Areas we serve

Kanata. Backyard transformations across Kanata Lakes, Bridlewood, Morgan's Grant, Beaverbrook, and Katimavik. Typical Kanata builds: 400-600 sq ft patio + fire pit + seat wall — $20,000-$45,000 range.

Barrhaven. Backyard builds across Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. Small Barrhaven lots need clever multi-purpose design — seat walls that double as planters, etc.

Orleans. Backyard work across Avalon, Fallingbrook, Chapel Hill, Convent Glen, and Queenswood Heights. Sloped Orleans yards often need multi-level patios with retaining walls — $25,000-$50,000 typical.

Nepean. Backyard transformations across Centrepointe, Tanglewood, Crestview, and Trend-Arlington. Mature Nepean yards mean tree-aware design and shade-friendly paver colours.

Stittsville. Large-lot backyard builds across Jackson Trails, Crossing Bridge Estates, and Amberwood. Stittsville supports full outdoor-living builds — kitchen, fire pit, multi-level patio — $40,000-$80,000+ range.

Gloucester. Backyard installs across Beacon Hill, Blackburn Hamlet, and Hunt Club. Gloucester slopes often need engineered retaining walls before the patio — we design and build both together.

Manotick. Estate-scale backyards across Mahogany, Manotick Estates, Long Island, and Manotick Village. Pool surrounds, outdoor kitchens, multi-level entertaining spaces — $60,000-$150,000+ typical.

Riverside South. Backyard builds across Honey Gables and the Riverside South village. New-build yards usually start as bare grass — we design from scratch with patio, walks, and planters.

Centretown. Tight courtyard backyards across the Golden Triangle and Centretown West. Small downtown spaces benefit from built-in seating, planters, and vertical garden walls.

Westboro. Heritage backyard installs across Westboro Beach, Highland Park, and McKellar Park. Older Westboro yards often have mature plantings worth preserving — we work around them with careful excavation.

Alta Vista. Backyard transformations across Heron Park, Faircrest Heights, and Playfair Park. Sloped Alta Vista yards usually need a retaining wall + patio combination — we design both as one project.

The Glebe. Heritage backyard builds across the Glebe and the Old Ottawa South border. Narrow lots, neighbour-adjacent fence lines, original heritage hardscape — careful design and access coordination.

Backyard interlock FAQs

How much does a backyard interlock project cost in Ottawa?

Backyard interlock projects in Ottawa typically start around $10,000 for a small patio and can reach $50,000 or more for a full backyard with patios, walls, steps, fire pits, and lighting. We provide written quotes after an on-site consultation.

How long does a backyard interlock project take?

Small patio projects are usually finished in 1 to 2 weeks. Full backyard transformations with walls, steps, and lighting can take 3 to 6 weeks depending on scope and weather.

Can you design my backyard?

Yes. We provide design consultation and a layout sketch as part of our quoting process. For larger projects we can produce a more detailed plan with paver and material samples.

Do you do retaining walls and steps?

Yes. We build engineered retaining walls and interlock steps as part of most backyard projects, including the proper drainage and base preparation they require.

Do you install outdoor lighting?

Yes. We install low-voltage landscape lighting along walkways, steps, walls, and patio borders. Lighting cable is run while the hardscape is being built.

Can you build a fire pit in my backyard?

Yes. We build interlock fire pits with proper drainage, fire-rated inner liners, and capstones. We confirm local bylaw requirements before construction.

Will heavy machinery damage my lawn?

We protect lawns and gardens with plywood pathways and access mats wherever possible, and we re-grade and seed any disturbed areas when we leave.

Do you handle drainage problems?

Yes. We grade hardscape to direct water away from the house, install French drains where needed, and tie patio drainage into existing weeping tile or surface drains.

Best time of year to start a backyard project?

Most Ottawa backyard interlock projects run from April through November. Booking in winter or early spring usually gives you better scheduling options.

Do you offer backyard interlock near me in Ottawa?

Yes. We design and build backyard interlock projects across Ottawa, including Kanata, Barrhaven, Orleans, Nepean, Stittsville, Gloucester, Manotick, Riverside South, Centretown, Westboro, Alta Vista, and The Glebe.
