Defect / Water Leak Remediation

An older Lake Oswego home with board and batten siding, single-pane wood windows and lath & plaster interior walls.

Our client informs us that water is showing up around the interior side of this front facing living room window assembly.

Inspecting the interior side, we discover that the location of the water seems to correlate with the vertical mull-post between window sash. Upon checking the other mull-post, we discover a similar condition.

This pattern would suggest water penetration from above, so we step back outside and take a look above.

This is one of about four or five vertical splits in the siding boards that have been channeling moisture down upon the top of the window header-jamb when the wind blows the rain just right.

And so, upon acceptance of our proposal, we return and remove the board and batten siding above this window assembly.

This photo typifies one of our ad hoc shops we set up on site to facilitate our repairs. If you click on the photo, it will enlarge a bit.

Tim & Juan are hard at it, reinstalling the siding after properly flashing the top of the window and applying the moisture-barrier.

The finished product. Better than new.

We repaired the interior wall surfaces as well.
