Flagstone is one of the most sought-after materials in hardscaping — and for good reason. Its natural texture, earthy tones, and irregular shapes create outdoor surfaces that feel both timeless and unique. No two flagstone patios look exactly alike, which is exactly what homeowners across Oshawa, Courtice, Bowmanville, and Newcastle love about it.
At The Setting Stone Company, we install flagstone patios, walkways, front entrance steps, and pool surrounds using proven techniques that keep stones stable and level through Ontario’s freeze-thaw cycles. Every installation starts with proper base preparation — the foundation that separates a flagstone surface that lasts decades from one that shifts within a few seasons.
Our goal with every flagstone project is to create a surface that feels natural and intentional — like the stone was always meant to be there
We source natural flagstone in a range of colours and profiles, helping you match your home’s exterior and your personal style.

A custom-designed patio is the centrepiece of any backyard. We lay flagstone in natural or cut patterns, with tight or open joints, to create a surface built for entertaining, relaxing, and enjoying Ontario summers.
Stepping stone paths and full flagstone walkways connect your outdoor spaces with style. We design them to flow naturally with your landscape and grade them for proper water drainage.
Your entrance is the first thing visitors see. We build flagstone steps and landings that are both structurally solid and visually impressive — a major upgrade over poured concrete.
Shifting, cracking, or sunken flagstone is a common problem in Ontario due to frost heave. We lift, rebed, and relay existing stone to restore a level, safe surface without a full replacement.
Flagstone installation looks straightforward — but done incorrectly, it leads to uneven surfaces, weed growth, and frost heave within a few years. Our team has installed flagstone across Clarington and Durham Region for over 15 years, and we understand how Ontario’s climate affects natural stone. We get the base right so the surface lasts.

We excavate to the correct depth, compact a granular base, and install geotextile fabric to block weeds and prevent settling — the step most contractors overlook.
We source natural flagstone rated for Ontario's freeze-thaw cycles, and finish every joint with weather-resistant polymeric sand or mortar suited to the specific application.
Every surface is graded to channel water away from your foundation and eliminate pooling — an essential step given Ontario's heavy spring rainfall and seasonal storms.
We take care to protect your lawn, gardens, and landscaping during the entire build. Once the job is done, we do a site cleanup before your final walkthrough.

We work with a variety of natural stone options commonly used in Ontario, including limestone, sandstone, slate, and quartzite. Each has different colour profiles and surface textures, and we'll help you choose the right one for your project and budget.
Most residential flagstone patios take 2 to 5 days to complete, depending on the size of the space, site conditions, and the complexity of the pattern. We provide an estimated timeline before any work begins.
Both methods are used depending on the application. Sand-set (dry-laid) flagstone is excellent for patios and walkways and allows for easier repairs. Mortar-set flagstone is better suited for steps and raised surfaces where structural rigidity is required. We'll recommend the right approach for your project.
We use polymeric sand, which hardens when wet and resists weed growth and insect infiltration. For mortar-set applications, jointing compound provides a solid seal. Proper installation is the best long-term defence against weeds.
Yes — if your existing stones are in good condition but have shifted, sunken, or heaved due to frost, we can lift and relay them with a fresh base. This is often significantly more cost-effective than full replacement.
