Spalled brick replacement, explained plainly
What spalling brick repair involves on a chimney
Spalling brick repair replaces units whose face has flaked, popped off or cracked through. The damaged brick is cut out, the opening is cleaned and a matching brick is set in fresh mortar. Sound brick around it stays in place.
The other half of the job is the cause. Water is usually part of the cause. We look for where that water comes from and explain it alongside the replacement. New units should not be asked to survive the conditions that broke the old ones.
Surface marks versus a lost brick face
Not every mark on a brick means it needs replacing. Stains, shallow scuffs and weathered texture can leave a unit sound. What matters is whether material has been lost from the face or whether the brick has cracked through.
We look at each suspect unit and separate cosmetic marks from real damage. Only units that have lost their face, cracked through or come loose go on the replacement list. You see that list before approving, so the scope reflects the damage rather than the look of an old wall.
Coatings that trap moisture behind the face
Some coatings form a film on the brick. Brick industry guidance on clear coatings explains that film formers slow the drying of the masonry through its face. Water held inside can lead to clouding and to spalling.
If your chimney was sealed or painted and the faces are now coming away, the coating may be involved. We explain what we see and whether the remaining coating affects the replacement work. New units are not coated as part of the job, and any later treatment is discussed separately.
A free inspection before any brick comes out
Brick replacement starts with a free inspection. We check each face of the chimney, mark damaged units and test suspect bricks. The crown, cap, flashing and joints that could be sending water into the wall are checked too.
The findings are explained on site, and a free written estimate follows that sets out every item separately. There is no charge and no obligation. If the bricks can wait, we say so and explain what would make replacement necessary. Keep the written findings for any later visit.

Questions to ask before replacing bricks
How many bricks can be replaced before a bigger repair is needed?
There is no fixed count. It depends on how the damage is spread and whether the masonry around it is sound and not moving. When damaged units cluster in large areas or courses are loose, we explain a partial rebuild instead.
Can you replace bricks on the part of the chimney above the roof?
Yes. Access is planned from the roof, with protection for the roof covering. Bricks near the top often take the most water, so we also check the crown and cap above them before replacing units.
Why are bricks from an earlier replacement flaking again?
When replacement units fail in the same spot, the cause may not have been fixed. Water may still reach that area, the mortar may be too hard or the brick may not suit the exposure. We look for the cause before replacing them again.
