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 Alcott Chimney Sweep Is Kentfield’s Preferred Chimney Inspection Company
Homeowners in Kentfield call us because we show our work. Every inspection comes with camera documentation, a written price before anything is recommended, and a written guarantee on any repair. No exceptions. Ruben Castellano runs Alcott Chimney Sweep, and the standard we hold here is straightforward: you know exactly who is coming to your door before they knock. Every technician passes a background check and identity verification under the Threshold Standard, and we send you the technician’s name and photo before the visit. They arrive in uniform and show a photo ID badge at the door.
We’ve been serving homeowners since 2002 as part of the Threshold Group family. That matters in a place like Kentfield, where the housing stock is older, the moisture load is higher, and the inspection interval has to account for local conditions instead of a generic one-size-fits-all calendar. Our Chimney Inspection team has pulled cameras through enough Kentfield flues to know what fails first here: galvanized caps, mortar-washed flues, spalling crowns, and flashing that lifts once the counter-flashing loses its seal.
You’ll get a real person on the phone, every time. If something smells like smoke at 11 p.m., you aren’t routed to a voicemail box. You get an answer.
Chimney Inspection Services in Kentfield
Chimney Inspection Services in Kentfield mean more than a quick glance up the flue. In this valley, a proper inspection has to account for what the local climate does to masonry and metal. We check the flue, the crown, the cap, the flashing, the firebox, and the smoke chamber, then document everything on camera so you can see exactly what we saw. A Level 1 inspection in Kentfield runs $189 to $279 and is the right call for homes that use the fireplace routinely and haven’t had a change in venting or performance. A Level 2 inspection, which we recommend when there’s been a moisture intrusion, a chimney fire, a real estate transaction, or a change in the flue configuration, typically runs $349 to $549 in Kentfield and includes full camera documentation of the interior flue surfaces.
Level 1 and Level 2 Inspections
Most routine checks we perform in Kentfield are Level 1 inspections, which examine the readily accessible portions of the chimney, flue, and appliance connections. If you’ve had a chimney fire, you need the Level 2. If you’re buying or selling a Kentfield home, the buyer’s lender or insurer will often require a Level 2 before closing. And if you’ve just discovered that your cap has rusted through, a Level 2 is the only way to see what the moisture did downstream before you spend money on a fix.

Camera Inspection and Flue Documentation
Camera inspection is included in every Level 2 we do in Kentfield, and we’ll show you the footage on the spot. What we find in Kentfield flues often surprises homeowners, especially the mid-century brick chimneys with no clay-tile liner. The camera work is what lets us say plainly whether a liner is needed or whether a cleaning is enough. We won’t quote a liner without camera evidence you’ve seen yourself.

Chimney Flue Inspection in Kentfield
Chimney Flue Inspection in Kentfield homes is where we find most of the real problems. The flue is the vertical passage that carries smoke and gases out of your house, and in Kentfield, it often sits wet for months at a time. A standard flue inspection here includes checking for cracks, gaps, deterioration in the clay-tile liner if one exists, and creosote buildup, which is the tar-like substance that causes chimney fires. Flue inspection in Kentfield runs $189 to $549 depending on level, and in this climate, it’s the single most important piece of any chimney service call.
Unlined Mid-Century Flues
Kentfield’s housing stock leans heavily on 1930s through 1960s construction, and many of those original brick chimneys were built without proper clay-tile flue liners, or with liners that have since cracked and aged past usefulness. We find unlined, mortar-washed flues in this community on about half of the older homes we inspect. A flue in that condition lets heat and gases contact the masonry directly, and when moisture is already working the joints from outside, the risk compounds.
Moisture-Driven Flue Damage
What we look for most often in Kentfield flues is moisture intrusion. Cracked crowns let rain in. Rusted caps let rain in. Lifted flashing lets rain run down the outside of the chimney and soak the masonry. Once water works into a flue, it freezes and thaws through our damp winter cycles, and that’s how hairline cracks become structural problems. None of this is visible from the ground, which is why the camera work matters.
Trusted Brands We Service in Kentfield
When a Kentfield flue needs more than a cleaning, we work with professional trade materials, not box-store substitutes. That means HeatShield resurfacing for deteriorated flue interiors, Gelco refractory products for firebox repairs, and Olympia Chimney and Famco components for caps and chase covers. We keep common parts in local stock for faster turnaround on Kentfield jobs, and everything we install carries the same written guarantee as the labor. The 365-Day Done Right Promise applies across the board: if the work isn’t right, we make it right, and if a repair fails within the coverage period, the second visit is free.
Common Chimney Inspection Problems We See in Kentfield Homes
- Rusted galvanized chimney caps. Kentfield’s wet-season humidity pits and rusts galvanized caps within a few seasons, and once the seams open up, bay laurel litter and direct rain pour into the flue. We recommend stainless multi-flue caps for homes here, because the galvanized ones simply don’t last in this microclimate.
- Unlined or mortar-washed mid-century flues. Original 1930s to 1960s brick and stone chimneys in Kentfield were frequently built without clay-tile liners. Mortar joints erode under sustained moisture, and spalling masonry can compromise the firebox before you ever see it from the outside.
- Moss and lichen on chimney crowns. The Ross Valley rainfall trap keeps crowns damp through the long rainy season, and moss roots into any crack it can find. Once a crown spalls, water tracks down into the flue, and the flashing below starts to lift.
- Bay laurel leaf mats above the damper. The hillside lots around Kentfield are blanketed in California bay laurel, and the oily leaves shed constantly. They accumulate above the damper into a dense mat that burns with a quick, hot flash rather than the slow smolder of creosote, which is why a homeowner who swears they only burn clean firewood can still be at risk.

