Before you repair chimney masonry in South Lake Conway Villa

Plain talk about brick and mortar in South Lake Conway Villa, from the people who lay it.

Why repointing skill matters

Technical Note 46 makes a point worth repeating. An excellent mason may not be a qualified repointing craftsperson, and the potential for power tools to damage the surrounding brick should be weighed before work starts.

Repointing is slow, careful work at the edges of old brick. On chimneys it is done on a roof, around flashing and close to the flue. We plan the tools for each part of the job and slow down where the brick is soft or the joints are thin.

Why chimneys wear faster than walls

Sills, parapets, chimneys and copings, Technical Note 46 notes, experience more severe exposure than ordinary walls and may need repairs at shorter intervals.

A chimney above the roof has weather on all four sides and on top, and no roof overhang to shelter it. That is why a chimney can need joint work while the brick walls of the same house still look sound, and why we check it more closely than the walls around it.

White deposits and what they mean

White deposits on brick are left when moisture carrying dissolved material evaporates at the surface. Technical Note 46 says the water getting into the masonry should be investigated and fixed before the deposits are cleaned, or they will return.

Light deposits are generally water soluble and can often be removed by weathering, dry brushing or scrubbing with a stiff fiber brush and water. We treat them as a clue to where water is moving, not only as a stain.

Corbeled masonry at steps and shoulders

Where a chimney steps out from a wall or changes width, the masonry is corbeled, each course projecting a little past the one below. Section R1003.5 of the residential code limits how far a masonry chimney may be corbeled from a wall or foundation.

Cracks often show at those steps because the masonry changes shape there. We inspect them closely, and where a corbeled section is rebuilt, it is laid back within the code's limits rather than extended. Where cracks at a corbel come from movement rather than wear, we treat them as a structural question first.

Masonry questions we hear in South Lake Conway Villa

Question not listed? Our South Lake Conway Villa masonry team is glad to answer it by phone.

Do cracked mortar joints mean my chimney is unsafe?

Not usually on their own. Hairline cracks and worn joints are maintenance items, while wide cracks, cracks through several bricks, stepped or diagonal patterns and a leaning chimney point to movement that needs a closer look. We tell you which you have.

Can a chimney that has moved out of line be repaired?

Sometimes, but a chimney that has moved out of line needs a structural evaluation first. Brick industry guidance treats out-of-plane movement as a structural issue that may call for a professional engineer. We tell you plainly when that applies.
