The new window is set in place.	Our installers use two beads of 50-year sealant to waterproof the windows, one between the old aluminum frame and the inside of the new window flange; and one along the exterior edge of the flange (shown here).	We use long screws to hold the new window firmly in place by going into the studs in the wall. We also use foam to insulate the space between the new window and the drywall.

Flat vinyl trim is applied to the interior of the window, covering the space between the new window and the drywall.

This old wood window looks pretty good, but does not insulate or operate well.	The wood stops are removed so that the sash (internal part of window that holds glass) can be removed. Depending on how the original windows were made, we may remove either the interior stops or the exterior stops.	The sash are removed leaving a large rectangular opening.
A double bead of 50-year sealant is used to waterproof the windows.	The new window is set in place. It sits inside the opening of the old wood window.	Foam insulation is used to be sure the window does not rattle or leak air around the edges.

New wood trim is used around the perimeter of the new window to complete the installation. The wood trim will need to be painted by others.
