Crumbling mortar, brick faces flaking off, a cracked crown, a stack that has started to lean. We repoint the joints, swap the spalled brick, rebuild the crown and, where it is needed, rebuild the stack itself, matched so the repair looks like it was always there.
Open mortar joints, a hairline crack in the crown, one spalling brick. Each one lets water into the masonry, and water is what turns a minor repair into a rebuild. Caught early, the same problems are a morning of work rather than a new chimney.
Masonry chimney repair is the work that restores the brick and mortar of a chimney, from repointing worn joints and replacing spalled brick to rebuilding the crown or the stack above the roofline, so it sheds water and stands solid again without a full teardown.
A brick chimney is a stack of separate parts that all have to keep water out. The mortar joints lock the bricks together, the bricks themselves take the weather, the crown sheds rain off the top, and the flashing seals where the stack meets the roof. When one of those gives up, the rest starts to follow.
Mortar is usually first to go, because it is mixed softer than the brick on purpose so the stack can move without cracking. Once the joints open, water tracks in behind the brick. That water freezes a little on cold nights, soaks the face, and starts popping the front off the bricks, which is the flaking you see as spalling.
In Los Angeles the wear comes from a few directions at once. Sun bakes the south face year round. A long dry spell followed by a burst of winter storms swells and shrinks the masonry. Add the odd bit of ground movement and, over the decades, joints drop out, crowns crack, and brick faces let go.
The repair depends on how far it has run. A sound stack with worn joints needs repointing. Spalled or cracked brick gets cut out and replaced. A failed crown gets rebuilt. Once the stack is leaning or cracked through, that points to a partial or full rebuild. We look first and tell you which one it actually is.
Tell us what the brickwork looks like when you call. It usually tells us whether this is a spot repair, a crown, or the whole stack.
A sound joint sits nearly flush with the brick. Once the mortar crumbles to sand under a screwdriver, or you can fit a coin into the recess, the joint has stopped sealing and stopped carrying its share of the load.
This is repointing. We grind the failed joints out to a clean depth and pack in fresh mortar. Caught here it is a tidy repair, before the open joints let the bricks themselves start to move.
When the front of a brick blisters and sheds in layers, that is spalling. Water has soaked into the brick and broken the face off from the inside. The rough, pitted brick left behind soaks up even more water.
Spalled brick does not heal. We cut the failed units out and replace them with brick matched to what is there, then close up whatever let the water in so the new brick does not go the same way.
The crown is the sloped slab that caps the top of the chimney and throws rain clear of the brick. When it cracks or breaks up, water runs straight down inside the stack and into every joint below it.
A crown is often rebuildable on its own. We break out the failed slab and recast a proper crown with an overhang, which is one of the cheapest repairs that protects the whole chimney beneath it.
That white bloom on the brick, efflorescence, is salt left behind as water moves through the masonry and dries. Damp patches on the ceiling or wall near the chimney are the same water, tracking further in.
We find where the water is getting in, whether that is open joints, spalled brick, a cracked crown or bad flashing, and close that path. A breathable sealer afterward keeps the brick from drinking the next storm.
If the chimney is visibly tilting, bulging or has stair-step cracks running through the brick, the trouble has moved past the joints and the crown into the structure itself.
Patching will not straighten that. We take a proper look and, when it is needed, rebuild the stack from a sound course up, rather than sell you pointing that will not hold on a chimney that has already moved.
Masonry repair looks simple enough that it invites shortcuts. The most common one is fixing what you can see and ignoring why it happened. Fresh mortar gets smeared over a shallow joint, a spalled brick gets skimmed with filler, and the chimney looks fixed for a season.
The other common miss is the wrong mortar. Vintage brick is relatively soft and needs a softer mortar around it that can still flex and breathe. Pack a hard, high-cement mix into those joints and the brick becomes the part that gives instead. The faces start cracking and popping off, and now there is a brick problem on top of a joint problem.
We work the other way around. We find where the water is getting in and close that first, grind joints out to a real depth before repointing, and match new mortar and brick to the original in strength, color and finish. That is the difference between a repair that lasts and one that peels off by the next winter.
Repairing at the right time is one of the cheapest ways to extend a chimney. Left too long, a joint or a crown turns into a rebuild.
Most of the craft is in reading the chimney right and prepping it properly. The visible repair is the satisfying part at the end.
Joints, brick, crown and flashing, and where water is getting in. That decides whether this is repointing, brick replacement, a new crown, or a rebuild.
What we are repairing, what we are replacing, and the number. Nothing starts until you have said yes to it, and we tell you what can safely wait.
Failed joints ground out to a clean depth, spalled brick cut free, a broken crown broken off. Fresh work only bonds to sound material, so this is the step shortcuts skip.
Mortar mixed to suit your brick and tinted to match, replacement brick chosen to blend, crowns recast with a proper overhang, tooled to the same profile as the original so the repair disappears.
We clean the brick faces down and, where the masonry needs it, follow with a breathable waterproofer so the fresh work is protected from the next wet season.
It covers the brick-and-mortar repairs a chimney needs short of a full teardown. Repointing worn joints, replacing spalled or cracked brick, rebuilding a failed crown, and rebuilding the stack above the roofline are the common ones. When you call, we take a look and tell you which of those your chimney actually needs.
In everyday use people mean the same thing by both, which is grinding out worn mortar joints and packing in fresh. Strictly, repointing renews the mortar and tuckpointing is a finish that uses two colors for a crisp look. Either way it is one part of masonry repair, and we will tell you if a decorative finish is what you are after.
Yes, and it matters more than most people realize. We match mortar for strength so it suits the age of your brick, and we tint and tool it to match the color and joint profile. For replacement brick we source the closest match we can find. Done right, the repair blends in rather than standing out as a patch.
If the trouble is in the joints, the brick faces or the crown and the structure is still sound, repair is usually all it takes. Once the stack is leaning, bulging or cracked through the brick itself, that is structural and points toward a partial or full rebuild. We look first and give you the honest version, not a repair quote for a rebuild problem.
Almost always because it treated the surface and not the cause. Mortar smeared over a shallow joint, filler skimmed over a spalled brick, or a mix too hard for the brick. All of it peels or cracks within a season or two. Finding where the water gets in, prepping to solid material, and matching the materials are what make a repair last.
Repointing and brick replacement done with the right materials and proper prep can hold for decades, often as long as the original did. A recast crown lasts similarly. Sealing the masonry afterward and keeping the crown and cap in good shape stretches it further by keeping water out of the fresh work.
It comes down to how much of the chimney needs work. Spot repointing or a handful of replacement bricks sits at the low end, a recast crown is a defined job, and a partial rebuild costs more. We look, give you the number before we start, and tell you if any of it can safely wait.
Tell us what the brickwork looks like and we will tell you where it stands. Scope first, price before we start, and brick and mortar matched so the repair looks like it was always there.
