A 12×12 deck in Ontario usually falls in the low-to-mid five figures, and the final price depends on material, height, railing, stairs, and site access. If you want a precise number for your yard, GTA Grizzly gives free consultations and a locked-price proposal, so the price you see is the price you pay. For projects under $30K, you can get a detailed proposal within 24 hours.
A 14×20 deck in Ontario typically costs more than a small platform deck because the footprint is larger and most builds need more framing, footings, and railing. The biggest cost drivers are material choice, elevation, and whether you add stairs, privacy screens, or a pergola. If your scope is under $30K, GTA Grizzly can send a detailed proposal within 24 hours, and every estimate is backed by a locked-price proposal.
A 20×20 deck usually sits in the mid-to-higher five-figure range, especially if you choose composite, upgraded railings, or a multi-level layout. A composite deck builder Newmarket homeowners trust will usually price it based on structure, finishes, and any grading or permit work needed. GTA Grizzly includes free consultations and can handle permit paperwork for the projects it takes on.
To build a 20×20 deck, most homeowners should budget for a custom quote rather than a flat price, because structure, material, and site conditions can change the total a lot. A deck contractor in Newmarket will also look at drainage, stairs, and railings before pricing the job. GTA Grizzly keeps pricing clear with locked-price proposals and no surprise bills without written approval.
The 3/4/5 rule is a simple framing check used to make sure corners are square: if one side measures 3 feet, the next should measure 4 feet, and the diagonal should measure 5 feet. It’s a quick way to verify layout before fastening the frame. If a deck is out of square early, fixing it then is far easier than after the boards and railings are on.
In many GTA homes, $5,000 is usually too tight for a full custom deck, but it may cover a very small, simple build or a limited refresh depending on materials and site conditions. For a realistic plan, GTA Grizzly offers a free consultation and estimate, so you can see what fits your budget before committing. If the scope is under $30K, you’ll get a detailed proposal within 24 hours.
The 3 4 5 rule for decks is the same square-check method used by experienced crews to keep the frame true during layout. It helps prevent crooked edges, uneven boards, and railing issues later. On a proper build, that kind of precision matters from the first footing to the final walkthrough.
No, you shouldn’t lay decking directly on soil because wood and composite boards need a proper structure, airflow, and stable support. Deck boards go on joists or a framed system, not on dirt, or you’ll invite sagging, moisture problems, and early failure. If your yard is starting from scratch, GTA Grizzly can assess grading, footing placement, and permit needs during a free consultation.
The 3 4 5 rule for decking is a layout method used to confirm the frame is square before the boards go down. It’s a small step, but it helps keep the deck clean, straight, and easier to finish properly. GTA Grizzly’s trusted crew uses on-site precision, and the team stays until every detail meets standard.
Sometimes a small, low deck may not need a permit in Ontario, but many elevated decks, attached decks, and builds with stairs or guardrails do. The rules depend on height, location, and how the structure connects to the house, so it’s worth checking before work starts. GTA Grizzly handles permit paperwork for the projects it takes on, which saves a lot of back-and-forth.
A 240 sq ft deck in Ontario often lands in a broad mid-range, with the final cost shaped by material, railing type, height, and site access. If you want a real number for a specific property, GTA Grizzly will price it clearly with a free estimate and a locked-price proposal. For projects under $30K, you can usually expect the detailed proposal within 24 hours.
Deck costs in Ontario vary widely, but most custom projects depend on size, material, structure, railings, and whether the site needs grading or permit work.

With over 20 years of experience and 136+ verified HomeStars reviews, the company keeps the process clear from quote to final walkthrough.
