Spalled brick replacement, explained plainly

Matching brick size and shape

Bricks have been made in many sizes, and a replacement that is slightly too long or too thick shows at once. Brick industry guidance lists size alongside color and texture as properties the replacement should match.

We measure the existing units and look for a brick that fits the opening with normal joints. If the exact size is hard to find, we explain the options before anything is cut out. A unit that fits properly keeps the joint lines straight and the bond pattern intact.

Repellents wear off and need renewing

A water repellent is not a permanent layer. Brick industry guidance notes that repellents need reapplying over time, and that their performance should be judged on similar brick in similar exposure.

That is part of why we treat a repellent as a later, separate decision rather than a finishing touch on brick replacement. If one is chosen, you should know it becomes a maintenance item. Replacing damaged brick and fixing the water path remain the lasting part of the repair.

Loose top courses under a failing crown

Loose bricks at the very top of a chimney are often a sign that the crown and the courses under it have taken water for a long time. The mortar there may have washed out, and several units may lift together.

Replacing a few bricks may not be enough in that case. We explain whether the top courses need relaying before a new crown can sit on them. That work is priced separately, and the brick replacement lower down is planned around it.

Softer brick and the mortar around it

Some brick is softer and more absorbent than others. Federal preservation guidance explains that in a wall of soft brick, a soft, permeable mortar is needed so moisture can leave through the joints rather than through the units.

If your chimney is built of softer brick, the mortar around replacement units is chosen with that in mind. A hard mix would push the problem into the bricks next to the repair. We explain the mortar choice so you can see how it protects the existing brick.

Questions to ask before replacing bricks

Is spalled brick near the ground treated differently?

Brick near the ground can stay wet from the soil or from water splashing back. Brick industry guidance lists rising damp among possible causes of masonry distress. We look at drainage and plantings at the base as well as the brick itself.

Can one cracked brick wait, or should it be replaced now?

A single hairline crack in an otherwise firm brick may be watched. A crack through the face, a loose unit or a face that is coming away should be replaced, because water can keep entering there. We explain which applies.

Will you check the crown while replacing bricks near the top?

Yes. Bricks near the top often suffer because water comes from above. We check the crown, cap and flue seal, and if one of them is failing, we explain it and price it separately.
