When inspecting the exterior of the building, look for the following:
Landscape plants within 18 inches of exterior walls.
Gutters & down sputs everywhere in good working order.
Any wood within 12 inches of (or especially in contact with ) ground.
Wood piles at least 18 inches away from house.
Look for general patterns of fading of the finish.
Look more carefully at areas that are most exposed to weather.
* South and west walls usually get more sun exposure.
* Walls facing prevailing winds are exposed to more rain.
* Look for patterns of weathering. Fading of the finish.
* Water staining on exposed log ends.
* Water staining on exposed walls.
* Make sure that no sprinkler directs water at the wall. Including water patterns on windy days!
Get up close and personal
Dust, pollens, etc. on upward facing portion of logs.
* Clean this stuff off with water or mild cleaning solutions.
Inspect for any cracking, peeling or blistering of finish.
Check water repellent quality of finish.
* Spray or splash water on walls, then look for it to "bead".
Inspect for presence of molds or mildews.
* On top of finish (can it be washed off?)
* Underneath finish.
Upward facing checks (1/4 inch or wider) should be sealed.
* Use Check Mate
Carefully inspect logs for signs of moisture.
* Discolored wood.
* Softened wood. Pay special attention to all logs and ends
extending to or beyond roof overhangs. Inspect integrity of all sealant joinery
(Perma-Chink, Energy Seal, QSL, Check Mate) at log-log interfaces, windows,
doors, checks, roof lines or any potential air or water intrusion points.
