Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Altadena, CA
Chimney repair in Altadena usually means working on a house built before 1940, often with an original clay-tile flue that was never intended for the way we burn wood today. We’re Mantel Chimney Sweep, and we’ve served Altadena since 2018, focused on repair work that lasts rather than cleanings that simply get you through one season. If your fireplace has a cracked liner, spalling brick, or a flashing that leaks during foothill rain, call (844) 821-5749 and we’ll diagnose it with camera equipment you can see for yourself.
Why Altadena Homes Are Different
Altadena sits pressed against the Angeles National Forest foothills, and that geography shapes nearly every chimney we open. The town has an unusual concentration of pre-1940s Arts and Crafts and Craftsman bungalows, many with original brick fireplaces and clay-tile flues that predate modern building codes. These are not decorative post-war fireplaces. They’re working masonry systems, and in many Altadena households they’re still a primary heat source through the colder, wetter winters that settle in at the base of the San Gabriels.
We routinely see original 1920s clay tiles on the north-side streets that climb toward the foothills, and those tiles develop gaps that must be addressed before the first heavy rain. Cooler temperatures and more rain than nearby Pasadena mean longer burn seasons and more creosote from slow, smoldering fires. Add in the significant diurnal temperature swings this area gets, and you have a recipe for masonry cracking and spalling that most homeowners never notice until water shows up inside the house.
Styles & brands we work with
Our Main Altadena Services
Most Altadena homeowners call us for one of two reasons: a fireplace that needs a proper sweep, or a dryer vent that has become a fire hazard. Both are covered here.
Chimney Sweep in Altadena
In Altadena, a chimney sweep often means removing heavy creosote from a flue that sees consistent wood burning from fall through early spring. Older Craftsman fireplaces tend to draw differently than modern units, and the creosote they produce is more stubborn. We sweep with rotary tools sized to your flue, inspect the liner as we go, and tell you plainly whether the chimney can wait another year or needs repair before you light another fire. For the full scope of our sweeping work here, see Chimney Sweep in Altadena.
Dryer Vent Cleaning in Altadena
A clogged dryer vent is one of the top causes of residential fires, and older Altadena homes often have long, multi-turn vent runs that trap lint quickly. We clean the full run from dryer to exterior termination, remove the packed lint, and verify airflow before we leave. If your dryer has been taking longer than it should or the exterior flap barely moves, this is the service to book. Details on our dryer vent process are on our Dryer Vent Cleaning in Altadena page.

Chimney Repair in Altadena
Chimney repair in Altadena tends to come down to one of a few recurring problems: a clay-tile liner cracked by decades of heat cycling, a flashing that leaks where the chimney meets a composition or tile roof, or a crown that has crumbled under foothill weather. Homes here were built between the 1900s and 1950s, and many still have unlined chimneys or single-wythe brick with deteriorated mortar joints. The climate accelerates it: prolonged wood-burning seasons, rain that comes in hard against the San Gabriels, and temperature swings that freeze-thaw masonry until it spalls.
We repair what a sweep-only operator can only report. When a camera inspection shows a cracked flue, we can restore it with HeatShield cerfractory sealant or reline it entirely with a DuraFlex stainless steel system. That’s the difference: one company that both diagnoses the problem and fixes it. Our full repair scope lives on our Chimney Repair hub page.
Chimney Cap Installation
Signs you need it
You have no cap at all, or the existing cap is rusted through, letting rain, leaves, and birds into your flue.
What it costs in Altadena
Expect $200 – $700 for a standard cap installation, with stainless steel caps at the higher end.
How we do it
We measure the flue, install a stainless or copper cap sized for your tile or liner, and secure it with mechanical fasteners rated for foothill wind.
Chimney Liner Installation
Signs you need it
Your camera inspection shows cracked tiles, gaps between tile sections, or no liner at all in a home built before code required one.
What it costs in Altadena
A full liner installation typically runs $2,500 – $7,000 depending on flue size, roof access, and whether we’re relining for a gas appliance or a wood-burning fireplace.
How we do it
We size a DuraFlex flexible stainless liner to your flue, insulate where code requires, drop it from the top, and connect it to an approved termination cap.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near your fireplace, damp brick after rain, or visible gaps where the chimney meets the roofline.
What it costs in Altadena
Flashing repair in Altadena generally falls between $300 – $1,200 depending on whether we’re patching a section or replacing the full flashing system.
How we do it
We remove the old flashing, install new step and counter flashing using materials from Olympia Chimney or Famco, and seal every seam with a high-grade polyurethane sealant.
What Chimney Repair Costs in Altadena
| Item | Typical range in Altadena |
|---|---|
| Chimney cap installation | $200 – $700 |
| Chimney liner installation | $2,500 – $7,000 |
| Chimney flashing repair | $300 – $1,200 |
How long does chimney repair take in Altadena?
Most repairs finish in a single day. A liner installation may take two days if we’re dealing with difficult roof access on a steep foothill lot. We’ll give you a clear timeline before work starts, and we never recommend work without camera evidence you’ve seen yourself.
Do Altadena homes always need a liner replacement?
No. Many original clay-tile flues are still sound. If the camera shows minor cracking, HeatShield sealant can often restore the flue for significantly less than a full liner. We only recommend replacement when the structural integrity of the tile is actually compromised. Call (844) 821-5749 and we’ll show you the footage.
Brands We Service in Altadena
We work with professional chimney-industry materials from Olympia Chimney, Famco, and Copperfield, and we stock common cap sizes and flashing components for faster turnaround on Altadena jobs. That means less waiting when your repair can’t be delayed. See our brands for the full list.

What Altadena Customers Say
"They were the only ones willing to just tell me the price. Everyone else wanted to "come take a look" first, which in my experience means come apply pressure in person."
— Matt Delaney"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
— Diego Delgado"Good work. The written inspection report took about a week to arrive after I asked for it, which was slower than I expected."
