AfterMortar Repointing in Pasadena, CA
Mortar repointing is the process of removing deteriorated mortar from between chimney bricks and replacing it with fresh, correctly mixed mortar. In Pasadena, where homes range from 1920s Spanish Colonials in Bungalow Heaven to mid-century ranch styles in Hastings Ranch, we see failing mortar on chimneys of every era. The fix matters because the mortar joints are what keep water out of the brick structure. Once they start crumbling, moisture gets in, freeze-thaw cycles do more damage, and the chimney begins a slow structural decline.

When You Need Mortar Repointing
Not every crack means the chimney is failing. But certain conditions in Pasadena make mortar deteriorate faster here than in drier parts of Southern California. Our proximity to the San Gabriel Mountains means we get more rain than most of LA County, and homes in the foothills, around Linda Vista and Annandale, see real seasonal moisture. That water works into hairline cracks, and every winter the occasional cold snap does the rest.
Here’s what tells us repointing is due:
- You can scratch mortar out with a fingernail or a key. Sound mortar is hard. If it turns to sand under light pressure, the binder has failed and water is getting in. We see this most often on chimneys 60 years and older in neighborhoods like Madison Heights and Orange Heights.
- There are gaps or missing chunks between bricks. Not hairline cracks, but actual voids where mortar used to be. Those are open channels for rain. During Pasadena’s winter storms, a single open joint can funnel surprising amounts of water into the chimney chase and down into the home’s framing.
- White staining on the brick face. That chalky white deposit is efflorescence. It means moisture is migrating through the masonry and depositing salts from inside the mortar. It’s a symptom, not a stain you can just wash off. Behind that staining, the mortar is degrading from the inside out.
- Water in the firebox after a rain. If you find dampness, puddles, or a musty smell in the firebox after Pasadena’s winter rains, the most common entry point is failed mortar joints higher up the chimney. Flashing failure and missing caps are also culprits, but we almost always find joint deterioration as an aggravating factor.
- Brick face spalling. Spalling is when the brick surface flakes off in sheets. This happens because water trapped behind the brick expands and contracts. The mortar was supposed to be the sacrificial layer. When it’s too hard or too far gone, the brick takes the damage instead.
If any of these match what you’re seeing, the next step is a proper look. We don’t diagnose over the phone, but we’ll tell you honestly on the call whether an inspection makes sense. Call (626) 657-5513 and someone live will answer, no voicemail tree, 24 hours a day.
Our Mortar Repointing Process
We follow a set procedure on every repointing job. It’s the same one we use across the Garrison Partners family, and it’s built to make sure the new mortar bonds correctly and lasts. Here’s the order of work:
- Written assessment and price. We inspect the chimney, note every joint that needs work, and write down the scope. You get a price in writing before you approve anything. That number is the number on the invoice. No surprises at the door.
- Joint preparation. We grind out the failed mortar to a consistent depth, typically 3/4 inch, using the right tools to avoid damaging the brick edges. Undersized grinding means the new mortar won’t have enough depth to hold; oversized grinding weakens the brick itself. The depth is set by the joint width and brick condition.
- Dust control and cleanup. Repointing produces fine dust. We cover the work area, use dust-containment methods appropriate to the site, and clean the roof and ground surfaces before we leave. You won’t find a mess after we’re gone.
- Mortar mixing and application. We mix mortar to match the existing joint in color, texture, and compressive strength. This matters more than homeowners expect. A mortar that’s too hard traps moisture behind the brick and causes spalling. Too soft and it washes out in five years. We match the original where possible, especially on older Pasadena homes where the original mortar was lime-based.
- Tooling and curing. New joints are finished to match the surrounding profile, whether that’s a flat raked joint or a rounded concave one. We then protect the work while it cures so the mortar doesn’t dry too fast in Pasadena’s summer heat. Fast drying is a common cause of weak, crumbly joints.
- Final walkthrough and guarantee. We walk you through what was done, point out what we found, and confirm the written guarantee is on file. One full year. If a covered repair fails within that period, we come back at no charge.
Every technician who shows up at your door in Pasadena is background-checked and in uniform. You’ll know exactly who you’re letting onto the property.
Mortar Repointing Pricing in Pasadena
For a typical single-story chimney in Pasadena, repointing runs $1,200 to $2,600. Two-story homes run higher, usually $2,200 to $3,800, because of ladder and roof work, longer setup, and more careful staging. The range depends on four things:
- How many joints need work. Sometimes it’s a single face of the chimney. Sometimes all four sides are crumbling. We price per scope, not per brick, but the more linear feet of joint we’re grinding and refilling, the higher the cost.
- Chimney height and roof access. A single-story bungalow off the 210 in northeast Pasadena is a straightforward setup. A taller chimney on a steep pitch in the San Rafael Hills means safety lines, specialized ladders, and more time. That’s reflected honestly in the price.
- Brick condition. If the brick is spalling, some bricks may need replacement before we repoint. We don’t hide that in the fine print. When we see it during the assessment, we put it in the written scope and price.
- Material match requirements. Most Pasadena homes can use a standard Type N or lime-blend mortar. But if the home is historic, in a historic district, or the chimney faces the street and you want an exact color match, we may need a custom-tinted blend. We’ll spec products from brands like Olympia Chimney or Copperfield when the job calls for it, not because a supplier offered us a better margin.
What Repointing Typically Costs by Chimney Type
- Single-story, one face damaged: $1,200 to $1,800
- Single-story, full repoint: $1,800 to $2,600
- Two-story, one face damaged: $2,200 to $3,100
- Two-story, full repoint: $2,600 to $3,800
This is not a placeholder range. These numbers reflect what we see on Pasadena jobs in 2025. The free estimate we give you will pin the exact number down in writing before any work starts. If you’re comparing quotes, ask the other company whether their price includes joint preparation depth, cleanup, and a written guarantee on the masonry. Ours does, every time.
FAQs – Mortar Repointing
How much does mortar repointing cost in Pasadena?
Mortar repointing in Pasadena costs between $1,200 and $3,800 depending on chimney height, the number of damaged joints, and whether brick replacement is needed. Single-story full repoints typically run $1,800 to $2,600; two-story full repoints run $2,600 to $3,800. Every Flint Chimney Co Pasadena estimate is free and in writing, so you’ll have an exact price before you approve anything. Call (626) 657-5513 for your number.
Can you do repointing the same day?
We can often begin same-day repointing if we’re already on site for an inspection and the scope proves small, but most repointing work is scheduled within a few days so we can properly prepare joints, match mortar, and allow correct curing. What we don’t do is rush mortar so it fails in two years. Call us at (626) 657-5513 and we’ll give you a straight answer on scheduling.
Is it cheaper to repoint than to rebuild the chimney?
Yes, repointing is substantially cheaper than a partial rebuild, usually a third to a half of the cost of rebuilding the same section. But repointing only works when the brick itself is sound. If the bricks are spalling, shattered, or structurally loose, repointing alone won’t hold and you’ll spend the money twice. That’s why our written assessment calls out brick condition before we quote anything.
What type of mortar do you use for repointing in Pasadena?
We match mortar to the existing chimney’s age and brick hardness. For most Pasadena homes built before 1960, we use a lime-forward mortar with appropriate compressive strength so the joints can flex and breathe. For newer masonry, a Type N mortar is usually the correct choice. We source our materials from professional chimney supply lines, including Olympia Chimney and Copperfield products where they fit the job.
