What Ottawa homeowners say
about their new decks & patios.

Timberline built us a two-level cedar deck with a pergola and built-in lighting. Professional, tidy, on time. Two years later it still looks brand new. Worth every penny.

We had a nightmare slope in our backyard for years. Timberline designed a gorgeous stone retaining wall and interlock patio that completely transformed the space. Couldn't be happier.

David L.Kanata, Ottawa

The outdoor kitchen they built is the talk of our neighbourhood. Natural stone counters, built-in grill, mini fridge — everything we asked for and more. The quality is remarkable.

Common questions about
Ottawa deck & patio projects.

How much does a deck or patio cost in Ottawa?
Every project is unique. Cost depends on size, materials, design complexity, and site conditions. A basic pressure-treated deck may start around $8,000–$12,000, while custom cedar or composite builds with lighting and railings can range from $20,000–$50,000+. We provide a detailed fixed-price quote after your free consultation.
How long does a project take to complete?
Timelines vary by project scope. A straightforward deck typically takes 3–7 days. Larger builds involving stone patios, pergolas, or outdoor kitchens may take 2–4 weeks. We provide a clear schedule at the start so you know exactly what to expect.
Do you pull permits for City of Ottawa projects?
Yes — we handle all required City of Ottawa building permits on your behalf. Decks over a certain height and many hardscape projects require permits, and we manage the entire process so you don't have to.
What materials do you use for Ottawa's climate?
We carefully select materials that handle our freeze-thaw cycles: pressure-treated lumber, western red cedar, capped composite decking, natural flagstone, porcelain tile, and engineered interlocking stone. We'll recommend the best options for your budget and lifestyle.
When is the best time to book?
Ottawa's building season runs May through October. We book up quickly in spring, so we recommend contacting us in winter or early spring to secure your preferred start date. We're happy to do consultations and design work during the off-season.
