Why these guides, and not a blog

These are the questions we get asked before anyone talks about a deck. Not the ones with the most search traffic behind them, and not one of them is an update on what our crew did last week. Each exists because the same conversation kept happening on site.

They are long on purpose: a short answer to “what does a deck cost in Ottawa” is either a number that is wrong for your yard or a shrug.

Where a guide relies on a rule rather than an opinion, it links to the source rather than asking you to take our word for it. And where we sell the thing being discussed, we say so, rather than pretend to be neutral about materials we install for a living.

Choosing what to build with

Two of the material guides sit one inside the other. Composite, cedar or pressure-treated is the first decision: four families, four very different relationships with maintenance, and four different answers to what an Ottawa winter does to a board over ten years. Read it if you are early enough that the budget is still a range.

If that lands you on composite or PVC, the second guide picks up where it stops. Trex, Fiberon, TimberTech or Azek is a brand-by-brand comparison written from installing all of them, which is a different thing from reading four manufacturers’ own pages. Both guides feed straight into our deck builds, where each material has its own section.

The stone equivalent is interlock versus poured concrete and asphalt. It is the one guide here that is really about physics: a slab is one rigid piece and freeze-thaw only has to find one weak spot in it, while interlock is many pieces that move together on a compacted base. That is the argument behind every patio, walkway and driveway on our Ottawa interlock page.

Once the answer is interlock, Permacon or Techo-Bloc covers the two stone makers we build with: who owns each company, where each makes its pavers, which Ottawa yards show both, and how differently their warranties read.

Planning, permits and money

How much does a deck cost in Ottawa is the one people open first and the one we most want you to read properly. It carries real ranges by material and, more usefully, the list of things that move a price inside those ranges: size, height off the ground, stairs, railing choice, ground conditions and whether a permit is in play.

We still will not quote from it over the phone, and the guide explains why.

How much does a fence cost in Ottawa does the same for fences, with every price credited to the Ottawa guide that published it and worked out for 100 and 200 feet of fence. It also covers gates, taking out the old fence, winter work, and when a neighbour shares the cost of a fence on the line.

The fences themselves, material by material, are on our page for fence installation in Ottawa.

How much does an interlock driveway cost in Ottawa sets the published driveway prices side by side, each read for what it covers, and works a 20x20 driveway out three ways. It also covers the base under the pavers, the City’s access and road cut permits, who pays for the curb, and how wide the Zoning By-law lets a driveway be.

How we build one is on our page for interlock driveways in Ottawa.

When is the best time to build a deck in Ottawa is about the calendar rather than the budget: frozen ground, permit queues, and the fact that everybody in the city wants their deck finished in the same eight weeks. If you are reading this in February you are early, which is the good problem to have.

Do you need a permit for a deck or fence in Ottawa explains what a building permit covers, what a by-law covers, and why a pool enclosure is its own category. It stays general about thresholds on purpose and points at the City for the current numbers. We prepare the drawings and file the applications as part of the build either way.

When the fence is already up

Fence repair in Ottawa starts at the posts, because that is where an Ottawa winter does its damage. It covers what can be fixed one post at a time, when a rebuild has to meet today’s Fence By-law even where the old fence did not, what a pool enclosure needs before the pool opens, and who pays when the fence sits on the line with a neighbour.

Where the answer depends on your address

None of these guides can tell you what your particular lot needs, because the thing that changes across Ottawa is not the price list. It is the servicing, the ground, the lot size and the approvals: a septic bed deciding where footings go in Greely or Navan, conservation authority land along the Jock, Carp and Rideau rivers, a heritage permit before any exterior change in Rockcliffe Park.

That is what the service areas pages are for. Read the guide for the decision, then read your area’s page for what is different where you live. And if your deck is standing but tired, deck repair is a better starting point than any of these, because the first question there is whether the frame is worth keeping.
