Fast, Reliable Chimney Cap & Crown Across Novato
Chimney cap and crown repair in Novato typically costs $340-$890 depending on whether you need a simple cap replacement or full crown rebuild, and most jobs are completed in a single visit. If you’re calling from San Marin, Hamilton, or Black Point, our Chimney Cap & Crown in Novato crew can usually be there within 24-48 hours. We’ve been driving to Novato from our San Francisco base for over 42 years, and we know the local housing stock: the 1960s-1980s tract homes with original zero-clearance fireplaces, the converted military buildings at Hamilton with their non-standard flues, and the way Novato’s inland valley traps cold air that keeps chimneys wet longer than coastal Marin. Call (855) 408-5567 and a live person will answer, any hour.
Why Hearthstone Chimney Co. of San Francisco Is Novato’s Preferred Chimney Cap & Crown Company
Novato homeowners tend to stay put. They’ve lived in the same house for twenty, thirty, sometimes forty years. They remember the contractor who didn’t show, the one who left a mess, the one whose “warranty” turned out to be a voicemail box that no one checked. We understand that. Warren Eckhart built this company in 1984 on the idea that a craftsman should stand behind his work without being asked twice.
Our Novato customers find us through neighbors, not ads. They mention the same things in reviews: the technician arrived in a clean uniform, took photos of the crown damage they couldn’t see from the ground, and explained the repair in plain English. No upsell. No rush. The 90-Day Done Right Promise in writing, no arguing. If it’s not right, we come back.
Response time to Novato runs 24-48 hours for standard calls, same-day for water intrusion or structural crown damage that threatens the roof. We carry Gelco and Olympia Chimney caps in common sizes, plus custom-fabrication capability for the odd flue dimensions we encounter in Hamilton’s converted barracks. Most jobs finish in one visit. The number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Novato
Cap Installation
New cap installation in Novato runs $280-$520 for standard single-flue galvanized or stainless steel units. We recommend stainless in Novato. The Petaluma Gap funnels salt-laden marine air through the valley, and galvanized steel caps show rust and mesh sagging within 3-5 years here instead of the typical 7-10. For homes in Black Point with north-facing chimneys that never fully dry, stainless steel or copper pays for itself. We size on-site with a tape measure and level, never guess from a photo.
Cap Replacement
Removing a rusted or wind-damaged cap and installing a new one is straightforward until it isn’t. We’ve pulled caps off Novato chimneys where the original installer used the wrong base dimension, leaving a 3/4-inch gap that funneled rain onto the crown for a decade. In San Marin’s 1970s ranches, we often find factory-built fireplace caps that have corroded through at the seams. Replacement with a proper fit, sealed base, and mesh spark arrestor runs $340-$580. We haul the old one away.
Crown Repair
The crown is the concrete slab that tops your masonry chimney, and it’s where water does its worst work. Novato’s cold-air inversions trap moisture against chimney masonry for days longer than in Tiburon or Sausalito. Freeze-thaw cycles crack poorly sealed crowns, especially on north-facing roofs. Crown repair, including demolition of damaged concrete, forming and pouring new high-strength mortar with expansion joints, runs $620-$890. We use professional-grade materials from Copperfield and Famco for forming and reinforcement.
Crown Coating
For crowns with minor cracking or surface spalling, elastomeric coating is a sound alternative to full rebuild. We clean the crown, fill cracks with flexible sealant, and apply two coats of vapor-permeable crown sealer. In Novato’s climate, we recommend recoating every 4-6 years, sooner if the crown was never properly sealed. Crown coating runs $280-$440. It’s preventive maintenance that extends the life of sound masonry by a decade or more.
Multi-Flue Cap
Homes with two or more flues sharing a chimney chase need a multi-flue cap that covers the entire crown, not individual caps per flue. This is common in Novato’s larger 1970s-1980s homes and in Hamilton’s converted military duplexes. A stainless steel multi-flue cap with proper overhang and mesh sides runs $480-$780 installed. We measure the chase, fabricate or order to fit, and seal the mounting flange to the crown to prevent water intrusion at the cap base.
