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 Claremont, CA
Chimney repair in Claremont usually comes down to one thing: masonry that’s been sitting untouched since the Eisenhower administration. We’re Ontario Chimney, and we’ve served Claremont since 2014. Most of our work in the 91711 ZIP code is inspection and relining on original brick and stone fireplaces in Craftsman bungalows and mid-century ranch homes, not heavy creosote removal from winter overuse. The mild Pomona Valley climate means chimneys here decay slowly and quietly, so the damage you can’t see is usually the damage that matters. Call us at (833) 467-7685 when you want a straight answer about what’s actually going on inside your flue.
Why Claremont Homes Are Different
Claremont’s housing stock runs older than most of the San Gabriel Valley. The neighborhoods around the Claremont Colleges and the Village are full of 1920s and 1930s Craftsman homes with original brick fireplaces. Head north or east and you hit the mid-century ranch tracts from the 1950s and 1960s, many of which have unlined flues or aging clay tile liners that were code-compliant six decades ago and aren’t now. That matters because the failure mode here isn’t heavy creosote buildup from nightly fires. It’s slow deterioration: mortar joints eroding inside the flue, clay tiles cracking from decades of thermal expansion, and chimney crowns spalling in the dry heat. Claremont sits in the Pomona Valley with a Mediterranean climate, almost no freezing weather, and fireplaces that get lit a handful of times each winter. When a chimney sits dormant for ten or eleven months a year, moisture, pests, and time do their work unnoticed. Homeowners here care about preserving original fireplace character, especially in the historic districts near the colleges, which means our role is often restoration and compliance more than routine sweeping.
Styles & brands we work with





Our Main Claremont Services
The two calls we get most from Claremont homeowners are chimney sweeping for wood-burning fireplaces and dryer vent cleaning for the laundry room, especially in older homes where the dryer duct runs through a crawlspace or out a roof vent. Here’s what each one involves here.
Chimney Sweep in Claremont
In Claremont, a chimney sweep usually starts with the same question: when was the last time anyone looked inside this flue? Many homeowners buying a 1940s bungalow near the colleges have no record of prior service, and that first inspection often turns up leaf debris from the mature oaks that canopy the Village neighborhoods, old squirrel nesting material, or a clay tile liner that’s spalling and needs attention. We sweep when creosote is the issue, but we also remove blockages and document liner condition with camera inspection. For details on what a sweep includes and what it costs, see Chimney Sweep in Claremont.

Dryer Vent Cleaning in Claremont
Claremont’s older homes frequently route dryer exhaust through long, multi-bend duct runs that terminate on the roof or through a side wall with a louvered cap the homeowner never opens. Lint accumulates faster in those runs than in short, direct-vent systems in newer construction. The National Fire Protection Association has identified failure to clean dryer vents as a leading cause of home fires involving dryers. We treat dryer vent cleaning as standalone fire-safety work, not an upsell. For the full scope, see Dryer Vent Cleaning in Claremont.

Chimney Repair in Claremont

Chimney repair in Claremont is usually about addressing what decades of light use and long dormancy have done to aging masonry. Homes built between the 1920s and 1960s dominate the city, and many of their original brick or stone fireplaces have clay tile liners that are cracked, spalling, or absent entirely. The mild climate masks the problem: because the flue isn’t stressed by heavy winter burning, deterioration progresses slowly and goes unnoticed until an inspection flags it. When we find a liner issue, we show you the camera footage, explain whether it can wait, and walk through the options, which is the same approach we take on every repair, from a rusted chimney cap to a leaking flashing joint. For a fuller breakdown of the repair scope we handle, visit Chimney Repair.
Chimney Cap Installation
Signs you need it
You find leaves, twigs, or nesting material in the firebox, hear rain dripping down the flue, or see rust stains on the damper.
What it costs in Claremont
A new cap with installation typically runs $200 to $600 in Claremont, depending on the cap material and the flue tile size.
How we do it
We measure the flue, select a stainless or copper cap from Famco or Copperfield lines, and secure it to the crown with mechanical fasteners, not caulk.
Chimney Liner Installation
Signs you need it
Your inspection shows cracked or missing clay tiles, or a level-two inspection after a chimney fire reveals damage to the flue walls.
What it costs in Claremont
Relining an existing masonry chimney in Claremont typically falls between $2,500 and $5,500 when we install a DuraFlex stainless steel liner sized to the flue.
How we do it
We measure the full flue run, assess any offsets, install the insulated liner from the top down, and reconnect the appliance or firebox with proper clearances.
What Chimney Repair Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Chimney cap installation | $200 – $600 |
| Chimney liner installation | $2,500 – $5,500 |
| Chimney flashing repair | $350 – $900 |
Two factors push repair prices up in Claremont: access and liner condition. A chimney on a steep-pitch roof with limited staging room costs more to work on than a single-story ranch with a walkable roof slope. And if the clay liner has collapsed in multiple spots, a HeatShield resurfacing or full liner replacement takes longer than a straightforward cap swap.
Do I need to reline my chimney if I only use the fireplace once a year?
Not necessarily, but usage frequency isn’t the only variable. A clay liner that’s cracked or spalling is a hazard regardless of how often you burn because combustion gases can reach combustible framing. The only way to know is a camera inspection.
Can you repair the brick on a 1930s Claremont fireplace without ruining the look?
We match mortar and brick profiles carefully on older Craftsman fireplaces, and we’re used to working in preservation-minded Claremont neighborhoods where homeowners want repair that doesn’t announce itself. We’ll show you options before we touch the masonry.
Brands We Service in Claremont
We install and service the brands chimney professionals actually specify: DuraFlex stainless liner systems, Famco caps and dampers, Copperfield chimney components, and we’re certified applicators for HeatShield ceramic flue resurfacing. See our brands for the full list, and call if you have a chimney with parts from a brand you don’t recognize. We’ll identify what’s on the roof and tell you the right fix.

Access is the biggest price variable in Claremont. Homes in the northern and eastern ranch tracts often have straightforward single-story roof access, while Craftsman bungalows near the colleges with steep gables and mature trees overhead can push a simple repair toward the higher end of the range. Whatever the job, we quote a flat price before any work starts, and the price we agree on is the price you pay.
