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.

We know Danville’s chimneys because we’ve been inside hundreds of them. The sprawling custom homes off Camino Tassajara, the gated enclaves around Blackhawk, the older ranches near Diablo Road: each neighborhood has its own failure patterns, and we quote accordingly. No flashlight glances, no vague warnings. A camera goes down every flue, and you see exactly what we see.
Why Emberly Chimney Cleaners Is Danville’s Preferred Chimney Cap & Crown Company
Danville homeowners tend to ask the same question before they book: “Can you show me what’s actually wrong?” That’s the question our process was built for. Every visit includes a camera-scan inspection under NFPA 211 Level 2 standards, and the photo record is yours to keep. That’s Clause 4 of the Haven Standard, and we’ve done it that way since 2009. Not as an upsell. As the default.
Our techs are background-checked, uniformed, and assigned by name. You’ll get a text when they’re on the way. The written price, written scope, and written warranty arrive before work starts, never after. H.A.V.E.N. Clause 1: Have it in writing. If something isn’t done right, the 365-Day Done Right Promise means we come back and make it right. No argument, no invoice.
Corrine Halstead leads the crew, and she’s built the Danville book of business one camera scan at a time. What impresses this market isn’t years on a van magnet. It’s the photo of the rusted seam, the measurement of the crown’s moisture migration, the cap spec that actually fits the flue cluster. We show all of it.
Our Chimney Cap & Crown Services in Danville
This is the short version of what we actually do on Chimney Cap & Crown work in Danville. The long version happens on your roof, with measurements in hand.
Cap Replacement
Danville’s original caps on 1980s zero-clearance units rust through at the seams, usually within 20 to 25 years. Once that seam opens, acorn debris and leaf litter from mature valley oaks find their way into the flue liner. We remove the old cap, measure the termination precisely, and install a replacement sized for the actual flue dimensions, not a universal fit. In Danville, standard single-flue cap replacement runs $225-$485 depending on flue size and access.
Custom Cap
Many Danville estate homes near Blackhawk and along the Las Trampas Ridge interface have wide, multi-flue terminations that standard caps simply won’t cover. We fabricate custom caps to fit the exact flue cluster, including spark arrestors sized for Diablo wind ember conditions. When an off-the-shelf cap leaves gaps or underhangs the crown edge, it’s not a cap: it’s an invitation for water and debris. Custom work typically runs $650-$1,400, quoted in writing before fabrication starts.
Multi-Flue Cap
Properties with two to four fireplaces per structure are common throughout Danville, particularly in the hillside developments built between 1978 and 2000. A multi-flue cap covers the full termination while keeping each flue properly vented and separated. We see a lot of homes where a single-flue cap was jammed onto a multi-flue crown years ago, leaving one flue open to weather. Multi-flue cap installation in Danville generally runs $550-$1,150 depending on overall crown width and flue count.
Crown Repair & Crown Coating
Large masonry crowns on multi-flue estate chimneys develop hairline cracks, then spalling, from decades of mid-30s winter freeze-thaw cycles. Water migrates into the smoke chamber and damper area. We repair the crown with proper slope and overhang, then seal it. For crowns that are structurally sound but porous, we use Gelco crown coating: a flexible sealant that bridges micro-cracks and stops water absorption before it becomes a rebuild. Crown repair in Danville runs $385-$700; coating alone runs $285-$550.

