What Is a New-Construction Window?

As the name suggests, new-construction windows are intended for use in new construction.

What Is a Remodel Window?

Remodel windows are designed to fit inside the hole left behind by a previously installed window.

While you may gain a slightly larger window, it simply isn’t worth the added time.

Repeat this process to measure the width.

ensure you measure the full height of the frame, past the stop moulding that surrounds the window.

Carefully remove these and fill any voids left behind with loose fiber insulation.

Fill any holes in the surface and replace any damaged materials.

Inspect the exterior stop moulding, also called the blind stop, to ensure it isn’t damaged.

Manipulate the shims to ensure the window sits level and plumb.

If not installed both level and plumb, the window will not open and close properly after installation.

Adjust the shims if necessary.

Cut off the excess shims with an oscillating multitool or utility knife.

Reinstall the interior stop moulding with finish nails.

Once dry, paint the moulding.
