Measuring Casement Windows for Replacement

Replacing casement windows is a great way to improve the energy efficiency and aesthetics of your home. However, before you start shopping for new windows, it's essential to measure your existing casement windows accurately. This guide will walk you through the steps necessary to measure casement windows for replacement.

Gather the Necessary Tools

Before you begin measuring, make sure you have the following tools:

• Tape measure
• Paper and pen
• Level

Step 1: Measure the Width

Start by measuring the width of the window frame. Begin at the jamb on one side and measure across to the opposite jamb. It's essential to measure the width at three points: the top, middle, and bottom. Note down the smallest measurement as this will be the width you need to consider when selecting your replacement windows.

Step 2: Measure the Height

Next, measure the height of the window frame. Start from the sill and measure up to the head jamb. Like measuring the width, measure the height at three points: left, center, and right. Again, note down the smallest measurement since this will be the height you need to consider.

Step 3: Measure the Depth

Measure the depth of the window frame to determine the thickness of the replacement windows you'll need. Measure from the exterior trim to the interior trim. This measurement is crucial to ensure a proper fit for the new windows.

Step 4: Check for Squareness

Use a level to check if your current window frame is square. Place the level on the bottom sill and observe if it is perfectly level. Then, place the level vertically against each side jamb and check for plumb. If your current window frame is out of square, make a note of it as it might affect the installation process.

Step 5: Consider Additional Measurements

Depending on the replacement window style you choose, you might need to take additional measurements. For example, if you're opting for windows with muntins (grids), measure the width and height of the individual glass panes within each sash.

Conclusion

Accurate measurements are crucial when replacing casement windows. By following these steps and considering all the necessary measurements, you'll be well-prepared to find the perfect replacement windows for your home. Remember, when in doubt, consult with a professional for expert guidance.
