Why Hearthstone Chimney Co. of Los Angeles Is North Hills’s Preferred Chimney Cap & Crown Company
We’ve been driving to North Hills since 2014, back when much of this area was still citrus groves and horse properties. That history matters because we know which chimneys were built before seismic codes changed and which were patched in haste after 1994. Our technicians are background-checked, uniformed, and arrive with Famco and Copperfield caps in the truck, not on order from a warehouse three counties away.
North Hills homeowners call us back because we document what we find. Every Level-2 camera inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. The 90-Day Done Right Promise backs every job in writing, no arguing. If it’s not right, we come back. That’s been our way for over 42 years.

Our Chimney Cap & Crown Services in North Hills
Multi-Flue Cap Installation & Replacement
North Hills acreage properties with detached workshops often have multiple flues serving separate fireboxes or heating appliances. A multi-flue cap needs to cover every flue completely while allowing proper draft. We see too many workshops near Devonshire Street where a previous installer sized the cap for one flue and left the other exposed to Santa Ana winds and nesting birds. Our multi-flue caps are measured on-site, fabricated from Olympia Chimney or Famco components, and secured with earthquake-rated fasteners. Most installations finish in under three hours.
Custom Cap Fabrication
Standard caps don’t fit every North Hills chimney. Workshop chimneys on ranch properties often have unusual dimensions, extended flue heights, or adjacent structural elements that block off-the-shelf solutions. We measure, fabricate, and install custom caps from copper and stainless steel, matched to your chimney’s exact specifications. On a ranch property near Roscoe Boulevard, we replaced a custom multi-flue cap on a detached workshop chimney. The original 30-year-old cap had corroded around the spring anchors, causing a heavy service door to bind. We installed a custom Famco copper cap and reinforced the crown with HeatShield coating, ensuring the door operates freely and the flue stays sealed against downdrafts.
Crown Repair
The concrete crown is your chimney’s first defense against water intrusion. In North Hills, crowns built before 1994 or patched in the earthquake aftermath are failing systematically. The 91343 and 91393 ZIP codes have a concentration of post-war masonry that simply wasn’t designed for the shaking those structures took. We grind out deteriorated concrete, rebuild the crown to proper pitch and overhang, and seal with professional-grade materials. When the damage is less severe, we apply HeatShield crown coating, a specialized refractory compound that fills hairline cracks and restores waterproofing without full rebuild.
Crown Coating
For North Hills chimneys with early-stage crown deterioration, coating is the square deal. It costs less than rebuild and extends service life 10-15 years when applied correctly. We clean the crown surface, repair minor cracks, and apply HeatShield in two passes. The finish sheds water and withstands the thermal cycling that cracks untreated concrete. We recommend coating for chimneys showing surface crazing or minor spalling, especially on workshop structures where a full rebuild might exceed the value of the outbuilding.

Trusted Brands We Service in North Hills
We stock professional-grade caps and crown materials from Olympia Chimney, Famco, and Copperfield, not builder-grade substitutes from the hardware store. For North Hills customers, this means faster turnaround and no waiting for parts to ship. Our trucks carry common cap sizes, custom fabrication hardware, and HeatShield coating compound. When your workshop chimney is open to the elements and Santa Ana season is building, that inventory matters. We’ve used DuraFlex liner materials and Gelco components on North Hills jobs where the full system needed attention, not just the cap.
Common Chimney Cap & Crown Problems We See in North Hills Homes
- Heavy service door springs corrode at chimney crown attachment points. On detached workshops, the spring hardware for oversized doors often anchors through or near the crown. Moisture wicks down the anchor bolts, rusting the spring and cracking the concrete. The door goes out of balance. The cap loosens. We address both in one trip.
- Earthquake-era masonry crown cracks allow moisture into wall cavities. The 1994 Northridge quake stressed chimneys across North Hills. Many crowns were patched with non-refractory caulk by handymen in 1995. That caulk is brittle now, and water is getting behind the brick. We find this on nearly every mid-century ranch we inspect.
- Undersized multi-flue caps fail to cover all flues on workshop chimneys. A cap that covers two flues but leaves a third exposed is worse than no cap at all, it gives birds and rodents a sheltered ledge. We measure every flue and specify caps with proper coverage and clearance.
- Santa Ana downdrafts force smoke and embers through damaged caps. North Hills sits in the path of these dry, high-velocity winds. A cap with damaged screening or improper draft design won’t deflect the blast. We specify wind-resistant designs for exposed ranch properties.

What moves the number: accessibility (roof pitch, height, and whether we need scaffolding for two-story ranch homes), the extent of hidden damage beneath the crown, and whether the flue liner needs attention while we’re there. We provide no-hassle upfront pricing before any work begins. The number on the estimate is the number on the invoice.

FAQs - Chimney Cap & Crown in North Hills
Workshop chimneys are exposed to more severe weather, less frequent inspection, and heavier mechanical stress from service door hardware. The springs and hinges for oversized doors often anchor through the crown, and every cycle flexes the concrete. Moisture follows the bolt holes. Rust follows moisture. We inspect workshop chimneys with the same Level-2 camera protocol as main house flues, and we specify heavier-gauge caps with reinforced mounting for these structures. Call (844) 418-0954 to schedule - estimates are free.
A standard cap may not. Santa Ana winds in the San Fernando Valley can exceed 50 mph, and basic caps without wind-deflecting design can actually worsen downdraft by creating turbulence at the flue opening. We specify directional and wind-resistant cap designs for exposed North Hills properties, especially acreage sites with no windbreak. The right cap costs more than the box-store version. It costs less than a smoke-filled house. Call (844) 418-0954 and we’ll assess your exposure.
In most cases, yes. The earthquake-era patches we find in North Hills were often non-refractory caulk or Portland cement slurry applied in haste. Neither material handles thermal cycling, and both are failing now. Installing a new cap on a deteriorating crown is like putting a new roof on rotten decking. We inspect the crown substrate during every cap estimate and give you a plain-English verdict on whether coating, repair, or rebuild is warranted. Call (844) 418-0954 for an inspection.
You do if the flue configuration, height, or adjacent structure prevents a standard cap from seating properly. Workshop chimneys often have multiple flues at irregular spacing, extended height to clear rooflines, or nearby service doors that interfere with overhang. We measure on-site and fabricate custom caps from copper or stainless steel, typically installed within two weeks of measurement. Call (844) 418-0954 to schedule a measurement - estimates are free.
A properly rebuilt crown lasts 20-30 years. HeatShield coating extends an existing crown 10-15 years when the underlying concrete is structurally sound. The difference is the condition of the substrate. In North Hills, where earthquake-era patches and pre-seismic concrete are common, we often recommend rebuild for crowns showing through-cracking or spalling deeper than one-quarter inch. We warranty our crown work under the 90-Day Done Right Promise, and we document the before condition with photos you can see. Call (844) 418-0954 to discuss your crown’s condition.
