Choosing the Best Decking Material

Build the deck that's right for you. Decks and fences add additional living space, beautify your yard and add value to your home. But before you go shopping for the materials to build your deck or fence, there are four things that need to be considered: price, aesthetic, lifestyle and maintenance.

Before starting any building project check with your municipal office for local building codes, regulations and zoning restrictions.

Pressure-Treated Wood Decking

The majority of decks built in Canada are constructed from pressure-treated wood because it's typically the most affordable option. Pressure treating lumber protects it against decay and termites for long-term protection of the wood when used in exterior application. However, pressure treating wood doesn't make it completely resistant to moisture, which means that you'll have to apply a water repellent to your deck on an annual basis in order to protect against moisture damage.

MicroPro Sienna® products are pressure treated with MicroPro® Micronized Copper Azole (MCA). MCA is the most advanced preservative technology available for treated wood used in residential application. MCA has been specially formulated for Canadian species and use and has pigment injected into it to give it a natural, brown colour.

Maintenance

Decks made of pressure-treated wood can last up to 40 years. Once your deck has completely dried, apply a clear sealant to help prevent splintering and discolouration caused by moisture.

To maintain your deck, wash it annually with a detergent to remove dirt, moss, algae and mould. A pressure washer is also a fast and easy way to clean your deck. Be sure to use the fan spray nozzle at low power to avoid damaging the wood.

Cedar Decking

Western Red Cedar possesses an oil preservative that makes it naturally resistant to decay and insect damage. Its beautiful grain, texture and colour make it one of the most aesthetically pleasing deck and fence materials. It’s lighter than pressure-treated wood, which makes it easier to manoeuvre and work with, but typically more expensive as well.

Maintenance

To maintain your cedar deck, wash it annually with a mild detergent and water. Never use a pressure washer on your cedar deck. Although cedar is durable, it's still a softwood and can be damaged by a pressure washer. Don’t forget to apply a finish to your cedar deck to keep it looking great.

Composite Decking

Composite decking is made from a combination of natural wood fibres and durable resin. Designed to resemble real wood, composite decking and fencing requires no painting or staining and won’t splinter, crack, warp or rot.

Veranda composite decking features realistic wood-grain patterns and is available in a large selection of colours. Backed by a 25-year limited warranty, you can have peace of mind knowing your investment in a composite deck is protected season after season.

Maintenance

Periodic washing with soap and water is necessary to remove surface dirt and chalk that accumulate on the surface. This will also prevent the build-up of pollen and debris that can cause mould and mildew growth. Pressure washers should be used for wetting and rinsing only and not to “blast off” soiling agents; attempting to do so can drive the dirt deeper into the material. Test on an inconspicuous area before washing the entire deck.
