Our Deck Building Services

Custom Deck Design Tailored to Your Backyard

Every backyard is different. Our designers work with your lot, your home's architecture, and your personal style to create a custom design you'll love. From simple ground-level platforms to multi-level decks, larger layouts, and rooftop decks, we shape every aspect of the plan around your specific needs and budget. Privacy screens, integrated lighting, pergolas, and built-in benches — attention to detail at every step.

New Deck Installation and Construction

Building decks is what we do every week. We handle deck construction, deck framing, and full deck building from layout to finishing touches. Our crews follow local building codes and Ontario Building Code requirements so your new deck passes inspection without delays. The end result is high-quality decks that perform for many years.

Decking Materials and Premium Finishes

We work with different materials, so you can pick what fits your priorities. Composite made from wood fibres and recycled plastic gives you a low-maintenance surface backed by premium materials and long warranties. Cedar offers a classic, rot-resistant wood look at a friendlier price. We'll walk you through the trade-offs and which decking materials perform best in our climate — no plastic parts that fail in two seasons.

Deck Repair and Ongoing Maintenance Services

Already have a deck? We provide deck repair, board replacement, railing upgrades, and structural fixes that bring your deck back to a safe, comfortable condition. Our maintenance services — cleaning, sealing, refastening, and inspections — keep every deck lasting longer and looking newer. If your existing deck is past saving, we'll explain why a rebuild makes more sense than another round of patches.

Building Decks Across North Toronto and the GTA

A deck builder in North Toronto serving homeowners from Don Mills to Willowdale and beyond.

Compared to other deck-building companies and decking companies in the area, we focus on craftsmanship over volume. Many deck companies, including the typical deck company, cut corners on framing or use plastic that fails in a few seasons. Our approach is the opposite: structurally sound construction, premium materials, and the kind of finishing touches that turn a basic platform into a real outdoor oasis.

Whether you want a simple new deck off the back door, a wraparound design that creates new outdoor space, or a larger build with rooftop decks and privacy screens, we'll match the right plan to your budget and lifestyle. Contact us today to schedule a visit and start your dream deck.

Frequently Asked Questions

How much does it cost to build a deck in North York?

Deck building costs in the area typically range from $8,000 to $35,000+, depending on size, materials and design complexity. Pressure treated wood is the most affordable option, while composite costs more upfront but requires less maintenance. We provide detailed written quotes so you know exactly what you're paying for.

Do I need a building permit for a deck?

In most municipalities, a building permit is required for decks higher than 24 inches (60 cm) from the ground, or attached to the house. Our team handles the permit process and ensures your deck is code-compliant from start to finish.

What is the best decking material for our climate?

For our freeze-thaw climate, composite decking (Trex, TimberTech) performs best — it won't warp, crack or splinter. Pressure treated cedar is a great natural wood option with good rot resistance. We'll recommend the right material based on your budget, usage and aesthetic goals.

How long does it take to build a deck?

A standard deck in the area takes 1–2 weeks from permit approval to final inspection. Larger builds or those with custom railings and stairs may take 2–4 weeks. We provide a clear timeline before work begins.

What is the difference between composite and wood decking?

Composite is made from wood fibres and recycled plastic — low-maintenance, doesn't splinter and carries long warranties (25+ years). Pressure treated wood costs less upfront but requires sealing, staining and regular maintenance. Both are strong choices depending on your priorities.

How long does a deck last?

A well-built deck can last 15–30+ years depending on materials and maintenance. Composite with proper installation typically lasts 25–30 years. Treated wood lasts 15–20 years with regular maintenance. Our workmanship warranty covers the structural build.

Can you build a deck attached to the house?

Yes. Attached decks are ledger-mounted to the house structure using flashing and hardware designed for our climate conditions. Proper ledger attachment is critical — it must meet Ontario Building Code requirements to ensure safety and prevent moisture infiltration.

What railing options are available for my deck?

We offer aluminum, glass, composite, cable, and wood railing systems. Glass and cable railings maximize views, aluminum is low-maintenance, and wood matches traditional deck aesthetics. All railings are installed to OBC height and load requirements.

Do you handle deck repairs and replacements?

Yes. We assess existing decks for structural integrity, rotted boards, loose connections and safety issues. We can repair specific sections or do a full replacement — whichever makes more financial sense for your situation.

How do I maintain my deck?

Composite decks need only occasional cleaning with soap and water. Wood decks should be cleaned, inspected, and re-sealed or stained every 2–3 years. Keep leaves and debris off the surface, ensure drainage isn't blocked, and check fasteners annually.
