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 Repair Across Orinda
Chimney repair in Orinda, CA typically runs $180 – $1,750 depending on what’s actually wrong, and most caps, flashing, and crown work can be booked within a week. We’re Flint Chimney Sweep, part of the Garrison Partners family since 2002, and we’ve worked on enough Orinda homes to know the hills here age a chimney differently than flatland houses. If you’re seeing water stains near the firebox, hearing animals in the flue, or smelling smoke when the fire’s off, call (830) 251-4560 and we’ll put a plan in writing before any tools come off the truck.
Why Flint Chimney Sweep Is Orinda’s Preferred Chimney Repair Company
Our crews know Orinda’s terrain, and that matters more than people expect. Steep lots off Miner Road, narrow drives above Moraga Way, older ranches built into the hillside off Rheem Boulevard. Each one changes how we stage ladders, route a camera, and protect the roofline. We run background-checked, uniformed techs on every call, and the person who answers when you phone is a live human, 24 hours a day. Not an answering service. Not a callback form.
Every repair carries the 365-Day Done Right Promise: a written guarantee good for one full year from the service date. If a covered repair fails inside that year, we return at no charge. That’s not a marketing line. It’s printed on the invoice you sign before work starts.
The Garrison Standard governs how we operate, same as every Garrison Partners location: written price before work begins, scope documented, nothing added at the door. Orinda homeowners tell us the written quote is the reason they called us instead of the last company that quoted over the phone and billed higher on site.
Chimney Cap Installation in Orinda
Chimney cap installation in Orinda is the repair we recommend most often after an inspection, because a missing or undersized cap is what lets hill rain and oak debris into the flue in the first place. A new stainless cap for a standard single-flue chimney in Orinda typically runs $280 – $450 installed, depending on the flue tile size and roof pitch.
The fix is straightforward: we measure the flue, set a cap sized for the tile or liner, and fasten it so raccoons and squirrels cannot pry it loose. On Orinda’s steeper lots, we also check that the cap is set level on a sloped crown so water sheds away from the flue instead of pooling.
Liner-Matched Sizing
We don’t sell a one-size cap. A cap too small restricts draft, and one too big lets rain angle in under the mesh. We size the cap to the flue tile or the DuraFlex liner if the home has one, then verify the draft with a smoke test before we pack up.
Wet-Chimney Prevention
A capped chimney still gets wet if the crown beneath it is cracked. When we install a cap on an older Orinda chimney, we document crown condition with photos and tell you plainly whether the crown can wait or needs sealing the same visit. No pressure. Just the facts in the report.
Chimney Cap Replacement in Orinda
Chimney cap replacement in Orinda usually comes down to rust, storm damage, or an animal that tore through the mesh. A replacement cap for a single-flue Orinda chimney typically runs $320 – $520, including removal of the old cap and proper disposal.
The mistake we see most is a homeowner buying a cap at a hardware store and setting it on the flue without sealing or fastening. Orinda’s winter wind loads, especially on north-facing ridges above Happy Valley Road, will take an unsecured cap off the chimney inside one season. We remove the old unit, check the flue tile edge for chipping, and mount the new cap with mechanical fasteners, not gravity.
What Gets Replaced
Beyond the cap itself, we inspect the spark arrestor mesh, the mounting collar, and the flue tile lip. If the old cap rusted out, water has been entering there for months, and the top flue tile often shows spalling. Replacement includes that assessment and a photo of exactly what we found before and after.
When a Cap Upgrade Makes Sense
If a Orinda homeowner is replacing a damaged cap and the chimney has no liner, we’ll recommend a HeatShield or DuraFlex liner at the same time when it is genuinely needed, and show you the camera footage that supports it. If the flue is sound, we say so and do the cap only. We’d rather lose a liner sale than sell one the chimney doesn’t need.
