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 starts with understanding what 90 years of earthquakes and Santa Ana winds do to a masonry flue. Many of the Craftsman and Spanish Colonial homes climbing toward the San Gabriel foothills still run their original clay-tile liners, and we routinely find cracked tiles and crumbled mortar crowns that look fine from the ground but fail the moment heat hits them. Sherwood Chimney Sweep handles the full chimney system in Monrovia, from the annual sweep to structural repair, with one number to call: (833) 589-8498.
Why Monrovia Homes Are Different
Monrovia sits where the San Gabriel Mountains meet the valley floor, and that location shapes the chimney work we do here more than any other factor. The homes in the Historic District and along Foothill Boulevard’s older streets date from 1900 to 1939, and their chimneys were built to a standard that simply predates modern seismic code. Decades of minor earthquake movement, plus the dry Santa Ana winds that rake the foothills each fall, leave behind hairline cracks in flue tiles and loosened mortar joints. What starts as a cosmetic crack opens into a pathway for heat and carbon monoxide once a fire is lit.
Monrovia’s climate adds a second wrinkle. The long dry summers mean fireplaces sit dormant for eight or nine months, and that idle stretch is exactly when soot settles, creosote hardens, and birds or squirrels build nests in uncapped flues. By the time the first cool night arrives in November, a chimney that was “fine last winter” may be carrying a season’s worth of debris and internal damage. The foothill humidity swings, mild as they are, also push moisture into old brick and mortar crowns, accelerating spalling on homes in the 91016 and 91017 ZIP codes.
Styles & brands we work with





Our Main Monrovia Services
Most Monrovia homeowners reach out to us for one of two reasons: a chimney that has not been swept in recent memory, or a dryer vent that has never been inspected at all. Both are fire-prevention work, and both live under the same roof at Sherwood Chimney Sweep.
Chimney Sweep in Monrovia
A chimney sweep in Monrovia is not just about removing soot. On an older foothill home, the sweep gives us the first real look at what the flue has been through since your last burn season. We remove creosote and debris, check the cap and crown, and flag any cracking or liner wear before it becomes a repair bill. For homes in the Historic District with original masonry flues, that inspection step matters as much as the cleaning itself. See how we approach the full job on our Chimney Sweep in Monrovia page.

Dryer Vent Cleaning in Monrovia
Dryer vent cleaning in Monrovia belongs in the same conversation as chimney work because lint is the leading cause of household dryer fires, and older Monrovia homes often run long vent runs through tight crawl spaces or up through interior walls. We pull the built-up lint, check the termination point outside, and make sure the vent is moving air the way it should. It is fire prevention, not just cleaning. Details are on our Dryer Vent Cleaning in Monrovia page.

Chimney Repair in Monrovia

Chimney repair in Monrovia is where the foothill housing stock really shows its age. The 1920s and 1930s bungalows that define the Historic District were built with clay-tile liners and mortar crowns that have absorbed a century of seismic movement, Santa Ana buffeting, and winter smoke. What we find most often is not a single dramatic failure but accumulated damage: a cracked tile here, a loosened mortar joint there, a crown that has started to absorb water. This is the work we cover under our Chimney Repair service, and in Monrovia it frequently saves a chimney that a less experienced outfit would write off as a full rebuild.
Chimney Cap Installation
Signs you need it
If you hear birds or squirrels inside the flue, or if water has been dripping into the firebox after rain, the chimney is uncapped or the existing cap has failed.
What it costs in Monrovia
Chimney cap installation in Monrovia typically runs $150 to $450, depending on the flue size and whether the crown needs prep work first.
How we do it
We measure the flue opening, secure the cap to the crown with stainless hardware, and verify the mesh size keeps animals out without restricting draft.
Chimney Liner Installation
Signs you need it
Crumbling clay tile pieces in the firebox, a persistent smoky smell after fires, or a camera inspection showing cracked flue tiles all point to a failed liner.
What it costs in Monrovia
Chimney liner installation in Monrovia ranges from $2,500 to $5,000 for a typical single-story home, with taller foothill chimneys running higher.
How we do it
We run a camera to document the damage, size a DuraFlex stainless liner to the flue, and install it with proper insulation and top and bottom terminations.
Chimney Crown Repair
Signs you need it
A crown with visible cracks, a crumbled or missing top surface, or water staining on the ceiling near the fireplace typically means the crown has stopped shedding water.
What it costs in Monrovia
Chimney crown repair in Monrovia runs $400 to $900 for a standard masonry crown, depending on how much of the old crown must be removed.
How we do it
We remove the deteriorated surface, build the crown back up with a proper slope, and seal it so water drains away from the flue instead of pooling and freezing.
What Chimney Repair Costs in Monrovia
| Item | Typical range in Monrovia |
|---|---|
| Chimney cap installation | $150 – $450 |
| Chimney crown repair | $400 – $900 |
| Chimney liner installation | $2,500 – $5,000 |
Can a cracked chimney be repaired or does it need a full rebuild?
Most cracked chimneys can be repaired without a full rebuild. We use HeatShield ceramic resurfacing to restore deteriorating flue liners from the inside, which often eliminates the need for a tear-out on Monrovia’s older foothill homes. Call (833) 589-8498 for a camera-based assessment.
How long does chimney repair take in Monrovia?
Most cap and crown work is finished in a single visit, usually half a day. Liner installation takes a full day, sometimes longer on taller foothill chimneys that require extra staging or roof access care. We schedule around Monrovia’s burn season so you are not without a fireplace in November.
Brands We Service in Monrovia
We stock and install parts from Gelco, Olympia Chimney, Famco, and Copperfield, the same professional-trade supply chain used by certified chimney engineers. Most common caps, crowns, and liner components are in our inventory for Monrovia jobs, which keeps turnaround short. See the full list on our brands page.

What pushes a Monrovia quote higher is usually chimney height and roof pitch. Two-story foothill homes with steep roof lines require more staging and safety rigging, and that shows up in the labor line. What it does not change is the flat-price promise: we agree on the number before any work begins, and the camera inspection report is included so you see exactly what you are paying for.

What Monrovia Customers Say
"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
— Jodi Parker"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."
— Ruben Flores"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
— Nabil Saleh
