The kitchen is the hub of any home. But once the warm weather rolls around, in most cases the deck becomes party central, serving as an outdoor dining room, living room, and food preparation space, all in one. If you’re looking to replace a rickety, weathered, old deck this summer, here are five things to consider so that your new one lasts a lifetime.

Five Ways to Make Your Deck Last Longer

Code-Compliant

Depending on where you live, the size of the deck, and how high it is off the ground, you may or may not need a permit to build a deck. But even if your project doesn’t require a permit, you or your contractor should definitely follow the building code specs during construction.

The city of Markham has a free, downloadable guide (search for “Residential Decks: A Homeowner’s Guide” on their website markham.ca.) that covers the Ontario Building Code requirements, along with helpful diagrams showing how the parts come together.

Key items include the minimum height required for railings, the maximum gap allowed between the vertical pickets supporting the railing, and the maximum and minimum allowable height and depth of each stair tread.

Plus, no one wants to get themselves in the situation where a neighbour calls the city and you find out after it’s built that your new deck is too close to the property line.

Solid Foundation

Any structure, including a deck, is only as durable as its foundation. The footings that support the deck need to extend below the frost line – in southern Ontario that means at least 4′-deep.

The wood used for the framing should be pressure-treated (PT) to prevent rot and insect-damage. If you’re splurging on higher-end materials, such as cedar or composites for the deck surface, a properly designed deck will cover up and shield the green-hued PT from view.

Note that PT wood is corrosive to most screws and nails, so you need to use PT-approved hardware – look for an “ACQ-approved” label on the packaging. Also, keep in mind that the ends of any PT lumber that is cut will need to be treated on-site with preservative.

Composites

Composite deck boards are rot- and insect-resistant manufactured lumber that is made from a mix of recycled plastic and wood. When they first came out, some composites were plastic looking, excessively hot to the touch, and could even start to sag in the heat. Since then, the technology is much improved and there are a number of realistic-looking options available in a variety of colours and textures. Composite deck boards also come with warranties up to 25 years, protecting you against defects. If seasonal expansion and contraction causes a wooden deck board to start developing foot-stabbing splinters, you’ll have to foot the cost of replacing those boards.

Whatever material you choose for the deck boards, be sure to leave a gap between each to allow for seasonal expansion and contraction of the material and to allow rain and debris to fall through.

Aluminum and Glass Railings

Glass and aluminum railings offer a low-maintenance, splinter-proof, weather-resistant alternative to the standard wooden railing. Of course, most people choose this option for the unobstructed view that these products offer.

Maintenance

A deck is not a build-it-and-forget-it project. At least once a year, inspect components and wood for signs of rot, paying particular attention to key structural elements, such as railings, stairs, and the main support posts. You should also check and tighten any nuts and bolts used as fasteners. Periodically clear out any pine needles and other debris that gets stuck between the deck boards, as those will hold water against the wood, leading to rot.

Every year or so, you should scrub the deck with a cleaner specifically formulated for the type of deck boards you used. These products are applied with a broom or brush, and then washed off with a hose. Don’t use a pressure-washer as the intense spray can breakdown the wood fibres leading to rot, or even carve gouges in the surface. After scrubbing, you’ll want to seal the surface with a UV protectant.

Finally, change up the furniture floor plan on your deck periodically so that you don’t get sun discolouration in sections, and avoid using exterior carpets that get saturated and hold water against the deck boards.
