Proper Deck Maintenance Is Essential to Long-Term Enjoyment

Would you go five years without washing your car? If you want it looking good and staying in tip-top shape, probably not. How about your deck? Just like that car, your deck requires periodic TLC to keep it looking good and to increase its life expectancy. Fortunately, maintaining your deck can be as easy as that car wash.

With spring just around the corner for Halifax, Nova Scotia, now is the time to start thinking about getting your outdoor space in shape for the coming season.

Annual maintenance of any deck should begin with an overall inspection of fasteners. Over time, the expansion and contraction of exterior wood due to moisture can cause hardware to loosen or pull away. This process causes “nail pops” in the floor. You can simply pound most nails back in. You may also want to consider replacing them with screws. And don’t forget to check under the deck for any loose nuts or corroded hangers.


Pressure-Treated – Pressure-treated lumber is designed to last for a very long time. In fact, most manufactures of treated wood give a lifetime warranty against rot and insect infestation. However, long-term exposure to the elements can have a detrimental effect on the look of your pressure treated deck. Begin by sweeping the deck to eliminate the big debris. Next use a cleaning solution and stiff-bristle brush to work out the ground-in dirt. (A simple solution of water and dishwashing detergent works well.) If the deck has “grayed out” substantially, you may want to consider a specialized deck cleaner, which you will find at most home improvement stores. For really extreme cases, you can even rent a power washer – but be careful because these machines can damage the wood fibers. Finally, apply a penetrating sealant with UV stabilizers to help preserve all that hard work.


Cedar & Redwood – Unlike pressure-treated wood, cedar and redwood have naturally occurring chemicals that make them resistant to rot and insect decay. Still, lack of added protection and maintenance will greatly reduce the life expectancy of these materials. Follow the same guidelines for cleaning and sealing as you would for treated material, but expect to seal it on a yearly basis instead of every other year.


Tropical Hardwoods – Tropical hardwoods such as IPE, also have naturally occurring chemicals that make them resistant to rot and insect infestation. The density, or hardness, of these materials also increases their longevity. For most people, the decision with tropical hardwood is whether to let it “gray-out” over time. If you choose to “go gray”, a simple cleaning once a year is fine. If you wish to maintain the dark color, you will have to apply special hardwood sealers.


Composites – Most composites are manufactured with some type of plastics, reducing or even eliminating any risk of rot and or insect infestation. Many also have UV stabilizers to help lessen any color changes. This material is still sitting outside however, so dirt and mildew will find its way onto the deck. A simple yearly cleaning with soap and water will keep your deck looking its best.

If you prefer to keep your hands clean, you can hire professional companies to perform these maintenance tasks for you.
