Something to Consider for ALL Wood Joints

While all joints are assembled a little differently, there are a few critical steps that should be followed when installing every piece of wood to ensure the cleanliness of the joint, and most importantly, the longevity of the wood. Before the wood is installed on the house, it is paramount that your contractor, or you, for the brave DIYers, abide by the following steps:

• Dry the Wood: A great way to ensure that wood will remain stable and damage-free is by ensuring that the wood you are installing is dry. Using a moisture meter, ensure that the wood has a moisture content of less than 12%. If your wood has a greater percentage, allow the wood to dry in the sun or use a heat gun to dry the edges. Continue to dry the wood until it has a moisture content of less than 12%.
• Primer: Prime all exposed wood grain. Anywhere that the wood has been cut cross grain, or anywhere that the wood will be touching another surface, such as another piece of wood, a piece of flashing, or the side of the wood that will be touching the house, must be primed. Priming the wood prior to installing it against another surface will minimize the amount of water that can rest on the board.
• Paint: Primer isn’t all you need to protect the wood. Primer is designed to help paint adhere to the wood, but isn’t designed to create a watertight seal. Apply a water resistant coating in the same areas that require primer.
• Caulk: The final step to ensuring that your joint will remain sealed for as long as possible is to caulk the joint. To guarantee that your joint has a fun seal with no air bubbles or pockets for water to rest in, apply a thick pool of caulk to the board minutes before installation. When installing the wood, press the wood together at the joint, and wipe away any excess caulk that squeezes out of the sides. This creates an airtight seal.

Follow these steps for every joint and you will have a joint that is designed to last.

The Joints that Hold Your Home Together

Wood joints are not something we think about often but head outside and look around your home, you will be surprised to see so many pieces of wood trim. Here are a few of the most common ones:

• Fascia Joints: Fascia boards are crucial for protecting the roof and interior from moisture. Miter joints are often used at the joints.
• Window Frames & Door Frames: Window frames and door frames are vital to prevent water infiltration and maintain insulation. Lap joints and miter joints are commonly employed here for their strength and simplicity. Ensure that there is proper flashing on the top piece of trim.
• Belly Bands: Belly bands are decorative trim that helps to break up the facade and provide a visual transition between different materials. These joints need to be tight and well-sealed, often using a simple butt joint reinforced with both flashing and counter flashing.
• Corner Boards: Corner boards shield the corners of your siding from weather and wear. Here, the joints need to be robust and well-crafted. Typically, a miter joint is used to provide a larger surface area for adhesion, enhancing both the joint’s strength and its resistance to moisture.
