A 14×20 deck in Ontario usually lands in the mid five-figure range once you include materials, framing, stairs, and railings. The real price depends on the decking material, height off grade, demo, and whether the project needs permits or special footing work. GTA Grizzly gives free estimates and locked-price proposals, and projects under $30K get a detailed proposal within 24 hours.
A 20×20 deck usually costs more than a smaller patio-level build because of the extra square footage, support structure, and finishing details. In many GTA homes, the final number depends most on whether you choose cedar, pressure-treated, or composite, plus railings and stairs. If you want a clear number instead of a rough range, GTA Grizzly can price it from a free site visit and give you a locked-price proposal.
The 3 4 5 rule for decks is a simple way to check for a square corner during layout. If one side measures 3 feet, the next 4 feet, and the diagonal is 5 feet, the corner is square. On a real build, small layout errors can affect the whole frame, which is why GTA Grizzly uses on-site precision and checks the structure before the deck surface goes down.
The 3/4/5 rule for decks is the same squaring method used to confirm a true 90-degree corner. It’s useful on new framing and also when correcting an existing layout before boards are installed. If a deck is already built, the next step is usually to measure for settlement, rot, or movement before deciding whether repair or rebuild makes more sense.
Sometimes a very small, simple deck can start around that budget, but $5000 is usually tight once you add proper framing, footings, permits, and safe stairs. In many cases, a realistic build costs more because the structure has to meet code and handle Toronto weather. GTA Grizzly offers free estimates, so you can see quickly whether your scope fits a smaller build or needs a bigger plan.
A 20×20 deck to build typically depends on the material, height, access, and whether you want railings, stairs, or built-in features. Composite usually costs more than pressure-treated lumber, but it’s often chosen for lower upkeep over time. GTA Grizzly can price the whole scope with a locked-price proposal, and you’ll know the cost before work starts.
A 12×12 deck in Ontario is often the kind of project that can be quoted quickly once the site is measured and the material is chosen. The biggest price drivers are height, foundation type, railing needs, and whether there’s an old deck to remove first. For projects under $30K, GTA Grizzly provides a detailed proposal within 24 hours.
No, you shouldn’t lay decking directly on soil. Deck boards need proper framing and support, or the structure can shift, trap moisture, and fail early. If you’re planning a low platform or ground-level build, the next question is usually whether you need footings or a gravel base, and that depends on the deck size and local code.
You should expect the price to reflect the size of the deck, the material, and how much structural work is needed underneath. In the GTA, a simple build can be far less than a multi-level composite project with stairs and glass railings. GTA Grizzly keeps pricing clear with free estimates, no surprise bills, and a locked-price proposal so you know what you’re paying for.
The 3 4 5 rule for decking is used to confirm square corners before the surface boards are installed. It helps avoid crooked framing, uneven board lines, and awkward stair openings. If the deck is already underway, the next practical check is whether the frame is square at each corner, not just one corner.
A 20×20 composite deck usually costs more than pressure-treated wood because the material and installation details are different. For this size, most homeowners should budget for framing, proper support, board system, stairs, and railings if needed. GTA Grizzly offers a free consultation, and projects under $30K receive a detailed proposal within 24 hours so you can compare the full scope clearly.
The 3/4/5 rule for decking is a layout check for square corners, and it’s especially helpful before any joists or boards are fastened down. If the measurement doesn’t line up, the frame needs to be corrected early or the finished deck can look off. For a new build, that’s one of the first things a good crew should confirm on site.
