Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Inspection Across Monrovia
A chimney inspection in Monrovia typically costs $189 to $389 depending on the level of detail required, and most appointments take 45 to 90 minutes on site. Our crews know the difference between a 1920s Craftsman flue near Old Town and a mid-century ranch fireplace on the flatlands, because we inspect both every week. If you’re in Monrovia and want a straight answer about the condition of your chimney before burning season, call (336) 863-3889 and we’ll give you a written price before anyone sets foot in your home.
Scheduling is coordinated from our Los Angeles office, but the technicians who arrive at your Monrovia door are the ones running the camera and documenting every finding. You’ll know the technician’s name and see their photo before we arrive. No surprises at the door. No surprises on the invoice.
Why Alcott Chimney Sweep Is Monrovia’s Preferred Chimney Inspection Company
Ruben Castellano has run Alcott Chimney Sweep since 2002 with a simple rule: show the homeowner the evidence. When we run a Chimney Inspection in Monrovia, you receive a camera report with photos of the inside of your flue, not a verbal summary you have to trust. That matters in a city where many chimneys date back to the original Craftsman-era buildout and haven’t been opened up in decades.
Our technicians are background-checked and identity-verified under the Threshold Standard before they ever step onto a Monrovia property. They arrive in uniform, show a photo ID badge at the door, and hand you a written price before any work begins. Every repair carries a written guarantee. If the repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every Monrovia job we complete.
We answer our phones with a live person around the clock. If you smell smoke at 11 p.m. in a house north of Foothill Boulevard, you’ll talk to a human, not a voicemail box.
Chimney Flue Inspection in Monrovia
A Chimney Flue Inspection in Monrovia is the process of examining the interior passage that carries smoke and combustion gases from your fireplace or wood stove to the outside. We inspect the flue with a camera system that captures the condition of the liner, mortar joints, and any obstructions, so you see exactly what we see. Homeowners north of Foothill Boulevard burning wood stoves as primary heat build heavy third-degree creosote glaze that a standard brush cannot remove, which means a sweep without a full camera inspection misses the tar-glazed liner entirely. A Level 1 flue inspection in Monrovia typically runs $189 to $249; a Level 2 with camera documentation runs $289 to $389.
What the Camera Shows
The camera feed reveals cracks, spalling, hidden flue breaches, and creosote accumulation that an unaided visual check cannot see. On Monrovia’s older masonry chimneys, we regularly find deteriorated mortar joints behind intact-looking fireboxes. You get the photos. You make the call on repairs with evidence in hand.
When to Book One
Book a flue inspection before your first burn of the season, after any chimney fire, or before you buy a home in Monrovia. Real estate transactions in the pre-WWII neighborhoods around Old Town frequently turn up flue liner issues that a standard home inspection misses. We’ve been called in after those inspections more times than we can count.
Chimney Fire in Monrovia
A Chimney Fire in Monrovia starts when creosote deposits inside the flue ignite, and in foothill parcels adjacent to the Angeles National Forest boundary, the stakes are higher than almost anywhere in the San Gabriel Valley. Santa Ana wind events channel through the foothills and create strong downdrafts that dislodge creosote and carry wildfire embers into uncapped or screen-deficient flues. Our post-fire inspection process documents the damage with camera evidence, determines whether the liner survived, and gives you a written report you can file with your insurance company.
After a Fire Event
Chimney fires don’t always roar. Often they sound like a low rumble or a freight train in the flue for a few seconds and then go quiet, leaving cracked liners and compromised mortar behind. If you suspect any fire event, stop using the fireplace immediately and call us. We’ll run a Level 2 inspection and show you exactly what happened inside.
Preventing the Next One
For Monrovia homeowners burning wood as primary heat, we recommend a sweep and inspection at least once per burning season, and twice annually for stoves used daily from November through March. Third-degree creosote glaze builds fast in high-use stoves, especially with the dry, resinous woods common in the foothill communities. A $189 inspection is far cheaper than a liner replacement, and far safer than a chimney fire.
Trusted Brands We Service in Monrovia
We install and service professional trade materials including Olympia Chimney, DuraFlex, and Copperfield products, the same brands chimney professionals specify rather than box-store substitutes. We keep parts on our trucks for the systems most common in Monrovia homes, which means faster turnaround on liner repairs and crown rebuilds for local customers. When your DuraFlex stainless liner needs assessment or your Copperfield cap has seen better days, we can usually evaluate and quote on the first visit.
