The time you spend on your deck will be appreciated even more when you know your deck is in good condition and your deck’s structure – or foundation is strong. According to the NADRA (North American Deck and Railing Association), approximately half of the decks in the country require inspection, possible repair, and potentially replacement.
That may seem like a high estimate, but when you think about the decks that could use some maintenance and care, it’s easy to understand why NADRA states this fact. If you’re worried about your deck or its upkeep, check out some guidelines to help you assess your deck’s condition.
Surface, Railings, and Steps
Checking on your deck boards, railings, and stairs, if you have any, is of utmost importance. It’s pretty easy to identify areas of concern, such as discoloration, mold, weak spots, and loose boards or railings that require repair. Take immediate note and address the issue promptly. A loose deck railing can easily become unfastened and pose a hazard, even a deadly one.
Wood that is lighter or darker than usual can indicate the presence of rot. Also, check for insects, such as termites or other pests, as well as wasps. Wasps will build nests under and around decks. Another thing you can do is check your fasteners for loose or rusted screws. Repair that right away.
Substructure and Support
Moving on to what you can’t see is the next step. Whether you have a wood or composite deck, the substructure will be made of wood. The deck substructure consists of joists that run horizontally beneath the deck boards and vertical beams that support the joists.
When constructing a deck, it is essential to check the building codes and utilities (before digging) and ensure the deck’s footings are firmly secured. Digging below the frost line is necessary so your deck has the most solid footing and no pier movement. A common mistake is not digging deep enough, which can cause problems when the ground expands due to frost.
Cleaning and Maintenance
Clean both composite and wooden decks about every six months. A homemade or commercial cleaning solution will work if you have a Trex deck. Sweep your deck first, then use a putty knife or similar tool to remove debris, such as leaves, pine needles, and small twigs, from the spaces between your deck boards.
To clean, use a bristled scrub brush or a power washer adjusted to no more than 1500 p.s.i. Setting the pressure too high could scar the composite. If you go the power washer route, then spray at an angle. Ensure your spray nozzle is positioned approximately two feet above the deck surface, and apply the solution in a slow, sweeping back-and-forth motion. Rinse completely and allow to dry thoroughly.
If you have a wooden deck, consider sealing it. A quality sealant will help protect your deck from moisture damage, rot, and the harsh effects of UV rays. Sealing will extend the life of your deck and keep it looking good. Additionally, sealants can come in different subtle colors or be translucent. Generally speaking, sealants will keep your wood deck protected for one to two years.
Waterproofing and Flashing Tape
Let’s not forget about the benefits of using deck flashing tape. Deck flashing tape will cover your joists and fasteners by keeping moisture out of essential areas that support your deck. Flashing tape comes in three types: acrylic, butyl, and silicone.
Butyl tape is the best deck flashing tape for protection, as it is the easiest to work with, tolerates a wide range of temperatures, and provides a watertight seal.
Diverting of Water
Water can damage your deck and its structure in two main ways. One is water seeping through the surface boards and affecting the underneath. The second way is for moisture to get trapped between your deck and your house.
When moisture stays trapped with little ventilation, it is a recipe for mildew and wood rot. This makes it essential to divert water from your deck and its underside. Fortunately, there are several things you can do. An under-deck drainage system is worth considering, as well as the deck flashing tape mentioned earlier. Also, redirecting water away from your deck and patio will help keep this area drier. If water tends to run off your house towards your deck, consider installing a drainage ditch, such as a French drain, to divert the water.
Upkeep
When thinking about all the methods to prevent damage to your deck, don’t forget one of the easiest things you can do to stop these from happening. One of the best methods to preserve your deck and its support structure is to clean it regularly, inspect it for possible problem spots, and keep out insect invaders.
Protecting your deck is similar to tending to a garden in that you’re helping the deck survive, look good, and stay strong. It’s a commitment and certainly one that will pay off.
In Conclusion
If you want years of fun, memories, and many good experiences on your deck, ensure your foundation and surface are clean and ready to withstand the elements.
