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 Inspection Across Hercules
A chimney inspection in Hercules typically costs $189 – $389 depending on the level, and most appointments are booked within 3 – 5 business days. If you own a home in Hercules, especially in the older bayside neighborhoods built during the refinery boom, you need an inspector who understands what those chimneys actually look like inside. Flint Chimney Sweep has served Hercules homeowners long enough to know the postwar housing stock here often hides surprises behind the brick. Call (830) 251-4560 and we’ll give you a written price before any work begins.
Why Flint Chimney Sweep Is Hercules’s Preferred Chimney Inspection Company
Hercules homeowners call us because we document everything. When our technician finishes a Chimney Inspection, you get a photo report showing exactly what the camera saw inside your flue, not a verbal summary you have to trust. That matters in a city where many homes run two flues through one chase and a missed second liner can mean a missed fire hazard.
We’re part of the Garrison Partners family, founded in 2002, and every inspection runs under The Garrison Standard: a written price before the job, a background-checked and uniformed technician at your door, and a straight answer about what needs work now versus what can wait. Hank Delano oversees our Hercules dispatches personally, and he holds the same line on every job: if it’s not documented, it’s not done.
Response time to Hercules neighborhoods like Foxboro, the Waterfront district, and the hills off Refugio Valley Road is typically 3 – 5 business days. The phone is answered by a live person around the clock, so you’re never leaving a voicemail and hoping someone calls back.
Level 2 Chimney Inspection in Hercules
A Level 2 Chimney Inspection in Hercules is the inspection we recommend for most homeowners here, and it runs $289 – $389 for a single flue. This is a full camera inspection that runs from the firebox all the way to the chimney crown, documenting the condition of the flue liner, mortar joints, damper, and crown with still photos and video. In Hercules specifically, it’s the only way to catch what we routinely find in the 1940s and 1950s bayside flats: two flue liners sharing one chimney chase where the homeowner believed there was only one.
When a camera is non-negotiable
If you’re buying or selling a home in Hercules, a Level 2 inspection is the standard required by most local real estate contracts. If you’ve had a chimney fire, a seismic event, or any change to the fireplace or furnace venting, you also need one. The camera either confirms the flue is sound or it doesn’t, and you get the photos to prove it.
Two flues, one chase
This is the pattern that shows up again and again in Hercules: an original masonry fireplace from the 1940s or 1950s, plus a later addition whose furnace or fireplace flue was run up the same masonry chase. A standard Level 1 look-up inspection can miss the second liner entirely. Our camera goes up both flues, every time.
Chimney Leak in Hercules
A chimney leak in Hercules most often traces back to the chimney crown or the flashing where the chimney meets the roofline, and a standard leak diagnosis with camera inspection runs $289 – $389. Hercules gets its share of bay-driven winter rain, and water that pools around a cracked crown will work its way into the masonry and eventually into the living space. The smell is usually the first sign: musty, damp odor in the room near the fireplace, especially when the furnace cycles on.
What the photo report shows
Our technicians inspect the crown, the flashing, and the brickwork from the roof, then run the camera through the flue to look for water staining, spalling mortar, and rusted components. Every finding gets photographed and included in your report. A cracked crown or failed flashing can frequently wait until spring. A blocked flue or a damaged liner cannot.
Wait or act now
This is where we earn our keep in Hercules. Some chimney companies will tell you every leak needs immediate work. We won’t. If the flue is sound and the leak is limited to a crown crack that can be sealed when the weather turns, we’ll tell you that in writing and give you a price for the repair so you can plan it. If the liner is spalling or the damper isn’t sealing, we’ll tell you that plainly too, with photos.
Trusted Brands We Service in Hercules
Flint Chimney Sweep works with professional-grade chimney materials specified by the job, not by margin. When a Hercules home needs a resurfaced liner, we use HeatShield. When it needs a new stainless liner, we install DuraFlex or Olympia Chimney products. Replacement dampers and chimney caps come from Famco and Copperfield. We keep common components in local Bay Area stock, which means a Hercules repair doesn’t wait a week for parts to ship across the country. You get a written price for the exact product going in, so there’s no guesswork about what you’re paying for.
