(1) 2002 Detail of rooftop chimney’s siding, prior to work, and in progress
The siding is essentially particle board with a surface shell on the vertical face only. As manufactured, and inexplicably, the vulnerable bottom edge is not sealed, and the raw particle board soaks up moisture.

|
(2) Initial repair step
Unsound edge material was ground off. Subsequently elastic sealants and fillers were applied. Final top coats were acrylic enamel.

|
(3) Corner baton-siding juncture, prior to work, and finished
Defective caulking left the particle board core free to soak up moisture.
|
|
(4) Finished chimney
The unshielded structure’s exposure to weather is obvious.

(6) Window-siding junction, prior to work, and finished.

(9) Defective butt joint caulking, and its replacement
The original caulk bead was all to one side rather than centered over the joint. The core of the siding remained unsealed.
