Muskoka deck builder: composite decks for cottages and lakefront homes

Updated October 26, 2026 · By Mike, Simcoe Decks

Simcoe Decks designs and builds composite decks for cottages and lakefront homes across Muskoka, from Huntsville and Bracebridge to Gravenhurst, Muskoka Lakes, Lake of Bays and the Township of Georgian Bay. We build on helical piles and match the frame to the board, and by a dock, pool or hot tub we look at Voyage first, the Deckorators board warranted in water and ground contact.

Where: Huntsville, Bracebridge, Gravenhurst, Muskoka Lakes, Lake of Bays and the Township of Georgian Bay. We're based in Barrie.

What we build: Composite decks, stairs and landings, frameless and framed glass railings, aluminum picket railings, lighting and louvered pergolas

Boards: Deckorators Venture, Summit and Voyage. By a dock, pool or hot tub, Voyage first.

Frame: Pressure-treated (today's fast-growth lumber) or Fortress Evolution steel, matched to the board

Footings: Helical piles turned in to bear below the frost line, about 4 ft down

Warranties: Voyage boards: 50-year structural. Fortress steel frame: 25-year. Our workmanship: 3 years, in writing.

Permits: Set by each town or township, and they differ. Waterfront lots often need a planning approval too. We plan the building permit as part of the build.

First step: Tell us where the cottage is and what you're planning. We prepare a model you can explore, then visit the lot.

Why does a Muskoka deck need its own plan?

There's no perfect deck board, and no perfect frame. Different lots call for different things, and a cottage lot asks more of a deck than most city backyards.

Water. A dock, a hot tub or a deck a few steps from the shore stays wet for days at a time.
Shade and damp. Under the pines, boards dry slowly and the frame underneath stays damp.
Rock and slope. Many Muskoka decks are built out over a hill, a walkout or bare rock, so they stand tall and the underside is on show from the shoreline.
Weekends. If you only get up on weekends, the last thing you want is to spend them sanding and staining.

So we walk the lot before we pick anything: where the sun lands, what stays wet, how the deck meets the slope and what it's for.

Which deck boards hold up best at the lake?

We install three of the five Deckorators lines, Venture, Summit and Voyage, and we lean to Summit and Voyage: the strength of a composite with no organic material in it. Here's how we match a board to a Muskoka lot:

Dock, pool or hot tub: Voyage first. It's mineral-based, shrugs off moisture, sun and microbes, and it's warranted in water and ground contact.
Shade and damp: Summit or Voyage. Both are mineral-based, with no wood in the core.
Full sun on an open lake: Summit or Voyage, in a lighter colour. Voyage has low heat retention compared to other composite boards.
Budget first: Venture, a capped composite.

Voyage carries a 50-year structural warranty, and Deckorators rates its surface traction 34% greater than other leading composite brands. We're a Deckorators Certified Elite builder, so a warranty claim goes through us, not a call centre.

What goes under a cottage deck?

The frame and the footings are the part you'll never see again, so they get the most thought.

Footings. Our helical piles are steel piles turned in to bear below the frost line, about 4 ft down. There's no digging and no concrete to cure, and they can go in close to gardens, existing decks and patios with very little disruption to the lot. Each pile is installed to torque. Much of Muskoka sits on the Canadian Shield, and on that bedrock we sometimes attach the footings to the rock instead. The bedrock runs below the frost line and doesn't move.

Frame. We match the frame to the board. Under Venture, pressure-treated wood is the lower-price choice, but today's pressure-treated is fast-growth lumber, grown to be harvested again, and it can twist and shrink as it dries. Under Summit, Fortress steel is worth a look; under Voyage, steel definitely. Steel can't rot, twist or shrink, every beam is checked against Fortress's own sealed span tables, and the frame carries a 25-year warranty.

On a slope, steel earns its keep twice. It spans further, so fewer posts land on the hill, and the black frame looks finished from the shoreline, where the underside of a tall deck is on show. We held the first Fortress Evolution steel framing masterclass in Canada with Fortress.

Which railing keeps the lake in view?

We pick between three railings: frameless glass, framed glass and aluminum picket. The choice turns on the view, the wind, and who's using the deck. Where the deck is built around the view, glass frames the water instead of blocking it.

On the Huntsville rebuild, the old railing was bulky, interrupted the view from the cottage to the water, and was tied into the stone columns. We took it apart carefully, repaired the stone, and fitted a slim glass railing so the lake stays in view whether you're sitting or standing. Subtle In-Lite accent lighting marks the paths, the transitions and the edge after dark without overwhelming the view.

What have we built in Huntsville?

