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.

AfterChimney Cap & Crown in San Gabriel: What It Costs and What Actually Fails
A chimney cap replacement in San Gabriel typically runs $340 to $680 including materials and labor. A crown repair, done correctly with a proper flexible sealant, usually lands between $450 and $900 depending on how much of the existing concrete needs to be reconstructed. If you’re lighting a fireplace in one of San Gabriel’s mid-century brick chimneys, the cap and crown are the two components most likely to be hiding damage from the 1987 Whittier Narrows earthquake, and the fix is almost always less expensive than what happens if you ignore it.
We’re Emberly Chimney Cleaners, and we’ve inspected more than 38,000 chimneys since 2009. Every one of those visits included a camera down the flue and a written price before anyone touched a tool. That’s how we work in San Gabriel, from the Mission District to the tracts along Valley Boulevard and up toward the historic neighborhoods near San Gabriel High School. If you want a straight answer about your chimney cap or crown, call (980) 580-8641 and we’ll schedule the inspection.
Key Takeaways
- Cap replacement in San Gabriel runs $340-$680; crown repair runs $450-$900.
- Most caps and crowns on pre-1970 San Gabriel chimneys were damaged in the 1987 quake and cosmetically patched, never properly rebuilt.
- We include a camera-scan inspection and photo record on every visit, per Clause 4 of the Haven Standard.
- Written price, written scope, and written warranty before work starts. Always.
Why Emberly Chimney Cleaners Is San Gabriel’s Chimney Cap & Crown Team
We built our name on documentation. Since 2009, Emberly Chimney Cleaners has operated under the Haven Standard, and Clause 4 says every job includes a camera-scan inspection and a photo record you keep. That matters in San Gabriel because the damage we’re looking for is almost never visible from the ground. A cap can look straight from the driveway and still be leaking around a cracked crown seam every time the marine layer rolls in.
Our crews know San Gabriel’s housing stock. We work on the 1940s bungalows off Las Tunas Drive, the 1950s ranches near Coolidge Elementary, and the brick chimneys clustered around the San Gabriel Mission. The same failure patterns show up again and again: cracked crowns, loose galvanized caps, spalling brick, and flue liners with hairline seismic fractures that only a camera shows. Corrine Halstead leads our team, and she’s built the company around the idea that you should see what we see before you spend a dollar. That’s why we hand you the camera record, not a verbal summary.
Background-checked, uniformed technicians show up in a marked vehicle, on schedule, with a text before we arrive. We’re independently owned and operated under the Haven Standard, with license information on every page. Calls are answered by a live person, 24 hours a day.
Our Chimney Cap & Crown Services in San Gabriel
Here’s what we actually do on San Gabriel rooftops, and what each service addresses. The Chimney Cap & Crown team handles all of these, and every job starts with the camera going down the flue so we can show you what’s failing before we touch anything.
Cap Installation
New cap installation in San Gabriel usually runs $340 to $520 for a standard single-flue stainless unit. We stock stainless steel caps from Olympia Chimney and Famco because galvanized steel corrodes faster in coastal air and against the minerals in older brick. A properly sized cap keeps Santa Ana-driven debris out of the flue and stops birds from building nests during the months when the fireplace sits idle.
Cap Replacement
When we find a loose, rusted, or seismically shifted cap on a San Gabriel chimney, replacement runs $380 to $680 depending on flue size and whether we need a custom fit. The 1987 quake shifted a lot of caps just enough to break the seal against the crown, and once that seal fails, water follows. We remove the old unit, inspect the crown underneath, and install a cap sized to the flue tile with mechanical fasteners, not caulk alone.
Crown Repair
Crown repair is the service we recommend most often in San Gabriel, and it runs $450 to $900. A concrete crown that cracked during the earthquake keeps cracking because concrete doesn’t reseal itself. We grind out the failed material, rebuild the crown with a proper slope and drip edge, and seal it with a flexible coating like Gelco so it can move with the chimney through seasonal temperature swings without splitting open again.
Crown Coating
A crown coating on its own runs $300 to $550 and works best when the crown is structurally sound but starting to show surface spalling. For San Gabriel’s older brick chimneys, we usually pair the coating with a camera inspection of the flue liner, because a crown that’s absorbing water is often sitting above a liner that’s already cracked from seismic movement. Coating the crown without checking the flue is a temporary fix, not a repair.
Multi-Flue and Custom Caps
Homes with two or more flues, or with unusual flue tile configurations common in San Gabriel’s custom mid-century builds, need a multi-flue or custom cap. Pricing starts around $520 and runs up to $1,100 for complex layouts. We measure on site, order through Haven’s buying network to keep the materials cost honest, and install with a written warranty on the unit and the workmanship.

