4. Create Support for the Window:

Depending on the specific requirements of your wood window and the construction of your home, you may need to create additional support for the window. This can involve installing sill pans, adding blocking, or reinforcing the framing as necessary.

5. Check for Level and Plumb:

Using a level, ensure that the sill is level and the sides of the window opening are plumb. Make any necessary adjustments by adding or removing shims to ensure a level and plumb installation.

6. Secure the Window Opening:

Secure the window opening by installing wood screws through the sides of the window opening and into the framing. This will provide stability and prevent the window from shifting during the installation process.

Once the window opening is prepared and secure, you’re ready to move on to the next step: applying moisture barrier and flashing.

Step 4: Applying Moisture Barrier and Flashing

Applying moisture barrier and flashing is a crucial step in ensuring that your wood window is protected from water infiltration. Follow these steps to properly apply the necessary layers:

1. Start with the Moisture Barrier:

Apply a continuous layer of moisture barrier around the perimeter of the window opening. Ensure that the barrier extends beyond the edges of the opening to create a watertight seal. Use a caulk gun to apply the barrier in a consistent and even manner.

2. Overlap the Flashing:

Place the flashing tape or metal drip cap over the moisture barrier, overlapping the edges for maximum protection. Make sure the flashing extends over the top flashing, if present, and extends down the sides of the window opening.

3. Seal the Edges:

Use a putty knife or your fingers to press the edges of the flashing firmly against the surface, creating a secure bond. Pay extra attention to the corners and seams, ensuring that they are well-sealed to prevent any water penetration.

4. Cut and Fold the Flashing:

If necessary, cut and fold the flashing to fit around the corners and angles of the window opening. Ensure that the flashing is smooth and tight against the surface, with no wrinkles or gaps that could compromise its effectiveness.

5. Inspect the Installation:

Thoroughly inspect the moisture barrier and flashing installation. Check for any air bubbles, gaps, or areas that may require additional sealing. Address any issues before proceeding to the next step.

6. Perform a Water Test:

To ensure the moisture barrier and flashing are effectively preventing water infiltration, perform a water test. Spray water onto the window and surrounding area, paying attention to the flashing and barrier. Check for any signs of water penetration or leaks.

Once you’ve successfully applied the moisture barrier and flashing, you’re ready to move on to the next step: installing the wood window.

Step 5: Installing the Window

Now that the window opening is prepared and protected with moisture barrier and flashing, it’s time to install your wood window. Follow these steps to ensure a secure and proper installation:
