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.

AfterChimney Cleaning in San Dimas, CA
Chimney cleaning in San Dimas costs between $149 and $299 for a standard sweep at a typical two-story foothill home, and we include a camera-scan inspection with every visit. Most San Dimas chimneys we open up were built in the 1960s through 1980s housing boom alongside the 210 corridor, which means clay tile liners that have absorbed forty to sixty winters of genuine cold-weather use. Call (980) 580-8641 and we’ll give you a written price before anyone starts.
Why San Dimas Homes Are Different
San Dimas sits directly at the base of the San Gabriel Mountains inside a state-designated Very High Fire Hazard Severity Zone, which changes what a chimney cleaning actually means here. The homes above Puddingstone Reservoir, along San Dimas Canyon Road, and up into the hillside neighborhoods behind the reservoir are surrounded by dry chamise and scrub oak that LA County Fire treats as ignition fuel. A single ember from a dirty flue landing in that brush is a documented wildfire pathway. In flat Pomona a mile south, a missing spark arrestor is a code note. In San Dimas, it’s the difference between a routine inspection and a structure defense call during Santa Ana season.
SCAQMD Rule 445 adds another layer. On No-Burn days throughout the winter, wood burning is restricted across the South Coast Air Basin. What we see in practice is that San Dimas homeowners burn intensely during the limited permitted windows rather than gradually across the season. That concentrates creosote deposition into fewer, heavier-use sessions, which means a flue that looked clean in October can be lined with flammable glaze by February.
The housing stock compounds it. San Dimas developed heavily between 1960 and 1985, and builders treated wood-burning fireplaces as a premium foothill amenity. The masonry fireboxes and clay tile liners in these ranch-style and split-level homes are now middle-aged at best. Mortar joints deteriorate, tile cracks open, and the cold snaps we get at 1,000 to 1,200 feet elevation mean real freeze-thaw cycling that widens those cracks every winter. A standard sweep has to catch all of that, not just the soot.
Our Main San Dimas Services
Beyond cleaning, San Dimas homeowners call us most often about two things: fireplaces that no longer draw or heat properly, and caps and crowns that have failed from years of Santa Ana wind and foothill sun.
Fireplace Services in San Dimas
Original masonry fireboxes in San Dimas ranch homes can develop cracked refractory panels, failing dampers, and smoke chambers that trap creosote behind decades of use. We rebuild these with current materials and angle the work around one local reality: these fireplaces are not ornamental here. They get lit on cold November nights when the temperature drops into the low 30s, and they need to pull correctly and hold heat. Fireplace Services in San Dimas covers full diagnostics, gas log conversion, and masonry firebox repair with a written scope before work begins.
Chimney Cap & Crown in San Dimas
Santa Ana winds funnel hard through the foothill gaps around San Dimas Canyon, and we regularly find caps that are corroded, undersized, or missing entirely. In a VHFHSZ, that is not a cosmetic issue. A proper cap with a functioning spark arrestor keeps embers inside the flue and keeps rain out of a clay tile liner that is already cracking. Chimney Cap & Crown in San Dimas covers stainless steel and copper cap replacement, custom crowns, and the spark-arrestor mesh sizing that local fire codes actually enforce here.

