Custom Deck and Fence Installation Across Toronto and the GTA

OCM Excavation & Construction designs, builds, and installs custom decks for homeowners and builders across the Greater Toronto Area. From small backyard cedar decks to multi-level composite outdoor living spaces, our crew handles every stage — design, permits, footings, framing, decking boards, railings, stairs, and finish. We’ve delivered decks in Vaughan, Markham, Richmond Hill, King City, Newmarket, Aurora, Barrie, Brampton, Mississauga, and Toronto.

Deck Materials We Work In

Pressure-treated wood — the most affordable and widely used option for residential decks. Our pressure-treated decks come with a 10–15 year service life with proper maintenance, and they’re rated for direct-ground contact.

Western Red Cedar — naturally resistant to rot, insects, and decay. Warm, premium look. Holds stain beautifully. Cedar is the upgrade most homeowners want for a high-end residential deck.

Composite (Trex, TimberTech, Fiberon) — virtually zero maintenance, 25-year warranties, never needs staining or sealing. Higher upfront cost, lower lifetime cost. Great for clients who don’t want to refinish every two years.

PVC and vinyl decking — fully synthetic, maximum durability, ideal for shaded or wet areas. Won’t fade or warp.

Our Deck Building Process

  • Free on-site consultation — we visit your property, measure, discuss your vision, and give you a written quote within 24 hours.
  • Design and material selection — we help you choose materials, layout, and finishes that fit your budget and style.
  • Permits and zoning — we handle all building permits, setback requirements, and inspections. Toronto, Vaughan, Markham, and most GTA municipalities each have different rules; we know them.
  • Site preparation and footings — we excavate and pour concrete footings or install helical piles, ensuring your deck is structurally sound and code-compliant.
  • Framing, decking, and finishing — full build by experienced carpenters, including stairs, railings, lighting, and any built-in features (benches, planters, privacy walls).
  • Final inspection and walkthrough — we ensure everything passes municipal inspection and walk you through care and maintenance.

Typical Deck Project Costs in the GTA

Every deck is different, but for ballpark planning: small pressure-treated decks (10×12 ft) typically start around $5,000–$8,000 installed. Mid-size cedar decks with railings and stairs run $12,000–$20,000. Large composite decks with multi-level designs, lighting, and built-in features can range $25,000–$50,000+.

Deck Building FAQ

Do I need a permit for a deck in Toronto or the GTA?

In most GTA municipalities, decks higher than 24 inches off the ground or attached to the house require a building permit. We handle all permit applications as part of every full-build project.

How long does it take to build a deck?

Small to mid-size decks typically take 3–7 working days from breaking ground to final inspection. Larger or multi-level decks can take 2–3 weeks. Permit approval usually adds 2–4 weeks before construction begins.

What deck material is best for the Canadian climate?

Cedar and composite hold up best in the GTA’s freeze-thaw cycles. Pressure-treated is the most affordable but requires more maintenance. We’ll recommend based on your budget, sun exposure, and how often you want to refinish.

Do you offer financing?

We work with several home-improvement financing partners. Ask for details when you request your quote.

What warranty do you offer?

2-year workmanship warranty on every deck we build, plus the full manufacturer warranty on materials (composite decking typically 25 years; cedar and pressure-treated as per supplier).
