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 means dealing with what a century of Craftsman bungalows, Spanish Colonial Revivals, and hillside ranch homes actually throw at you: crumbling mortar crowns on original clay-tile flues, leaky flashing around rooflines that bake in the rainless summer and then get hammered by Santa Ana winds, and narrow flue dimensions that were never intended for modern wood-burning inserts. Firebrick Chimney Sweep does the sweep and the structural repair, so a cracked crown or deteriorated liner found during cleaning gets fixed by the same company that found it. Call (866) 520-4943 for a full inspection and a straight answer.
Why Monrovia Homes Are Different
Monrovia sits where the flat grid south of Foothill Blvd gives way to canyon lots at the base of the San Gabriel Mountains, and that change in terrain changes everything about chimney work. Homes in the foothill blocks off Canyon Blvd and the steep streets climbing toward the mountains burn far more wood than the valley floor because they sit in cool mountain shade, and their chimneys collect what the wind drives in: oak and eucalyptus litter, seed pods, ash, and grit. A sweep in those neighborhoods is often less about creosote inside the flue and more about clearing a packed spark arrestor and cap before fire season.
The housing stock compounds it. Most of Monrovia’s core dates from the 1900s through the 1930s, and those Craftsman and Spanish Colonial Revival homes still run original brick or clay-tile chimneys with narrow flues that were sized for open-hearth fires, not sealed inserts. The hillside neighborhoods mix in mid-century ranch homes with prefab metal fireboxes set against canyon slopes. Both types share the same local failure pattern: months of dry, creosote-heavy sitting followed by sudden high-wind downdrafts that push smoke back into a house whose chimney only gets used during cold snaps.
Styles & brands we work with
Our Main Monrovia Services
Two services account for the majority of what Monrovia homeowners call us about: the annual or bi-annual sweep that clears creosote and mountain-littoral debris, and dryer vent cleaning that addresses one of the leading causes of residential house fires. Each has its own Monrovia page with full detail.
Chimney Sweep in Monrovia
A Monrovia chimney sweep is as much about what the wind puts on top of your chimney as what burning puts inside it. In the foothill neighborhoods off Canyon Blvd, oak and eucalyptus litter packs into chimney caps and spark arrestors every fall, and a sweep that skips the cap leaves a Very High Fire Hazard Severity Zone home with an ignition source waiting. We clear the cap, brush the flue, and inspect the system, with the repair capability to fix what we find. Full detail on our Chimney Sweep in Monrovia page.
Dryer Vent Cleaning in Monrovia
Dryer vents and chimneys share the same fundamental risk: restricted, dirty ventilation that becomes a fire. In Monrovia’s older homes, dryer vents often run long distances through walls and crawlspaces, collecting lint that no big-box brush reaches. We clean the vent from the dryer to the exterior termination and check the termination flap, because a blocked flap is what pushes exhaust back into the home. Full detail on our Dryer Vent Cleaning in Monrovia page.

Chimney Repair in Monrovia
Chimney repair in Monrovia typically falls into two categories: water damage to the crown and flashing on century-old masonry chimneys, and flue deterioration that shows up when a homeowner or home inspector finally looks past the damper. The rainless summers and sudden Santa Ana events do predictable things to mortar and metal. We handle the repair ourselves, using professional-grade materials from the chimney trade, not whatever’s stocked at the hardware store. See our Chimney Repair service hub for the full scope.
Chimney Cap Installation
Signs you need it
You see oak or eucalyptus debris inside the firebox, hear birds or animals inside the chimney, or get rain down the flue during winter storms.
What it costs in Monrovia
Chimney cap installation in Monrovia typically runs $150 to $450, depending on flue size and whether a custom cap is needed for an odd-sized clay tile top.
How we do it
We measure the flue opening, select a properly sized cap with spark arrestor mesh from a professional-grade supplier, and mechanically fasten it to the flue or crown so it won’t lift in Santa Ana winds.
Chimney Flashing Repair
Signs you need it
You notice water staining on the ceiling near the chimney, damp brick after rain, or rusted metal visible where the chimney meets the roofline.
What it costs in Monrovia
Chimney flashing repair in Monrovia typically runs $300 to $800, with the higher end covering stepped flashing replacement where the chimney meets a steep canyon-side roof pitch.
How we do it
We remove the old flashing, check the underlying roof deck and brick for damage, and install new step and counter flashing that moves water off the chimney instead of into the chase.
Chimney Crown Repair
Signs you need it
The concrete or mortar cap at the top of your chimney has visible cracks, spalling, or missing sections, especially after a dry summer followed by winter rain.
What it costs in Monrovia
Chimney crown repair in Monrovia typically runs $400 to $1,200, depending on whether we can seal and resurface the existing crown or need to pour a new one.
How we do it
We assess the crown’s condition, remove loose material, and either apply a professional-grade resurfacing compound or form and pour a new concrete crown with proper overhang and drip edges.
Chimney Liner Installation
Signs you need it
Your home inspector flagged a cracked clay tile liner, or you see flue tile fragments in the firebox, or smoke backs up into the house during high-wind downdrafts.
What it costs in Monrovia
Chimney liner installation in Monrovia typically runs $2,500 to $5,500, depending on whether a stainless steel liner or a HeatShield ceramic resurfacing treatment is the right fit for your flue.
How we do it
We run a camera inspection to confirm the liner’s condition, size the new liner to your appliance and flue dimensions, and install either a professional-grade stainless liner or apply HeatShield’s ceramic resurfacing system.
What Chimney Repair Costs in Monrovia
| Item | Typical range in Monrovia |
|---|---|
| Chimney cap installation | $150 – $450 |
| Chimney flashing repair | $300 – $800 |
| Chimney crown repair | $400 – $1,200 |
Do I really need to fix a cracked crown right away?
A cracked crown lets water into the brick and mortar below it, and Monrovia’s winter rain followed by Santa Ana dry spells accelerates spalling. If left alone, a $600 crown repair becomes a $3,000 masonry rebuild. Call (866) 520-4943 to have it looked at.
Can you repair a chimney that a home inspector flagged?
Yes. Camera inspection comes with the repair scope, so you see exactly what the inspector saw. We quote based on that footage, and we can send the report to your agent or insurance carrier if needed. Call (866) 520-4943 to schedule.

FAQs About Chimney Company in Monrovia
We prioritize fire-season cap and spark arrestor clearings in Monrovia’s foothill ZIP codes, because a packed cap in the Very High Fire Hazard Severity Zone is a real ignition risk. Call (866) 520-4943 and we’ll get you scheduled quickly.
Most chimney repairs, including cap installation, crown resurfacing, and flashing repair, don’t require a Monrovia city permit. Liner installation or any structural masonry rebuild may, and we’ll tell you if that’s the case before work begins.
Late summer or early fall, before the Santa Ana winds kick in, is the smartest window. Chimneys sit dry and creosote-heavy through the rainless summer, and the first cold snap with high wind is when blocked flues and packed caps become obvious. Book before that.

What Monrovia Customers Say
"Good work. The written inspection report took about a week to arrive after I asked for it, which was slower than I expected."
— Luis Hernandez"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
— Steve Novak"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
— Scott Ziegler
