If your deck is starting to show signs of wear or damage, it may be time to replace some of the boards. Also known as decking, common signs of damage include rotting, splitting, or warping of the wood. Each of these signs are unsightly and potentially unsafe if left unfixed. That is why it is important to have a plan to replace damaged deck boards as soon as possible. At Country Lumber, they know that it can be difficult to determine where to start when replacing deck boards. That is why their team of experts has created a guide outlining how to replace deck boards safely and effectively.

Steps for Replacing Deck Boards

When replacing deck boards, it is important to know the whole process before starting the job. This will ensure that the job is completed smoothly and in less time. To replace your decking, ensure that you have the required tools, then follow these steps:

1. Mark the Damaged Boards

Examine the deck and mark the locations of the damaged boards. Measure the portions of the board that will be removed to ensure that you are cutting the proper length for replacement decking. Ensure that these new pieces of lumber are supported at each end and by one joist.

2. Remove the Damaged Boards

Remove all nails or screws from the damaged boards or cut the damaged portions away from existing boards.

3. Seal any Joist Rot

Check the spaces under the removed decking for any rot. The lumber under the decking is known as the joist. If there is any rot on the joist, remove it and apply two coats of clear sealer to protect it.

4. Reinforce the Joist

After sealing the joist, it is recommended to reinforce it with another joist. Position the new joist tightly against the existing one and attach it with industrial nails or screws.

5. Secure Reinforcing Joist

Attach the reinforcing joist to the ledger and header joist. This will ensure that it remains secure when adding new decking.

6. Measure and Cut the new Decking

Use the measurements from the removed pieces of decking to cut new pieces. This new decking should fit snugly in the open space. If there is any cupping, position the decking with the convex/crowned side facing up.

7. Finish the Wood

Stain or finish the wood to match your existing finish.

8. Install the new Decking

After the finish is set, install the new boards with galvanized screws or nails. Ensure that the replacement decking matches the size of the old boards.

Following these steps will ensure the safe replacement of damaged decking. For more information on decking or other lumber products, please reach out to the team at Country Lumber. They can be reached at 604-533-4447 or through their online contact form.
