Miscellaneous Repairs

One of the many top-shelf villas that dot the Washington shoreline of the Columbia River.

Southeast facing Marvin non-clad wood casement windows with zero overhang. Need I tell you what the problem is?

Well the house isn’t old enough for the windows to be water-damaged yet, but give it time. No…the particular problem at this point has to do with the inherent characteristic I discuss frequently regarding casement windows in high wind scenarios with little or no overhang.

Unlike most other window function configurations, the “casement window” usually consists of an exposed exterior reveal between the sash & the jamb. You can see the consequences in the above photo. Those are water spots on the bottom of the large horizontal mull-post.

Even if this exterior wall consisted of a substantial eve (overhang), the prevailing winds along the river here are significantly influenced by the world famous wind-turbine known as the Columbia Gorge, despite what some folks were telling me to contrary about this…

…piece of property.
Anybody’s product would be sorely tested in these conditions…it is nothing unique to Marvin windows.

So we removed the top four sash from the jambs & provided significant aftermarket waterproofing products & techniques we’ve developed over the years to the seams and joints between the various jamb components to stop the water from…

…finding its way down through the horizontal mull-post directly beneath them. As long as architects continue to design homes with walls that lack significant protection from the elements while specifying wood windows like this in…

…locations like this…our company will stay busy trying to plug the holes and repairing and or modifying the wood window assemblies.

Our technician Conan is shown here refastening the interior mull-post cover.

And then he puts the finishing touches to the exterior after reinstalling the sash.
Please note: Although “sill-pans” would have kept the water from getting to the interior, you still don’t want water frequently accessing the joints of a wood window jamb.
