Usually not for a full custom deck, especially in Toronto, because materials, framing, footings, and code-compliant railings can push the scope higher. As a deck builder toronto homeowners call for larger projects, GTA Grizzly gives free estimates and locked-price proposals, so you can see the real number before work starts. The next question is usually what size and finish changes the price most: stairs, railings, composite boards, and a harder site can all move the total.
A 20×20 deck usually lands in a wide range because the final price depends on material, height, railing type, and access to the yard. For custom decks toronto projects, the safest step is a free consultation and a locked-price proposal, and projects under $30K get a detailed proposal within 24 hours. If you’re comparing quotes, ask whether footings, railings, and demolition are included in the number you’re being shown.
The 3-4-5 rule is a simple way to check for a square corner: one side measures 3 units, the other 4, and the diagonal should measure 5. It’s a layout check, not a design style, and a toronto deck contractor will still verify framing, footing placement, and code details before building. If the corner is off, even a small error can affect deck boards, railings, and stairs later.
The 3/4/5 rule is the same squaring method, just written with slashes instead of spaces. On a properly squared frame, those three measurements form a true right angle, which helps the deck sit straight and makes the finish cleaner. For a toronto deck, the bigger question after that is whether the base is level and properly supported, because layout alone doesn’t solve drainage or settlement.
Most deck building toronto projects cost more or less based on size, material, elevation, railings, stairs, and site conditions. GTA Grizzly provides free estimates, locked-price proposals, and no hidden fees, so you know the budget before construction starts. If the project is under $30K, you’ll get a detailed proposal within 24 hours, which makes planning a lot easier.
A 14×20 deck cost in Ontario can vary a lot because a low, simple platform is very different from an elevated deck with railings and stairs. For deck contractors toronto homeowners trust, the biggest price drivers are framing complexity, board choice, and whether demolition or permit work is included. If you want a real number, a site visit and written quote are the fastest way to narrow it down.
Often yes, depending on the deck size, height, and attachment to the home. GTA Grizzly handles permit paperwork for the projects it takes on, so you don’t have to guess your way through the process. The best next step is a consultation, because the permit question usually depends on the exact plan and where the deck will sit on the lot.
A 20×20 composite deck usually costs more than pressure-treated wood because the material and installation are both more specialized. With composite, details like hidden fasteners, stair count, railing style, and substructure can change the total quickly for a toronto deck builder. GTA Grizzly gives free estimates and locked pricing, so you get a clear proposal before anything is ordered.
The 3/4/5 rule for decking is a quick field test to confirm a frame corner is square before the boards go down. It helps prevent crooked seams and awkward trim lines, but it doesn’t replace proper leveling, fastening, or structural checks. If you’re planning a deck installation toronto homeowners can use for years, the next thing to confirm is whether the structure meets code and handles drainage correctly.
No, decking should not be laid directly on soil because the wood or composite can shift, trap moisture, and settle unevenly. A proper base, framing, and support system are needed for a durable build, which is why a decking company toronto homeowners hire should inspect the grade first. If you already have a low spot or soft ground, the fix usually starts with prep work, not the boards themselves.
A 12×12 deck cost in Ontario is usually lower than a larger build, but the final price still depends on height, access, railings, and whether you want wood or composite. GTA Grizzly offers free consultation and estimate services on all projects, plus a locked-price proposal so the number doesn’t change after the scope is approved. If the build is under $30K, you’ll also receive the detailed proposal within 24 hours.
A 14×20 deck cost to build can move up or down based on the material, finish level, and whether stairs, lighting, or railings are included. For custom decks, the most accurate pricing comes from a site visit, because yard access and grading can matter as much as square footage. GTA Grizzly’s free estimate and locked-price proposal make it easier to compare options without surprises.
