Walls and windows
How flashing, drainage planes, joints and cold surfaces create visible wall and window symptoms.
Learn the concept, then apply the field method.
The collection alternates between building-science explanation and bounded homeowner observation. It does not turn one clue into a diagnosis.
Window flashing and sill pans: what it means in a house
Windows need layered flashing that drains incidental water outward even when outer sealant ages.

A practical method for observing, comparing and documenting window flashing and sill pans without turning one clue into a diagnosis.

Cladding is rarely the only water barrier; hidden layers must collect and drain water that passes the exterior surface.

A practical method for observing, comparing and documenting drainage planes behind cladding without turning one clue into a diagnosis.

Sealant must stretch, adhere to two sides and accommodate movement; a surface bead cannot repair a failed joint design.

A practical method for observing, comparing and documenting sealant joints and movement without turning one clue into a diagnosis.

Condensation at the room-side edge, between panes and on exterior glass represent different mechanisms.

Blisters can result from moisture, poor adhesion, incompatible coatings or heat; the bubble itself is not a source diagnosis.

House symptoms often cross systems. Keep competing explanations visible, preserve the baseline and stop where access, electricity, combustion, structure, contamination or hazardous materials create a professional boundary.
