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.

AfterFast, Reliable Chimney Sweep Across Martinez
A standard chimney sweep in Martinez runs $180 – $260 and typically takes 60 – 90 minutes including setup, the sweep itself, and the final photo report. The number that matters more than the base price is whether the technician actually looks at what the brush missed, and on older Martinez brick chimneys, that means a camera. Call us at (830) 251-4560 and we’ll put the flat price in writing before we schedule the truck.
We work throughout Martinez, from the early-1900s homes along Alhambra Avenue and downtown to the larger lots up in Alhambra Valley and across the hills toward Hidden Lakes. If you call from a house near John Muir National Historic Site or off Center Avenue, one of our crews is already working a route through Contra Costa County most weeks. We know what these chimneys look like inside, and we’ll show you the photos to prove what we found.
Why Flint Chimney Sweep Is Martinez’s Preferred Chimney Sweep Company
We’ve cleaned chimneys in Martinez since 2002, first as part of the Garrison Partners family of chimney service companies and now as Flint Chimney Sweep, operating under the same Garrison Standard that every independently owned location follows. That standard is simple: a written price before any work starts, a background-checked and uniformed technician on every call, and a written guarantee on every repair that’s valid for a full year. No exceptions.
Hank Delano leads our crews, and the rule he’s enforced from day one is that no Martinez homeowner gets a recommendation they can’t verify. That’s why every sweep includes a camera inspection and a photo report. If we flag a crack in the flue, you see the crack. If the crown is spalling, you see daylight through it in the photos. Not a sales pitch. Evidence.
When you call, a live person answers. Not a voicemail tree, not a callback form. That’s true at 9 a.m. on a Tuesday and at 2 a.m. on a Sunday. And when we give you a window for arrival, we work inside it, because dispatch in the San Francisco Bay Area office coordinates routes so Martinez appointments don’t get stacked behind three other cities.
Chimney Maintenance in Martinez
Chimney Maintenance in Martinez means more than running a brush up the flue once a year. On the older brick homes here, particularly those built before 1940 with original masonry and no clay flue liner, maintenance is what keeps a small mortar crack from becoming a $3,000 reline job. A Chimney Maintenance visit in Martinez runs $180 – $260 and includes the sweep, the Level 1 inspection, and a written photo report of everything we saw.
The marine-influenced climate here cycles from winter rain to summer fog to gusty east-wind days, and that cycle is hard on exterior masonry. Moisture gets into the crown, the sun dries it out, and the cycle repeats until the crown spalls. Catching that early is a $400 crown repair. Missing it is a $2,500 – $3,800 water-damage chimney restoration. We’d rather you spend the smaller number.
Seasonal Readiness Sweep
Most Martinez homeowners burn from late October through March, which means the window for a pre-season sweep is September and early October. A Seasonal Readiness Sweep clears the soot and creosote built up from the prior winter, checks the damper for smooth operation, and confirms the flashing is still sealed where the chimney meets the roofline. It’s the same flat $180 – $260 price, and you get the photo report same day.
Post-Storm Chimney Check
After a wet winter in Martinez, water makes itself known in chimneys. A Post-Storm Chimney Check includes the camera inspection to look for moisture intrusion into the flue, a close look at the crown and chimney cap, and a written recommendation on what can wait and what can’t. If everything is sound, you pay only the inspection fee and we tell you plainly that nothing needs doing. That’s a normal outcome, not a rare one.
Chimney Sweep Services in Martinez
Chimney Sweep Services in Martinez start with the same promise every time: the flat price is agreed before booking, the technician arrives in uniform, and you get a camera inspection with a photo report whether the house is a 1920s bungalow off Alhambra Avenue or a newer build in Hidden Lakes. A standard sweep in Martinez runs $180 – $260. It includes brush work through the flue, soot removal from the firebox, and the Level 1 inspection.
The brush does the obvious work. It’s the camera that does the honest work. On Martinez’s original brick chimneys, first-degree creosote hides in mortar joints where a brush can’t reach, and the only way to document that is with a camera run through the smoke chamber to the crown. If the photos show a problem, we show you the photos and give you a written quote on the spot. If they show a clean flue, we tell you that too.
Creosote Removal and Fireplace Cleaning
Creosote Removal is the focused version of the sweep, for chimneys where the camera shows first- or second-degree buildup and the homeowner wants the flue addressed before it glazes. On an older Martinez chimney without a modern clay liner, we treat this as a longer appointment: the brush comes out first, then the camera goes back up to confirm the mortar joints are clear. Fireplace Cleaning covers the firebox itself, the damper assembly, and the hearth, usually included with the standard sweep price.
Annual Sweep and Fireplace Cleaning
An Annual Sweep in Martinez is the smart default for anyone who burns a cord or more a year, even if the fire is more for ambience than heat. Wood from eucalyptus and almond, both common around the Alhambra Valley and up toward Franklin Ridge, burns dirtier than oak or almond from farther inland. The creosote from those woods tends to build faster and stick harder. Booking the Annual Sweep keeps the flue at a level where a brush still works, instead of a level where only chemical treatment or brushing plate removal does.

