Who best deck building in GTA (Greater Toronto Area)? Captain Handy is a licensed, insured deck contractor working throughout the GTA — the City of Toronto, York Region, Peel Region, Durham Region and Halton Region — building pressure treated, cedar, composite and PVC decks for backyards, elevated properties, rooftop terraces and pool surrounds alike. Most GTA deck installation projects run 2 to 4 weeks from approved design to completion, and every quote across the region starts free, regardless of which municipality your property sits in.
What does deck building cost across the GTA? Pricing is fairly consistent region-wide: pressure treated deck construction runs $45 to $75 per square foot, cedar deck work runs $60 to $95 per square foot, and composite deck or PVC decking runs $75 to $130 per square foot. A standard 300 sq ft backyard deck typically lands between $18,000 and $35,000 installed anywhere in the GTA, with the exact number shaped less by which city you’re in and more by lot access, grade and the specific material you choose.
One Deck Contractor, Five Very Different Regions
The GTA isn’t one market — it’s five. Downtown Toronto and North York bring narrow urban lots, laneway access issues and rooftop deck opportunities you won’t find in the suburbs. York Region — Markham, Vaughan, Richmond Hill, Newmarket, King Township — mixes dense newer subdivisions with large estate lots and horse country. Peel Region, covering Mississauga and Brampton, is mostly established suburban stock with a wide range of lot sizes. Durham Region, including Ajax, Whitby and Oshawa, tends toward larger suburban and semi-rural lots east of Toronto. And Halton Region — Oakville, Burlington, Milton, Halton Hills — blends upscale suburban builds with semi-rural properties along the Credit River and Niagara Escarpment.
Building across all five regions means we see the full range of what a GTA backyard can be, and we bring that experience to every custom deck design regardless of which municipality issues the permit.
Materials for Every GTA Climate and Lot Type
Pressure treated deck lumber is still the most common starting point across the region — affordable, structurally proven, and easy to stain once it’s dried. Cedar decking is the natural step up for homeowners who want a warmer look and better rot resistance, and it’s a popular choice from Toronto’s older neighbourhoods to York Region’s estate properties.
Composite decking and PVC decking (Trex, Fiberon, TimberTech) have become the default for GTA homeowners who want to skip annual staining — they hold up to our freeze-thaw winters with minimal upkeep and a 25-plus year lifespan. For premium builds, especially on larger Peel and York Region lots, an ipe deck or a higher-end trex deck gives the space a dense, furniture-grade finish that’s built to last.
3D Deck Design Wherever You’re Building
Every custom deck design we build starts with a 3D deck design, whether it’s a compact rooftop deck in downtown Toronto or a multi-level cedar deck on a Halton Hills property. Seeing the layout, railing style and material on screen before construction starts matters just as much on a tight urban lot as it does on a sprawling York Region estate — it’s how we catch site-specific problems before they become expensive change orders.
Backyard, Elevated, Rooftop and Pool Decks Across the Region
Backyard deck builds remain our most common project type across every GTA municipality, but the variations shift by region: elevated deck work is common on Halton Hills’ and York Region’s sloped and ravine lots, rooftop deck projects concentrate in Toronto and North York where flat-roof access is available, and pool deck builder requests come from every corner of the GTA as more homeowners add in-ground pools. We spec composite decking and PVC decking around pools specifically for slip resistance, regardless of which region the pool is in.
Deck Permits: A Different Municipality for Every City
A deck permit is required almost everywhere in the GTA, but the authority issuing it changes by city — City of Toronto, City of Vaughan, City of Markham, Town of Richmond Hill, Township of King, City of Mississauga, City of Brampton, Town of Ajax, Town of Whitby, City of Oshawa, Town of Oakville, City of Burlington, Town of Milton, Town of Halton Hills, and more. Navigating a different set of permit forms and requirements for each municipality is exactly the kind of friction we handle for GTA homeowners — we prepare drawings and manage the submission regardless of which city’s process applies to your property.
Deck Renovation Across an Aging Housing Stock
The GTA’s housing stock spans decades, from 1950s Toronto bungalows to brand-new Durham Region subdivisions, and deck renovation needs vary accordingly. A lot of our renovation calls come from homeowners across York and Peel Region whose original pressure treated deck has aged out — soft boards, failing railings, footings that no longer meet current code. We’ll tell you honestly whether a renovation makes sense for your specific property or whether a full rebuild is the better long-term investment.
