Decks in Ottawa: cost, permits and when the ground lets you build.

We do both. A lot of Ottawa decks that look finished are actually repairable, because the freeze-thaw cycle tends to damage a deck from the top down: the boards grey, split and cup first, fasteners work loose as the wood expands and contracts, and the framing and footings underneath are usually the last part to fail. If the structure is still sound, replacing the damaged boards, re-securing the framing and hardware and re-staining the surface can give you back a deck you want to use without the cost of a full rebuild. The honest exception is a deck that has shifted because its footings were never set below the frost line, which is a structural problem rather than a surface one, and no amount of new decking will hold it still. We look at the framing and the footings before we quote anything, and we will tell you plainly which of those two situations you are in rather than selling you the bigger job.

It comes down to what the framing and the footings are doing, not how the surface looks. Boards are the cheapest part of a deck to change, so grey, splintered or cupped decking on its own is rarely a reason to tear the whole thing out. The questions that actually decide it are whether the joists and beams are still sound or have taken on water and gone soft, whether the posts and footings are still sitting where they were built, and whether the deck was framed to carry what you want to put on it now. If the structure is good, repair is almost always the better value. If the frame is rotting or the footings have heaved through a few Ottawa winters, repairs become money spent on something that will move again, and rebuilding is the cheaper answer over the life of the deck. We assess it in person before quoting, and because every build we design goes through 3D and AutoCAD first, you can see a rebuild costed properly against a repair and decide with real numbers in front of you.

They all have a place, and it comes down to your budget and how much upkeep you want to do. Pressure-treated wood is the most affordable to start and needs regular staining, while western red cedar is a natural wood that ages gracefully with some care. Composite boards from Trex, Fiberon and TimberTech resist rot and fading with little maintenance, and PVC from Azek and Clubhouse is fully synthetic and the lightest on upkeep. All four hold up to Ottawa's freeze-thaw winters when the framing and footings are built properly, and composite and PVC boards typically carry their own manufacturer warranties on fade and staining, on top of our written workmanship warranty on the build itself. We design your deck in 3D and AutoCAD first, so you can compare the look and an honest price across every material before choosing.

Pressure-treated and cedar are real wood, so plan on cleaning and re-staining from time to time, while composite and PVC just need an occasional wash. Real wood generally wants attention every couple of years to keep its colour and stop it from greying, while composite and PVC boards are built to resist that fading without any sealing or painting at all. Our decks are built for Ottawa's freeze-thaw cycles, harsh winters and humid summers, starting with proper framing and footings set below the frost line so the structure does not move with the seasons. Composite and PVC boards resist moisture, rot and fading, which helps them handle the swing from icy Januarys to muggy Julys, and every project is backed by a written workmanship warranty regardless of the material you choose. We build composite decks in Trex, Fiberon and TimberTech, and PVC in Azek and Clubhouse, all chosen for how they perform through that freeze-thaw swing.

Many decks do, depending on their height, size and how they attach to the house, though some smaller ground-level builds may not. Because those thresholds are set by the City of Ottawa and can change, we always confirm the current requirements for your specific plan rather than relying on what a neighbour built a few years ago. If your project needs a permit, we handle the drawings, the application and the bylaw setbacks as part of the build, and because every deck is already designed in 3D and AutoCAD before we start, those same drawings are what the permit application needs. If it does not need one, we tell you plainly so you are not paying for paperwork you do not need. Whether you are building in Kanata, Barrhaven, Orleans, Nepean, Stittsville, Gloucester or elsewhere in Ottawa, the same City of Ottawa process applies, so we walk you through it either way.

Timelines depend on the size, materials, design and whether the project needs a City of Ottawa permit, so we give you a realistic schedule once your plan is set and any permit paperwork is accounted for. Matching your home is exactly why we design every project in 3D and AutoCAD before a single board is cut, so you approve the exact colour, layout, railings and stairs that suit your house and yard, rather than guessing from a sample board. Whether you are in Kanata, Barrhaven, Orleans, Nepean, Stittsville, Gloucester or elsewhere in Ottawa, you see the finished look before we start, and the build is backed by a written workmanship warranty with the terms set out in your signed project agreement. We build in composite, cedar, pressure-treated and PVC, and each material affects the schedule a little differently, which is another reason we set the timeline once your material and design are locked in rather than upfront.

Yes to both. We offer a written workmanship warranty, with the exact duration and terms laid out in your signed project agreement, and brands like Trex, Fiberon, TimberTech, Azek and Clubhouse carry their own manufacturer warranties on the boards themselves, which is worth reading alongside the workmanship warranty on the build. Financing is available through our third-party partner iFinance if it helps spread the cost of a larger project, though any figure we mention in conversation is illustrative only and not an offer of credit. As a family-owned, licensed and insured Ottawa company, we are happy to walk you through both the warranty terms and the financing option in detail when we meet for your consultation. We serve Kanata, Barrhaven, Orleans, Nepean, Stittsville, Gloucester and the wider Ottawa area, and every deck is designed in 3D and AutoCAD first, so the warranty and financing conversation happens once you already know exactly what you are building.

A raised deck suits sloped or uneven yards and gives you a level outdoor room off the house, while a ground-level interlock patio in Techo-Bloc or Permacon stone works well on flatter ground and needs no framing or footings below the frost line. A deck also gives you a walkout at door height without building up the yard, while interlock reads as an extension of the ground itself and can wrap around a pool or tie a driveway, walkway and patio into one design. Some yards genuinely suit a mix of both, a deck off the house stepping down to an interlock patio further back. We design either option in 3D and AutoCAD first so you can see it before deciding, and we cover the full freeze-thaw and cost comparison in our separate interlock guide.

Size, material tier, structure and permits drive most of the cost. A larger footprint, a second level, built-in stairs, custom railings and any lighting or pergola add-ons all add labour and material beyond a simple ground-level platform, and a deck that needs a City of Ottawa permit carries the added time of preparing drawings and an application. Material tier matters too: pressure-treated is the most affordable per square foot, cedar sits above it, and composite or PVC cost the most up front in exchange for close to no maintenance. For context, industry cost guides such as RenoQuotes' 2026 Canada deck-cost guide put installed composite or PVC decking at roughly $100 to $130 per square foot and pressure-treated at roughly $35 to $60, though those are national industry ranges, not an Ottawa Decking Solutions quote. We do not publish a fixed price list because every yard, base condition and design is different; we design your deck in 3D and AutoCAD first so you see the exact layout and get one honest, project-specific price before you commit, and financing is available through our third-party partner iFinance if it helps spread the cost.

Published 2026 Canadian ranges put installed composite and PVC decking at roughly $100 to $130 per square foot, versus about $60 to $90 for cedar and $35 to $60 for pressure-treated. Those are national industry ranges, not an Ottawa Decking Solutions quote. Because size, structure, railings, lighting and whether the City of Ottawa needs a permit all move the number, we do not publish a fixed price list. We design your deck in 3D and AutoCAD first, so you see the exact layout and get one honest, project-specific price, and financing is available through our third-party partner iFinance if it helps spread the cost.

PVC asks the least of you. It is all plastic with no wood content, so it is the lightest, most moisture-proof and most fade-resistant of the four, followed closely by composite in Trex, Fiberon and TimberTech, which needs no sanding, sealing or staining, just a wash a couple of times a year, with the colour staying even through freeze-thaw. Cedar and pressure-treated are real wood, so they need cleaning and re-oiling or re-staining every couple of seasons to hold their colour through Ottawa's wet, dry and freezing swings. Whichever you choose, every deck is built to handle the freeze-thaw and backed by a written workmanship warranty.
