Areas We Serve

Choose your area below for local planning notes, nearby work, and deck services shaped around the kind of lots we actually see there.

Toronto

Toronto deck work is rarely a straight line. Old lots, tight access, tree roots, and close neighbors can change the plan fast.

Vaughan

Vaughan deck builds are usually about scale, clean detailing, and making a big back yard move properly. Bigger homes still need practical framing.

Mississauga

Mississauga deck jobs are often bigger backyard builds. Walkouts, pools, and family traffic drive the layout more than anything else.

Richmond Hill

Richmond Hill decks often sit behind bigger homes with raised rear entries, pool areas, and grading that needs real attention. This is not the place for loose layout work.

Brampton

Brampton builds a lot of big back yard decks. Walkouts, deep lots, and wide family use are common, so the structure needs to carry more than a simple platform job.

Caledon

Caledon deck work is about exposure, slope, and site logistics. Bigger lots do not make the build easier, they just make the mistakes bigger.

Etobicoke

Etobicoke gives you bigger lots than downtown Toronto, but that does not make the job easy. Older homes, mature trees, and changing rear grades still make the plan do the heavy lifting.

North York

North York deck jobs are a mix of older houses, additions, and newer rebuilds. The lot usually decides the hard part, not the decking board.

Scarborough

Scarborough deck work gets tricky when the yard drops, the wind picks up, or the back of the lot stays wet after a storm. A good looking deck still has to work in real weather.

Inglewood

Multi-Level Composite Deck with Glass Railing & Retaining Wall Integration

This project involved the construction of a large-scale multi-level composite deck system fully integrated with the surrounding landscape and pool environment. The deck begins along the side elevation of the home and extends toward the rear yard, gradually elevating as the grade drops. Built with high-performance composite decking boards and finished with aluminum glass railing, the structure delivers modern transparency and long-term durability. Three staircase access points create smooth transitions between the upper living deck, the lower entertainment platform, and the pool area. To stabilize the surrounding terrain and define outdoor zones, 6x6 timber retaining walls were installed around the deck perimeter. These retaining structures were finished with smart panel cladding, creating a refined appearance while forming structured flower and planting beds throughout the yard. The result is a cohesive outdoor living environment where structural decking, landscape retention, and greenery combine into a unified architectural system.

Mississauga

Permit-Approved Two-Level Composite Deck with Waterproof System

This project involved the design and construction of a fully custom two-level composite deck completed through a formal permit process, including detailed drawings, submission, and municipal approval. All structural plans were prepared in accordance with local building code requirements. Permit applications were submitted, reviewed, and approved prior to construction, ensuring full compliance with safety and engineering standards. The finished structure features upper and lower composite deck levels, built using high-performance decking boards engineered for long-term durability. The perimeter is completed with aluminum glass railing, delivering modern aesthetics and unobstructed views. A fully integrated waterproof drainage system was installed beneath both deck levels to protect structural components and maintain dry, usable space below. The underside of the upper deck was enclosed with a finished soffit ceiling system, incorporating hardwired recessed spotlights for ambient illumination. The lower level, with approximately four feet of clearance, was enclosed using smart panel cladding to create secure and functional storage space. All structural framing was carefully concealed, and support posts were wrapped in composite material to eliminate exposed wood surfaces. The result is a permit-approved, engineered outdoor structure built to the highest standards of durability, safety, and craftsmanship.

TimberTech® Poolside Composite Deck with Multi-Level Design

This project involved the construction of a large-scale TimberTech® composite deck built to enhance a luxury poolside setting. Designed to follow the natural layout of the backyard and pool perimeter, the deck incorporates subtle dip-step transitions that elevate certain sections while maintaining a smooth and cohesive flow. These level changes help define lounge and seating areas without disrupting the clean architectural lines of the structure. As a trusted Toronto deck builder, ATBCON installed high-performance TimberTech® composite decking boards selected for their durability, slip resistance, and resistance to moisture exposure — essential qualities for a poolside environment. The result is a spacious, elegant outdoor platform that surrounds the pool with modern refinement, creating dedicated zones for relaxation, entertaining, and seasonal enjoyment.