The full story is in our Huntsville lakefront deck case study. The short version:

The cottage had a great layout and a tired wood deck. Boards had gone soft, and weekends were going to sanding and staining.
We resurfaced it in Deckorators Voyage Khaya, reframing where the structure needed it.
The orientation meant standard 20-foot boards would leave seams across the view, so we had the manufacturer custom-run 24-foot boards.
Hidden Camo fasteners leave no screws in the surface.
The cottage is used mostly in summer, so the work was timed around the season.

We've built other decks in Huntsville and in Bracebridge too.

Do you need a permit for a deck in Muskoka?

Usually, and the rules depend on where the cottage is. Each of Muskoka's six area municipalities issues its own building permits, and on the water there's often a planning approval as well. Here's what each one publishes for decks:

Huntsville: a permit for all decks, with two listed exceptions: a deck no more than 24 inches above the ground that doesn't support a roof, and one no larger than 10 m² that isn't attached to another building. Any development on a waterfront property needs a Community Planning Permit, and the shoreline buffer runs at least 15 metres back from the water.
Bracebridge: a permit for a deck more than 24 inches above the ground. Lower decks without a roof don't need one.
Gravenhurst: a permit for a deck over 10 m² (108 sq ft) or attached to a building. The site plan shows the 20 m (about 65 ft) shoreline setback where it applies.
Muskoka Lakes: decks need a permit, and site plan approval may be required on a waterfront lot. The township can apply site plan control within 120 metres of an inland lake.
Lake of Bays: a permit for freestanding decks of 10 m² and up, at any height. Building or making changes on waterfront property needs a Community Planning Permit. The list doesn't mention attached decks, so ask the township.
Township of Georgian Bay: the planning department issues a Zoning Certificate before any building permit. Shoreline or in-water work can also need approval from the province, the Trent-Severn Waterway or Fisheries and Oceans.

Your lot's zoning can add more, so treat this as a starting point. We plan the building permit as part of the build, not as your homework.

Can a louvered pergola work at the cottage?

Yes. An Eclipse louvered pergola is a motorized aluminum roof over part of the deck. The louvers tilt to control sun, airflow and rain, and when they're fully closed they lock together into a watertight cover. The powder-coated finish never needs repainting. A roof can change the permit, too: Huntsville's and Bracebridge's low-deck exemptions don't cover a deck that supports one. See the louvered pergola page for sizes and options.

How do we plan a cottage deck when you're not there all week?

You can start from the city. Tell us where the cottage is and what you want from the deck: no drawings, photos, exact measurements or settled budget needed. Our team reviews your brief and prepares a model, and you explore layout and material choices with preliminary estimates.

Then we visit the lot, free and normally for about an hour, to confirm measurements, access and site conditions. After that site review we prepare your proposal, with the materials, inclusions, options, pricing and terms, and you decide at your pace. How we work has the full path.

Which Muskoka towns do we build in?

All six of the District's municipalities: Huntsville, Bracebridge, Gravenhurst, Muskoka Lakes (including Port Carling and Bala), Lake of Bays and the Township of Georgian Bay. Closer to home, see our Barrie deck builder page and our Collingwood and Blue Mountains page.

What do Muskoka cottage owners ask us?

Do you build decks in Muskoka?

Yes. Simcoe Decks builds composite decks for cottages and homes across Muskoka, including Huntsville, Bracebridge, Gravenhurst, Muskoka Lakes, Lake of Bays and the Township of Georgian Bay. We're based in Barrie, and we've built lakefront decks in Huntsville.

What is the best deck board for a lakefront cottage?

There's no perfect deck board. By a dock, pool or hot tub we look at Voyage first: it's mineral-based and warranted in water and ground contact. In shade and damp we pick Summit or Voyage, in full sun a lighter colour, and where budget comes first, Venture.

Can you build a deck on a sloped or rocky lot?

Yes. Sloped sites and rocky terrain are common in Muskoka, and they're where steel framing shines: it spans further, so fewer posts land on the slope. On Canadian Shield bedrock we can attach the footings to the rock, which runs below the frost line and doesn't move. We decide the footings for your lot when we walk it.

Do I need a permit for a cottage deck in Muskoka?

Usually. Each of Muskoka's six municipalities sets its own rule, and waterfront lots often need a planning approval as well. Huntsville, for example, requires a permit for all decks except two cases it lists: a deck no more than 24 inches up with no roof, and a small freestanding one. We plan the building permit as part of the build, not as your homework.

Do I need to be at the cottage for the design?

Not to start. You can share your ideas and explore the model we prepare, with preliminary estimates, from wherever you are. We visit the lot to confirm measurements, access and site conditions before we prepare your proposal.
