Spalled brick replacement, explained plainly

Mortar that behaves like the existing mortar

Brick industry maintenance guidance asks that the new mortar have physical properties similar to the existing mortar. That way the repaired area moves, absorbs and dries like the wall around it.

We look at the existing joints before choosing the mix. Brick industry guidance on mortar selection, which follows the ASTM classification for masonry mortar, favors the lowest strength that meets the need. We explain the choice so you understand why the mortar suits your chimney rather than simply being the strongest available.

Brick corners damaged by earlier grinding

Chipped brick edges along the joints can trace back to an earlier repointing done with a grinder. Federal preservation guidance shows how power tools used on thin joints break brick edges and overcut the joints.

Damaged edges make joints look wider and leave thin mortar at the face. Where the damage is cosmetic, the bricks may stay. Where edges have broken away enough to let water in, replacing the unit may be the better answer. We explain which applies to each area.

When the count of damaged bricks grows large

Single-brick replacement suits damage scattered through otherwise sound masonry. When damaged units cluster across large areas, or whole courses are loose, cutting out bricks one by one stops making sense.

We explain where that line falls on your chimney. A partial rebuild of the affected section may be the sounder repair, and it is priced as its own job. You see both options with their reasons, so the choice between them is yours and made with the full picture. Sound sections of the chimney stay out of either scope.

A record of which bricks were replaced

After the work, you receive a written record listing the units replaced and where they sit on the chimney. It also notes the brick and mortar used and anything we saw that falls outside the job.

That record is useful later. If more bricks need replacing, the same brick and mortar can be sourced again. If you sell the house, it shows what was done. Keep it with your other papers about the home. It also helps a future contractor understand what is already in the wall.

Chimney brick questions we hear

How do you match new brick to an older chimney?

We compare size, color, texture and the range of shades in the wall, and we can set out a sample to judge the match. Finding a close brick can take some searching. New brick may look fresher at first.

Should I pull off loose pieces of brick myself?

No. Pulling on loose pieces can bring down more than you expect, and working on a roof carries real risk. Keep people clear of the area below and tell us what you have seen.

Do you replace the firebrick inside the fireplace too?

Firebrick lining the firebox is a different material and job, handled under firebox repair. Chimney brick replacement covers the exterior masonry. If both need attention, each is priced separately so you can decide.
