For homeowners in Oshawa, from Samac and Eastdale to the growth areas of Kedron and Columbus, The Setting Stone Company builds a new flagstone patio, walkway or steps from the base up, and repairs tired ones.
Many yards here are old: the City’s Housing Needs Assessment counts 15,700 homes built in 1960 or before and another 23,330 from 1961 to 1980, out of 66,630. A patio or path that old may have sunk or tilted by now. If so, we lift it, find out why it moved, and rebuild from the ground up.

This city runs from the Lake Ontario shoreline to rolling hills in the north, and a 2024 City report calls the shoreline Iroquois sand plains. That is the wider area, not your lot, so we read the ground as we dig. Every flagstone patio in Oshawa gets proper excavation, geotextile fabric and a compacted granular base, with grading that moves water away from your foundation. Then we fit the stone piece by piece and finish the joints in polymeric sand or mortar.

We quote natural flagstone line by line once we have walked the yard. Building around a pool? We do flagstone surrounds too, and the City says an inground pool needs a Site Alteration Permit.

It can, depending on where your yard sits, whether the house is designated and how much ground moves. Start with the creeks. The Central Lake Ontario Conservation Authority (CLOCA) has jurisdiction over Oshawa Creek and Farewell Creek, and under Ontario Regulation 41/24 a permit may be needed before you place fill, alter grades or work close to a stream. If your yard backs onto the Oshawa Creek East Branch around Samac, or Harmony Creek near Second Marsh, begin with CLOCA’s permit page.
Then the house: over 40 properties in the city carry Ontario Heritage Act designation, and altering one needs a Heritage Permit. These rules can change, so confirm with the City before work starts, and we can help at the quote.
The City requires a Site Alteration Permit when landscaping imports or exports more than 20 cubic metres, so we estimate what comes out first.
Oshawa lots are designed to drain along the property line, and owners must maintain that, so we check the drainage before setting the patio height.
The City requires a Site Alteration Permit for elevation changes within 0.6 m of the line. City staff review a proposal at no cost.
No subcontracted labour on your job. The crew protects the property, cleans up and walks the finished stone with you.
Four steps, and no ballpark numbers over the phone, because no two backyards here are laid out or drained the same way.
We reply within 1 business day and book a free, no-obligation visit to your property.
Tim looks at access, slope, drainage and any old stone, and you talk through layout and stone choice before anything is priced.
You get a clear quote with each part of the job listed, and we confirm any permit or conservation check that applies.
Our crew digs, builds the base, sets the flagstone and clears the site. Then we go over the finished work with you.

The cost of a flagstone patio depends on its size, the stone you pick and how much has to come out first, which in a yard from the 1960s can mean an old slab and decades of fill. Moving more than 20 cubic metres of material in or out also needs a City Site Alteration Permit. We visit for free, measure, and give you a clear, itemized quote, because a phone ballpark would be a guess.
It depends on what the dig turns up. Coldspring, a natural stone quarrier, says sand set offers some flexibility and is usually easier to repair. Mortar is the rigid option, and Coldspring says it can last a long time where freeze-thaw cycles are minimal and surface drainage is ample. Oshawa's daily low reaches 0 C or colder on 130.1 days a year, by Environment Canada's normals, so treat that as a caution, not a ban.
Possibly, but the paperwork comes first. Oshawa's one heritage conservation district is at the airport's South Field and is not residential, so the question is whether your own property is designated. If it is, altering it needs a Heritage Permit, and the City recommends speaking with Planning Services before applying.
Flagstone suits a curving garden path or a patio behind an older Oshawa home, where irregular natural stone fits the house. Interlock pavers suit straight lines and regular patterns. Both get proper excavation and a compacted base from us, and we can quote either one after the site visit, so you can compare them on paper.
Yes, though a slope changes the plan. Oshawa climbs from the lakeshore to rolling hills in the north, and part of the city sits inside the provincial Greenbelt, which includes the Oak Ridges Moraine. A sloped yard often needs flagstone steps between levels or a low retaining wall, and the City lists new retaining walls as Site Alteration Permit work. We work out the levels on site and grade so water runs away from the house.

We recently had our walkway completed by The Setting Stone Company, and we honestly couldn’t be happier. From the first conversation to the finished project, the entire experience was exceptional. The craftsmanship and attention to detail are incredible—you can truly see the pride that goes into every stone that is laid.
