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 Walnut Creek’s Preferred Chimney Inspection Company
We’ve inspected hundreds of Walnut Creek chimneys since 2002, and the houses here have a pattern we know well: 1950s – 1970s ranch and split-level homes with original masonry fireplaces, many retrofitted with gas inserts in the 1990s. That retrofit story matters, and we’ll come back to it. What Walnut Creek homeowners tell us they value most is knowing exactly who’s coming to their door. Ruben Castellano runs Alcott Chimney Sweep with a rule that every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. When our tech rings your bell, they show a photo ID badge. No exceptions. Ever.
We answer our phones with a live person around the clock. If you smell smoke at 11 p.m. and need to know whether it’s an emergency or can wait until morning, you’ll talk to someone who can help, not a voicemail prompt. Walnut Creek is squarely in our service area, and our crews know the quickest routes across the 580/680 interchange neighborhoods, so we can usually reach a Northgate or Countrywood address within a day or two of your call.
Our Walnut Creek customers also get something most chimney companies don’t offer: a written price before any work begins, always, and a written guarantee on every repair. If a repair fails within 365 days, the second visit is free. That’s the 365-Day Done Right Promise, and it’s not an upsell. It’s just how we work.
Level 2 Chimney Inspection in Walnut Creek
A Level 2 Chimney Inspection in Walnut Creek is the inspection level we recommend for most homes here, and it’s what you need if you’ve just bought a house, if you’re relining or modifying your fireplace, or if you haven’t had the flue looked at in years. It includes everything a Level 1 covers plus a camera scan of the entire flue interior, from firebox to chimney cap. The camera is the workhorse here: it shows cracks in terra cotta tile liners that are invisible from the roof or the firebox, and it documents every finding in photos you can see for yourself.
In Walnut Creek specifically, we recommend a Level 2 inspection for any home built before 1980 that still has its original clay tile liner. The Diablo Valley’s temperature swings, 100°F+ summer days against cool, damp winter nights, stress those tiles until they crack. A cracked flue liner in an older Walnut Creek fireplace isn’t rare; it’s closer to the default, and the fix is usually a HeatShield resurfacing or a DuraFlex steel liner, not a full rebuild. Cost for a Level 2 inspection in Walnut Creek runs $349 – $549, and the camera report is yours to keep.
When a real estate transaction requires it
Walnut Creek has a steady flow of home sales in neighborhoods like Lakewood and Countrywood, and many purchase contracts now require a Level 2 inspection as a condition of closing. We perform these inspections for buyers, sellers, and agents on a quick timeline, and the written camera report holds up in negotiation. No vague “needs work” notes. You’ll see the condition of the flue, crown, and damper in photos.
What the camera shows that a quick look can’t
From the roof, a chimney can look fine. The camera tells a different story. It catches spalled chimney crowns, cracked clay tiles, missing mortar joints, and animal nests packed deep in the flue, things you’d never see with a flashlight. We don’t recommend any repair off a hunch. If we recommend a liner, you’ll see the crack on camera first.
Chimney Leak in Walnut Creek
A chimney leak in Walnut Creek homes is usually traced to one of three places: a failed chimney crown, worn or improperly installed flashing where the chimney meets the roofline, or a cracked flue liner letting moisture into the masonry. Walnut Creek’s winter rains, which can arrive in sudden heavy bursts, find these entry points fast. A small crown crack in September becomes a water stain on your ceiling by February if it goes unaddressed.
Diagnosing a chimney leak starts with a Level 2 camera inspection. We don’t guess. The camera shows exactly where the liner has failed, and a roof walk lets us check the crown and flashing with the same documentation. We use professional-grade materials for the repair itself: HeatShield resurfacing for flue liner restoration, Gelco crown sealant, and Olympia Chimney flashings where appropriate. These are brands chimney professionals specify, not box-store substitutes.
Crown repair without a full chimney rebuild
A deteriorating crown is the single most common chimney leak source we document in Walnut Creek. The good news is most crowns can be resealed with Gelco rather than completely rebuilt, a repair that typically runs $350 – $900 in Walnut Creek depending on crown size and condition. We document the deterioration with photos before and after.
Flashing failures on older Walnut Creek rooflines
The 1950s and 1960s split-levels and ranches in neighborhoods like Northgate have rooflines that meet chimneys at angles a modern roof crew doesn’t always flash correctly. We see improperly lapped flashing regularly. Reflashing a single chimney in Walnut Creek usually runs $500 – $1,200, and we spec Olympia Chimney flashing with the correct counterflashing detail so the repair lasts past the next rain season.
