• Installation tools such as electric drills and screw guns
• Measuring and marking tools such as a tape measure and a carpenter’s pencil

Selection of Suitable Replacement Decking Boards

There are several factors to consider when choosing replacement boards. The first is the type of material; wood deck boards are relatively inexpensive. However, the problem with it is that it may need to be replaced again after some time. If your deck is a composite deck, you can simply purchase the same type of deck boards for replacement. COOWIN composite decking boards are durable and will last for a long time after replacement.

As a rule, you need to buy an additional 10% of the quantity to cover cutting mistakes and future repairs. Experienced builders will place the new boards ahead of time to acclimate them to the temperature and humidity of the installation environment. This will prevent excessive expansion and contraction of the deck boards.

Cleaning The Deck

Before you can officially begin, you will need to clean the deck. Make sure that the area to be replaced has enough space for the work. If your deck requires extensive replacement of deck boards, remove all items on the deck, such as furniture and decorations. This will ensure safety and will not damage the furniture.

Step-By-Step Procedure for Replacing Deck Boards

So, how do you replace deck boards? You can follow the steps below.

Remove The Damaged Deck

Locate the boards on the deck that need to be replaced. If you don’t want to remove the entire deck board, use a pencil to mark the location of the cut. The cut should be at least one joist spacing from the end of the deck board next to it. Use a pencil and ruler to mark the cut line. Then use a circular saw to cut the damaged deck boards so they are flush with the joists.

Plastic spacers can be inserted between adjacent boards to protect the surface while cutting. In addition, the jigsaw can be switched to complete the cut when close to an obstacle. If it is necessary to remove fixings in the appropriate locations, they can be removed starting from the center of the joist. Screws that are difficult to remove can be pulled out using cat’s jaw pliers or just cut off.

Inspecting and Reinforcing The Deck Structure

After removing the deck boards, you will first need to thoroughly inspect the exposed joists. First, test the joists for stiffness with a screwdriver to make sure they are not rotted. Then check for rusted or missing metal connectors.

If the joists are rotted or damaged, they need to be repaired and reinforced. This is because damaged joists not only affect the lifespan of the deck but also pose a safety risk.

Measure and Cut New Deck Boards

Measure and cut the new deck boards to the corresponding size. Take care to allow for a suitable expansion gap according to the deck material. In addition, using a fine-toothed saw blade when cutting composite deck boards will avoid burrs.

Installing The New Deck Boards

Install the new deck boards piece by piece. Spacers can be used during installation to ensure that adjacent boards are spaced consistently. When using screws, keep the screws at least 3/4 inch from the edge of the boards. Also, avoid weight-bearing for 24 hours after installation. If you are unsure how to do this, you can read installation guides from manufacturers such as Trex, COOWIN, etc.

Staining and Sealing

If you have a wood deck, you may also need to stain and seal it after installation. Select the appropriate sealer and stain, then use a quality brush to work in the direction of the wood grain. Pay attention to the ambient temperature before and after construction, and waterproof the area. Of course, if you are using composite decking materials, staining and sealing will not be necessary.

How do I Maintain My Deck After Replacing Deck Boards?

Regular maintenance can extend the lifespan of your deck. For newly replaced deck boards, it is even more important to inspect and clean them in a timely manner. Special deck cleaner or soapy water can be used for cleaning. Pay attention to removing debris from the seams to prevent the decking boards from rotting again. Every six months, the railing structure and screws should be checked for safety to prevent danger.
