joist spacing than wood, and joist tape helps protect the frame from rot.
- Guards and stairs to code. Under the BC Building Code, a deck more than 600 mm (about 2 ft) above the ground needs a guard at least 900 mm high, rising to 1,070 mm once the deck is more than 1.8 m up.
- Inspections, cleanup and hauling away the old deck, if there is one.
Roofs, second-storey decks and hot tubs often need engineered drawings. Ask whether your design needs an engineer and whether that cost is in the quote.
Check these before you hire
Deck experience, not just general renovation. Online directories list painters, flooring installers and handymen under "deck contractors". Look for a builder who does decks as a main line of work and can show recent examples like yours, whether that's a composite rebuild, a raised deck or a covered patio.
References. Ask for two or three recent clients, ideally in Langley or nearby, and call at least one. Ask whether the job finished on budget and how the builder handled surprises.
Business licence. The builder should hold a valid business licence for the municipality where the work is done.
Insurance. Ask for a certificate of liability insurance and check the dates.
WorkSafeBC. Ask for a clearance letter, or request one yourself for free on the WorkSafeBC website. It confirms the builder's account is active and in good standing, so the crew is covered if someone is hurt on your property.
Licensing in BC. BC doesn't issue a provincial licence for deck builders or renovation contractors. Trade certificates such as Red Seal carpentry are a plus, but references and recent work tell you more.
Warranty. Ask how long the workmanship warranty is and get it in writing. Board warranties are separate and usually depend on the boards being installed to the manufacturer's instructions, which is one more reason to hire someone who builds with your product often.
Questions to ask each Langley deck builder
- Is my address in the City or the Township, and will you apply for the permit?
- How long are permits taking right now?
- How will the deck attach to the house, and how will you flash the ledger?
- What footings will you use, and how deep?
- What joist spacing do my boards need, and will you use joist tape?
- Who will be on site each day: your own crew or subcontractors?
- If you find rot or hidden damage when the old deck comes off, how will you price the extra work?
- What's the payment schedule, and how much is the deposit?

What a deck costs in Langley
Langley prices sit close to the Lower Mainland average. These are typical installed costs for a low deck, before railings, stairs, permits and GST:
| Decking | Installed cost per sq ft |
|---|---|
| Pressure-treated wood | $35 to $65 |
| Cedar | $50 to $85 |
| Composite | $60 to $100 |
| PVC | $75 to $120 |
Two examples:
- A 12 x 16 ft ground-level composite deck with an aluminum railing and a few steps: about $14,500 to $27,000, plus the permit.
- A 300 sq ft raised composite deck with an aluminum railing, a full flight of stairs and the permit: about $27,500 to $56,500.
Height, glass railings, roofs and removing an old deck all push the price up. For a range based on your own size, height and material, try the deck cost calculator, and see deck costs in the Lower Mainland for the full breakdown.
Red flags
- They say your deck doesn't need a permit, or suggest skipping it to save money.
- They want a large deposit, or cash only, before any work starts or the permit is issued.
- The quote is one line, such as "composite deck, $18,000", with no details.
- They can't show recent decks or give you references.
- They push you to sign today to "hold the price".
- They can't show proof of insurance or a WorkSafeBC clearance letter.
When to start looking
Langley deck builders are busiest from spring through summer. If you want a deck ready for summer, start getting quotes in fall or winter, while builders have time for site visits. Permits often take several weeks, and longer for covered or engineered decks. See the best time to build a deck in BC for a month-by-month plan.
