Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Monrovia
A chimney sweep in Monrovia typically costs $189 – $389, with most homes completed in under two hours. We work throughout 91016 and 91017, from the Craftsman bungalows of Old Town to the foothill streets climbing toward the San Gabriels.

Why Ashwood Chimney Sweep Is Monrovia’s Preferred Chimney Sweep Company
Monrovia homeowners call us because we do more than brush out a flue. Norm Castillo built this company around a simple idea: the person who inspects your chimney should be the same person who fixes it. No hand-off to a separate crew. No broken telephone between the sweep and the repair tech. That matters on homes where a cracked clay tile or corroded cap gets missed by a one-service operator.
We stock professional-grade materials that most sweep-only companies can’t get, including DuraFlex stainless liner systems and HeatShield restoration coatings. When we find a problem, we can usually repair it on the same visit instead of handing you a report and a referral. Our Chimney Sweep service covers the full scope: cleaning, inspection, and repair.
Monrovia’s housing stock is older than most nearby cities. We’ve worked on 1910s bungalows near Myrtle Avenue and 1930s foothill homes where the original clay flue tile is still in place. That experience means we know what to look for before a small crack becomes a flue failure.

Chimney Maintenance in Monrovia
Chimney maintenance in Monrovia is an annual necessity, not an optional extra, because the foothill environment actively works against your masonry. Down-canyon winds above Old Town drive leaves, seed pods, and wildfire ash into uncapped flues every fall. Damp marine-layer mornings degrade mortar and crowns. A chimney that skips maintenance for two or three years often needs hundreds of dollars in repairs that a simple annual visit would have prevented.
A standard maintenance visit in Monrovia runs $189 – $289 and includes a full sweep, a Level 1 inspection, and a written condition report. We check the cap, crown, flashing, flue liner, damper, and firebox. If we find something wrong, you’ll get photos, not just a verbal summary.
What We Inspect on Every Visit
We examine the flue liner for cracks or spalling, the crown for water intrusion, the cap and screen for corrosion or blockage, and the mortar joints on the chimney’s exterior. On Monrovia’s older masonry chimneys, we pay extra attention to the flashing where the chimney meets the roofline, because wind-driven rain finds its way through gaps that look fine from the ground.
When to Schedule Maintenance
Book your sweep in late summer or early fall, before the Santa Ana season. That way, any debris from spring and summer winds is cleared before your first fire, and we can address any cap or screen damage before the real wind arrives.
Chimney Sweep Services in Monrovia
Chimney sweep services in Monrovia handle the creosote, soot, and debris that accumulate in flues serving wood-burning fireplaces and gas inserts. A full sweep costs $189 – $389 depending on the flue’s condition and how long it’s been since the last cleaning. Homes that burn wood regularly should be swept annually. Gas-only fireplaces can often go two years, but the venting still needs an annual visual check.
We use rotary brush systems with HEPA-filtered vacuums, so dust stays out of your living room. Every sweep includes a Level 1 inspection as standard. If you’ve just bought a home or suspect hidden damage, we recommend a Level 2 inspection with a camera run through the flue, which costs $299 – $449 in Monrovia.
Creosote and Soot Removal
Creosote is the tar-like residue that condenses inside your flue when wood smoke cools. It’s flammable, and it builds up fastest in Monrovia homes that burn oak or eucalyptus, both common firewood sources in the foothills. We remove creosote mechanically with wire brushes and, for heavy buildup, chemical treatments that break down the hardened deposits.
Fireplace Cleaning and Inspection
We clean fireboxes, remove ash and debris, check damper operation, and test draft. On gas inserts, we inspect logs, burners, vents, and the flue connection. Many Monrovia homeowners run gas inserts in what were originally wood-burning fireplaces, and those conversions need their own set of checks.

AfterCommon Chimney Sweep Problems We See in Monrovia Homes
- Corroded galvanised caps and flashing. Monrovia’s damp marine-layer mornings and wind-driven rain eat through galvanised metal faster than homeowners expect. We routinely replace caps and flashing on chimneys that looked fine a few years earlier.
- Debris-blocked and bird-nested flues. The down-canyon winds above Old Town drive leaves, seed pods, and wildfire ash into uncapped chimneys. Birds build nests in the fall, and the first cold night produces a smoke-filled living room instead of a working fire.
- Spalling brick and failing mortar on historic chimneys. Craftsman and bungalow homes from the 1900s – 1930s have original masonry that’s absorbed nearly a century of moisture. Gaps in mortar let smoke and moisture move into places they shouldn’t.
- Cracked clay flue tiles on older homes. Clay tiles crack under the thermal stress of heating and cooling cycles. A Level 2 camera inspection often reveals damage invisible from the top of the chimney, and the fix is a stainless steel liner rather than full demolition.

FAQs About Chimney Sweep in Monrovia
Once a year for homes that burn wood, and at least every two years for gas-only fireplaces. Monrovia’s down-canyon winds bring debris into uncapped flues every fall, and the damp mornings degrade mortar, so annual inspections catch problems before they require expensive repairs. Call (833) 805-3229 to schedule your inspection.
Monrovia’s foothill microclimate combines damp marine-layer moisture with wind-driven debris and occasional wildfire ash, all of which accelerate corrosion on galvanised steel components. Stainless steel caps and flashing last far longer and resist the pitting and rust that compromise galvanised parts within a few years.
We see mostly second-degree and third-degree creosote in Monrovia flues, the flaky and hardened tar-like forms that build up when wood stoves and fireplaces run at lower temperatures. Homes burning oak or eucalyptus from the foothills tend to accumulate heavy deposits faster than homes burning softer woods.
Yes. The down-canyon wind pattern above Old Town drives leaves, seed pods, and birds into uncapped flues every single fall. A stainless cap with a mesh screen prevents the blockages and animal entry we see constantly in Monrovia homes, and it also stops rain from entering the flue during winter storms.
A Level 2 inspection runs a camera through the entire flue to document cracks, gaps, spalling, and hidden damage. On Craftsman and bungalow homes with original clay tile liners, we can usually point to the exact tile that’s failing and show you the image. From there, we can often restore the flue with HeatShield or install a DuraFlex liner instead of tearing out masonry. Call (833) 805-3229 to book a Level 2 inspection in Monrovia.
