The 3-4-5 rule is a quick way to check for a square corner during deck layout: if the side lengths are 3, 4, and 5 units, the angle is 90 degrees. Builders use it to keep posts, framing, and stair openings lined up before fastening anything down. If your deck frame is already out of square, the fix is usually in the layout and framing, not the boards. A deck builder in Vaughan can verify that during a site visit before the build starts.
Yes, but usually only for a small, simple deck with basic materials and minimal site work. In many GTA homes, $5,000 is more realistic for a compact platform than for a larger raised build, and grading, stairs, railings, or permits can move the price up fast. GTA Grizzly gives free estimates and locked-price proposals, so you’ll know the number before work begins. If your scope is under $30K, you can usually get a detailed proposal within 24 hours.
A 12×12 deck in Ontario usually lands in a broad range depending on material, height, railing, and access. For a small build like this, a pressure-treated deck is often the lower-cost option, while composite or cedar will cost more because of material and finishing details. GTA Grizzly’s proposal is locked, so the price you see is the price you pay. If you want, a free consultation can narrow it down based on your yard and code requirements.
A 20×20 deck should be priced based on structure, finish, railings, stairs, and whether the site needs grading or demolition first. For a build this size, most homeowners should expect the cost to move well above a small patio-deck budget, especially if they want composite, multiple levels, or custom details. GTA Grizzly can provide a free consultation and a locked-price proposal so you can compare options clearly. If the project is over $50K, a 3D design/render is included.
A 20×20 deck to build typically costs more than a basic square deck because the frame, footings, railings, and stair runs add material and labour. The final price also changes with composite versus cedar or pressure-treated lumber, plus any permit or site-prep work. GTA Grizzly handles permit paperwork for the projects it takes on and gives free estimates with no hidden fees. That makes it easier to plan the full budget before anything starts.
The 3/4/5 rule for decks is a simple squaring method used to make sure corners are true before framing is locked in. It helps prevent crooked layouts that can cause problems later with deck boards, railings, and stairs. If you’re planning a deck installation in Vaughan, the layout stage is where this matters most. A proper site measure before the build saves time and avoids costly rework.
A 14×20 deck in Ontario is usually priced as a mid-size project, so the material choice makes a big difference. Pressure-treated builds tend to sit lower, while cedar and composite raise the total because of the product cost and the extra finishing work. GTA Grizzly offers a free consultation and a detailed, locked-price proposal, which is the cleanest way to compare your options. For larger builds, weekly photo updates keep you in the loop while the work is underway.
No, decking should not be laid directly on soil because the boards and framing need proper support, drainage, and separation from ground moisture. Direct-to-soil installs usually shift, rot, or settle too fast, especially through GTA freeze-thaw cycles. If you’re thinking about a low platform, the substructure still needs to be built correctly. A deck contractor in Vaughan can inspect the grade and suggest the right foundation approach.
A 14×20 deck in Canada can vary a lot, but the biggest drivers are material type, height, stairs, railings, and whether the site needs prep work. In the GTA, composite and cedar usually cost more than pressure-treated lumber, but they also change the look and maintenance expectations. GTA Grizzly gives free estimates and no surprise bills, so any change has to be approved in writing. That keeps the budget clear from quote to final walkthrough.
Yes, many decks in Vaughan do need a permit, especially if they’re elevated, attached to the house, or large enough to trigger code requirements. GTA Grizzly handles permit paperwork for the projects it takes on, so you’re not left guessing what the city needs. The exact permit path depends on size, height, setbacks, and whether railings or stairs are part of the design. A consultation is the right next step before final drawings are prepared.
The 3-4-5 rule for decking is a layout check that helps builders confirm square corners before fastening the frame. It’s a small step, but it makes a big difference in how the deck boards, fascia, and rail lines up later. When a layout starts true, the finished deck looks cleaner and is easier to build accurately. That’s why experienced crews use it early, before the structure is locked in.
Yes, you can handle small repairs yourself if the problem is limited to a loose board, a trim piece, or minor surface wear. But if you see rot, movement, soft spots, or shifting posts, it’s safer to have it checked before the damage spreads. GTA Grizzly offers deck repair in Vaughan, and the team can tell you whether it needs a focused fix or a larger rebuild. If you’re unsure, a quick inspection is the easiest way to avoid making a small problem worse.
