We were recently on another tuck-point job in Willamette county and during this one, we tuck-pointed this chimney and applied Tamoseal to its crown.
In the before photos above you can see evidence of deterioration in many of the mortar joints. You can also see cosmetic stains on the brick and the flashing. This staining came from a raincap that was not made of stainless steel and had thus rusted over time. In the video below we explain the tuck-pointing and tamosealing process.
