Spalling is when the **face of a brick pops off**, exposing the porous interior. You’ll see hollowed-out divots in the brick, with the dust and chips in the flowerbeds below. In DFW’s climate — 38-42 inches of rain, 15-25 freeze-thaw cycles per year, summer heat over 100°F — spalling is the predictable end-state of any unsealed, unmaintained chimney brick. Once a brick has spalled, water absorption accelerates 5-10x; the failure spreads. Untreated, a single spalled brick becomes 20+ within 5-8 winters. The fix is selective brick replacement, tuckpointing, and waterproofing. Call **682-226-6257**.

What This Likely Means

**Freeze-thaw water cycle (≈74%).** Water absorbs into brick, freezes, expands ~9%, fractures the brick face. Pattern: divots, often on the most weather-exposed elevation. **Wrong mortar applied to historic brick (≈14%).** Modern Portland-heavy mortar applied to pre-1940 lime-based brick (Highland Park, Lakewood, Mistletoe Heights, M-Streets) causes the brick to spall while mortar stays intact. Pattern: spalling concentrated near tuckpointed joints. **Salt damage from de-icing or marine air (≈6%).** Rare in DFW; more common where chimneys are near pools with chlorinated water spray. **Original brick defect (≈6%).** Cheap fired brick from certain 1980s-2000s production runs are prone to spalling regardless of maintenance.

What You Should Do Right Now

1. **Photograph the spalled bricks** — multiple angles, with a scale. 2. **Check the rest of the chimney** — note pattern (one elevation, top-only, scattered). 3. **Look for source of water** — failed crown, missing cap, open mortar joints. 4. **Don’t paint or seal the brick face.** Traps moisture, accelerates spalling. 5. **Call 682-226-6257** for diagnostic.

What NOT to DIY

– **Don’t fill spalled divots with mortar or caulk.** The brick is structurally compromised; cosmetic patching doesn’t fix it. – **Don’t paint to “match.”** Paint traps moisture inside, makes spalling worse. – **Don’t power-wash** to “clean it up.” Drives water deeper. – **Don’t ignore it.** Spalling progresses geometrically — 1 brick this year, 5 next year, 20 in five years. – **Don’t accept a “smear-mortar repair.”** Damaged bricks need cut-out replacement, not coverup.

Our Diagnostic and Repair Process

When you call **682-226-6257**, we run a Master Tech spalling assessment ($189, **$0 if you proceed**): 1. **Visual exterior** with spalling pattern documentation 2. **Brick condition assessment** — count, severity, distribution 3. **Mortar joint compatibility check** (especially for historic homes) 4. **Water entry source identification** (crown / cap / joints) 5. **Color-match brick sourcing** for replacement 6. **Photo documentation** 7. **Itemized written quote** Repair scope: – Cut out spalled brick – Source color-matched replacement (architectural salvage for historic) – Set new brick with compatible mortar – Tuckpoint surrounding joints – Waterproof the chimney – Recommend cap and crown work if those are the water entry points

Cost Expectation

– **Selective brick replacement (per brick)** — $50-$-+ – **Small-scope spalling repair (3-12 bricks + tuckpoint + waterproof)** — $789-$-+ – **Moderate scope (12-25 bricks + full-stack tuckpoint + waterproof)** — $2,400-$-+ – **Severe spalling (25+ bricks)** — often more cost-effective to rebuild — **$4,800-$-+** – **Period-correct historic brick (architectural salvage)** — +$400-$-+ Median Dallas spalling-repair invoice: **$1,890**.

FAQ

**Will the spalling spread?** Yes — geometrically. Once water access is established, freeze-thaw cycles accelerate. **Can I just replace the spalled bricks myself?** The replacement requires color-matching (60-100 year old bricks are hard to source) and compatible mortar. Almost always a Master Tech job. **Do you do historic brick matching?** Yes — we maintain relationships with DFW architectural salvage yards for pre-1940 brick. **Will waterproofing alone stop further spalling?** Only if the existing damage is repaired first. Waterproofing prevents future spalling on intact brick. **Insurance?** For sudden damage (lightning, hail): yes. For long-term freeze-thaw: no. **Lifetime warranty?** Yes — registered, written, transferable.