Custom Cap
Standard caps don’t fit Hamilton’s institutional flues. We’ve measured flue tiles in converted military buildings at 15×20 inches, 18×24 inches, round 14-inch diameters - sizes no hardware store stocks. Custom stainless or copper caps, fabricated to your flue dimension with proper draft clearance and mesh, run $520-$940 depending on metal gauge and finish. We template on-site, fabricate locally, and return to install. Two trips, but the cap fits.

Trusted Brands We Service in Novato
We stock and install professional-grade caps and crown materials from Gelco, Olympia Chimney, and Famco. Gelco’s stainless single-flue caps with welded seams hold up to Novato’s salt air without the galvanic corrosion we see on cheaper units. Olympia Chimney’s multi-flue line covers the wider chases common in 1970s Novato construction. Famco supplies the elastomeric crown coatings and flashing components we use for repairs. We don’t substitute builder-grade materials to hit a price point. The cap that goes on your chimney is the same cap we’d put on our own.
Common Chimney Cap & Crown Problems We See in Novato Homes
- Salt-air corrosion of galvanized caps. The Petaluma Gap pushes marine air through Novato’s valley, and galvanized steel caps rust through at the seams within 3-5 years. We replace them with stainless or copper, period.
- Freeze-thaw crown cracking on north-facing chimneys. Novato’s inland valley holds cold, moist air longer than coastal Marin. Crowns that never dry out develop spider cracks that widen each winter. Coating or rebuild before water reaches the flue liner saves the chimney.
- Ill-fitting caps on Hamilton’s non-standard flues. Converted military buildings have flue tiles sized for institutional heating equipment. A standard 8×13 or 13×13 cap sits like a hat on a horse, leaving gaps for rain and squirrel entry. Custom fabrication is the only proper fix.
- Thermal cycling damage on original zero-clearance fireplaces. San Marin’s 1960s-1980s ranch homes have factory-built fireplaces now 40-50 years old. The metal crown assemblies fatigue, crack at corners, and leak. We replaced one last month: the homeowner noticed water stains on the ceiling, and our inspection found the crown rusted through at the weld.

FAQs - Chimney Cap & Crown in Novato
Salt-laden marine air from the Petaluma Gap accelerates corrosion of galvanized steel caps and mesh, causing premature rust and sagging within 3-5 years rather than the typical 7-10. We install stainless steel or copper caps in Novato as standard practice, not upgrades. Call (855) 408-5567 and we’ll assess what you have now.
Yes, probably. Converted military buildings in Hamilton often have flue tiles originally designed for institutional use, with wider diameters that cause chronic downdraft when paired with standard residential inserts. Standard off-the-shelf caps won’t fit or seal properly. We template non-standard flues on-site and fabricate custom caps to match. Warren Eckhart has handled dozens of these Hamilton conversions personally.
Every 4-6 years for crowns in good condition, sooner if the original crown was never sealed or if your chimney faces north and stays damp. Novato’s inland valley traps cold air and moisture longer than coastal Marin, promoting freeze-thaw damage. A coated crown lasts decades; an uncoated one cracks and leaks in 5-10 years. We inspect crown condition during every cap service and tell you straight if coating will suffice or if repair is past due.
A stainless steel single-flue cap with proper draft clearance and a mesh spark arrestor, sized to the manufacturer’s flue specification. Many San Marin homes have factory-built fireplaces now 40-50 years old, well past their typical service life. We check the flue liner condition with our camera before capping; a cap on a deteriorated liner hides the problem until it’s expensive. The right cap plus a sound liner is the combination that lasts.
Yes. We template, fabricate, and install custom caps for flue dimensions that don’t match residential standards. This is routine for us in Hamilton’s converted military buildings, where we’ve encountered round 14-inch flues, 15×20 rectangles, and other institutional sizes. Custom caps run $520-$940 installed. Call (855) 408-5567 to schedule a template measurement.
