Signs That Decking Boards Need Replacing

Decking boards don’t last forever and are often prone to some nasty side effects even if they are well looked after. Look out for the following signs that your decking boards need replacing:

• Your decking boards are starting to rot
• You notice decking boards starting to split and warp
• Your decking boards have suffered damage from pests due to having rats underneath the decking.
• Your decking boards have suffered damage and have become unstable.

Even one or two of these signs provides great justification for replacing your decking boards, as they can cause the decking to become unstable which could compromise safety.

Importance of Replacing Deck Boards

Before we dive into the specifics, let’s talk about why replacing decking boards is so important. Your deck is more than just a pretty feature of your home; it’s an investment. Regular maintenance, including board replacement when necessary, can extend the life of your deck significantly.

When deck boards start to deteriorate, they can become a safety hazard. Loose, warped, or rotten boards can cause trips and falls, and in extreme cases, they might even collapse under weight. By replacing these boards promptly, you’re not only improving the appearance of your deck but also ensuring it remains safe for you and your loved ones to enjoy.

Moreover, replacing individual boards as needed is often more cost-effective than waiting until the entire deck requires replacement. It’s a proactive approach that can save you money in the long run.

Not only do deck boards whither overtime, but so does the substructure and frame of your deck. If the frame of your decking becomes unstable due to rot, warping or pest damage, a full replacement might be necessary.

Tools and Materials Needed

Before you begin, it’s essential to gather all the necessary tools and materials. Having everything at hand will make the process smoother and more efficient.

Essential Tools

To replace your deck boards effectively and safely, you’ll need:

• A pry bar
• A circular saw
• A drill with the appropriate drill bits
• A tape measure
• A pencil
• A pair of safety goggles and work gloves
• A hammer
• A level

Materials

As for materials, you’ll need:

• New deck boards (matching the size and type of your existing boards. Make sure to select the correct thickness of deck boards too)
• Deck screws (preferably stainless steel for durability) – you’ll also want some hidden fasteners too.
• Wood filler (if necessary)
• Exterior wood stain or sealant

When selecting your new deck boards, consider opting for a more durable option such as composite decking. Composite decking offers excellent durability and requires less maintenance than traditional wood, making it an increasingly popular choice among homeowners.

Step-by-Step Guide to Replacing Deck Boards

Now that you’ve got your tools and materials ready, it’s time to get started with the replacement process.

Step 1: Assess the Deck

Begin by thoroughly inspecting your deck. Identify all the boards that need replacing by looking for signs of rot, warping, splitting, and excessive wear. It’s a good idea to mark these boards with chalk or tape for easy reference.

While you’re at it, check the underlying structure of your deck, as this is also prone to damage and wear. If you notice any issues with the joists or support beams, it’s best to address these before replacing the deck boards by contacting a professional. If you decide to go with composite decking, composite joists provide a sturdy foundation to ensure your decking won’t move or collapse.

Step 2: Remove the Old Deck Boards

Before removing any deck boards, remove any furniture or obstacles from your deck. Then, begin removing the damaged boards. If your deck boards are nailed down, use the pry bar to carefully lift the board, working from one end to the other. For screwed-down boards, you’ll need to remove the screws first using a drill.

Take care not to damage the surrounding boards or the underlying structure as you work because this could lead to extra costs. If you’re planning to replace all the boards, start at one edge of the deck and work your way across.

Step 3: Prepare the Deck Frame

With the old boards removed, take a moment to inspect and clean the exposed frame. Remove any protruding nails or screws, and check for signs of rot or damage in the joists. If you find any issues, now is the time to address them.

It’s also a good opportunity to ensure the frame is level. Use your level to check, and make any necessary adjustments before proceeding.

Step 4: Cut and Fit New Deck Boards

Measure the space where you’ll be installing the new boards and cut them to size using your circular saw. Remember the old carpenter’s adage: measure twice, cut once! It’s always better to double-check your measurements to avoid waste.

When working with different types of materials for decking, be sure to follow the manufacturer’s guidelines for cutting composite decking. Some materials may require specific techniques or tools for the best results.

Step 5: Install New Deck Boards

Now it’s time to install your new deck boards. Start by positioning the board in place, ensuring it’s snug against the adjacent boards. Next, use your level to check that it’s even.

Pre-drill holes for your screws to prevent splitting, especially if you’re working with hardwood. Then, secure the board using your deck screws. Most experts recommend using two screws at each joist crossing for maximum stability.

Step 6: Finish and Seal

Once all your new boards are in place, you’ll want to protect them from the elements. If you’ve used wood boards, apply a coat of exterior wood stain or sealant according to the manufacturer’s instructions. This will help protect your new boards from moisture and UV damage.

For composite decking, follow the manufacturer’s recommendations for cleaning and deck maintenance to keep your deck looking its best for years to come.

Tips for a Successful Deck Board Replacement

Choosing the Right Materials

When selecting replacement boards, consider factors like durability, maintenance requirements, and aesthetics. While traditional wood decking has its charms, many homeowners are turning to composite decking for its longevity and low maintenance needs.

Maintaining Your Deck

Regular maintenance of your decking can significantly extend its lifespan. Clean your deck annually by hand, and re-seal or stain wood decking every few years. You can also jet wash your decking for better results, but this must be done properly to avoid damage. For composite decking, follow the manufacturer’s care instructions to keep it looking its best.

How to Prevent Future Damage to Your Deck

Replacing decking boards might not be a one-off job if they aren’t properly cared for and maintained for years to come. Many hard and soft wood decking boards need regular cleaning and maintenance, especially during the colder months.

We recommend staining and sealing your deck biannually for the best protection throughout the year. For even better protection, replacing wooden decking with composite decking boards is a good option. Composite decking offers the same look of wood without the maintenance and short lifespan. Plus, there are a variety of composite decking colours to choose from, creating an endless supply of design possibilities for your garden.

Final Thoughts

Replacing deck boards might seem like a long task, but so long as you’re equipped with the right preparation and approach, it’s a project that many homeowners can tackle successfully. Not only will you save money by doing it yourself, but you’ll also have the satisfaction of improving your outdoor living space with your own two hands.
