Your Spring Decking Checklist: Build or Refresh with Confidence

Spring in Ontario is the perfect time to roll up your sleeves and bring outdoor projects to life. Whether you're planning to build a brand-new deck or give your current one a well-deserved refresh, this checklist will help you move forward with confidence—and all the right materials.

Inspect Your Existing Deck (If Applicable)

Before anything else, walk through your current deck with a critical eye. Look for signs of:

• Rot or moisture damage, especially in shaded corners where snow tends to linger.
• Cracked or warped boards from frost-heave or extreme temperature swings.
• Rusty fasteners—these can stain composite surfaces or compromise safety.

Pro tip: Use a screwdriver to gently test suspect spots—if the wood feels soft or flakes easily, it’s likely time to replace. And don't skip the wooden deck stairs—they often wear down faster than main decking boards due to extra foot traffic and water exposure.

Plan Your Decking Project

A successful build starts with a clear plan. Ask yourself:

• How will the space be used? For dining, lounging, gardening?
• Will it connect to other structures, like a shed or pool?
• Is it exposed to full sun, or shaded?

Sketch your layout, then factor in practical elements like railing placement, drainage slope, and access points (e.g., stairs, gates).

Planning tip: Consider using a deck framing designer app or tool to visualize multi-tier designs or integrate storage solutions beneath the deck.

And of course—check local bylaws or consult your municipality for permit requirements before building.

Choose Your Materials Wisely

Your choice of material will affect not only the look of your deck, but also how much maintenance it will require—and how long it will last. Whether you’re building new or refreshing, here’s a quick comparison to help you decide what’s right for your project:

Pro tip: If you're considering composite deck boards like Trex, make sure to follow proper installation guidelines—including spacing between boards (typically ¼") to allow for drainage and expansion. Trex offers a variety of composite wood colours, including Toasted Sand, Foggy Wharf, Rocky Harbour, Honey Grove, and Tide Pool so you can choose a tone that complements your home’s exterior.

Don’t Forget Fasteners and Hardware

The wrong fastener can ruin even the best deck board. Use corrosion-resistant exterior screws—especially for pressure-treated wood, which can corrode standard metal.

Important: Trex decking and other composites often require hidden fasteners or manufacturer-approved clips to maintain warranties and ensure proper installation.

Consider:

• Joist hangers for added structural support
• Post anchors to secure railings and stairs
• Deck spacer tools for even, professional-looking board gaps

Have the Right Tools on Hand

You don’t need a pro’s toolbox to get professional results—but a few strategic tools go a long way:

• Circular saw or mitre saw for precision cuts
• Cordless drill/driver with multiple bits for fastening
• Measuring tape, speed square, and chalk line for accuracy
• Level to ensure safety and even footing
• Deck spacers or jigs for consistent gaps

Add Finishing Touches for a Complete Look

Even composite decks benefit from thoughtful finishing.

• Apply semi-transparent or solid stain on wooden railings or trim for extra contrast and protection.
• Choose door paint to match your new deck’s tone—it’s a subtle way to tie your entryway into your updated exterior.
• Use deck lights or solar caps to add safety and ambience after dark.
