Pebble Dash Stucco chimney
Takoma Park area, Washington, DC
How we did it !
The accusing finger points to the source of the leak.
The old step flashing had pulled away from the
chimney. The flashing on the front was stuck on with caulk and had separated creating a water funnel.
There was no counter flashing on the sides.
Stucco is pulled of deteriorated bricks.
Bricks are filled and stabilized with Flex-con
in the mortar.
Fortunately the back side, or the cricket side flashing was in good shape. The flashing is copper. Most old steel flashing we find has
rusted out.
We overlapped the edge of the flashing with mortar.Fortunately the back side, or the cricket side flashing was in good shape. The flashing is copper. Most old steel flashing we find has

The left over counter flashing from Reston was used to flash the base of the chimney and sealed. The flashing is then overlapped with plaster stop (casing bead).
The bricks are roughed up with a chipping hammer and a scratch coat applied to the whole chimney.
Our method of half and half flex-con with water is used in the mortar. The flex-con here is used for a bonding admixture, but has a side benefit of making the mortar less porous.
The top is done with white Portland and sand using a sand float finish.
We embedded two dollar coins for a time capsule.
Pebble mix is thrown on.
We used weep grounds at the bottom for drainage.
We re-did the front entrance walls also.
I was saddened to learn of Bernard Shaw's death. This is one of his houses. We worked on his other house in Takoma Park, MD.
If you aren't old enough to remember Bernard Shaw, he was the news anchor on CNN back when CNN was the news, up until
2001. Bernie was super hospitable and was a big influence on me.
