Moving right along onto another chimney restoration!
This chimney has a top course of brick that is corbeled out with a raised concrete cap (which by now you may know I loathe for reasons such as increased water deterioration etc…).
So to be honest (and all of this I explain to every customer in detail so they’re aware of why their chimney has started to deteriorate) the only reason we have issues on this chimney such as sprawling brick, cracked brick, popped out mortar joints, flashing damage and brick displacement is due to no drip edge.
Surprisingly, the finished concrete on top of the chimney is in excellent condition, no micro cracks from the concrete shrinking or gaps in-between the flues. So to increase longevity, I am surface grinding the entire cap to increase water runoff due to some flat areas of the concrete starting to pit from sustained standing water. A full chimney repointing will be done, brick extraction and replacement of any and all cracked bricks, flashing tear out and replacement and lastly I will be cutting a drip edge into the underside of the first course of corbeled out brick with a micro blade as I have just enough room to install one due to the amount of room available to be able to do so.
I have already smoothed out the top concrete area with a surface grinder and am done with grinding out all of the mortar joints and extracting the brick! I will be repointing the chimney today with a lighter N-Type mortar, a hint of “light Buff” mortar dye and adding an acrylic bonding agent additive to the mortar to increase overall strength of the new masonry bond.
