So you’ve signed a contract with a window company and picked out the perfect modern windows for your house. The next step in the process is probably the most crucial: the window measurement.

Remember, regardless of the skills of installers, or how good the quality of the product you bought is, if they are not measured properly, vinyl windows will NOT provide the maximum energy efficiency they’re supposed to.

Regardless how big or small your replacement project is, it is important to get the new window to fit as closely as possible to the original opening. The measurement is also a time when the installer can assess any existing problems, and map out a plan of action for the day of the installation.

Window Measurement: Step-by-step

The installer begins by measuring the width of the wall to determine the size of the jamb extension.

The width of the window is then measured in several places. The smallest measurement becomes the width of the new window.

The height of the window is measured. This will determine both the height of the window and the size of the brickmould. The difference between the outside measurement and inside measurement becomes the dimension for the new brickmould.

For brick to brick installations, the installer measures windows from the outside edge of the frame to the other edge. An inch is subtracted from each dimension to accommodate the new brickmould.

Remember, ensuring your custom windows are measured properly goes a long way toward saving yourself from headaches on the date of the installation. Be sure to verify all the materials, options, and parts have been taken into consideration at the time of measurement.
