Step-by-Step Installation Guide
Step 1: Make the Opening Watertight
Start by ensuring that the opening where you will install the window is watertight. Use aluminum tape or a water seal gasket to seal the perimeter of the opening. Begin at the bottom sill, applying the tape both above and below, ensuring no gaps remain. Proceed to seal the sides, and make sure to create perfect corners by cutting and folding any excess material.
Step 2: Level the Opening
Using a bubble level, check that the bottom sill is level. If it’s not, adjust one side with a small shim until it is perfectly level.
Step 3: Place the Window in the Opening
Prepare the new window by bending the nailing flange to a 90-degree angle if it isn’t already. This ensures that when installed, the flange will flush with the wall. With assistance, lift the window into the frame, ensuring it fits snugly and that the shim remains in place.
Step 4: Nail the Window
Starting from the top, hammer a nail into the center hole of the nailing flange. Then, place nails in every other hole, checking that the window remains level as you work your way down. Once you confirm its level, continue nailing in the remaining holes.
Step 5: Additional Water Seal
To prevent any leakage, apply more gasket or aluminum tape over the top nailing flange. This extra layer helps ensure that water does not penetrate from above.
Step 6: Interior Installation
Next, build the casing for the window. Install all necessary window hardware, including the crank mechanism, screws, hinges, and locks.
Step 7: Finish Work
Once the window is securely installed, focus on finishing touches. Inside, hang the molding and paint the casing as needed. On the exterior, install a new sill and window frame, ensuring to caulk all openings to prevent leaks. Finally, replace any siding or shingles that were removed during the installation process. By following these steps, you can successfully replace and install casement windows, enhancing both the functionality and appearance of your home. If you encounter difficulties or prefer professional assistance, don’t hesitate to seek help.

Can I replace casement windows with double hung?

How to measure casement windows for replacement?
To measure casement windows for replacement accurately, follow these steps to ensure you get the right dimensions for your new windows.
Step-by-Step Measurement Guide
Gather Your Tools:
- Notepad and pen for recording measurements
- Safety glasses (optional)
Measure the Width:
Measure the width of the window at the center. Extend your tape measure horizontally from trim to trim. It’s advisable to measure at three different points (top, middle, and bottom) to account for any irregularities in the frame. Record the smallest measurement to ensure a proper fit.
Measure the Height:
Measure the height of the window from the top of the head jamb to the bottom of the sill. Again, take measurements at three points (left, center, and right) and note the smallest height to ensure accuracy.
Check for Depth (if necessary):
If you’re replacing the entire window frame, measure the depth of the window from the exterior trim to the interior trim. This measurement is crucial for ensuring that the new window fits well within the existing structure.
Double-Check Your Measurements:
After recording your measurements, it’s essential to double-check them. This step helps to avoid errors that could lead to purchasing the wrong size window.
What holds the casement window in place?
Hinges hold casement windows in place. These hinges are typically located along one side of the window frame and allow the panel to swing open or closed.
