What is interlock staircases?

Outdoor staircases connect levels, improve access, and create a finished architectural look across your front entrance, side yard, or backyard. A quality staircase needs precise rise/run consistency, proper foundation support, and clean tie-ins to surrounding interlock or landscape features. We design and build interlock and block stair systems that are both durable and comfortable to use, with attention to tread depth, edge alignment, and long-term stability. Whether you need a small front entry staircase, wide backyard terrace steps, or stairs integrated into a retaining wall design, we build with safety, drainage, and visual balance in mind so the result feels intentional and high-end.

Safe elevation transitions

Consistent step geometry and stable construction for confident footing.

Integrated design

Stairs that tie in seamlessly with your driveway, walkway, patio, or wall.

Our process

A clean finish starts with the steps you do not see. We build from the base up.

Step 1

Measure + stair design

We calculate rise/run and layout based on code-minded, comfortable stair geometry.

Step 2

Excavation + structural prep

We build a stable base and supports to handle daily traffic and seasonal movement.

Step 3

Install treads/risers + edges

We install step components with tight alignment and clean side transitions.

Step 4

Detail + final walkthrough

We complete finishing details, confirm consistency, and review care guidance with you.

Pricing factors

Exact pricing depends on the project. These are the main drivers:

Number of steps and overall staircase width

Material system (blocks, slabs, coping, accent borders)

Site access and existing structure removal

Need for retaining wall integration or landings

Lighting conduit, rail prep, or additional finishes

Drainage and grading corrections around stairs

FAQ

Common questions about interlock staircases.

+Do outdoor stairs settle over time?
They can if the base wasn't built right, which is unfortunately common with older builds. We excavate to the right depth, compact the base in layers, and build a solid foundation for each step so everything stays put. Ottawa's freeze-thaw cycles put extra stress on outdoor stairs, which is why proper base prep matters even more here.
+Can you match the staircase to existing interlock?
Yes, we do this regularly. If your pavers are still being manufactured, we can source the same product for a seamless match. Even if the exact product isn't available anymore, we can find something very close or use complementary materials and borders to tie everything together visually.
+How do you make sure stairs are safe?
Safety comes down to consistency and stability. Every step needs to have the same rise and run so your body naturally knows what to expect as you walk up or down. We also make sure treads are solidly set with no wobble, and we build in proper drainage so water doesn't pool on the steps and freeze in winter.
+Can stairs be combined with retaining walls?
Yes, this is actually one of the most popular combinations we do. When you have a grade change that needs a retaining wall, adding stairs into the wall design gives you functional access between levels without taking up extra yard space. It also looks great because everything is built from the same materials and the transitions are clean.
+Do you offer front entrance staircase upgrades?
Absolutely, front entrance stairs are one of our most popular projects. Upgrading old concrete or crumbling steps with clean interlock or stone treads makes a huge difference in curb appeal. We handle everything from removing the old steps to building a proper foundation and installing new risers and treads that match or complement your existing walkway or driveway.
+How long does a staircase project take?
Most staircase projects take 2 to 4 days from start to finish. A simple 3 or 4 step front entrance can sometimes be done in a day or two, while larger multi-level staircases integrated with retaining walls take longer. We'll give you a clear timeline after the site visit so you can plan accordingly.
