Composite and steel-frame decks for Collingwood and Blue Mountains homes
See what you are getting. Understand what it costs. Know how it will be built.
Collingwood and the Blue Mountains are not a starter-deck market. Wind, snow load, slope, and four-season use change the structure. A small wood platform off the back door will not hold up the same way here as it does on a sheltered lot.
Simcoe Decks designs and builds premium outdoor living spaces across Southern Ontario. Owner Michael Scott runs the work. We use composite decking, Fortress Evolution steel framing, helical piles, and In-Lite lighting so the space you approve is the space that gets built.
If you want a number, a material list, and a sequence — not a vague “it depends” — book a Deck Planning & Budget Review. Call (705) 300-2903.

These are finished jobs on this side of Georgian Bay. Costs below are the figures published in each case study. They are approximate. They are not a quote for your lot.
A new-subdivision backyard, Collingwood — about $150,000 (deck portion)
A new subdivision lot. Retired homeowners relocating from the city. Blank backyard, conservation-authority overlay, tight access.
The deck is Deckorators Voyage in Costa on Fortress Evolution steel, set on helical piles. Deckorators ALX railing. A full In-Lite package. A sunken hot tub with a custom aluminum privacy wall. BBQ zone and gas fire table. A covered entertaining area with motorized zip screens around the perimeter.
The $150,000 figure is the deck portion of a larger backyard that also includes a pool. Permits had to wait on final grading, then conservation review, then the township. That sequence is the job in a new Collingwood subdivision. Read the Collingwood backyard transformation.
A rebuilt deck with a timber pavilion, Town of The Blue Mountains — about $70,000 (deck and lighting)
A builder-grade wood deck that nobody used. The homeowners wanted a daily outdoor room that also worked when family visited.
We rebuilt in Deckorators Voyage — Tundra field, Sierra accents — on Fortress Evolution steel. Custom powder-coated privacy wall under a timber pavilion. Complete In-Lite system with dimmable zones.
The $70,000 covers the deck, the privacy feature, and lighting. Pool, landscape, and pavilion structure were by trade partners, quoted separately. See the pavilion deck.
A two-level, four-season build, Town of The Blue Mountains — $400,000+
Two patio doors. No landing. No stairs. The first request was a small hot-tub platform.
The finished build is a two-level composite deck on helical piles and Fortress Evolution steel. Voyage Costa with Dark Slate vertical accents. Frameless glass. An enclosed room with motorized guillotine windows and integrated heat. In-Lite throughout. A minor variance was required for the footprint. Construction ran through the winter of 2025.
$400,000+ is not a deck-board number. It is a four-season outdoor living environment: structure, glazing, motorization, heat, lighting, and the planning that made the variance possible. Walk through it: composite decking in the Blue Mountains.
Nearby, a Meaford steel-frame rebuild came in at about $75,000 — Voyage Costa, Fortress steel, helical piles, vertical cable rail, post-cap lighting — on a mature, landscaped lot we were asked not to disturb. More completed work is on the projects page.
What a Collingwood deck actually costs
Two published numbers sit on this site. They describe different things. Mixing them up is how homeowners get surprised.
The contact page gives a starting point of about $100–$150 per square foot for a custom composite deck. That is a planning floor for a typical custom build, not a Collingwood outdoor-living budget.
The 2026 cost guide prices core deck structure only, on a typical 120–300 sq ft footprint. Stairs, oversized landings, lighting, privacy, skirting, and covered structures are extra. Height moves the number. Those core ranges:
- Foundation (Venture): Helical piles + pressure-treated framing, composite, aluminum picket rail - $15,000–$25,000
- Elevated (Summit): Larger spans, fewer posts; lighting, water management, or finished undersides often appear here - $18,000–$35,000
- Pinnacle (Voyage): Full steel framing, premium composite, maintenance-free rail including frameless or semi-frameless glass - $20,000–$45,000
Pinnacle is the level that matches how we build most of the Collingwood and Blue Mountains work above: steel frame, premium Voyage boards, glass or architectural rail, and room for pergolas and motorized screens.
