Brick and Spalling Repair Cost Calculator
Spalled bricks are priced one at a time. Count the flaking bricks, enter your per-brick rate, and fix the water source or they come right back.

Spalling is brick face flaking off after freeze-thaw with trapped water. Replacing 25 bricks at $12.00 each plus access is about $495 — and fix the water source (often a bad crown or cap), or it comes right back.
Spalling is the flaking, popping and crumbling of a brick’s face. It happens when water soaks into the masonry, freezes, and pushes the outer skin of the brick off — the classic freeze-thaw failure. Because each damaged brick has to be individually cut out and a matching one reset, the work is priced per brick, so the estimate is a simple count times a rate plus the cost of getting up there.
But the brick count is only half the job. Spalling is a symptom of trapped water — a failed crown, a missing cap, bad flashing or a joint that lets water in behind the face. Replace the bricks without fixing the water and you will be counting new spalled bricks in a couple of winters. Every spalling repair should come with a plan to keep water out.
Formula
Count times rate, plus access, with a cushion:
total = (n_bricks × rate_per_brick + access) × (1 + contingency)
The per-brick rate rolls the material and the cut-and-reset labor into one number — read it from the quote so the total tracks real local pricing.
Worked example
A freeze-thaw winter left 32 bricks spalled on the weather side of a chimney. The mason quotes $13.50 per brick to cut each out and reset a color-matched replacement, plus $175 for ladder-and-plank access. 10% contingency:
(32 × 13.50 + 175) × 1.10 = (432 + 175) × 1.10 = 607 × 1.10 ≈ $668
Add a crown seal or cap in the same visit — otherwise this $668 becomes an annual bill.
Count the bricks, then stop the water
- Count only truly spalled bricks. Surface efflorescence (white salt haze) is not spalling and does not need replacement — it washes or brushes off.
- Find the water source first. Look up-slope of the damage: a cracked crown, a missing cap or failed flashing is usually feeding it. Budget that fix alongside the brick.
- Match brick and mortar. Replacement bricks should match size, color and hardness; mismatched hard mortar can spall the neighbors next. A mason who sources matching brick is worth it.
- Consider a breathable repellent — carefully. A vapor-permeable masonry water repellent can help, but sealing wet or damaged brick traps moisture and makes spalling worse. Fix and dry first.
Reference table
Related masonry planning bands — spalling often travels with failed joints and a bad crown, and heavy spalling can tip a chimney toward a rebuild:
| Masonry job | Typical planning band |
|---|---|
| Tuckpointing (per linear foot) | $8–$25 / linear ft |
| Crown repair / replacement | $200–$3,500 |
| Chimney rebuild | $1,000–$6,000 |
These are labeled planning bands — a reality check on a written quote, never a price you should expect to pay. Chimney cost swings with roof access and scaffolding, chimney height, roof pitch, how far the damage runs and local labor.
