Build It Your Way

From budget-conscious pressure-treated builds to premium composite masterpieces — we offer every decking material and style.

Composite Decking

The most popular choice for Ottawa homeowners who want a beautiful deck without the maintenance headaches. Composite boards are colour-stable, slip-resistant, and splinter-free. They won't fade, crack, or absorb moisture. Premium brands like Trex and TimberTech available.

Low maintenance | 25–30 year lifespan

Pressure-Treated Wood

The classic and most affordable deck material. Properly installed and sealed pressure-treated lumber delivers a strong, traditional deck that can last 15–20 years. It's the right choice for budget-conscious builds that don't sacrifice structural integrity.

Most affordable | 15–20 year lifespan

PVC Decking

100% synthetic decking that is completely waterproof, completely rot-proof, and carries a lifetime manufacturer's warranty. PVC boards stay cool underfoot, resist staining, and clean up with just soap and water. Ideal for pool surrounds and covered decks.

Lifetime warranty | Completely waterproof

Multi-Level Decks

When your yard has grade changes or you want to maximize outdoor living space, a multi-level deck is the answer. We custom-design connected deck platforms with integrated stairs, landings, and transitions — fully engineered for Ottawa's freeze-thaw conditions.

Custom designed | Full engineering included

Pergolas & Shade Structures

Extend the usability of your deck with a custom pergola or shade structure. We build freestanding and attached pergolas in cedar, aluminum, and composite materials. Add privacy screens, climbing plant supports, or retractable canopy hardware.

Custom priced | Cedar & aluminum options

Railings & Balusters

The railing defines the finished look of your deck. We install glass panel railings, cable railings, aluminum balusters, and traditional wood railings — all matched to your decking material and home style. Code-compliant on every build.

All styles available | Code-compliant always

A deck is only as good as its foundation. We engineer proper footings below frost depth, select the right ledger attachment method for your home's siding type, and frame every deck to exceed Ontario Building Code requirements.

Questions

Deck Building FAQs

In Ottawa, decks that are more than 24 inches (600mm) above grade typically require a building permit. We assist with permit applications as part of our service — we know the City of Ottawa's requirements and handle the paperwork so you don't have to.

Composite decking is our most popular choice — homeowners love the low-maintenance, long-lasting finish. Pressure-treated wood remains the top pick for budget-conscious builds. PVC is growing in popularity for its 100% waterproof properties and lifetime warranty.

Composite and PVC decks last 25–50 years with minimal maintenance. Pressure-treated wood decks last 15–20 years when properly sealed and maintained. The structure (framing and posts) is typically the longest-lasting component when built to code with the right materials.

Absolutely. We custom-design every deck around your yard's unique conditions — including trees, slopes, garden beds, and existing structures. Our crew has built around all manner of obstacles, and we see them as design opportunities rather than problems.

Most deck installations are completed in 3–7 days depending on size and complexity. Multi-level decks or those requiring pergolas and custom railings may take longer. We confirm the timeline in writing before starting any work.
