FAQs Around Deck Building in Metro Vancouver

Whether it’s a modern composite deck, rooftop deck, or cedar backyard deck, we tailor every project to your space, lifestyle, and vision.

  • How much does a new deck cost in Coquitlam?

    Deck pricing depends on size, material, height, and design complexity. In Vancouver, most decks range from $45–$110 per sq ft, with cedar on the lower end and composite/PVC on the higher end. Rooftop decks or waterproof vinyl systems cost more but provide premium durability. We offer free, accurate quotes based on your specific project.

  • Do I need a permit to build a deck in Coquitlam?

    You may need a permit if:

    • Your deck is elevated or attached to the home
    • You’re adding structural components
    • You’re changing the footprint or height
    • You live in a strata or multi-family building

    We guide you through Coquitlam's permit requirements and handle documentation when needed.

  • What decking material is best for Coquitlam weather?

    Because Coquitlam has heavy rain and high moisture, the top-performing materials are:

    • Composite decking (Trex, TimberTech, Fiberon)
    • PVC decking (premium weatherproof option)
    • Vinyl membrane decking for balconies & rooftop decks
    • Western Red Cedar for a natural, West Coast look

    We help you choose the best option for durability, appearance, and budget.

  • How long does deck construction take?

    Most standard decks take 1–3 weeks to complete depending on size, design, and weather. Rooftop decks, multi-level decks, and waterproof membrane systems may take longer. We provide a clear timeline before beginning any project.

  • Can you repair an old deck or should I replace it?

    We can repair or restore older decks by replacing boards, fixing rot, strengthening framing, or resurfacing. However, if your deck has widespread rot, unsafe footings, or outdated framing, a full deck replacement is safer and more cost-effective long-term. We’ll assess your deck and recommend the best option.

  • What is the difference between vinyl decking and composite decking?

    Vinyl decking is a waterproof membrane used for balconies, rooftop decks, and sundecks where leak protection is essential.


    Composite decking is a low-maintenance board product for standard backyard decks and patios that looks and feels more like wood.


    We install both depending on your deck style and waterproofing needs.

  • Do you work with strata buildings and multi-family properties?

    Yes. We provide strata-compliant vinyl membranes, balcony replacements, railings, waterproofing systems, and safety upgrades for multi-family buildings across Coquitlam and the Lower Mainland.

  • How long do cedar, composite, and vinyl decks last in Coquitlam?

    Approximate lifespans:


    Cedar: 15–25 years with proper maintenance


    Composite: 25–40+ years


    PVC: 40+ years


    Vinyl membranes: 15–25 years depending on exposure


    Choosing the right material for Coquitlam's wet climate ensures maximum durability.

  • Do you offer free quotes?

    Yes—every project starts with a free, no-pressure, on-site quote where we assess your space, discuss materials, and provide accurate pricing.