We stock and install Copperfield caps, DuraFlex liners, and HeatShield repair materials, and we spec Gelco for crown sealing. These are the same materials we’d put on our own homes, sourced through Haven’s buying network to keep customer prices honest. For Danville customers, that means no waiting on a weeks-long special order for a common cap size: we keep the high-turnover inventory in our Bay Area shop and dispatch to Danville on a regular schedule. If you have a preferred brand or an existing cap you want matched, tell us during the quote. We’ll spec it accordingly.
Common Chimney Cap & Crown Problems We See in Danville Homes
- Rusted-through seams on original 1980s zero-clearance caps. The cap looks intact from the ground, but the seam has opened and acorn litter from valley oaks is dropping straight into the flue. In Blackhawk and other mature-tree neighborhoods, this is the single most common failure we document.
- Spalling crowns on oversized estate chimneys. Multi-flue crowns poured decades ago take freeze-thaw abuse every winter. Once spalling starts, the crown sheds concrete and absorbs water. The fix is resurfacing and coating, not shoving caulk into the cracks.
- Improperly sized caps on multi-flue terminations. A previous owner or a handyman installed a single-flue cap over a two- or three-flue crown. Now one flue is open to weather and debris. We see this repeatedly in Danville because so many homes have non-standard terminations.
- Missing spark arrestors during Diablo wind season. When fall Diablo winds push embers across the eastern foothills, a cap without a proper spark arrestor is a genuine fire-safety gap. Homes along the Blackhawk and Las Trampas Ridge edge face the highest exposure, and cap condition there is a primary check, not an afterthought.
Pricing for Chimney Cap & Crown in Danville, CA
Here’s the honest Danville market picture. Standard cap replacement: $225-$485. Crown repair: $385-$700. Crown coating with Gelco: $285-$550. Custom or multi-flue caps: $550-$1,400 depending on flue count, crown width, and access. What moves the number is flue configuration more than zip code. A two-flue zero-clearance setup in a Blackhawk custom home costs more than a single-flue ranch fireplace off Diablo Road because the termination is wider and the access is steeper. You’ll get an exact written price after we measure, not after we start. Estimates are free, and we’ll honor the quoted price. Call (980) 580-8641 to book.

FAQs - Chimney Cap & Crown in Danville
Danville’s 1980s and 1990s custom-home boom, especially around Blackhawk and the hillside lots off Camino Tassajara, produced a high concentration of large estate homes with two to four zero-clearance fireplaces per property. Each of those units has its own flue termination, often grouped on one wide masonry crown. Standard single-flue caps don’t span the width, so a proper multi-flue or custom cap is required. A multi-flue cap in Danville runs $550-$1,150. Call (980) 580-8641 and we’ll measure your exact termination.
Diablo winds hit the eastern foothills hardest, especially near Blackhawk and the Las Trampas Ridge interface, where fall wind gusts can exceed 40 mph. Those winds carry embers from the wildland interface and drive debris across roofs at speed. A cap with a missing or damaged spark arrestor becomes an ember intake. A crown with micro-cracks gets wind-driven rain forced into the masonry. We treat cap and crown condition as a fire-safety issue during the September-November window, not just a water-damage concern. Cap replacement starts at $225 in Danville.
Yes, and this is one of the more specific realities of owning a chimney in Danville. Mature valley oaks common in Blackhawk and other established neighborhoods drop acorns and leaf litter for months each fall. Those materials find open seams and uncapped flues fast. Homes under heavy oak canopy should have caps inspected at least once annually and cleaned of packed debris each fall, before burn season starts. We include cap inspection with every sweep. Call (980) 580-8641 for a written quote.
In most cases, yes. If the crown still has structural integrity and proper slope, we resurface the spalled areas, rebuild the overhang where needed, and seal with Gelco crown coating. Full tear-out and re-pour is reserved for crowns that are so far gone they’ve lost their pitch or are actively shedding large sections. Resurfacing and coating runs $385-$700 in Danville; a full re-pour is quoted in writing after camera inspection of the masonry. We’ll show you photos either way before recommending a rebuild.
Yes. Zero-clearance units, which dominate Danville’s 1980s-1990s housing stock, use manufactured termination caps designed for their specific brand and flue diameter. Many are now 30 to 40 years old and past their typical 20 to 25-year lifespan, so cracked lids and rusted seams are routine finds during inspection. Masonry chimneys take custom or multi-flue caps sized to the crown. We stock Copperfield caps and can match most zero-clearance brands on the same visit. Call (980) 580-8641 for a free estimate with a camera scan.
