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.

Call (336) 863-3889 and we’ll give you a written price before any work starts.
We know Montebello’s houses. The postwar tracts off Beverly Boulevard and Whittier Boulevard, the Spanish-style stucco homes along the hills near Grant Rea Park, the ranch layouts throughout the 90640 zip code. When we pull up to a Montebello address, we already have a good guess what the fireplace looks like inside, because we’ve serviced hundreds of them in this city. That local experience means faster diagnosis and fewer return trips.
Why Alcott Chimney Sweep Is Montebello’s Preferred Gas Fireplace Repair Company
Ruben Castellano runs our gas fireplace repair operation, and the standard he set in 2002 still shapes every job we take in Montebello. Every technician who walks up your driveway is background-checked, identity-verified, and sent to you by name and photo before the visit. That’s the Threshold Standard, and it’s not an optional upgrade. You’ll see who’s coming before we arrive, and they’ll show you a photo ID badge at the door. Every time, no exceptions.
Our Gas Fireplace Repair team has spent two decades working on the exact fireplace configurations Montebello homeowners inherited: original 1950s masonry chimneys with 1980s and 1990s gas log inserts dropped in without proper flue work. We’re not learning your house’s quirks on the job. We already know them. That’s why Montebello customers call us back when the next issue shows up, and why our written guarantee on every repair actually means something: if the repair fails within the coverage period, the second visit is free.

Our Gas Fireplace Repair Services in Montebello
Gas Fireplace Insert Servicing and Flue Right-Sizing
Montebello’s housing stock has a specific problem we see constantly: a 1950s wood-burning fireplace with a 1980s or 1990s gas log insert dropped in, while the original single-wythe brick flue was never relined or correctly capped for a gas appliance. The flue is oversized for the low-BTU burner, which means moisture condenses inside the chimney every winter, eroding mortar and creating a carbon monoxide path that goes unnoticed because the fireplace “works fine.” We service the insert, measure the flue, and right-size the liner so the chimney actually matches the appliance venting through it.
Level 1 and Level 2 Chimney Inspection for Gas Appliance Changeouts
If you’re switching a wood-burning fireplace to gas in Montebello, or if your gas insert was installed decades ago and never inspected, a Level 2 inspection is the right call. We camera-scan the flue interior, check the mortar joints, and document everything with photos you can see for yourself. We work with Olympia Chimney and DuraFlex liner systems, and we’ll tell you plainly whether the existing flue can be relined or needs more involved work. Nothing gets recommended without camera evidence in front of you.
Firebox, Damper, and Smoke Chamber Repair
Montebello’s original masonry fireboxes are now 60 to 75 years old. Mortar joints fail, dampers rust open or shut, and smoke chambers crumble where Santa Ana wind-driven debris has been sitting for months. We rebuild fireboxes with proper refractory materials, replace damper assemblies, and resurface smoke chambers with HeatShield. If we open up a firebox in Montebello and find what our techs find on a regular basis, you’ll see the photos before we touch anything.
Chimney Cap Replacement and Santa Ana Wind Protection
Montebello sits directly in the path of Santa Ana events that push hot, dry air at high velocity from the northeast. We routinely find chimney caps torn off, bent, or missing entirely across Montebello neighborhoods, which leaves the flue open to birds, debris, and rain. We install Copperfield stainless caps sized to your flue, and we torque them down properly so the next wind event doesn’t leave you exposed again.

Trusted Brands We Service in Montebello
We stock and install professional trade materials, not box-store substitutes. When we reline a Montebello flue, we’re using DuraFlex liner systems. When we replace a cap, it’s Copperfield stainless. When we repair a damper or firebox component, we’re reaching for Olympia Chimney or Famco hardware. These are the brands chimney professionals specify, and we keep the common sizes and fittings on our trucks so a Montebello repair doesn’t stall waiting on a parts shipment.
Common Gas Fireplace Repair Problems We See in Montebello Homes
- Oversized, unlined flues on 1980s-90s gas log retrofits. The original single-wythe masonry flue was built for a wood fire, not a low-BTU gas burner. The mismatch causes condensation, mortar erosion, and CO risk that hides behind a working-looking fireplace.
- Santa Ana wind damage to caps and dampers. High-velocity northeast winds bend or tear off aging chimney caps, then force ash and soot back down the flue. A clogged damper is a carbon monoxide spill waiting to happen.
- Bird and rodent nesting in the smoke chamber. Eight to ten months of idle time each year means starlings, sparrows, and roof rats fill the smoke chamber with nesting material. Homeowners skip the inspection because the fireplace “works fine,” and the flue gets progressively more blocked.
- Crumbling firebox mortar from decades of wet-dry cycles. Montebello’s seasonal swing, heavy rain December through March then near-zero humidity through fall, spalls the firebox mortar in original masonry chimneys. Once the joints fail, heat and gases escape into the wall cavity where they don’t belong.

FAQs – Gas Fireplace Repair in Montebello
It matters because your chimney was built for wood, not gas. The original single-wythe brick flue is oversized for a low-BTU gas log insert, which means moisture condenses inside the flue every winter, slowly eroding the mortar and creating a path for carbon monoxide to seep into your living space. You won’t see it, and the fireplace will keep working until it doesn’t. If you’re in Montebello and you’ve never had the insert inspected, call (336) 863-3889 and we’ll camera-scan the flue and show you exactly what’s there.
Every year. The irony is that Montebello fireplaces sit idle 8 to 10 months a year, and that idle time is when birds nest, debris accumulates, and Santa Ana wind damage goes unnoticed. A Level 1 inspection takes under an hour and catches the blockages before they become carbon monoxide problems. Call (336) 863-3889 to book one.
No. A missing or damaged cap leaves your flue open to debris, birds, and downdrafts, and running a gas appliance through a compromised flue is exactly how CO spills into a living room. We’ll get a technician to your Montebello home to cap it correctly, but until then, keep the gas valve to the fireplace shut off.
Black staining around the firebox or damper usually means combustion gases are spilling back into the room instead of venting up the flue. In Montebello’s original masonry chimneys, that spill is often caused by a blocked flue, a failed damper, or an oversized flue that can’t maintain proper draft for a gas insert. It’s a carbon monoxide warning sign, not a cosmetic issue. Call (336) 863-3889 and we’ll inspect it before you run the fireplace again.
Yes, and that’s usually the right move. We reline original masonry flues with DuraFlex stainless liners sized correctly for your gas appliance, which fixes the oversized-flue condensation problem without tearing out the chimney. Rebuilding the entire chimney is almost never necessary, and we’ll tell you plainly when it isn’t.
