Why Flint Chimney Sweep Is Walnut Creek’s Preferred Chimney Repair Company

We’ve been repairing chimneys since 2002 as part of the Garrison Partners family, and the Walnut Creek jobs we take on come with the same discipline on every call. Our technicians are background-checked and uniformed. You’ll know exactly who’s walking through your door in Walnut Creek, and they’ll arrive inside the window we give you. The phone is answered by a live person around the clock, not a voicemail tree.

A lot of Walnut Creek homeowners tell us the same thing: they had a chimney company quote one number over the phone and a different one at the door. That doesn’t happen with us. Every repair comes with a written price before work begins, and every repair carries the 365-Day Done Right Promise. If it fails within a year, we return at no charge. That guarantee is in writing, on every job, no exceptions.

We know Walnut Creek’s housing stock: the 1960s and ’70s ranch homes east of I-680, the older masonry chimneys near downtown, and the newer builds up against the ridge line. That local familiarity means we know what to look for before we even climb the ladder.

Chimney Cap Replacement in Walnut Creek

Chimney Cap Replacement in Walnut Creek runs $340 – $580 for a standard stainless cap with spark screen installed, and it’s one of the most common repairs we do in this area. The cap sits on top of the flue and keeps water, birds, and debris out. In Walnut Creek, where much of the housing stock backs up to the wildland-urban interface and its oak canopy, the cap does a second job: it acts as a spark arrestor that screens embers before they hit your roof or the dry hillside beyond.

What a Walnut Creek cap actually protects

A rusted or missing cap lets rain fall straight into the flue, which accelerates mortar decay and flue liner cracking. We regularly pull oak litter, acorns, and the occasional squirrel or bird nest off caps in Northgate and Walnut Heights. On one Northgate job, a burned-through 1970s cap had been letting embers and weather into the flue for years. The camera inspection that followed showed a cracked clay liner and second-degree creosote flaking off the smoke chamber. The homeowner had been one dry season from a real problem.

When you need one

If your cap is rusted through, missing its spark screen, or pulling away from the crown, replace it. If you can see daylight through the cap body or the mesh is torn, don’t wait for the first winter rain to find the crack. We stock stainless caps from Famco and Copperfield, and most Walnut Creek replacements are done in a single visit.

Chimney Liner Installation in Walnut Creek

Chimney Liner Installation in Walnut Creek runs $1,200 – $1,900 for a typical stainless reline with a DuraFlex or Copperfield liner, including the camera inspection beforehand. The flue liner is the inner pipe that channels smoke and combustion gases safely out of your house. When it cracks or spalls, those gases can leak into the wall cavity or living space.

How we know it’s needed

We don’t sell liners on a guess. Our Level 2 camera inspection shows you exactly what’s going on inside the flue, on a screen, in real time. If the liner is cracked at the firebox or flaking in the smoke chamber, we’ll show you the footage before we quote a reline. In Walnut Creek’s pre-1980s ranch homes, we see clay tile liners that have been drying and cracking for decades. A cracked flue liner is a carbon monoxide risk, full stop. The fix is a stainless liner sized for your existing flue.

Third-degree creosote and why a brush won’t cut it

Some older Walnut Creek chimneys have third-degree creosote glazing, which is baked-on, tar-like creosote that hardens into a shell on the flue wall. A brush passes right over it. Those flues need either a chemical treatment like Gelco or a HeatShield resurfacing, depending on what the camera shows. We’ll tell you plainly which one applies and what it costs before you commit.

Trusted Brands We Service in Walnut Creek

We install and repair the brands that meet our standard, and we keep common parts stocked so Walnut Creek customers aren’t waiting on a shipment from a warehouse. That includes stainless liners and caps from Copperfield and Famco, plus DuraFlex liner systems for relines and Gelco for creosote removal on glazed flues. You can verify the quality of these materials independently, which we encourage. A repair is only as good as the parts that go into it, and we don’t cut corners on material to pad a bid. You’ll see the brand name on the quote before we start.

Common Chimney Repair Problems We See in Walnut Creek Homes

• Rusted caps letting embers and rain into the flue. In the wildland-urban interface that stretches from Walnut Creek up into the East Bay hills, a cap with a torn spark screen is doing no one any good. We’ve pulled oak litter and acorn shells out of flues all over this city.
• Spalling and freeze-thaw damage on mortar crowns. Walnut Creek chimneys under heavy oak or walnut canopy stay damp longer, and our winter freeze-thaw cycles widen hairline cracks every season. What starts as a cosmetic crack becomes a path for rainwater into the brick.
• Third-degree creosote glazing on older masonry flues. The 1960s and ’70s ranch homes east of I-680 and up Ygnacio Valley Road often have clay tile liners that have been building up hardened creosote for decades. A standard sweep won’t touch it.
• Damper frames and throat mortar failing on shaded chimneys. Roof debris and shade from mature oaks keep the crown and throat area damp, which leads to spalling throat mortar and dampers that won’t seat. You’ll notice a draft when the fire is out.
