Frequently Asked Questions

Common questions about Deck services in Markham.

How much does it cost to build a deck in Markham?

Deck building costs in Markham 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 decking 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 Markham?

In most municipalities including Markham, 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 Markham's climate?

For Markham's 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 Markham takes 1–2 weeks from permit approval to final inspection. Larger, multi-level decks 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 pressure-treated wood decking?

Composite decking is made from wood fibres and recycled plastic — it's 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 in Markham can last 15–30+ years depending on materials and maintenance. Composite decks with proper installation typically last 25–30 years. Pressure-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 Markham's 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 in Markham 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 new 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.