Trusted Brands We Service in Martinez
When a Martinez chimney needs parts, we don’t use whatever is on the truck. We specify by job. That means Famco caps and dampers when the existing hardware has rusted through, Copperfield crowns and flashings when the exterior masonry has failed, and DuraFlex or HeatShield liners when an older Martinez brick chimney needs a reline or a patch on second-degree creosote damage near the smoke chamber. We quote these by name, so you can look up exactly what you’re buying before you approve it. Most common parts are stocked on the truck or available for a follow-up visit without a special order.
Common Chimney Sweep Problems We See in Martinez Homes
- Original brick chimneys with no clay flue liner. This is the biggest one in Martinez, especially downtown and in the older Alhambra Valley homes built before 1940. A standard brush leaves first-degree creosote in the mortar joints, and by the time it glazes to third-degree, the brush won’t touch it.
- Stuck dampers from coastal air and disuse. The damp fog off the Carquinez Strait keeps metal dampers damp, and when a damper stays shut through two winters of disuse, the lever assembly rusts. We regularly free dampers on the first sweep, but occasionally the frame itself has degraded and needs replacement.
- Spalled crowns from the winter rain and summer heat cycle. Martinez’s microclimate swings from wet to dry to windy, and the crown at the top of the chimney takes all of it. A spalled crown lets water into the masonry, which then freezes and fractures the brick. We see this more often than glazed creosote, and it’s far more expensive when ignored.
- Third-degree creosote from eucalyptus and almond wood. Both woods are common firewood around Martinez, and both produce dense smoke that cools quickly in unlined brick flues and forms glazed creosote. By the time it’s third-degree, only mechanical removal or a HeatShield treatment will address it. Burning a few cords a year doesn’t exempt you. It just changes the timeline.
Pricing for Chimney Sweep in Martinez, CA
A standard chimney sweep in Martinez runs $180 – $260, and that’s a flat price agreed before we book the appointment. The camera inspection and photo report are included in that price, not an add-on. A Level 2 inspection (full camera work, attic and crawl space access, exterior chimney evaluation) runs $300 – $450, which is the right call after an earthquake, before buying a home here, or when you see visible smoke stains on the interior wall near the chimney. Repairs are priced as separate written quotes, and you approve the number before any work starts. If a covered repair fails within 365 days, we return at no charge. Call (830) 251-4560 for a free estimate on any of it.

FAQs About Chimney Sweep in Martinez
Once a year, and the reason is eucalyptus and almond wood, not the cord count. Both woods burn hot at the start and cool quickly in an unlined brick flue, which is exactly the condition that forms first-degree creosote in mortar joints. A camera inspection catches it. A brush alone misses it. Call (830) 251-4560 and we’ll give you a straight answer on whether your chimney can safely wait.
No. The camera inspection and photo report are included in the $180 – $260 sweep price, every time, regardless of the age of the chimney. On older Martinez brick chimneys without clay flue liners, the camera is the only way to see whether first-degree creosote is building in the mortar joints, so we don’t offer a sweep without it. If the photos show a problem, you see the exact image we saw, and you get a written quote. If they don’t, you get the photos and an honest “nothing needs doing.”
First-degree creosote is a fine black soot that brushes off easily. Second-degree is flaky and granular, like coffee grounds, and it needs mechanical brushing to remove. Third-degree is glazed and tar-like, and a brush won’t touch it; it requires chemical treatment or a specialist product like HeatShield. On Martinez’s original brick chimneys without modern clay liners, first-degree creosote hides in the mortar joints where a brush can’t reach, so it advances to second- and third-degree faster than on a lined flue. The camera inspection tells you which degree you’re dealing with before you decide what to do.
A blocked flue is a carbon monoxide risk, and that’s not a seasonal thing. If the camera inspection shows third-degree creosote narrowing the flue, or a damper stuck shut, or a collapsed clay tile, fix it before you burn again, regardless of the calendar. But if the chimney is clean and the only issue is a spalled crown that will worsen over winter, that can often wait until spring. We’ll tell you which one you have, with photos, and we won’t push a repair you don’t need. Call (830) 251-4560 to schedule the inspection that answers the question.
We stock and install Famco caps and dampers, Copperfield crowns and flashings, and DuraFlex and HeatShield liners and patch systems. Part selection is by job, not by margin, so the written quote names the exact product and the reason it’s specified. On older Martinez homes, a HeatShield patch often solves a localized second-degree creosote patch without a full reline, which saves thousands. If a covered repair fails within 365 days, we return at no charge. Call (830) 251-4560 to get the quote in writing.
