Wood Windows

Lake Oswego, just south of the PCC Sylvania Campus.

The left side of this house, which is also the south facing side of the house bears the brunt of the weather. And as you can see, the architecture provides very little protection for our client’s wood-sash windows.

If you enlarge some of these photos, you may be able to make out telltale signs of water-damaged wood window components.

Obviously, some are more obvious than others.

While some components may only look like the paint has lost its adhesion to the wood, those of us who inspect wood windows for a living can usually tell that the “wrinkles” in the paint mean that the wood has shrunk due to rot.

As so frequently happens with this type of work, what was initially approached as an exterior trim and sill component repair project has translated into “change-order” work. The removal of certain components has exposed further damage that was previously covered, such as the edge of the jamb-leg (shown above) that had been covered by the brick-moulding.

This photo shows that the removal of the water-damaged “sub-sill” exposed the “main-sill” and more jamb-leg damage, necessitating the temporary removal of the double-hung sash.

Fortunately, on this project, the weather has turned quite accommodating for work that involves opening up exterior walls.

This shot, somewhat obscured by the shadows, shows one of our technicians installing replacement materials for the window-jamb.

And just before we replace the exterior brick-moulding trim as this day nears its end, the exposed sheathing surfaces are coated with a self-adhesive flashing-membrane that we have tied into the exterior walls moisture-barrier. The particular product that we have used here is called Grace Vycor Plus.
