Cedar Deck Installation: Common Mistakes To Avoid
Though redwood, pine, and ipe are commonly used for decking, none of them quite match the natural beauty and durability of cedar. Cedar’s beautiful straight grain pattern with intermittent knots and waves along with its rich woody color make it a sight to behold. Not to mention its resistance to rot and insects adds to its appeal.
However, cedar deck boards, if not properly installed can be robbed of the benefits they bring. Improper installation can considerably shorten their lifespan while ruining the aesthetics of a good deck. To ensure a cedar deck upholds its durability and attractiveness for a long time, it’s best to avoid the following installation mistakes.
1. Not letting the wood acclimate
Just like most other natural woods, cedar also releases and absorbs moisture depending on the climate it is in. Hence, it’s best to avoid installing cedar deck boards immediately after purchase. Since the likelihood of them shrinking or expanding post-installation is high, the boards might warp or leave gaps.
The best solution to this problem is to let the boards adapt to the local climate for at least 5 to 7 days before they need to be installed. It is best to store them in a dry and well-ventilated above ground so proper air circulation can be maintained.
2. Leaving the ends of boards unsealed
Finding the best cedar deck boards in the Niagara region is a great start, but sealing the cut ends is essential to prevent premature decay. Unsealed ends absorb moisture quickly, making them more susceptible to deterioration.
However, the application of a high-quality end-grain sealer just after cutting the board is a great way to combat this problem. Sealers prevent moisture from being absorbed, thus prolonging the life of the cedar boards.
3. Choosing the wrong fasteners
From damage and rust stains to wood discoloration, selecting the wrong nuts and bolts to fasten cedar deck boards can have unpleasant consequences. Since cedar contains natural tannins, it is prone to corrosion when it comes in contact with certain metals.
An easy fix is to exclusively use screws that are compatible with cedar. Hot-dipped galvanized, stainless steel, and coated deck screws are a great option as they are resistant to rust as well as prevent staining.
4. Improper board spacing
As mentioned before, cedar has the tendency to expand and contract as humidity levels change. Buckling might arise if the boards are too close together. Similarly, if they’re too far apart, the wide gaps created may adversely impact stability.
The best way to ensure spacing issues don’t arise is to maintain a consistent gap of ¼-inch to ⅜-inch between boards so that the wood gets enough space to expand and contract without affecting the stability of the structure. Spacers and decking jigs can also be used to maintain even spacing.
5. Decking too close to the ground
Installing cedar boards too close to the ground restricts airflow. Over time, this can lead to moisture build-up, which can further cause issues such as mold and rot.
This issue can be prevented by installing cedar boards 12 to 18 inches above ground. However, if there is no option but to install a low-level deck, using a vapor barrier is a must so that proper drainage underneath it can be maintained.
6. Not pre-drilling screw holes
Soft and prone to splitting, cedar can get easily damaged if screw holes are directly driven into the board. Especially along the edges.
Pre-drilling screw holes is a safe and effective way to prevent damage. It can also speed up the fastening process, ensuring a tight and stable joint without giving rise to issues such as splitting.