BeforeAfterChimney Cleaning & Sweep in San Dimas
Chimney cleaning in San Dimas means removing creosote and soot from a clay tile flue that has been through decades of real foothill winters, and doing it under conditions that demand more scrutiny than a sweep in the flatter valley cities. The No-Burn day schedule concentrates wood burning into short, intense windows, which produces the kind of glazed creosote that a basic brush-and-vacuum sweep will not fully remove. We run a Level 2 camera scan on every visit to document what the flue looked like before and after, because in this fire hazard zone the record matters as much as the cleaning itself. Our full service line is described at Chimney Cleaning & Sweep.
Level 2 Inspection
Signs you need it
You bought your San Dimas home in the last five years and have never seen the inside of the flue, or you had a chimney fire scare and need documented proof of condition for your insurer.
What it costs in San Dimas
A Level 2 inspection in San Dimas runs $249 to $449, and we include the full camera scan with photo record and written findings.
How we do it
We run a camera from the firebox to the flue cap, measure the liner, document every crack and gap, and hand you a written report with photos before you make any repair decision.
Creosote Removal
Signs you need it
Your fires burn smoky or you can scrape a black, shiny glaze off the damper frame with a butter knife, which is Class III creosote and a serious fire risk in San Dimas brush zones.
What it costs in San Dimas
Creosote removal in San Dimas runs $199 to $349 for a standard removal, and glazed Class III buildup can push it to $399 or more.
How we do it
We use rotary steel whip heads and a HEPA vacuum to break glazed creosote off the tile walls, then camera-scan the flue to confirm the surface is actually clean.
What Chimney Cleaning & Sweep Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Standard chimney sweep | $149 - $299 |
| Creosote removal (heavy or glazed) | $199 - $399+ |
| Level 2 camera inspection | $249 - $449 |
How often should my chimney be swept in San Dimas?
The National Fire Protection Association recommends an annual sweep, but San Dimas homes that burn wood every permitted day from November to March should be checked twice per season. Heavy glazed creosote can build in as few as ten intense burns.
Does a standard sweep include the spark arrestor check?
Yes. Because San Dimas hillside neighborhoods sit inside a VHFHSZ, every sweep includes a visual check of the cap and spark arrestor. We flag missing, undersized, or corroded arrestors in the written report.
Chimney Repair in San Dimas
Chimney repair in San Dimas usually starts with the same thing: a clay tile liner in a 40 to 60 year old ranch home has cracked open, and moisture or heat has been working through the mortar joints every winter since. The freeze-thaw cycle at this elevation widens hairline cracks into structural gaps faster than in warmer valley cities. Before any repair quote, we camera-scan the flue and show you exactly what we are fixing. You can see the full repair scope at Chimney Repair.
Mortar Repointing
Signs you need it
You can see crumbling mortar joints in the firebox or on the exterior chimney stack, or you find sandy grit in the firebox after a windy day.
What it costs in San Dimas
Mortar repointing in San Dimas runs $1,200 to $2,800 for a typical ranch home chimney stack, depending on access and how many joints need work.
How we do it
We grind out failed mortar, match the original joint profile, and repoint with a mix rated for repeated freeze-thaw cycling.
Flashing Repair
Signs you need it
You see water staining on the ceiling near the chimney chase after rain, or the metal flashing around the roof penetration is lifted, rusted, or patched with caulk.
What it costs in San Dimas
Flashing repair in San Dimas runs $450 to $950 for standard two-story homes, more when a roof in the hillside neighborhoods requires steep-pitch access.
How we do it
We cut back the old flashing, install new step and counter flashing, and seal the junction with a high-temp sealant rated for Santa Ana wind-driven rain.
What Chimney Repair Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Mortar repointing | $1,200 - $2,800 |
| Spalling brick repair | $800 - $2,200 |
| Chimney waterproofing | $350 - $650 |
| Flashing repair | $450 - $950 |
Can you repair my chimney without a full rebuild?
Yes, in most San Dimas homes we see repairable mortar and flashing failures long before a rebuild is necessary. The camera scan tells us the difference, and we will not recommend a rebuild on a flue that repointing will fix.
Do I need a permit for chimney repair in San Dimas?
For structural repairs like a full rebuild, yes. We handle the permit paperwork and coordinate with LA County. For repointing, flashing, and waterproofing, no permit is required.
Chimney Liner & Rebuild in San Dimas
Chimney liner and rebuild work in San Dimas happens when the original clay tile liner from a 1960s or 1970s build has cracked beyond repair and the flue is no longer safe or code-compliant. In a VHFHSZ, a compromised liner is more than a draft problem; it is a fire-containment failure waiting for the next Santa Ana wind event to test it. We quote liner and rebuild work with a camera-scan report in hand, and we source materials like DuraFlex and HeatShield stainless steel through our network to keep the price honest. The full liner scope lives at Chimney Liner & Rebuild.
Stainless Steel Liner
Signs you need it
Your camera scan shows cracked clay tiles, missing mortar joints, or gaps that let heat reach the chimney chase, and you want a liner rated for decades of foothill winters.
What it costs in San Dimas
A stainless steel liner installation in San Dimas runs $4,500 to $8,500 for a typical two-story home, depending on flue length and access.
How we do it
We size the liner to the appliance and flue, install it with proper insulation, and reconnect the firebox with a written warranty on the full system.
Partial Rebuild
Signs you need it
Your cap and top two feet of chimney are spalling or leaning, but the firebox and lower flue are structurally sound, which is common in San Dimas homes exposed to decades of wind-driven rain.
What it costs in San Dimas
A partial chimney rebuild in San Dimas runs $2,500 to $5,000, covering the top section from the roof line up.
How we do it
We tear down to sound structure, rebuild with new brick matched to the original, pour a new crown, and install a proper cap with spark arrestor.
What Chimney Liner & Rebuild Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Stainless steel liner | $4,500 - $8,500 |
| Flexible liner | $3,000 - $5,500 |
| Partial rebuild | $2,500 - $5,000 |
| Full chimney rebuild | $12,000 - $25,000+ |
Will a new liner fix my draft problem?
Often yes. A liner that is properly sized for your firebox or insert restores the draft the original clay tile lost as it cracked and narrowed. We verify with a smoke test after installation.
Does insurance cover liner replacement in San Dimas?
It depends on the cause. If a chimney fire damaged the liner, many policies will cover replacement. If cracking is from age, it is usually maintenance. We give you the camera documentation either way.

FAQs About Chimney Cleaning in San Dimas
Yes, and earlier than you think. San Dimas homeowners book heavily in September and October before the first cold snap, and the No-Burn day restrictions create a compressed window of heavy use. Call us in late summer and you’ll have your pick of dates.
Yes. Every visit includes a camera-scan photo record and a written report describing what we found, what we did, and what we recommend. That documentation is standard under Haven Standard Clause 4, not an add-on, and it’s acceptable for insurance and HOA files in San Dimas.