BeforeAfterTrusted Brands We Use in San Gabriel
We install caps from Olympia Chimney, Famco, and Copperfield, and we use Gelco and DuraFlex materials for crown repair and rebuilds. These aren’t whatever’s left on the truck. We spec stainless steel for cap and crown work because San Gabriel’s coastal moisture and the mineral content in older brick chew through galvanized quickly. Having access to these manufacturers through Haven’s buying network means we can give San Gabriel homeowners a written price that reflects what the materials actually cost, not a markup built on vagueness. Parts for common San Gabriel chimney configurations are usually available within a few days, and we’ll give you a written lead time before you commit.
Common Chimney Cap & Crown Problems We See in San Gabriel Homes
- Seismic crown cracks from the 1987 Whittier Narrows quake. The quake’s epicenter was just miles away in Rosemead, and San Gabriel’s unreinforced brick chimneys absorbed heavy shaking. Crowns cracked, caps shifted, and many homeowners took an insurance payout for tuckpointing that never addressed the structural damage underneath.
- Spalling brick from trapped moisture. A crown with hairline cracks lets marine-layer moisture into the brick, and San Gabriel’s mild winters mean that moisture sits there for months. The brick face starts popping off in flakes, which widens the entry point and accelerates the damage.
- Debris and nesting from Santa Ana winds and mature tree canopy. The San Gabriel River corridor’s trees drop leaves and twigs onto chimney crowns, and October winds pack debris into uncapped or loose-capped flues. We regularly pull enough dry material out of capped chimneys near Valley Boulevard to refill a five-gallon bucket.
- Rusted galvanized caps on 1960s and earlier chimneys. Original galvanized caps were never meant to last 60 years in this climate. By the time a San Gabriel homeowner notices the rust streaks on the brick, the cap is usually loose enough to lift off by hand.

FAQs - Chimney Cap & Crown in San Gabriel
You usually can’t tell from the ground, which is why we camera-inspect every chimney. A cap that shifted in the quake often looks fine from the driveway but has a broken seal at the crown or a bent mounting flange that lets water in. The only way to know is to get on the roof and look at the crown surface, then run a camera down the flue to check for seismic hairline cracks in the liner. That inspection is included on every visit. Call (980) 580-8641 to book one.
Because the original crack was never properly repaired. A crown that cracked in 1987 keeps moving with seasonal temperature changes and settling, which is why surface patching fails within a few seasons. The fix is to rebuild the crown with a proper slope and flexible sealant, not to smear more patch material over the old crack. We do this work in San Gabriel regularly, and the repair typically runs $450 to $900.
Stainless steel, mechanically fastened, sized to the actual flue tile. Galvanized corrodes too fast in San Gabriel’s coastal air and against older brick. Stainless from Olympia Chimney or Famco holds up, and a cap that’s mechanically anchored won’t lift in the wind the way a caulked-on unit can. We’ll measure the flue on site so the cap fits tight and stays put.
No, but you need an inspection before you light the first fire of the season if you haven’t had one in the last year or two. The risk in San Gabriel isn’t heavy creosote from frequent burning. It’s debris from Santa Ana winds, nesting from the months the fireplace sits idle, and undetected crown damage letting moisture into the flue. A Level 2 camera inspection catches all of that before it becomes a fire or carbon monoxide problem.
In most cases you can do the crown repair without replacing the cap, unless the cap itself is rusted, loose, or sized wrong. The real question is what the camera shows in the flue liner. If the crown has been leaking for years, the liner is often cracked and needs attention too. We’ll show you the camera footage and give you a written breakdown of what’s urgent, what can wait, and what each repair costs before you decide anything.
