WINDOW Replacement and Installation

1. Tools Needed

• Tape measure

• Level (optional)

• Pen and paper for recording measurements

2. Measure the Width

• Measure from inside the window frame. Begin at the top of the window opening, then measure to the bottom.

• Take 3 measurements: one at the top, middle, and bottom.

• Record the smallest measurement (this ensures the window will fit).

• Double-check measurements in case of any irregularities.

3. Measure the Height

• Measure the height of the window from inside the frame, starting from the windowsill to the top of the frame.

• Take 3 measurements: one on the left side, one in the middle, and one on the right side.

• Again, use the smallest measurement for accuracy.

4. Measure the Depth

• This is to check the depth of the window frame, which helps determine if the window will sit properly.

• Measure from the outer edge of the frame to the inner edge, ensuring the depth is consistent across the entire frame.

5. Check for Square

• To ensure the window is square (so the new window sits properly), measure diagonally from corner to corner in both directions.

• The two diagonal measurements should be the same. If they’re not, the window frame may be out of square, and additional adjustments may be needed.

6. Consider Additional Factors

• If the window has trim, measure from outside the trim if replacing the entire window.

• If the trim will stay, measure from inside the trim to avoid a bad fit.

• If there is any old caulk or other materials, remove them to get an accurate measurement.

7. Double-Check Everything

• Always measure twice to be sure of the correct dimensions.

The cost of window installation can widely vary depending on several factors. The cost of the window is from a standard double-hung window to fully customized pieces from several materials. From this, there are usually additional costs from removing the old window, insulation, caulking, and trim or frame adjustments.