Those core ranges are not what the case studies cost. A 200 sq ft Pinnacle deck at the top of the 2026 band is still a core structure. The pavilion deck at $70,000 already includes privacy and a full lighting package. Meaford at $75,000 is a steel rebuild with cable rail and lighting, built around existing gardens. The Collingwood backyard at $150,000 is a zoned outdoor room with cover, zip screens, hot tub integration, and lighting. The four-season build at $400,000+ has two levels, glazing and heat.
A sheltered Barrie lot and an exposed Collingwood or Blue Mountains lot are not the same job. Slope, access, soil, wind, and snow load change the structure and the labour. National “average cost per square foot” pages do not account for that.
How to read this if you live here: if you want a small, straightforward composite deck, the 2026 Foundation to Pinnacle bands are the honest core range. If you want the kind of space in the local case studies — steel, helical piles, lighting, cover, privacy, or a four-season room — plan from the $70,000–$150,000 work we have already built on this side of the bay, and treat $400,000+ as what happens when the program becomes a full outdoor living environment. The formal quote is itemized. You will see which line is structure, which line is extras, and which line is site condition.
Stairs are a frequent surprise. They are not a few extra boards. Each rise is its own small build — stringers, treads, rail, often a landing and a footing. We wrote that out in How much do deck stairs cost?.
How it is built
The part you never see is the part that fails first on a wood deck.
Helical piles. We start in the ground. Helical piles resist frost heave and limit excavation. That matters on a sloped Blue Mountains lot, in variable soil, and on a Meaford property where the gardens had to stay. They are the foundation under the Collingwood backyard, the pavilion deck, the four-season build, and the Meaford job.
Fortress Evolution steel framing. Wood framing moves. It shrinks, twists, and eventually rots in Ontario freeze–thaw. Steel stays dimensionally stable, so the surface you paid for stays flat. We have installed about 100 steel-frame structures in the last six years, including the first Fortress Evolution steel framing masterclass in Canada. Full steel is the Pinnacle spec. It is also what sits under the Collingwood backyard, the pavilion deck, the four-season build, and the Meaford job. Read why we frame in Fortress steel.
Deckorators Voyage composite. Mineral-based boards. They do not need staining or sealing. They do not splinter. Manufacturer fade and structural warranties on composite typically run 25–50 years; wood mills do not match that. We are a Deckorators Certified Elite builder. Voyage Costa was the walking surface in Collingwood and on the four-season build. The pavilion deck used Tundra with Sierra accents. Composite vs wood is the longer comparison. We do not install finished pressure-treated decking.
Lighting. In-Lite is specified as a system, not a last-minute post cap. Stairs, transitions, and gathering zones get light so the deck works after dark. That package is in every case study on this page.
Cover, screens, and climate control. An Eclipse louvered pergola is the add-on when you want shade, rain protection, and airflow on demand. 6063-T6 aluminum, motorized louvers, smartphone and remote control, optional LED perimeter lighting. Structural warranty on the pergola is 10 years; motors are 2. Motorized zip screens, sliding glass, guillotine windows, and bi-fold doors turn a deck into a room you can still open. The Collingwood backyard used zip screens on a covered entertaining area. The four-season build used motorized guillotine windows and heat. Heaters and screens as a system are covered in extending the season.
Permits. We plan them as part of the build, not as your homework. On the Collingwood backyard job the property sat under conservation-authority oversight in a new subdivision: final grading, then conservation review, then township permits. On the four-season build the footprint needed a minor variance — drawings, municipal coordination, and time. Deck stairs attached to a home, or over a certain height, commonly need a permit in Collingwood, the Blue Mountains, and across Simcoe and Grey County. Permit cost and inspections belong in the project plan from the start.