Trusted Brands We Service in Orinda
We service and install professional-grade chimney products from brands homeowners and inspectors actually know: HeatShield for flue resurfacing, Gelco caps, Olympia Chimney components, and Famco hardware. When a Orinda customer needs a part, we source it from these manufacturers rather than whatever generic fitting is on the shelf. That means the cap, damper, or liner we install on your Orinda chimney is the same brand an inspector would specify in a report, and parts arrive faster because our Bay Area office coordinates directly with suppliers.
Common Chimney Repair Problems We See in Orinda Homes
- Third-degree creosote. After a wet Orinda winter, first-degree creosote that sat through spring and summer can harden into a tar-like glaze on the flue liner. A standard brush cannot remove it. We treat third-degree creosote with a chemical application or a rotary removal system, and we’ll show you the before and after on camera.
- Cracked crowns and failed flashing. Hill rain driven against the north and west sides of Orinda chimneys works into the crown and flashing joints over a few seasons. By the time a homeowner sees a stained ceiling near the firebox, water has been moving through the smoke chamber for months. We repair crowns with proper crown compound and replace flashing in sections, not patches.
- Animal nests and shifted caps. A skipped annual inspection on an Orinda chimney with mature oaks nearby is an open invitation. Squirrels and raccoons work caps loose, then nest in the flue. The first cool-evening fire pushes smoke back into the living room because the nest blocks draft. We remove the nest, clean the flue, and reset or replace the cap.
- Blocked or deteriorating draft. Older Orinda homes built with unlined masonry chimneys often lose draft as mortar erodes inside the flue. A homeowner notices the fireplace never draws well, or the smoke smell lingers after a fire. We run a camera down the flue, locate the restriction or erosion, and give you a repair scope in writing with photos.
Pricing for Chimney Repair in Orinda, CA
Here’s what Orinda homeowners can expect on repair pricing, and we’ll put the exact figure in writing before we begin. Cap installation runs $280 – $450. Cap replacement runs $320 – $520. Crown repair and resealing typically runs $400 – $850 depending on the crown’s surface area and whether we build up damaged sections or apply a full coat.

Flue relining with a DuraFlex or HeatShield system runs $3,200 – $6,500 on a standard one-story Orinda chimney, and we only recommend it when camera footage shows the original liner or masonry has failed.

FAQs About Chimney Repair in Orinda
Once a year, before burning season, and especially so in Orinda where north-facing slopes and oak canopy keep chimneys shaded and damp for months at a time. The inspection costs less than most repairs, and a camera inspection catches crown cracks and liner erosion while they’re still cheap to fix. If you’ve skipped more than one season, call (830) 251-4560 and we’ll get you on the schedule without a pitch.
No. The camera inspection is part of the service, not an add-on. We run a camera down the flue on every Orinda repair we perform, and you get a photo report of what we found, what it means, and what actually needs doing. If the flue is sound, you’ll see that on the photos and we’ll tell you plainly.
First-degree creosote is the flaky, sooty residue a brush removes. Third-degree creosote is a hardened, tar-like glaze that builds up after first-degree creosote sits through wet seasons without a cleaning. On an Orinda chimney that’s gone two or three winters between sweeps, third-degree glaze is common. A standard brush cannot remove it. We use chemical or rotary methods to break it down, and we’re glad to show you the camera footage before and after.
Yes, if it’s a sudden change. Smoke entering the room instead of going up the flue points to a blocked flue, usually a nest, a shifted cap, or heavy creosote narrowing the draft. It can also indicate a failed damper. You’re pulling carbon monoxide into the living space, so stop using the fireplace until we inspect it. Call (830) 251-4560 and we’ll get a tech to Orinda with a camera. Most blockages are resolved the same visit.
We replace it. A damaged cap lets rain, debris, and animals into the flue, which leads to more expensive repairs down the line. We’ll assess whether the cap is the only failure or whether the crown and flashing also need work, then give you a written price for the cap replacement before we start. If the cap is the only issue, that’s all we’ll quote. No bundled upsell.
If your Orinda chimney hasn’t been inspected this year, or you’re seeing water, smoke, or animals where they shouldn’t be, call Flint Chimney Sweep at (830) 251-4560. We’ll schedule a visit, put the price in writing, and stand behind the work for a full year.
