Brick and mortar facts our masons share in Lake Underhill
Three points our masons in Lake Underhill explain before any mortar is cut out.
Why head joints need hand work
The short vertical joints between bricks are called head joints. Brick industry guidance warns that a grinder cannot remove the full depth of mortar from them without damaging the adjacent brick, so the remaining mortar has to come out with a chisel.
It is slower, and it is the difference between a clean repair and chipped brick corners along every joint. We budget the time for it in the estimate instead of rushing the step that shows the most.
The mortar type recommended for chimneys
A table of mortar recommendations by use appears in Technical Note 8B. For exterior, above-grade parapets and chimneys, it recommends Type N, with Type S as the alternate.
That is a starting point, not a rule that overrides the existing masonry. For repointing, compatibility with the brick and mortar already there comes first, and softer mortar may be the right choice on older work. We explain which applies to your chimney. Your estimate names the proposed type and says why it was chosen over the alternative.
Cleaning brick without damaging it
Cleaning can harm brick when it is done badly. Brick industry guidance warns that too little prewetting, too little rinsing or strong chemical concentrations can cause new staining, etch mortar joints and increase moisture penetration.
When cleaning is part of a masonry repair, we use products made for brickwork, follow their instructions and test a small area first. A harsh cleaner can do more visible harm in an afternoon than years of weather.
Veneer ties and retrofit anchors
Brick veneer is held to the structure behind it by ties. Where ties are too few or have failed, the veneer can bulge or crack. Technical Note 46 describes retrofit anchors installed through the mortar joints for that problem.
It also stresses that each anchor product has its own methods and limits, and that the manufacturer should be consulted. When veneer movement suggests failed ties, we explain the options, including when an engineer should look first.

Chimney masonry questions from Lake Underhill
Our family-owned crew in Lake Underhill answers what homeowners ask about chimney brick.
Why not use the strongest mortar available?
Because stronger is not better in repair work. Brick industry guidance says repointing mortar should not exceed the strength of the original, since harder mortar can push stress into the brick and spall its face.
Do I need to be home during the masonry work?
Not always. Most masonry work happens outside, so we mainly need safe access to the chimney and a place to set up. We agree on access and timing when we schedule.
