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 Montclair, CA
Chimney repair in Montclair usually means finding the original 1950s or 1960s clay flue behind a gas log set that was retrofitted decades ago without updating anything behind it. That’s the call we get most often: a fireplace that was decorative for forty years, converted to gas, and now shows spalling brick or a cracked crown. Chestnut Chimney Sweep approaches every Montclair job as a diagnostic visit first. The housing stock here is dense, consistent, and predictable, which means we know what we’ll find before we get on the roof. If you need chimney repair or a full sweep, call (855) 360-4975.
Why Montclair Homes Are Different
Most of Montclair’s single-family homes went up in the 1950s through the 1970s, built as tract houses and small ranch-style stucco boxes with masonry fireplaces. A lot of those fireplaces were decorative from day one. They were installed because a fireplace sold the house, not because anyone planned to heat with it. What that means today is a city full of original clay-tile liners, uncapped crowns, and chimneys that have never once been swept. The deferred maintenance is the job. We’re rarely doing routine seasonal cleaning in Montclair; we’re discovering what was never touched.
The flat, compact footprint of Montclair and its position where the San Gabriel Valley foothills meet the Inland Empire create a wind corridor that moves smoke and debris differently than nearby Pomona or Claremont. Santa Ana events push dust, leaves, and embers into caps and crowns. Hot, dry summers bake creosote inside older flues until it’s brittle and flaky, which actually makes it easier to remove but also means it’s more likely to have already cracked the liner beneath. Most Montclair chimneys sit unused for months between burn days, enough time for birds to nest, soot to cake, and problems to settle in undetected.
One thing we see constantly in Montclair’s older tracts: a 1960s fireplace retrofitted with a gas log set, with the original unlined or cracked clay flue still behind it. The appliance changed. The code never did. Nobody pulled a permit for the conversion, so nobody inspected the flue. Gas burns cooler than wood but produces acidic moisture, and that moisture eats old clay from the inside out. It’s a quiet failure, and a common one here.
Styles & brands we work with





Our Main Montclair Services
Two services dominate the calls we get from Montclair homeowners: chimney sweeping for fireplaces that haven’t been opened in years, and dryer vent cleaning for the 1950s and 60s laundry rooms with long runs and lint-packed ducts.
Chimney Sweep in Montclair
A chimney sweep in Montclair usually starts with figuring out whether the fireplace has ever been swept at all. With so many homes built in the 60s and 70s and used lightly for decades, the answer is often no. Creosote in these older flues is typically dry and crusted from Inland Empire heat, which makes it more brittle, but it’s still fuel against a clay liner that may already be compromised. Spanish-tile roofs on many Montclair homes make rooftop access trickier than on a simple asphalt roof, so we plan for careful footing and protected surfaces. For the full scope of what a Montclair sweep involves, see Chimney Sweep in Montclair.

Dryer Vent Cleaning in Montclair
Dryer vent cleaning in Montclair is a fire-safety service, not a convenience add-on. Many homes here have laundry rooms tucked into the center of the house, which means the vent run can be long, bent through walls, and packed with lint by the time we arrive. If a dryer is taking two cycles to finish a load, the vent is already restricted. That’s true everywhere, but in Montclair’s older homes the original vent routing often was never designed for modern high-efficiency appliances. We treat the vent the same way we treat a flue: inspect, clean, verify flow. Learn more at Dryer Vent Cleaning in Montclair.

Chimney Repair in Montclair

Most chimney repair work in Montclair is the direct result of a 1960s or 70s home that has lived through fifty Inland Empire summers with an original clay liner and no crown cap. The heat and Santa Ana winds dry everything out, the chimney sits unused between occasional burn days, and small cracks become big ones without anyone noticing. We also see a lot of gas log conversions that were done without re-lining the flue, leaving the original clay to handle moisture it was never meant to see. Whether it’s a cap, a crown, flashing, or a full liner, we specify the right product for the system, by name. That’s the Chimney Repair approach Chestnut is built on.
Chimney Cap Installation
Signs you need it
Rain streaks inside the firebox, bird sounds from the flue, or a missing or rusted cap.
What it costs in Montclair
New cap installation typically runs $260 – $650, including the cap and mounting hardware.
How we do it
We measure the flue, match the cap to the liner profile, secure it with the correct fasteners, and verify draft before leaving.
Chimney Liner Installation
Signs you need it
Flaking clay in the firebox, a gas smell when the fire is off, or a chimney sweep’s camera showing cracks, gaps, or missing liner sections.
What it costs in Montclair
Expect $1,900 – $3,800 for a full liner job; we will also show you HeatShield restoration as a lower-cost alternative when the existing liner still has most of its structure.
How we do it
We run a camera first to see exactly what’s there, then either install a properly sized stainless liner or carry out a HeatShield resurfacing, depending on damage and budget.
Chimney Flashing Repair
Signs you need it
Water stains on ceilings near the chimney chase, damp drywall in the attic, or visible gaps between roof and brick.
What it costs in Montclair
Flashing repair in Montclair typically runs $260 – $650, depending on whether we’re rebedding or replacing the flashing.
How we do it
We cut back the old sealant, inspect the roof-to-chimney junction, and reseal or replace the flashing so water cannot track down the brick.
What Chimney Repair Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Chimney cap installation | $260 – $650 |
| Flashing repair | $260 – $650 |
| Full liner installation | $1,900 – $3,800 |
How much does a chimney liner cost in Montclair?
Full liner installation runs $1,900 – $3,800. If the old liner still has structural integrity, HeatShield restoration typically costs far less and adds years of life. Call (855) 360-4975 for a quote specific to your flue.
Do I need a new liner if I switched from wood to gas?
Not always, but often. Many Montclair homes converted to gas without re-lining, leaving original clay to handle acidic gas exhaust. We inspect by camera first and only recommend replacing what is actually failing.
Brands We Service in Montclair
We stock and install HeatShield, Gelco, Olympia Chimney, and Famco parts for Montclair homes. No hardware-store substitutes. Most common caps and flashing components are on the truck, so a straightforward repair often completes the same day. See our brands for the full list.

What Montclair Customers Say
"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Marisol Salazar"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
— Javier Garcia"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."