How we work with you
From the contact process:
1. Share details. You reach out. We follow up by email for photos of the space, your ideas, and timing.
2. Discovery call. We go through the site, how you want to use it, and budgetary options.
3. On-site consult. We walk the lot, talk design, and match materials to the property — exposure, access, and how the house actually sits.
4. Formal quote. A design concept, a timeline, and transparent pricing. You should know what you are getting, what it costs, and how it will be built before anyone mobilizes.
5. Project planning. Once approved: timelines, material selections, logistics. We handle that so the site is ready before we break ground.
6. Build. Organized crew, clear communication, the spec you signed.
We do not start with “get a quote.” We start with a Deck Planning & Budget Review. Bring photos. Bring a rough size. Bring the number you do not want to exceed. That is enough to have an honest conversation.
Where we build
We build for homeowners in Collingwood, the Town of The Blue Mountains, Meaford, and surrounding Grey County communities, as well as Barrie and the rest of Simcoe County. If you are nearby and unsure, ask. The contact page is the short version: Barrie, the Blue Mountains, and surrounding communities.
Huntsville and Muskoka lakefront work is on the books too — a Voyage Khaya rebuild on an existing cottage structure — if your property sits further north.
FAQ
How much should I budget for a Collingwood or Blue Mountains deck?
The contact-page starting point is about $100–$150 per square foot for a custom composite deck. The 2026 guide’s Foundation / Elevated / Pinnacle bands ($15,000–$45,000) are core structure only on 120–300 sq ft. Local finished jobs on this page landed at about $70,000, $75,000, $150,000, and $400,000+. Collingwood and Blue Mountains work is typically well above a small starter deck once steel, helical piles, stairs, lighting, cover, or glass are in the program. Use the case studies as the reality check. Use the 2026 ranges as the core-structure floor. The quote is itemized.
Why composite instead of wood?
Wood needs staining and sealing. It splinters, moves, and breaks down under freeze–thaw. Composite does not rot, crack, or splinter the same way, and it does not need an annual maintenance weekend. A soap-and-water wash once or twice a year is typically enough. We specify mineral-based Voyage because it holds dimension in Ontario temperature swings. Longer version: composite vs wood.
Why steel framing instead of wood framing?
If the boards are meant to last decades, the frame underneath should not be the weak link. Pressure-treated lumber moves with moisture. Fortress Evolution steel stays straighter, which matters on elevated decks, glass rail, hot tubs, and covered structures. That is why Pinnacle is full steel, and why the Collingwood backyard, the pavilion deck, the four-season build, and the Meaford job are steel-framed. Fortress Evolution steel framing.
Do you handle permits?
Yes — they are part of planning, not a separate errand we hand back to you. Our Collingwood backyard job required conservation-authority sequencing before township permits. The four-season build required a minor variance. Stairs and attached decks commonly need permits in this area. Inspections belong in the same plan.
When is the best time of year to build?
We build when the job needs to be built. The four-season build ran through the winter of 2025, one of the heavier snow years in recent memory. Planning still matters: materials, variances, and conservation review all take calendar time. If you want the space for a specific season, start the Deck Planning & Budget Review before you need it on site.
How long does a project take?
There is no honest single number. A rebuild on an existing footprint is a different schedule than a two-level, four-season room that needs a variance. The pavilion deck had a hard family-visit deadline and was staged with other trades to hit it. The formal quote includes a timeline. That is the number to plan around.
What about warranties?
Composite manufacturers typically warranty fade and structure for 25–50 years. Eclipse pergolas carry a 10-year structural warranty and a 2-year motor warranty. We will walk the material warranties that apply to your spec in the quote. The existing page promise is itemized pricing and a real warranty — not a slogan on a flyer.
Can I add a louvered pergola later?
You can. It is cleaner if we design the deck and the pergola as one structure — load path, posts, screens, and lighting. Eclipse louvered pergolas.