Custom Multi-Level Wood Deck with Waterfall Stairs & Under-Deck Storage

This project involved the construction of a custom second-storey wood deck that transitions into a multi-level outdoor living system, designed to maximize both functionality and architectural presence. The upper deck extends from the second floor of the home and steps down through a 4–5 step transition into a larger connected lower wood deck. From there, a custom-built waterfall-style staircase descends toward the yard, branching across multiple directional sections to create a dramatic and visually striking flow. Crafted with premium wood decking and finished with wood railings incorporating aluminum balusters, the structure balances natural warmth with structural durability. The underside of the deck was enclosed with smart panel cladding, transforming the lower area into functional storage space while maintaining a clean exterior finish. Additional custom features include built-in benches and integrated flower boxes, enhancing both comfort and visual character. Solar cap lights were installed on railing posts, and solar lighting was integrated along each stair tread, creating a refined and illuminated nighttime presence. This multi-level deck stands as a true craftsmanship project — blending structure, design complexity, and practical outdoor living.

Premium Composite Deck

This premium second-storey composite deck project was designed to enhance both the upper and lower outdoor living areas of a Toronto home. As an experienced Toronto deck builder, ATBCON constructed a modern composite deck featuring aluminum glass railings and a custom staircase with integrated solar lighting. A full waterproof under-deck system was installed to prevent water penetration over the walkout basement entrance. The lower level was further upgraded with a finished ceiling and recessed pot lighting, creating a sheltered and illuminated outdoor space beneath the deck. This project delivers both structural performance and elevated architectural appeal.

Brampton

Pressure Treated Wooden Deck

This project involved the construction of a second-storey pressure-treated wood deck for a residential property in Toronto. As an experienced Toronto deck builder, ATBCON designed and constructed a structurally reinforced outdoor space built for durability and long-term performance. The deck features custom wooden railings with aluminum pickets, along with a fully integrated landing and staircase to ensure safe and seamless access. Due to extremely dense soil conditions, post footings were excavated to approximately 4 feet to secure proper load-bearing support and long-term structural stability. The result is a professionally built 320 sq ft custom deck that combines structural integrity, safety, and refined outdoor living — a standard expected from a trusted Toronto deck builder.

Frequently Asked Questions

How much does a deck cost in Toronto?

Deck costs in Toronto typically range from $15,000 to $60,000+ depending on size, material, and complexity. A basic pressure-treated wood deck starts around $15,000–$25,000. Composite decks run $25,000–$45,000. Larger builds with stairs, railings, and pergolas can exceed $60,000. We provide free written quotes after a site visit so you get an accurate number for your specific property.

Do I need a permit to build a deck in Toronto?

Yes, in most cases. In Toronto, any deck over 24 inches from grade requires a building permit. Decks attached to the house also require permits regardless of height. We handle the full permit application process as part of our service — you do not need to navigate the city process on your own.

How long does it take to build a deck in the GTA?

Permit approvals typically take 2–8 weeks depending on the municipality. Once permits are approved, most deck builds take 1–3 weeks to complete. We provide a realistic timeline at the quote stage so you can plan around it.

What is the best deck material for Toronto winters?

Composite decking (such as Trex or TimberTech) performs best in the GTA's freeze-thaw climate. It resists moisture, splinters, and cracking without annual sealing. Pressure-treated wood is a cost-effective alternative that requires more maintenance. Cedar is a popular mid-range option. We advise on the right material based on your budget, usage, and exposure.

Do you build composite decks in the GTA?

Yes — composite decking is one of our most common builds across Toronto, Mississauga, Vaughan, Brampton, and surrounding GTA cities. We work with major composite brands and can advise on colour, texture, and railing combinations that suit your home and yard.
