Fast, Reliable Chimney Cap & Crown Across Lennox
A chimney cap and crown repair in Lennox typically runs $280-$650 for standard work, with most jobs completed in a single visit and same-day service available when you call (844) 803-1545. We’ve been driving to Lennox since 1984, and we know the difference between a chimney that needs a simple cap swap and one that’s been collecting jet exhaust residue under the LAX flight path for fifteen years. Our Chimney Cap & Crown team carries Gelco and Olympia Chimney caps on the truck, along with HeatShield crown coating material, so we don’t waste your afternoon running to a supplier.
Why Hearthstone Chimney Co. Is Lennox’s Preferred Chimney Cap & Crown Company
Lennox sits in a pocket of 90304 that other chimney companies drive through on their way to somewhere else. We don’t. Russell Haines built this company on the principle that a craftsman shows up where he’s needed, and Lennox has been on our route for over four decades.
Our technicians know the tight lot lines off Prairie Avenue and the Inglewood Avenue corridor, where post-war bungalows sit shoulder-to-shoulder and roof access means threading a ladder between structures with inches to spare. We’ve replaced caps on chimneys you can almost touch from the neighbor’s driveway. That familiarity saves time, and it keeps your gutters and roof tiles intact.
When you call (844) 803-1545, a live person answers. Not a callback queue, not an app. Someone who can dispatch a background-checked, uniformed technician to Lennox today if the situation calls for it. Most jobs finish in one visit, with upfront pricing that matches the final invoice.
Our 90-Day Done Right Promise applies in Lennox exactly as it does everywhere else: in writing, no arguing. If the cap leaks or the crown coating fails because we missed something, we come back and make it right.
Our Chimney Cap & Crown Services in Lennox
Cap Installation
New cap installation in Lennox runs $320-$480 for a standard single-flue stainless steel unit, including proper measuring and storm collar sealing. Most Lennox chimneys were built without caps originally, or with cheap galvanized hoods that rusted out decades ago. We size each cap to your flue dimension and roof pitch, accounting for the close neighboring structures that can create odd wind patterns in this dense housing stock. A proper cap stops the jet exhaust particulates that drift down from the LAX approach corridors from entering your flue in the first place.

Cap Replacement
Cap replacement in Lennox costs $280-$420 when the existing mounting flange is still sound, or $380-$550 if the flue tile itself has deteriorated and needs rebuilding before the new cap seats correctly. We see a lot of replacement jobs near Lennox Boulevard and 104th Street, where the original 1960s caps finally gave way after sixty years of marine layer moisture and thermal cycling. We haul the old cap away and leave the roof clean.

Crown Repair
Crown repair in Lennox typically falls between $450-$680 for a standard pour-and-seal job on a single-flue chimney. The 1940s through 1960s brick chimneys in this area almost all have concrete crowns that were mixed too wet or troweled too thin from the start, and forty years of salt air has done the rest. We cut back to sound concrete, form a proper wash with drip edges, and seal with professional-grade materials so water sheds away from your brickwork instead of soaking into it.

Crown Coating
Crown coating with HeatShield or similar professional-grade refractory material runs $380-$520 in Lennox and can add ten to fifteen years of service life to a crown that’s cracked but still structurally sound. This is often the right call for Lennox homeowners who want to defer a full rebuild without gambling on water intrusion through hairline cracks. We document the before condition with camera photos you can see, then apply the coating to manufacturer spec.

Multi-Flue & Custom Cap Options
Multi-flue caps and custom fabricated solutions start around $580-$950 in Lennox, depending on span and material. Some of the duplex conversions along Firmona Avenue have unusual flue clustering or offset chimneys that need custom measurement. We template on site and quote before fabricating, so you know the exact number before we order.

Trusted Brands We Service in Lennox
We stock Gelco and Olympia Chimney caps in the most common Lennox sizes, along with Famco hardware and HeatShield crown coating systems. These aren’t builder-grade substitutes from a big-box store. They’re the brands that other chimney professionals use, and we keep inventory moving through our Los Angeles warehouse so Lennox customers don’t wait two weeks for a part to ship. When your cap has blown off in a Santa Ana wind and rain is forecast, that local stock matters.
Common Chimney Cap & Crown Problems We See in Lennox Homes
- Missing or rusted caps from the original 1950s-1960s construction. Lennox bungalows were built fast and cheap after WWII, and many never got a proper cap at all. What passed for a rain hood has long since corroded into a rust ring around the flue tile, leaving the chimney open to debris, animals, and that distinctive oily carbon film we find near the LAX flight corridors.
- Crumbled crown concrete from decades of marine layer exposure. The cool, damp air that rolls in off Santa Monica Bay doesn’t freeze hard, but it seeps. We’ve lifted caps in Lennox to find crown surfaces that look like crumb cake, with water having worked through every cold joint and freeze-thaw cycle since the Eisenhower administration.
- Bird and rodent nesting in uncapped flues. Because Lennox fireplaces sit cold most of the year, swifts, sparrows, and the occasional roof rat treat open chimneys like ready-made housing. A proper cap with mesh screening ends that, and we clean out what’s there before we install.
- Damper corrosion from disuse. The same mild climate that makes Lennox pleasant to live in means dampers rust shut or hang open for years without a homeowner noticing. A cap installation often reveals this secondary problem, and we flag it with photos and a plain-English verdict before we close up.
