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.

Why Flint Chimney Sweep Is San Martin’s Preferred Chimney Sweep Company
San Martin homeowners call us for a specific reason: they want the price in writing before the work starts, and they want proof of what’s actually inside the flue. We’ve built our reputation in this valley on those two commitments. When a technician pulls up to a home off Highland Avenue or San Martin Avenue, the homeowner already knows the exact scope, the exact price, and who’s walking through the door.
Our crews know the housing stock here. Ranches from the 1960s and 1970s, newer builds east of 101, and a handful of older farmhouse-style properties each have different flue liner conditions and damper configurations. We don’t treat them the same. A chimney sweep in San Martin should account for the damp air that sits over the valley floor most mornings and evenings, and the spalling mortar it accelerates on chimney crowns.
Hank Delano, who runs Flint Chimney Sweep, sets the standard every technician follows: put the price down first, do the work clean, and stand behind it for a full year. That’s not marketing language. It’s the Garrison Standard, and it applies to every San Martin job we book.
Chimney Sweep Certified in San Martin
Chimney Sweep Certified in San Martin means the flue gets rodded from top to bottom, the smoke chamber gets hand-scraped, the damper gets checked for free movement, and the firebox gets cleared of ash and debris. A Level 1 inspection is part of the job, not an add-on. Every San Martin homeowner gets a camera report with still photos showing the before and after, so you can see what was removed and what condition the liner is in. A typical sweep runs $189 – $259, and the price is written down before we book the appointment.
Creosote and Soot Removal
Creosote is the sticky, tar-like residue that condenses on flue walls when smoke cools too quickly. In San Martin, where cold air pools on the valley floor and marine fog pushes over the hills, flues stay cooler and damp longer, so creosote builds up faster here than in drier inland towns. We remove first-degree (flaky), second-degree (glazed and tacky), and third-degree (hard, shiny, and fuel-rich) creosote using mechanical rods and hand scrapers, not chemical sprays that mask the problem.
Annual Sweep and Fireplace Cleaning
If you burn more than one cord of wood per year, book an annual sweep. San Martin homes with older, open-hearth fireplaces tend to burn shorter, smoldering fires on damp winter nights, and those low-temperature burns produce more second-degree creosote, not less. We’ll schedule you a year out and call to confirm the week before, so you don’t have to remember on your own.
Gas Fireplace Cleaning in San Martin
Gas Fireplace Cleaning in San Martin involves removing the glass, vacuuming the firebox, cleaning the burner ports, checking the pilot assembly, and testing the log placement for soot patterns that indicate incomplete combustion. Gas fireplaces still accumulate dust, pet hair, and fine soot, and the damper or venting still needs to be checked for blockage. The service runs $149 – $219 for most units, with a written price before booking. If you’ve noticed the flames burning yellow or orange instead of blue, or the glass has a cloudy film that won’t wipe off, it’s time to have it serviced.
Log Set and Burner Inspection
Ceramic log sets crack over time, and when they do, the flame pattern changes and soot builds unevenly. We inspect the logs for fissures, clean the burner ports with a soft brush and compressed air, and verify the thermocouple and thermopile are generating correct millivolts. This is the difference between a fireplace that lights reliably and one that shuts itself off on a cold night.
Glass and Venting Check
Soot fog on the inside of the glass usually means the air-to-fuel mixture is off. We clean the glass with ceramic-safe cleaner, adjust the air shutter if needed, and check the vent termination outside for debris or nesting material. Around San Martin, where valley oaks and eucalyptus grow tall, vent caps get clogged more often than people realize.
Trusted Brands We Service in San Martin
We install and work with professional-grade chimney components from Famco, Copperfield, HeatShield, and DuraFlex. That matters because the part you can’t see is the one that has to hold up for years. A Famco cap, a Copperfield damper, a HeatShield liner repair, or a DuraFlex stainless liner each gets specified by job, not by margin. We keep common caps and dampers stocked for faster turnaround on San Martin jobs, so you’re not waiting on a backorder while the fog season arrives.
Common Chimney Sweep Problems We See in San Martin Homes
- Damp-cycle spalling on crowns and mortar joints. San Martin’s cold-air pooling and marine fog keep masonry damp for hundreds of hours each year. Freeze-thaw cycles may be rare, but constant moisture weakens mortar, and we regularly see flaking crowns on 1970s ranches near Llagas Road.
- Second-degree creosote glazing in the smoke chamber. Short, smoldering burns on damp nights produce tacky creosote that coats the smoke chamber walls. It’s a fuel load that a simple flue brush never touches, and it’s the leading cause of chimney fires we see in the 95046 area.
- Skipped dampers. Some companies brush the flue and call it done. We check the damper on every San Martin sweep, because a stuck or warped damper changes burn characteristics and lets warm air escape all winter.
- Missing or damaged rain caps. Without a proper cap, rain falls straight down the flue and soaks into the firebox. Add San Martin’s damp air on top of that, and you get rusted dampers and crumbling firebrick faster than you’d expect.

FAQs About Chimney Sweep in San Martin
If you burn more than one cord of wood per year, sweep it annually. If you burn occasionally, every two to three years is usually enough, but San Martin’s damp air can make creosote accumulate faster even with light use, so a camera check every two years is the safest path. Call (830) 251-4560 and we’ll give you a straight answer for your specific fireplace.
No, and here’s why: a proper sweep includes a camera inspection, hand-scraping, and a written photo report. That kind of work is scheduled, so we can arrive with the right tools and enough time to do it correctly. We’ll book you for the earliest available window, and we’ll call if anything changes. Call (830) 251-4560 to see what we have open this week.
First-degree creosote is flaky and brushes off easily. Second-degree is glazed and tacky, and it’s the one we see most in San Martin because damp, cool flues freeze creosote mid-condensation into a sticky layer that resists brushing. Third-degree is hard, shiny, and highly fuel-rich, and it requires chemical treatment or mechanical removal before you burn again. All three are visible in our camera report, so you’ll know exactly what we found. Call (830) 251-4560 to book a sweep and see for yourself.
Sometimes, yes. If the camera shows a clean flue, an intact liner, and a functioning damper, we’ll tell you plainly that you’re clear to burn. What shouldn’t wait is a cracked liner, a spalling crown, or a missing rain cap in San Martin, because the damp air here accelerates water damage once moisture gets in. We’ll show you the stills and give you a written repair quote; you decide when to schedule it. Call (830) 251-4560 for a free estimate.
A camera inspection and photo report includes a full video scan of the flue interior, still photos of problem areas, documentation of creosote degree and thickness, and a written summary of the liner condition, smoke chamber, and damper. You get the report before we leave the property, and it’s yours to keep. That’s what a proper chimney sweep in San Martin should deliver. Call (830) 251-4560 to book yours.
