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 Hawthorne, CA
Chimney repair in Hawthorne usually starts with a visual inspection that turns up something the homeowner hadn’t noticed: a rusted damper, a cracked firebox panel, a clay tile flue with gaps where mortar used to be. Most of the chimneys we see here were built between 1948 and 1965, and decades of marine-layer moisture have worked on them from the outside while occasional fires have done damage from the inside. We handle the full repair scope, from a new chimney cap to a complete flue relining, so you’re not coordinating between a sweep company and a separate contractor. Call Ontario Chimney at (833) 467-7685 when you want one company from inspection to completion.
Why Hawthorne Homes Are Different
Hawthorne’s 1950s postwar housing boom left thousands of homes with original masonry fireplaces that see little use but deteriorate from coastal salt air and marine layer moisture. The chimneys in Holly Park and Ramona Park were built fast, with clay tile flues and brick fireboxes that were never meant to sit damp for months at a time. Moisture from the marine layer condenses inside the flue, mixes with old soot, and creates a mildly acidic slurry that eats at mortar joints. Metal dampers fare worse: salt air accelerates rust, and we routinely find dampers in Hawthorne that are frozen open, frozen shut, or corroded through entirely.
What this means for homeowners is that a chimney cleaning call often turns into a repair conversation. The mild climate means fireplaces sit unused from April through November, letting moisture and soot settle and do their work. By the time someone lights the first fire of the season, small problems have had months to become bigger ones. We see more spalling brick faces and deteriorated crown mortar in Hawthorne than in inland cities, purely because of the salt and humidity. The good news is that most of this is repairable without tearing the chimney down, and we’ll show you camera evidence of everything before any work is recommended.
Styles & brands we work with
Our Main Hawthorne Services
Two services account for most of what Hawthorne homeowners call us about: routine chimney sweeping and dryer vent cleaning. Both are maintenance that prevents worse problems, and both are handled by the same trained technicians.
Chimney Sweep in Hawthorne
A chimney sweep in Hawthorne is as much about removing corrosive soot and checking for salt-induced damage as it is about creosote removal. Because fireplaces here get used so infrequently, the soot that builds up tends to sit and absorb moisture from the marine layer, turning into a sticky, acidic residue that’s harder to remove and harder on your flue lining than dry, fluffy creosote. Our sweep includes a full visual inspection of the firebox, damper, flue, and exterior crown, with photo documentation so you can see what we see. Read the full breakdown on our Chimney Sweep in Hawthorne page.
Dryer Vent Cleaning in Hawthorne
Dryer vents are a leading cause of house fires, and cleaning them is maintenance, not optional, especially in Hawthorne’s smaller homes where the dryer is often located in a garage or a hallway closet with a long vent run to the exterior. Lint accumulates faster than most homeowners expect, and in Hawthorne’s humid coastal air, that lint can mat together and harden, restricting airflow and forcing the dryer to work harder. This is a standalone fire-safety service for us, not a throwaway add-on. See the full scope on our Dryer Vent Cleaning in Hawthorne page.

Chimney Repair in Hawthorne
Chimney repair in Hawthorne comes down to one recurring pattern: a 1950s clay tile flue, decades of marine air exposure, and a homeowner who just found out during a routine sweep that there’s a crack, a gap, or a missing mortar joint. The problem is rarely the brick chimney shell itself; it’s usually the components inside and on top that have rusted, cracked, or shifted over time. And because most Hawthorne fireplaces sit unused for months at a stretch, these problems don’t announce themselves until a sweep or an inspection catches them. The full scope of what we repair, from caps and crowns to full liner installations, is covered on our Chimney Repair hub.
Chimney Cap Installation
Signs you need it
Water stains on the firebox floor, rusted damper hardware, or evidence of birds or debris inside the flue all point to a missing or failed chimney cap.
What it costs in Hawthorne
A new chimney cap installation in Hawthorne typically runs $300 to $700 depending on the flue size and whether we need to fabricate a custom bracket for an older clay tile flue.
How we do it
We measure the flue opening, install a stainless steel cap with a proper mechanical fastening system, and seal the top of the flue so rain, birds, and salt air can’t get in.
Chimney Flashing Repair
Signs you need it
Water staining on the ceiling near the chimney, damp drywall in an upstairs room, or visible rust and separation where the chimney meets the roofline.
What it costs in Hawthorne
Chimney flashing repair in Hawthorne typically costs $450 to $950, depending on how much of the existing flashing can be salvaged and whether we need to re-seat the counterflashing.
How we do it
We remove the old flashing, inspect the mortar joint behind it, install new step flashing and counterflashing, and seal everything with a high-grade exterior sealant that holds up to coastal moisture.
Chimney Crown Repair
Signs you need it
Cracks in the concrete crown, missing chunks along the edge, or spalling brick just below the crown line.
What it costs in Hawthorne
Chimney crown repair in Hawthorne runs $600 to $1,200, with the higher end covering a full recast of a deteriorated crown rather than a patch job.
How we do it
We clean and prep the existing crown, fill hairline cracks with a flexible sealant rated for chimney use, and recast badly deteriorated crowns with a proper overhanging edge so water drips away from the brick.
Chimney Liner Installation
Signs you need it
Gaps between clay tile sections, flue gas smell in the home, visible cracks in the flue during a camera inspection, or a home inspector flagging the liner before a sale.
What it costs in Hawthorne
A full chimney liner installation in Hawthorne typically runs $3,500 to $7,000 depending on the flue length, the liner material, and whether we need to break out and remove the old clay tiles first.
How we do it
We run a camera inspection to document the condition of the existing flue, then install a properly sized stainless steel liner, usually a DuraFlex system, and connect it to the appliance and the chimney cap.
What Chimney Repair Costs in Hawthorne
| Item | Typical range in Hawthorne |
| Chimney cap installation | $300 – $700 |
| Chimney flashing repair | $450 – $950 |
| Chimney crown repair | $600 – $1,200 |
| Chimney liner installation | $3,500 – $7,000 |
Do I really need a new liner, or can it be repaired?
Sometimes a liner can be resurfaced rather than replaced. If the flue has small cracks or gaps but the structure is sound, HeatShield ceramic resurfacing can restore it for less than a full new liner. We’ll show you the camera footage and give you both options with pricing.
How long does a chimney repair take in Hawthorne?
Most cap, crown, and flashing repairs are done in a single visit of three to five hours. A full liner installation usually takes one full day, and we schedule it around your availability. Call (833) 467-7685 for a straight answer on your specific repair.
Brands We Service in Hawthorne
We work with a curated set of professional-grade materials: DuraFlex liner systems, HeatShield ceramic resurfacing, and Famco caps and dampers, sourced through Copperfield and Olympia Chimney, the two largest professional chimney supply distributors in the trade.

FAQs About Chimney Company in Hawthorne
Most standard sweeps and inspections in Hawthorne can be scheduled within three to five business days. Repair work depends on parts, but caps, crowns, and flashing are usually one visit. Call (833) 467-7685 and we’ll give you a real date, not a window.
Routine sweeping, dryer vent cleaning, and most component repairs like caps, flashing, and crown work don’t require a permit in Hawthorne. If a repair ever crosses into structural territory, we’ll tell you upfront and handle the paperwork. We never hide a permit issue to make a sale easier.
Yes, and in Hawthorne especially. Disused chimneys collect moisture, rust dampers, and crack mortar without anyone noticing. A one-hour inspection with a camera tells you whether the chimney is safe to use or whether you’re better off leaving it cold. We’ll show you the footage either way.