Common Chimney Inspection Problems We See in Monrovia Homes
- Missing or crushed spark arrestors. Homeowners north of Foothill Boulevard toward the Angeles National Forest boundary often have no spark arrestor at all, or a screen so corroded it no longer functions. That’s a direct violation of California Health & Safety Code §13114 on VHFHSZ parcels.
- Third-degree creosote glaze in wood stove flues. Daily wood burning creates a hard, tar-like glaze that standard brushes cannot remove. If your Monrovia foothill home uses wood as primary heat, a sweep without a full inspection misses the most dangerous buildup.
- Spalling mortar and cracked clay tiles. The unreinforced brick chimneys built in the 1910s through 1940s near Old Town and the Shamrock corridor are prone to deteriorating mortar joints and flue liner cracks that hide behind intact fireboxes.
- Bird and squirrel nests in unused flues. Long dry stretches between infrequent winter fire use invite animals into those older Craftsman-era chimneys. We find nesting debris in Monrovia flues regularly, and it’s a fire and carbon monoxide hazard until removed.

FAQs About Chimney Inspection in Monrovia
Yes. Any Monrovia parcel inside California’s Very High Fire Hazard Severity Zone is legally required to have a UL-listed spark arrestor on every chimney, per California Health & Safety Code §13114. That includes most of the residential area north of Foothill Boulevard toward the Angeles National Forest boundary. Our routine inspections double as a compliance check; if yours is missing or crushed, we’ll document it and quote the repair. Call (336) 863-3889 and we’ll confirm your parcel’s status during the inspection.
Homes using wood stoves as primary heat in Monrovia’s foothill neighborhoods build heavy third-degree creosote glaze far faster than occasional-use fireplaces in flatland cities. The dense, dry wood common in the San Gabriels combined with daily use means a safe burning interval here is closer to six months than twelve. We recommend an inspection at the start of each burning season and a second sweep mid-winter for daily-use stoves. Call (336) 863-3889 to schedule before the first cold snap.
The Eaton Fire of January 2025 destroyed neighboring Altadena just miles west of Monrovia, and its impunity moved through the same foothill interface that defines Monrovia’s northern edge. The urgency is direct: ember transport into uncapped or screen-deficient flues is a real ignition vector, and Santa Ana winds channel through the San Gabriel Valley in exactly the way that spreads it. A chimney inspection here is now a fire-safety investment, not routine maintenance. Call (336) 863-3889 to get ahead of the next wind event.
A Level 2 inspection covers everything in a Level 1 plus full camera documentation of the entire flue interior, attic and crawlspace access points, and exterior chimney structure evaluation. On a 1920s Craftsman near Shamrock Avenue or Old Town, that typically means identifying spalling mortar joints, cracked clay-tile liners, and hidden flue breaches behind intact fireboxes. You receive the camera footage and a written report. Call (336) 863-3889 for a quote on a Level 2 inspection for your Craftsman home.
Yes, and it happens more often in Monrovia than in flatland San Gabriel Valley cities because the long dry stretches between winter fires leave flues quiet and inviting. The older Craftsman-era chimneys without caps are especially prone. Nesting debris blocks the flue, creates carbon monoxide risk, and becomes kindling for the next chimney fire. An inspection with a camera shows exactly what’s in there. Call (336) 863-3889 and we’ll document it before you burn.
One Local Insight That Matters for Monrovia Homeowners
Monrovia’s northern foothill parcels sit inside California’s Very High Fire Hazard Severity Zone, which makes a UL-listed spark arrestor a legal requirement on every chimney. That means a routine Chimney Inspection here doubles as a mandatory compliance check that flatland San Gabriel Valley homeowners almost never face. Our tech ran a Level 2 inspection on a 1920s Craftsman near Shamrock Avenue and found the original unreinforced brick chimney had spalling mortar joints, a cracked clay-tile flue liner, and a crushed, corroded screen with no spark arrestor at all, a direct Health & Safety Code §13114 violation for that VHFHSZ parcel. We documented the liner damage, installed a DuraFlex stainless flue liner with a UL-listed arrestor, rebuilt the crown, and the homeowner has been using their wood stove as primary heat with a clear, code-compliant flue ever since.
That’s the difference between an inspection company that knows Monrovia and one that’s just passing through. We know which parcels carry the code burden. We know what the Eaton Fire changed about how seriously foothill homeowners take ember risk. And we know that Craftsman-era unreinforced brick chimneys with deteriorating mortar joints and aging clay-tile liners go uninspected for decades, leaving spalling and hidden flue breaches behind intact-looking fireboxes.
