A-202.1 Why MKC
Why choose MKC for decks
A deck carries people, furniture and snow, so the work that counts is the part you never see. That means footings below the frost line, beams and joists sized for the span, and guards that meet the Ontario Building Code. Our engineering department works out the structure and prepares the permit drawings, and the same company builds it. Then you choose the surface: composite from TimberTech, Trex or TIVADEK, or pressure-treated or cedar with Benjamin Moore Arborcoat stain.
Glass railings, engineered in-house
Glass guards must carry the same loads the Ontario Building Code sets for any guard. Our engineers specify the glass, posts or base shoe and anchors, and because it’s custom glass work, your railing comes with a free engineering letter for the permit file.

A-202.3 Budget & schedule
What affects
the price
Every estimate is built from your measurements and choices. These are the things that move the number most.
On-site work for a typical deck is measured in days to a few weeks, depending on size, levels and railing type. The permit, when you need one, comes first, and some composite colours or custom glass can add lead time.
Every project is different, so your estimate comes with its own written schedule, and we aim to beat the usual industry timeline on every job.
- 01Height above ground
Higher decks need taller posts, bracing and guards, and in Toronto any deck over 60 cm above ground needs a permit.
- 02Decking material
Composite boards cost more upfront than pressure-treated wood, but they don’t need staining.
- 03Railing type
Glass, aluminum and wood railings differ in price per linear foot, and glass adds engineering and hardware.
- 04Size & shape
Square footage, levels, stairs, angles and picture-frame borders all add framing and cutting time.
- 05Existing structure
Tearing out an old deck, or reusing a sound frame spaced for the new boards, changes the scope.

A-202.4 Questions
Questions about decks
Don’t see your question? Call (647) 637-6052 or ask in your estimate request.
Do I need a permit for my deck?
That depends on where you live. In Toronto, a deck needs a building permit when any part is more than 60 cm above the ground, it has a roof, or it serves a required exit. Bradford West Gwillimbury also requires one for decks attached to the house or larger than 10 m², whatever the height. Zoning rules apply either way. We confirm which rules apply to your address, then prepare the drawings and file the permit application ourselves.
How high does the railing have to be?
Under the Ontario Building Code, a deck 600 mm (24 in.) or more above the ground needs a guard. On a house deck, the guard must be at least 900 mm (35 in.) high up to about 1.8 m above the ground, and 1 070 mm (42 in.) above that. Openings can’t exceed 100 mm (4 in.), and nothing between 100 mm and 900 mm up can make it easy to climb. We design every railing to those numbers.
Can you put composite boards on our existing deck frame?
Sometimes. TimberTech, for example, calls for joists no more than 16 inches apart on centre for residential decks, and 12 inches when the boards run diagonally, and many older wood frames are spaced wider. We open up the deck, check the joists, beams and footings for rot and spacing, and tell you whether the frame can carry composite or should be rebuilt.
Composite or wood: what’s the real difference?
Upfront cost and upkeep. Pressure-treated wood costs less to build and takes stain well, but it needs periodic cleaning and restaining to hold its colour. Composite from TimberTech, Trex or TIVADEK costs more at the start and needs only washing. Cedar is another option if you want natural wood. Ask us to quote both and we’ll show you the difference line by line.
Can we finance a new deck?
Yes, on eligible projects through Financeit. Financeit sets the approval, rates and terms, and you can apply once you have our estimate. Financing lets you build the full design now, glass railings and stairs included, instead of splitting the work over two seasons. We can walk you through the application when we review the quote with you.
