Spalling Brick Repair Restores More Than Just the Surface
Brick spalling - the physical failure of a brick's face layer - is a fixable problem when caught early.
You've probably seen the signs already. Small brick fragments near the chimney base. A pitted or flaking surface on the upper courses. Maybe a chunk or two missing entirely from the front face.
Here's what that means: water got into the brick, froze, and pushed the face off. That's the freeze-thaw expansion cycle - water expands roughly 9% when it turns to ice, and porous masonry can't absorb that pressure without cracking.
The repair isn't just cosmetic. It covers where the damage is visible and where the moisture entered. That's the only way a spalling brick repair in Colorado Springs actually holds.

Colorado Springs Freeze-Thaw Cycles Are Harder on Brick Than Most Homeowners Expect
Colorado Springs brick faces some of the most demanding moisture conditions in the region.
This city doesn't get one long cold season with stable temps. It gets repeated freeze-thaw cycling - sometimes several times in a single week during late winter and early spring. A brick chimney might absorb moisture from a wet Tuesday snowmelt, freeze overnight Wednesday, and thaw again by Friday afternoon.
That cycling pressure compounds over years. Brick that looks structurally sound in October can show active spalling by April.
The Pikes Peak region adds another layer. Properties in Manitou Springs, Old Colorado City, and higher-elevation neighborhoods in Rockrimmon sit at elevations where temperature swings between day and night are more dramatic. Chimneys on those homes see accelerated surface deterioration compared to lower-elevation sites.
We serve the full region - from Fountain and Security-Widefield in the south to Monument and Black Forest in the north.
What I Saw on a Briargate Chimney That Shaped How We Approach Every Spalling Job
Finding the moisture source first is what makes a brick replacement last.From our lead masonry technician
I got a call from a homeowner in Briargate whose chimney had already been patched once. New brick on three courses. Fresh mortar. Looked clean from the street.
The homeowner was frustrated - and honestly, that was fair.
- 1The replacement brickBy the following spring, the new brick units were showing early-stage pitting. Same pattern as what had been removed.
- 2The crownWhen I inspected it, the crown was cracked in two places.
- 3The mortar jointsThe mortar joints above the roofline had never been repointed.
- 4The water pathThe water path was still wide open. Every rain event was pushing moisture straight into the replacement brick. Same entry point. Same failure.
That job reinforced something I've held onto since. Brick replacement without source identification means the same repair comes back around. So now, before we pull a single spalled unit, we document the crown condition, the mortar joint integrity, and the surface absorption rate of the surrounding masonry. Brick absorption rate - how quickly and deeply a unit takes on moisture - varies by manufacturer and age. Older Colorado Springs chimneys often have higher-absorption brick that needs surface sealing after repair, not just replacement.
We don't schedule the toothing work - the process of removing individual damaged units and installing matched replacements - until we know what let the water in. That sequence protects the new brick.
Matching the Brick Matters as Much as Installing It Correctly
Replacement brick that doesn't match the original creates visible patchwork - we source before we repair.
Here's what most homeowners don't realize about matching brick selection: it's not just color. Brick units vary in texture, dimension, and absorption rate. A slightly more porous replacement brick installed next to original units can become the new weak point in the very next freeze cycle.
Our process includes sourcing replacement units that match the color, texture, and porosity profile of the existing chimney brick. For older Colorado Springs homes - from historic homes in the Old North End to 1950s through 1980s homes in neighborhoods like Stratmoor - we sometimes source from salvage suppliers to match discontinued profiles.
The goal is a repair that looks uniform and performs uniformly under the same weather conditions.
Matched replacement
- Color, texture, and dimension matched
- Porosity profile matched
- Performs uniformly under the same weather
Mismatched replacement
- Visible patchwork
- More porous than the original units
- The new weak point in the next freeze cycle
Our Standards for Spalling Chimney Brick Repair
Every spalling brick repair we complete follows a clear, documented sequence.
- Source identification first: We locate and document the moisture entry point - open mortar joints, failed crown, missing cap, or failed surface sealing - before any brick is removed.
- Full toothing replacement: Damaged units are removed without disturbing adjacent courses. Replacement brick is matched for color, texture, and absorption.
- Repointing surrounding joints: New mortar joints are installed around all replaced units using compatible mortar mix - matched to the existing joint profile.
- Masonry surface sealing: We apply a vapor-permeable water repellent after repair. This reduces future moisture uptake while allowing the masonry to breathe - which prevents trapped moisture from causing new damage.
- Structural wythe check: If spalling has progressed through the outer wythe - the outer continuous vertical layer of masonry - we assess whether the inner wythe has been exposed to direct water intrusion.
- CSIA-certified documentation: Our technicians are CSIA certified. Findings and repair scope are documented for your records.
From first look to final seal, every step follows a confirmed sequence.
Our Spalling Brick Repair Process
Assessing the Crown, Joints, and Moisture Path
We start with a full visual assessment of the chimney exterior - crown, cap, mortar joint condition, and active spalling zones. We note the brick absorption rate on the damaged courses and check whether moisture has reached the structural wythe. If a liner issue or interior water intrusion is contributing to exterior brick failure, we flag that before repair scope is finalized.
Removing, Matching, and Setting Replacement Units
Spalled units are toothed out carefully - meaning removed individually without displacing the surrounding courses. Replacement brick is set in compatible mortar and sized to match the original joint profile. After units are installed and cured, all surrounding joints in the affected zone are repointed. Three passes. Not a single quick fill.
Sealing and Final Inspection
After mortar cure, we apply masonry surface sealing to all repaired areas. We do a final inspection of the crown and cap to confirm no remaining open moisture paths exist. The homeowner receives a written summary of what was found, what was repaired, and what conditions to watch in future seasons.

Frequently Asked Questions
Call and talk to the team directly.
Call (720) 505-5030Pricing for spalling brick repair requires an on-site assessment before any cost estimate is given. Repair cost varies based on the number of spalled units, whether the structural wythe is compromised, and what upstream moisture entry point needs correction alongside the brick work. Call 720-505-5030 to schedule an assessment with a written scope before any work begins.
Replacing spalled brick without fixing the moisture entry point causes the new brick to fail on the same timeline. Open mortar joints, a cracked crown, or a missing cap keep the water path active. Our CSIA-certified technicians document the source - crown condition, joint integrity, absorption rate - before any brick is toothed out. That sequence is what protects the replacement units through the next freeze cycle.
Most repairs complete in one to two visits, depending on the number of units replaced and mortar cure time. Source identification and brick removal happen first. Replacement units are set and repointed, then the masonry surface sealing is applied after the mortar cures fully. Rushing the cure window causes new joint failures - we don't skip it.
Yes - matching brick selection includes color, texture, dimension, and porosity profile, not just appearance. For historic homes in the Old North End and 1950s through 1980s homes in neighborhoods like Stratmoor, we source from salvage suppliers when current stock doesn't match discontinued profiles. A mismatched replacement brick with higher absorption than the surrounding units becomes the next failure point in a freeze cycle.
Spalling is a structural warning, not cosmetic damage. When the outer wythe - the continuous outer vertical layer of masonry - loses face material, the inner wythe becomes exposed to direct water entry. That path can reach the flue liner and firebox. CSIA-certified technicians check whether spalling has progressed past the surface layer before confirming repair scope.
Masonry surface sealing is included in the standard repair sequence, not sold separately. After mortar cures, we apply a vapor-permeable water repellent to all repaired areas. This material reduces future moisture absorption while still allowing the masonry to breathe - which prevents trapped moisture from creating new damage in the next freeze-thaw cycle.