FAQs About Chimney Inspection in Kentfield
Every year, and here’s why Kentfield can’t borrow a drier town’s interval. The Ross Valley rainfall trap keeps your chimney masonry wet for months, and the bay laurel canopy drops oily leaves into open flues all autumn. An annual Level 1 inspection catches crown cracks, rusted caps, and litter mats before they become structural problems. If you’ve had a chimney fire, a major storm, or a change in venting, move to a Level 2. For a same-week inspection in Kentfield, call (336) 863-3889.
A Level 2 inspection adds full video camera documentation of the flue’s interior, including the attic and crawl space portions you can’t see without equipment. In Kentfield, we recommend a Level 2 after any chimney fire, before a real estate closing, after moisture intrusion, or when the venting configuration has changed. If your galvanized cap has rusted through and let rain into the flue, that’s a Level 2 situation. Call (336) 863-3889 and we’ll tell you over the phone which level fits your home.
Often, yes. A substantial share of Kentfield’s 1930s-to-1960s brick and stone chimneys were built without clay-tile flue liners, or with liners that have cracked and deteriorated beyond safe use. We find mortar-washed flues frequently during inspections here, and that condition means heat and combustion gases contact the masonry directly. The fix is a HeatShield resurfacing or a stainless liner, and we’ll show you the camera footage before you spend a dollar on it. Call (336) 863-3889 for an inspection and a written quote.
Bay laurel leaves are dense with aromatic oils, and when they dry in a flue, they ignite with a fast, hot flash rather than the slow-burning smolder of wood creosote. In a hillside Kentfield home with the canopy directly overhead, a thick mat of these leaves can sit above the damper and flash at temperatures that stress the flue walls. It’s one of the reasons we recommend annual inspections here even for homeowners who never burn unseasoned wood. Call (336) 863-3889 and mention the bay laurel, and we’ll walk you through what we check.
The cap and the crown fail first. Kentfield’s damp season rusts galvanized caps at the seams within a few years, and moss-driven spalling opens crown cracks that let water into the flue and the smoke chamber. Once the cap and crown are compromised, the flashing lifts and moisture tracks down through the masonry. Putting it right means documenting the damage on camera, replacing the cap with stainless, sealing or rebuilding the crown, and often lining the flue with HeatShield or a stainless system. It’s a single moisture-corrective scope, not a patch-and-return cycle. Call (336) 863-3889 for a free estimate and we’ll show you exactly what your chimney needs.
If you live in Kentfield and want an inspection you can actually see and understand, call us at (336) 863-3889. We’ll send a tech whose name and photo you’ll know before the visit, quote you a written price before any work starts, and guarantee every repair in writing, backed by the 365-Day Done Right Promise.
