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 Monrovia, CA
Chimney repair in Monrovia usually starts with a cracked flue tile or a crown that’s been pushed apart by years of earthquake movement and Santa Ana wind debris. The foothill homes here, especially the 1920s-40s bungalows near Old Town and the canyon-adjacent streets climbing into the San Gabriels, have original masonry that doesn’t fail the way newer builds do. We’re Chimney Sweep Montebello, and we handle the full chimney repair scope in Monrovia: liner installation, cap replacement, flashing work, and crown repair. Call (833) 362-8107 for a free estimate.
Why Monrovia Homes Are Different
Monrovia sits at the base of the San Gabriel Mountains, and that changes everything about chimney work. Cold canyon air pushes downhill at night, so fireplaces in the foothill neighborhoods get used more often and for longer stretches than in the flatter valley cities nearby. Wildfire smoke and ash from nearby hills settle on chimney caps, crowns, and inside flues every fall. We find spark arrestor caps packed with oak leaves and ash on the homes near the canyon mouths, a maintenance pattern you won’t see in El Monte or Arcadia.
The housing stock itself is the other factor. Many Monrovia chimneys are original to 1920s-40s Craftsman and Spanish Colonial homes, built with clay tile liners and mortar that’s now pushing a century old. The combination of earthquake movement and repeated heating cycles means spalling mortar joints and cracked flue tiles are common findings. A sweep that only removes creosote won’t address what’s actually failing in these chimneys. We diagnose the masonry and the liner before we quote, because a Monrovia chimney from that era rarely needs just a cleaning.

Our Main Monrovia Services
Most Monrovia homeowners call us for one of two things: a thorough sweep before burning season, or a repair uncovered during that sweep. Here’s how each works.
Chimney Sweep in Monrovia
A Chimney Sweep in Monrovia on an older foothill home starts with the liner, not the firebox. Ash and ember debris from Santa Ana events settle in flues every year, and in the canyon-adjacent streets we often clear more wind-driven material than creosote. We run a camera through the flue before and after sweeping so you can see what came out and whether anything cracked during the last heating season. The older clay tile liners common here rarely survive decades of use without some damage, and the camera shows that plainly.

Dryer Vent Cleaning in Monrovia
Lint is the same ignition hazard creosote is, and in Monrovia homes with long vent runs from basement or hillside laundry rooms, it builds faster than most people expect. A Dryer Vent Cleaning in Monrovia is a fire-risk reduction service, not a convenience. We brush the full run from dryer to exterior termination and check for the sagging or crushed duct common in older bungalows with tight crawl spaces. If you’ve noticed longer dry times or the exterior flap isn’t opening fully, the vent likely needs attention.

Chimney Repair in Monrovia
Chimney repair in Monrovia is usually driven by what the age of the house and the foothill climate do to original masonry. Clay tile liners in 1920s-40s chimneys crack from decades of heating cycles and earthquake movement, and crowns that were mortared by hand don’t always shed water the way they should. Our repair work uses contractor-grade materials from Olympia Chimney, Famco, and Copperfield, and we handle everything from cap replacement to full liner installation. If you’ve been told you need a rebuild, get a camera inspection first. A DuraFlex liner or HeatShield resurfacing often restores a flue without demolition. That’s the core of what our Chimney Repair work covers.
Chimney Cap Installation
Signs you need it
Rain streaking down the flue, rust staining on the damper, or animal noise in the chimney are the usual signs a cap is missing or failing.
What it costs in Monrovia
Cap installation in Monrovia typically runs $160 to $340 including the cap and the labor to secure it to the flue.
How we do it
We measure the flue opening, install a properly sized cap, and secure it so Santa Ana gusts can’t lift it.
Chimney Cap Replacement
Signs you need it
A cap that’s rusted through, dented from falling branches, or missing its spark arrestor mesh should be replaced rather than patched.
What it costs in Monrovia
Replacement typically runs $160 to $340, depending on flue size and whether the old cap left damage that needs attention.
How we do it
We remove the old cap, inspect the flue rim for cracks or mortar loss, and install a new cap sized to the flue.
Chimney Liner Installation
Signs you need it
Cracked clay tiles, missing mortar joints, or flue gases leaking into the house are all signs the liner has failed and needs replacement.
What it costs in Monrovia
Liner installation in Monrovia typically runs $2,165 to $3,355, depending on flue height and whether we’re running a DuraFlex flexible liner through existing offsets or a straight vertical flue.
How we do it
We run a camera first, then pull the new liner through, insulate where needed, and connect it to the appliance before testing the draft.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near the chimney, damp drywall in the attic, or visible gaps between flashing and brick all point to failed flashing.
What it costs in Monrovia
Flashing repair typically runs $225 to $600 when the existing flashing can be resealed or small sections replaced.
How we do it
We pull the compromised section, check the mortar and counterflashing, and install new material before resealing the joint so water can’t track down into the roof deck.
Chimney Crown Repair
Signs you need it
A cracked, spalled, or eroded crown lets water into the masonry and accelerates the freeze-thaw damage that’s common on older Monrovia chimneys.
What it costs in Monrovia
Crown repair typically runs $600 to $1,700 depending on the damage, with full replacement usually $1,200 to $2,500 when the existing crown can’t be salvaged.
How we do it
We remove loose mortar, build the crown back with a proper overhang and drip edge, and slope the surface so water sheds toward the outside instead of pooling near the flue.
What Chimney Repair Costs in Monrovia
| Item | Typical range in Monrovia |
|---|---|
| Chimney cap installation or replacement | $160 – $340 |
| Chimney flashing repair | $225 – $600 |
| Chimney crown repair | $600 – $1,700 |
These are typical ranges for Monrovia homes. The written estimate sets the final price after we’ve seen the flue and the masonry.
How do I know if my Monrovia chimney needs a new liner or just a sweep?
You’ll know after a camera inspection. We run a camera through the flue before and after sweeping, so if there are cracked tiles or missing mortar, you’ll see the footage yourself. In older Monrovia chimneys, liner damage is common enough that we always check. Call (833) 362-8107 to book an inspection.
Can I put off chimney repair until next year?
Some repairs can wait. A small crown crack or minor flashing gap won’t fail overnight, but a cracked liner should be addressed before you burn again. Flue gases leaking through a broken liner is a carbon monoxide risk. We’ll tell you plainly if a repair can safely wait, and show you the camera footage that backs up what we’re recommending.
Brands We Service in Monrovia
We work with Olympia Chimney, Famco, and Copperfield products on Monrovia chimneys, and we keep common caps and flashing components ready so most repairs don’t wait on a parts order.

In Monrovia, the two things that push cost up are access and liner condition. A steep foothill roof or a chimney that’s hard to reach from a ladder adds labor, and a liner with multiple offsets makes installation more involved than a straight vertical run. Every job gets a written estimate after we inspect, and that’s the price you approve before work starts. No surprises at the end.

What Monrovia Customers Say

- Ruben Mendoza"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
- Elena Salazar"Drop cloths everywhere, HEPA vac, and not a speck of soot on the carpet. I'd been dreading the mess for nothing."