Common Chimney Inspection Problems We See in Hercules Homes
- Two flues in one chase. The original 1940s – 50s masonry fireplace shares its chimney with a later addition’s furnace flue. A Level 1 inspection often catches only the first flue and misses the second entirely.
- Spalling mortar in original clay liners. Sixty-plus years of Bay Area temperature swings and moisture cycles break down the mortar between clay tiles. The camera shows it as flaking, crumbling joints that can let heat and carbon monoxide escape the flue.
- First-degree creosote misdiagnosed as third-degree. Without a proper visual or camera assessment, some companies push a full aggressive brush when a chemical treatment is all the flue actually needs. We treat first-degree creosote as first-degree creosote.
- Cracked crowns and failed flashing from winter rain. Hercules gets enough wet weather off the Bay that crowns crack and flashing pulls away. These are visible on a photo report, and they can typically wait for a dry-weather repair, unlike a blocked flue or open damper.
Pricing for Chimney Inspection in Hercules, CA
A Level 1 inspection in Hercules runs $189 – $249. A Level 2 inspection with full camera documentation runs $289 – $389 for a single flue. Homes with the two-flues-in-one-chase setup run toward the upper end of that range because both liners get inspected. A Level 3 inspection, which involves removing part of the chimney structure to access a hidden problem, is quoted on a per-case basis after the Level 2 camera work tells us what’s actually going on. Every quote is written before any work starts. Call (830) 251-4560 for a free estimate, and we’ll give you an exact number for your Hercules home.

FAQs About Chimney Inspection in Hercules
No. If you burn fewer than a dozen fires a year and the fireplace drafts well, a Level 1 inspection every two to three years is usually sufficient. What you do need is a camera-based Level 2 inspection when you buy or sell the home, after any chimney fire or earthquake, or if you notice a new smell or drafting problem. We’ll tell you plainly if a more frequent schedule is needed, and we’ll never sell you an inspection you don’t need. Call (830) 251-4560 to talk it through.
A Level 1 inspection is a visual check of the accessible parts of the chimney and flue; it’s appropriate for an annual checkup on a chimney that hasn’t changed. A Level 2 is the same plus a full camera scan of the entire flue interior, the smoke chamber, and the exterior crown and flashing. Most Hercules homes should get a Level 2 the first time we inspect them, because the two-flue-in-one-chase pattern means the extra camera coverage actually changes what we find. After that first comprehensive look, Level 1 is often all you need.
Chimney cleaning is needed when creosote buildup reaches a depth that actually poses a fire risk, not on a fixed calendar. In Hercules, a fireplace used two or three nights a week during the cooler months typically needs sweeping once a year. A fireplace used once a month can usually go two years. The only way to know is to look at the flue, and our camera shows you the buildup with photos. If the buildup is first-degree, a chemical treatment can often handle it and the brush can wait another year. We’ll tell you which applies to your chimney, and the recommendation goes in writing.
You’ll get photos. Every Level 2 inspection includes a photo report documenting the flue liner, mortar joints, damper, crown, and any defects we find. In Hercules, where we routinely find things like two flues in one chase or spalling mortar in a 1950s liner, the photos are what let you verify the problem yourself. Nothing gets recommended without camera evidence you can see.
We don’t promise same-day service; our Hercules appointments are typically booked 3 – 5 business days out. But if you smell smoke when the fireplace isn’t in use or you’re getting a draft back into the room, that’s a call worth making today. The phone is answered by a live person around the clock, and we’ll get you on the schedule as soon as the calendar allows. For a blocked flue or a suspected chimney fire, call (830) 251-4560 and we’ll tell you what to do right then.
