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 camera inspection, because the foothill homes here don’t fail the way flatland chimneys do. Craftsman bungalows near Old Town often still run original clay-tile flues from the 1920s, while 1950s ranches up toward the mountains have masonry that’s been through decades of Santa Ana wind cycles. The repair we do most often is relining deteriorated flues and replacing mortar crowns that Monrovia’s dry summers and wet winters have cracked. If you’re seeing rust, spalling brick, or smoke backing into the house, call Corona Chimney Sweep at (855) 382-6159 and we’ll put a camera up the flue before recommending anything.
Why Monrovia Homes Are Different
Monrovia sits right at the base of the San Gabriel Mountains, and that changes chimney work in ways that don’t apply in Pasadena or Arcadia. A large share of the city falls inside the Wildland-Urban Interface, which means Monrovia fire inspectors pay real attention to spark arrestors and ember-resistant caps, especially during red-flag wind events. The oak and deodar cedar canopy that makes Monrovia attractive also drops leaves, twigs, and seed debris onto roofs almost year-round. Caps and chimney screens clog within a single season in the foothill neighborhoods above Foothill Boulevard, and a blocked screen does two things: it kills draft and it traps heat.
The housing stock makes this more complicated. The Victorians and Craftsman homes around Old Town (91016) often have original masonry fireplaces with unlined or clay-tile flues. Clay tiles crack after repeated heating cycles, and when they do, the gaps expose the surrounding masonry to heat and creosote. Up in the north foothill neighborhoods (91017), many homes use prefab chimneys or wood-burning inserts that need different clearances and different cap hardware. We carry parts for both types and we know which Monrovia streets have what.
Styles & brands we work with
Our Main Monrovia Services
Most Monrovia homeowners call us for one of two things: an annual sweep or a dryer vent that hasn’t been touched since they moved in. Both are fire-prevention work at the core, and our technicians handle both with the same combustion-venting training.
Chimney Sweep in Monrovia
Monrovia homes that burn wood regularly build creosote faster than most homeowners expect, partly because the same foothill winds that force smoke back down the flue also accelerate creosote drying into its most flammable form. We sweep the full system from firebox to cap, including the smoke chamber and smoke shelf where Monrovia’s older chimneys collect the most debris. We also clear leaf litter and twig buildup from caps and screens, which is a bigger job here than in neighboring flatland towns. Chimney Sweep in Monrovia
Dryer Vent Cleaning in Monrovia
A clogged dryer vent is a fire waiting to happen, and it’s the same technician who sweeps your chimney that runs the rotary brush through the dryer duct. Monrovia’s older laundry rooms often route vents through crawl spaces or up through roofs, which means longer runs and more places for lint to pack in. We don’t hand this off to a less-qualified crew. Lint is fuel, and we clear it completely. Dryer Vent Cleaning in Monrovia

Chimney Repair in Monrovia
Chimney repair in Monrovia is driven by two things: the age of the housing stock and the wind. Early-1900s homes near Old Town usually have masonry fireplaces that were built before modern liner standards, and many of those clay-tile flues have cracked after decades of heating and cooling. When Santa Ana winds blow down from the San Gabriels, they push smoke and embers back into weakened flues and against deteriorated mortar crowns. These are conditions a sweep-only company sees and then refers to someone else. We repair what we find, and every recommendation is backed by camera footage you can see for yourself.
Corona Chimney Sweep has served Monrovia since 2018 and handles the full scope of chimney repair work in-house: liner installation, crown repair, cap replacement, flashing work, and masonry patching. No referrals, no handoff gap. If you want to understand the full scope of our repair capabilities, read our Chimney Repair service page.
Chimney Liner Installation
Signs you need it
You need a new liner if camera inspection shows cracked clay tiles, missing mortar joints, rust on a metal liner, or you see flakes of tile in the firebox.
What it costs in Monrovia
Liner installation in Monrovia typically runs $85 to $110 per foot, with total jobs usually landing between $2,400 and $4,800 depending on flue height and access.
How we do it
We measure the full flue height, break out the old clay tiles where needed, drop a DuraFlex stainless liner down the chase, insulate it, and reconnect the appliance with code-compliant terminations.
Chimney Cap Replacement
Signs you need it
You need a new cap when the existing one is rusted through, missing a spark screen, or so clogged with oak debris that draft is compromised and embers can’t vent.
What it costs in Monrovia
Cap replacement in Monrovia typically costs $300 to $700, depending on flue size and whether you need a standard cap or a custom multi-flue unit.
How we do it
We measure the flue opening, remove the old cap, install a Galvanized or stainless cap with a proper spark screen, and secure it so foothill winds can’t rattle it loose.
Chimney Flashing Repair
Signs you need it
You need flashing work if you see water staining on the ceiling near the chimney, peeling paint on the chimney chase, or damp brick after rain.
What it costs in Monrovia
Chimney flashing repair in Monrovia runs $300 to $650, with full replacement of step and counter flashing at the high end.
How we do it
We cut out the old flashing, inspect the roof deck below, install new step and counter flashing with proper overlap, and seal the joints with a high-temp exterior sealant that holds up to Monrovia’s dry summers and wet winters.
What Chimney Repair Costs in Monrovia
| Item | Typical range in Monrovia |
|---|---|
| Camera inspection | $175 – $300 |
| Liner installation (per foot) | $85 – $110 |
| Cap replacement | $300 – $700 |
Do I really need a new liner, or can it be repaired?
If the damage is limited to hairline cracks and deteriorated mortar joints between clay tiles, HeatShield resurfacing can often restore the flue without full liner replacement. If tiles are collapsed or the liner is rusted through, replacement is the only safe option.
What actually happens if I skip chimney repair in Monrovia?
Cracked flues let heat and combustion gases reach the surrounding masonry, and in a red-flag wind event, that’s an ember and structure-fire hazard. The repair always costs less than the fire. Call (855) 382-6159 for an exact quote after camera inspection.
Brands We Service in Monrovia
We install and service components from DuraFlex, HeatShield, Gelco, and Olympia Chimney. These are contractor-supply-house product lines, not big-box substitutes, and we stock common cap sizes, flashing, and liner components for Monrovia’s typical flue dimensions. Turnaround on brand-specific parts is usually days, not weeks. Read more on our brands.

What pushes price up in Monrovia is roof pitch and the leaf load around your cap. Steep foothill roofs take longer to work on safely, and caps that haven’t been cleared in years take more labor to bring back. Corona Chimney Sweep gives you a flat price before we start, so the number we quote is the number you pay.

FAQs About Chimney Company in Monrovia
The answer depends on scope. Simple sweeps, cap replacements, and flashing repairs don’t require permits. Full liner replacement or structural masonry work often does, and Monrovia’s building department has specific requirements for work in the Wildland-Urban Interface. We’ll tell you before we start whether your job needs paperwork and who handles it.
Most appointments in Monrovia are scheduled within 5 to 10 business days depending on the season. Fall and early winter book out faster as people prep for burning season. If you have a red-flag concern about an uncapped flue, tell us when you call and we’ll prioritize the inspection.
Yes, and we’re careful about it. The Victorians and Craftsman-era homes around Old Town often need liner work done without disturbing original brick or trim. The liner goes inside the existing flue, so the exterior masonry stays intact. The repair is straightforward, and the camera inspection shows you exactly what the old clay tiles look like before anything gets touched.

— Raj Patel"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
— Megan Sullivan"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
