Stittsville is not one place, and that matters more for hardscaping than it does for almost any other trade. A patio in the village core and a patio in a subdivision finished five years ago look identical in a photograph and are built quite differently underneath.
The reason is history. Stittsville grew around Jackson Stitt’s mills from 1818, was rebuilt around the railway after fire destroyed the original settlement in 1870, saw its first subdivision in 1901, then spread outward in three distinct waves. Each wave left different ground behind.
The three Stittsvilles
The village core. The streets around Main Street, Abbott and Manchester carry the oldest housing in the community. This ground has been built on, dug up and settled for well over a century. It is generally stable, which is the good news, but it also hides things — old service runs, previous walkways, and fill from work nobody documented.
The post-war lots. The first subdivisions after the Second World War went onto large lots, because every house needed room for a well and a septic bed. The village was not connected to municipal water and sewer until the late 1970s. Those big yards are a gift for hardscaping — there is genuinely space to work with — but a decommissioned septic bed is not the same ground as undisturbed soil, and we want to know where it was before deciding where a patio goes.
The new subdivisions. Stittsville has been one of the fastest-growing parts of Ottawa, adding roughly a thousand homes and apartments a year through the recent boom. That construction sits on engineered fill, and engineered fill keeps consolidating for years after the builder hands over the keys. It does not settle evenly. A patio built on a shallow base over ground that is still moving will telegraph every dip within a few seasons.
What that means for your quote
We dig test holes before pricing. It sounds like a small thing and it is the single biggest difference between a patio that stays flat and one that does not.
On a village-core lot we are usually looking for what previous owners buried. On a post-war lot we are establishing whether we are over native soil or over an old septic field. On a newer subdivision lot we are measuring how much topsoil sits over the compacted clay underneath, because that clay holds water like a bathtub and the base has to be built to drain rather than to trap.
That last point is the one that surprises people. Ottawa’s freeze-thaw cycle is what destroys hardscaping here, and it does its damage through water. Water that cannot drain sits in the base, freezes, expands, and lifts whatever is on top of it. A deeper base is not about carrying weight so much as about giving that water somewhere to go. The full reasoning is in our piece on patio base depth and Ottawa’s freeze-thaw cycle.
What we usually build here
The common Stittsville project is a rear patio with a seating area, a front walkway that replaces a failing concrete path, and — where the grade calls for it — a low retaining wall to make a sloped yard usable.
Pool surrounds come up more often here than in most of the west end, simply because the newer lots were sized for them. A pool deck carries different loads and different drainage requirements than a garden patio, and it pulls permit questions along with it. We cover those in permits for retaining walls and pool decks in Ottawa.
Driveways are their own conversation. Driveway-grade pavers are thicker than patio pavers and the base beneath them is deeper again, because they carry vehicle loads rather than furniture.
Choosing a contractor
Since March 1, 2026 the City of Ottawa has required hardscaping contractors to hold a municipal business licence. That requirement exists precisely because this trade attracted operators who did not stay around for the second winter. Ask to see the licence. Any legitimate contractor will produce it without hesitation.
Then ask what base depth they are quoting and why. A contractor who gives you the same number for every lot in Stittsville has not looked at your lot.
We quote as a fixed-price scope with the base depth, paver line and edge detailing written out, so you are comparing the actual work rather than a round number at the bottom of a page. You can see the full service on our hardscaping page, or the local version on our Stittsville hardscaping page.
