A common method of installation in this area by some contractors. Used to minimize labor costs, some materials and allows the contractor to install large quantities of windows in a shorter period of time. This will obviously reflect in a lower priced bid.

Windows are basically installed from the exterior without the windows flashing. Simply screwed in and caulked. There will be no shims to support the heavy glass units in the frame and no insulation.

"Over-Projection" voids the warranty on most, if not all manufacturers windows. This is generally not a problem as long as the contractor is still in business, since they will more than likely be honoring the warranty personally. This becomes more of a problem for the homeowner if the contractor is no longer in business.

Zoom in and pay close attention to the vertical line on the side of the window. This line usually indicates the center of the window. This line is required to be behind the siding and not exposed as seen above. We are not completely sure how these windows were actually attached.

NOTE: There are times when over projection is required. Examples would be where there are tile surrounds, sheet rock and the customer does not want to go to the expense of new interior casings or the customer simply does not want their interior casings removed (generally because of paint). If a contractor is performing this method of installation, placement of Z-flashing is very critical to minimize leaks.
