LOW-MAINTENANCE. HIGH-IMPACT.

A Better Deck Starts With a Better Plan

Composite decking gives you the warmth and character of wood with far less ongoing upkeep. But the boards are only one part of a deck that looks right and performs well. Layout, framing, drainage, fasteners, stairs, railings, lighting, and the connection to your landscape all shape the result.

Diamond Decks & Pools designs and builds the complete deck as one coordinated outdoor living space. We help you compare materials, plan comfortable zones for dining and relaxing, and choose details that complement your home instead of competing with it.

  • Custom layouts designed around your property and furniture plan
  • Low-maintenance capped composite decking options
  • Colour, grain, border, fascia, and railing guidance
  • Professional framing, stairs, and finish carpentry
  • One team from consultation through final walkthrough

WHY CHOOSE COMPOSITE

Made for Real Life Outdoors

A premium deck should make outdoor living easier, more comfortable, and more enjoyable year after year.

COMPOSITE VS. WOOD DECKING

Choose for the Years Ahead, Not Just Installation Day

Wood and composite can both create a beautiful deck. The better choice depends on how you balance upfront cost, ongoing maintenance, appearance, and long-term use. This side-by-side guide gives you a more useful place to start.

Composite Decking

  • Upfront investment: Higher than pressure-treated wood
  • Maintenance: Routine washing; no scheduled staining or sealing
  • Surface: Consistent and splinter-free
  • Appearance: Wide range of colours, grains, borders, and fascia
  • Weather resistance: Engineered to resist moisture and common wear
  • Warranty: Select Trex collections carry 25-, 35-, or 50-year limited warranties
  • Best fit: Homeowners who value lower upkeep and long-term consistency

Natural Wood Decking

  • Upfront investment: Often lower for pressure-treated lumber
  • Maintenance: Periodic cleaning, staining, sealing, and refinishing
  • Surface: Natural character that can check or splinter as it ages
  • Appearance: Authentic grain with stain and species choices
  • Weather resistance: Performance depends heavily on finish and upkeep
  • Warranty: Varies by lumber product and treatment
  • Best fit: Homeowners who prefer natural wood and accept regular maintenance

Warranty length and coverage vary by product and manufacturer terms. We review current documentation with you before material selection.

CUSTOM DECK DESIGN

Designed as an Extension of Your Home

Before we draw the deck, we look at how people will move through it. Where does the grill belong? How much room does a dining table need? Where will afternoon sun land? Which view should stay open? Good answers create a deck that feels generous and intuitive instead of simply filling space.

  • Single-level, multi-level, raised, and poolside layouts
  • Dining, cooking, lounge, and circulation zones
  • Contrasting borders and custom board direction
  • Glass, aluminum, or composite railings
  • Built-in benches, planters, and privacy screens
  • Pergolas, shade structures, and outdoor kitchens
  • Integrated stair, post, and under-rail lighting
  • Transitions to patios, pools, pathways, and gardens

PLANNING YOUR INVESTMENT

What Does a Composite Deck Cost in the GTA?

Composite decking costs more up front than pressure-treated wood, but a reliable estimate depends on far more than a square-foot number. A simple ground-level platform and a raised multi-level deck with stairs, glass railings, lighting, and engineering are very different projects.

Size and Layout

Overall square footage, levels, board direction, borders, stairs, and landings.

Structure and Access

Footings, framing, elevation, site access, demolition, engineering, and permit requirements.

Decking Collection

Board line, colour, profile, warranty, fastening system, fascia, and trim details.

Features and Finishes

Railings, privacy screens, lighting, pergolas, built-ins, outdoor kitchens, and landscaping.

Our estimate separates the core build from optional upgrades so you can see where the investment goes and make confident decisions without surprise add-ons.

WHAT IS UNDERNEATH MATTERS

A Composite Deck is Only as Good as What Supports it

Composite boards are engineered products with specific requirements for framing, spacing, ventilation, fastening, and drainage. Careful installation protects the appearance of the deck, the performance of the structure, and applicable manufacturer coverage.

  • Site conditions and existing structures reviewed before design
  • Footing and framing layouts planned for the finished deck system
  • Manufacturer-specified spacing, gapping, and fastening followed
  • Flashing and moisture management considered where required
  • Stairs, guards, handrails, and lighting integrated into the plan
  • Municipal permit and inspection requirements reviewed for the project

COMPOSITE DECKING FAQS

Questions Worth Answering Before You Build

Good material decisions come from honest answers. These are the questions GTA homeowners ask us most often while planning a composite deck.

Ask Us About Your Deck

The final cost depends on deck size, height, framing, access, decking collection, stairs, railings, lighting, and other features. Composite material is typically a higher upfront investment than pressure-treated wood. We provide a detailed estimate that separates the core deck from optional upgrades so you can compare choices clearly.

For homeowners who want less recurring maintenance and a consistent appearance, composite can offer strong long-term value. It does not need scheduled staining or sealing and is designed to resist common moisture and weather damage. Natural wood may be the better fit when the lowest upfront cost or authentic wood grain is the priority.

All deck surfaces warm up in direct sun, and darker colours generally absorb more heat than lighter colours. Board composition and collection also matter. We consider sun exposure, colour, shade, and how the deck will be used when helping you choose a product.

Modern composite boards use textured surfaces designed for traction, but any outdoor surface can become slippery when wet, icy, dirty, or covered with organic debris. Product selection, drainage, cleaning, and careful stair design all contribute to safer everyday use.

Service life depends on the product, installation, substructure, exposure, and care. Current Trex collections include limited residential warranty options of 25, 35, or 50 years depending on the line. Warranty terms are not the same as a guaranteed lifespan, so we review the applicable documentation during selection.

Sometimes, but only after the existing structure and drainage conditions are assessed. A sound deck frame may be reusable if it meets current structural and layout requirements. Installation over concrete usually needs a properly designed sleeper or framing system that provides clearance, ventilation, and drainage.

Permit requirements depend on the municipality, deck size, height, attachment to the house, property conditions, and intended use. Some detached low decks may be exempt, while attached, elevated, or larger decks commonly require drawings and approval. We review the project conditions and help identify the required municipal steps before construction.

Routine cleaning is generally straightforward. Remove debris and wash the surface with soap, water, and a soft-bristle brush or other methods approved by the manufacturer. Spills are easiest to address promptly. We provide care guidance for the specific decking collection installed on your project.
