How do I confirm a Vancouver deck contractor's experience with composite?

Ask for photos of recent composite installations, references from composite projects completed in the last 2 years, and specific details about their experience with the composite brand you're considering. Not all deck contractors have equal experience with composite materials — the installation techniques, fastening systems, and thermal expansion considerations are different from cedar construction.

Request Recent Project Photos and References
Ask to see photos of at least 3-5 composite decks they've completed in Metro Vancouver within the past 24 months. Pay attention to details like clean, consistent board spacing, proper end-to-end board joints, smooth railing installations, and how they handled transitions around posts or obstacles. Request contact information for 2-3 recent composite clients and actually call them. Ask about the installation quality, timeline adherence, cleanup, and whether they've experienced any issues with board movement, fastener pop-ups, or color fading after the first year.

Test Their Technical Knowledge
A qualified composite installer should easily explain the differences between capped and uncapped composite, why hidden fastening systems (like Trex Hideaway or TimberTech CONCEALoc) are preferred over face-screwing, and how they account for thermal expansion in Metro Vancouver's temperature swings. They should know that composite boards expand and contract more than wood — requiring specific gap spacing between board ends and proper fastening techniques to prevent buckling. Ask about their experience with the specific brand you're considering (Trex, TimberTech, Fiberon) because each has slightly different installation requirements and warranty conditions.

Verify Manufacturer Training and Warranties
Many composite manufacturers offer contractor training programs and certification. While not mandatory, contractors who've completed TimberTech Pro or Trex Pro training demonstrate commitment to proper installation techniques. More importantly, ask if they're familiar with the warranty requirements for your chosen composite brand — many warranties are voided by improper installation, incorrect fasteners, or inadequate ventilation underneath the deck. A knowledgeable contractor will explain that composite decking still requires proper airflow underneath to prevent moisture buildup and potential mold growth on the underside.

Check Their Tool Setup and Material Sourcing
Composite installation requires specific tools that not all deck builders own — quality miter saws with fine-tooth blades for clean cuts, hidden fastening jigs, and proper drill bits for pilot holes. Ask where they source their composite materials and whether they maintain relationships with local suppliers like Rona, Home Depot Pro, or specialty decking distributors. Contractors who regularly install composite will have established supplier relationships and can often get better pricing than one-off purchases.

WorkSafeBC and Insurance Verification
Confirm their WorkSafeBC registration is current and that their liability insurance specifically covers composite deck installation. Some insurance policies exclude newer materials or installation techniques. This is especially important for elevated composite decks where installation errors could create safety hazards.

Red Flags to Watch For
Be cautious of contractors who claim "all decking is the same" or suggest face-screwing composite boards instead of using hidden fasteners. Avoid contractors who can't explain thermal expansion requirements or suggest that composite is completely maintenance-free (it still requires periodic cleaning). If they quote significantly below market rates ($55-$100 per sq ft installed for quality composite), they may be cutting corners on materials, proper fastening systems, or structural requirements.
