Custom Decks Built for Ottawa Backyards
Ottawa decks live through freeze-thaw cycles, heavy snow loads and humid summers, so how a deck is framed matters as much as how it looks. We build every deck on helical piles driven below the frost line, frame with 6″ x 6″ posts and triple-stacked 2x8 beams, and fasten with Simpson Strong-Tie hardware — the reason our decks stay level and quiet years after the build.
You see the design before we build it. Every project starts with an on-site measure and a CAD rendering, so the layout, stair placement, railing style and material colour are settled on paper first. Add aluminum or glass railings, a pergola or a gazebo and we detail it all in the same drawing and the same quote.
Ottawa's Only Trex Builder
We are Ottawa's only Trex builder, and as a Trex Pro-Platinum contractor we hold the highest level of certification available — a mark reserved for installers with proven expertise, quality craftsmanship and a consistent track record of exceptional Trex composite deck builds.
Expert Deck Design
At Fence Masters Ottawa, we focus on ensuring your deck not only complements your home aesthetically but also enhances your outdoor living experience. Our process is collaborative and detail-oriented, ensuring your vision becomes a reality.
To help you visualize your dream deck, we provide detailed CAD drawings — renderings that let you see and tweak the design before construction begins, ensuring every detail is exactly to your liking.
Decking Materials We Build With
Whether you prefer natural wood or virtually maintenance-free composite, we build with materials chosen for beauty, durability and performance in the Canadian climate.
Pressure Treated Spruce (MicroPro® Sienna)
CSA-certified wood preservation built for the Canadian climate. A micronized copper azole (MCA) formulation shields against fungal decay and termite damage for a durable, dependable deck.
Western Red Cedar
Premium 1st Grade lumber sourced from British Columbia with a 15–25 year life expectancy. Rich, vibrant hues that can be left natural or coated for a lasting, warm-underfoot finish.
Trex Composite Decking
Ottawa's premier low-maintenance decking. Hidden fasteners, a 25+ year lifespan, and a limited lifetime material warranty — available in an extensive range of colours and finishes.

Superior Deck Construction
The excellence of our deck construction is unparalleled. We build with an unwavering commitment to durability and quality — cutting corners is never a practice at Fence Masters Ottawa.
- Substantial 6″ x 6″ posts for a sturdy, reliable base
- Triple-stacked 2x8 beams for a robust, enduring structure
- Simpson Strong-Tie fasteners throughout for strength and reliability
- End coat treatment on every framing cut to preserve timber integrity
- All exterior boards fully screwed down — no squeaks, no loosening
Helical Piles: The Foundation of Stability
Resembling large screws, helical piles are deeply embedded into the earth using specialized machinery. A helix plate at the base ensures firm anchorage.
Unlike traditional concrete foundations, helical piles extend below the frost line — resistant to soil movement and delivering exceptional stability, even on challenging soil or uneven terrain.

What Ottawa Deck Clients Say
4.9 average across 220+ reviews.
We had a great team doing our custom deck. Wife is disabled and mobility is an issue. The team had my wife check out the deck and steps to ensure she would be able to navigate. For the front they had her show how she gets out and placed the railing well within her reach. So nice that she can navigate out the doors with minimal assistance!

What Determines Your Deck Cost
We quote from a drawing, not a rule of thumb. These are the factors that move the number most on an Ottawa deck build.
Size and height
Square footage drives material volume, and a raised deck needs taller posts, more framing and guard railings that a ground-level platform does not.
Decking material
Pressure-treated spruce is the most budget-friendly option, Western Red Cedar sits in the middle, and Trex composite costs more up front but removes staining from your maintenance list.
Foundation
Helical piles cost more than surface blocks, but in Ottawa's freeze-thaw ground they are what keeps a deck level for decades.
Railings and extras
Aluminum or glass railings, lighting, privacy screens, benches, pergolas and multi-level layouts all add to the build.
Site access and grade
Tight side-yard access, sloped lots and removal of an old deck add labour time to the project.

Ottawa Deck Building FAQs
How much does a deck cost in Ottawa?
Every deck is priced from its own drawing — size, height, material, foundation and railing choices move the number more than anything else. We measure on site, produce a CAD design, and give you an itemized quote before any work is booked, so you are never comparing guesses.
How long does it take to build a deck?
Most residential decks are built in one to two weeks on site once materials arrive. Design, permitting and scheduling come first, so plan for a few weeks between your estimate and your build date — spring and early summer book up fastest in Ottawa.
Do I need a permit for a deck in Ottawa?
The City of Ottawa requires a building permit for decks above a set height and for any deck attached to the house. We tell you exactly what your project needs during design and handle the drawings required for the application.
Composite or wood — which is better for Ottawa winters?
Both work when they are framed correctly. Cedar and pressure-treated wood cost less up front and need periodic cleaning and staining. Trex composite costs more initially, resists fading and staining, and needs only soap and water — which is why most of our repeat clients choose it.
Can you build on a sloped or uneven yard?
Yes. Helical piles screw below the frost line and anchor firmly even on challenging grades, so we can build level, multi-level or stepped decks on lots where concrete footings would be difficult.
Which areas around Ottawa do you serve?
We build decks across Ottawa and the surrounding communities including Kanata, Barrhaven, Nepean, Orleans, Stittsville and Manotick.
