Thinking about refreshing or rebuilding your deck in the GTA? You’re not alone. Outdoor living is huge in 2025—and a smart deck remodel can boost everyday comfort and resale appeal. Homeowners can see a ~65–75% return on their investment in a new deck, depending on market conditions and finish quality. In many Toronto remodels, labour can account for ~40-60% of the total spend — though in high-end builds, premium deck materials might push that split lower in favour of materials.

Below is a clear, Toronto-specific breakdown of real costs, including average costs for deck remodels in Toronto to help set your expectations, what drives them up or down, code/permit must-knows, and how to plan a project that fits both your budget and goals.

Remodel vs Replacement: Making the Right Choice for Your Deck

When deciding between remodelling your existing deck or opting for a full replacement, several factors come into play that can significantly impact both your budget and the outcome.

Remodel: Repair and Refresh

A remodel typically involves repairing or upgrading parts of your current deck while retaining the existing structure where possible. This approach is often more cost-effective, especially when the deck has minor issues like loose boards, worn railings, or cosmetic damage. Remodel costs can vary depending on the extent of repairs and materials used, but generally fall below the cost of a full replacement.

Advantages of remodelling include:

  • Lower repair costs compared to full replacement.
  • Less disruption and shorter project timelines.
  • Ability to update design elements, such as adding custom railings or built-in seating.
  • Preservation of existing footings and structure if they meet current building codes.

However, remodels may not be suitable if your deck has extensive damage or structural issues that compromise safety.

Replacement: Starting Fresh

Deck replacement involves dismantling the old deck entirely and constructing a new one from the ground up. This option is ideal when the deck suffers from significant rot, extensive structural damage, or when you want to completely redesign your outdoor space with high-end materials and custom features.

Replacement costs are higher due to demolition, disposal, new materials, and labour, but offer benefits such as:

  • Compliance with the latest local building codes and safety standards.
  • Opportunity to choose modern, low-maintenance materials like composite decking or premium PVC.
  • Enhanced aesthetic appeal and increased property value.
  • Longer lifespan and reduced repair costs over time.

Factors Influencing Your Decision

Ultimately, the choice between remodel and replacement will vary depending on:

  • The age and condition of your existing deck.
  • The presence of structural issues or extensive damage.
  • Your budget and willingness to invest in high-end materials.
  • Desired design changes and additional custom features.
  • Local building permit requirements and inspections.

Consulting with experienced contractors and obtaining multiple quotes can help you assess repair costs versus replacement expenses, ensuring you make an informed decision that fits both your budget and outdoor living goals.

Deck Remodel vs. Replacement Cost in Toronto

A remodel often means removing all or part of the existing structure and rebuilding to current code. Occasionally, engineer-approved footings can be reused, but many projects replace foundations entirely—either with new concrete footings or helical piles—to secure long-term durability.

Deck Type Typical Range
(All-In)
What You Get
Pressure-Treated (Wood) $50–$70/sq. ft. Quick refresh, value-driven, higher upkeep
Mid-Range Composite $60–$100+/sq. ft. Low-maintenance surface, clean look, strong resale
Premium PVC / Advanced Composite $90–$130+/sq. ft. Top performance, cool-to-the-touch options, high-end details

What Drives the Price (Up or Down)?

1) Size & Shape

Deck size, measured in square feet, is a primary factor. Straight rectangles cost less per square foot than multi-level shapes, curves, or heavy picture-framing.

2) Deck Material

  • Pressure-treated wood: Costs between $30 and $50 per square foot. Budget-friendly but higher maintenance over time; prone to decomposition, fading, and splintering.
  • Cedar: Costs between $40 and $70 per square foot. Warmer look, costs more than pressure-treated wood, still needs upkeep; affordable to repair compared to composite.
  • Composite/PVC: Costs between $55 and $85 per square foot. Higher upfront, much lower maintenance; material costs vary widely by brand and line.

3) Structure & Foundations

New footings must reach below the frost line (~1.2 m) or use engineered helical piles, which install quickly and suit tight urban sites.

4) Railings & Stairs

  • Aluminum picket: Cost-effective, durable.
  • Glass/aluminum hybrid: Premium look, higher price.

More stairs and custom features like built-in seating and lighting increase labour and material costs.

5) Site Conditions

Tight downtown access, uneven grading, or existing deck removal may increase labour time and disposal costs.

6) Permits, Compliance & Inspections

Most decks attached to the home or higher than ~24 in (600 mm) require a permit. Toronto’s 2025 residential deck permit fee is $206.53. Compliance with local building codes ensures safety and structural integrity. Inspections typically cover footings/piles, framing, and final approval.

For a step-by-step overview, see Green Side Up’s Deck Building Permits Guide.

7) Integrated Plumbing

For decks featuring outdoor kitchens, rooftop setups, custom built-ins, pergolas, or water features, integrated plumbing systems add complexity and cost to the project.

8) Privacy & Wind Screens

Framed aluminum, composite, or glass privacy screens provide added comfort and style but increase both material and labour expenses.

9) Skirting & Access Hatches

Adding skirting and access hatches improves the deck’s aesthetics and functionality by keeping out critters and providing convenient under-deck access.

10) Seasonality, Market Inputs & Labour Costs

Lumber and component pricing remain volatile. Market demand and inflation have increased deck costs, with further rises projected. Labour rates swing with season, complexity, and crew experience. They tend to be higher in Toronto than in rural areas, averaging $40–$75/sq. ft. for professional deck labour. Booking shoulder seasons can help—though winter builds often need temporary protection and can reduce productivity.

Why Many Toronto Homeowners Choose Composite in 2025

Composite/PVC decking delivers low maintenance (no annual staining), colour stability, and hidden-fastener aesthetics. For Toronto climates and sun exposure, Trex (Enhance, Select, Transcend) and TimberTech (Composite lines and Advanced PVC) cover the full spectrum—from value to premium, cooler-underfoot options. Although upfront costs are higher than wood, many homeowners save thousands over the deck’s lifespan in maintenance and refinishing.