Trusted Brands We Service in Walnut Creek
We install and service the professional-grade materials Walnut Creek homes actually get spec’d by certified chimney technicians: HeatShield for flue resurfacing, Gelco for crown and brickwork sealing, and Olympia Chimney for component replacements. We keep these products in local inventory for Walnut Creek jobs, not ordered in from across the country, so a repair quote turns into a scheduled repair without a two-week parts delay. If your existing chimney has Famco components, we service those too. The point is we don’t improvise with materials that weren’t designed for high-heat flue conditions, and we can explain the difference in plain English if you ask.
Common Chimney Inspection Problems We See in Walnut Creek Homes
- The 1990s gas insert blind spot. Homeowners in Northgate, Lakewood, and Countrywood often assume a gas insert retired the chimney entirely, so the masonry chase, crown, and spark arrestor above the insert go unexamined for decades. The chimney above that insert still deteriorates and still needs an annual look.
- Spalled terra cotta liners. The original clay tile flues in 1950s – 1970s ranch and split-level homes crack from Diablo Valley temperature swings, and the cracks are completely invisible without a Level 2 camera scan. A cracked liner is an ember pathway and a carbon monoxide risk, not just a cosmetic flaw.
- Animal nesting after the long dry season. Walnut Creek’s dry summers make chimneys prime nesting habitat for birds and raccoons. A flue packed with nesting material meeting a fall Diablo wind event is exactly the ember pathway we work to close before burning season starts.
- Crown and flashing failures caught late. Sudden winter rain bursts expose small crown cracks and flashing gaps quickly. What starts as a $400 crown reseal becomes a $3,000 masonry repair if the water has had a full rainy season to work into the brick.
Pricing for Chimney Inspection in Walnut Creek, CA
A standard Level 1 inspection in Walnut Creek runs $189 – $249.

Level 3 inspections, which are rare and involve partial demolition to access concealed flue sections, are quoted case by case.

FAQs About Chimney Inspection in Walnut Creek
Because even a barely-used chimney is exposed to Diablo Valley weather extremes, animal nesting, and masonry shifts, and the parts that fail, crown, flashing, spark arrestor, don’t know how often you light a fire. Walnut Creek’s dry summers invite birds and raccoons into unused flues, and fall wind events can push embers from a neighbor’s fire into a chimney filled with nesting material. An annual inspection catches these before they become a fire event or a leak. Call (336) 863-3889 to book a Level 1 or Level 2 inspection; we’ll tell you which is right for your chimney.
No, and this is the single biggest misconception we run into on Walnut Creek service calls, especially in Northgate, Lakewood, and Countrywood. The gas insert removes the open firebox, but the masonry chase, chimney crown, spark arrestor, and damper above the insert all remain in service and keep deteriorating. Many of these chimneys haven’t been inspected since the insert went in 25+ years ago. We inspect above the insert with a Level 2 camera scan to document exactly what’s happening up there. Call (336) 863-3889 if your gas insert chimney hasn’t been looked at this decade.
A Level 2 inspection shows the entire flue interior on camera, from firebox to cap, including the areas you can’t see from the roof or the hearth: cracked terra cotta tiles, failed mortar joints, concealed animal nests, and liner deterioration. In Walnut Creek’s older homes, the cracks that put your house at risk are almost never visible without the camera. Everything is documented in photos you can review with the technician before any repair is quoted.
Because we show you the camera footage. We don’t recommend any repair, liner or otherwise, without photographic evidence you can see for yourself. If our tech says your flue needs a HeatShield liner, you’ll see the crack or deteriorated tile on screen, and the same photos are in your written report. We also give you a written price in advance and a written 365-day guarantee on any repair we do. If a repair fails within the year, the second visit is free. Call (336) 863-3889 and ask us to show you the documentation standard before you book.
Yes. Walnut Creek sits directly in the Diablo wind path, and those hot, dry offshore gusts typically arrive in fall and early winter, exactly when people first light their fireplaces after months of disuse. A flue with creosote buildup, a cracked liner, or animal nesting becomes an ember-driven fire risk under those wind conditions in a way it doesn’t in coastal-shielded Bay Area cities. We schedule our Walnut Creek pre-season inspections around the wind calendar for this reason. Book before October if you can; call (336) 863-3889 to check current availability.
