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.

AfterFast, Reliable Chimney Cap & Crown Across Ontario
Chimney cap and crown work in Ontario usually means one of three things: a corroded galvanized cap on a 1980s or 1990s tract home prefab fireplace, a spalled metal termination crown, or a cap that’s been torn apart by Santa Ana winds off the Cajon Pass. A standard cap replacement in Ontario runs $165-$320, and a crown coating job typically lands between $275-$475. We serve Ontario homes directly from our Inland Empire office, with background-checked techs who know exactly what a zero-clearance fireplace flue looks like after thirty years of wind-driven grit. Call (980) 580-8641 and we’ll give you a written price before anyone picks up a ladder.
Why Emberly Chimney Cleaners Is Ontario’s Preferred Chimney Cap & Crown Company
Ontario homeowners call us because our inspection standard matches what the city’s housing stock actually needs. Most of Ontario’s residential neighborhoods were built out between 1980 and 2000, and the fireplaces in those homes are factory-built metal units with round flues and thin termination caps. That’s our specialty. We’ve inspected and cleaned more than 38,000 chimneys since 2009, and every single one got a camera scan and a documented photo record. Clause 4 of the Haven Standard requires it, and we’ve done it that way since the day we opened.
Our crews arrive at Ontario homes in uniform, with a named tech and a text before we’re on the way. We answer our phone with a live person, 24 hours a day, seven days a week. No voicemail trees. And every job, whether it’s a simple cap swap near Ontario Mills or a full crown replacement off Euclid Avenue, comes with a written scope, a written price, and a written warranty before work starts. That’s Clause 1 of the Haven Standard: have it in writing.
What Ontario customers tell us they want is the price on the page and evidence in hand. We give both. A family in the Creekside neighborhood got a full replacement quote with photos of their rusted-out Famco cap before any tool came off the truck. That’s how we work everywhere in Ontario, from the historic downtown blocks to the newer subdivisions north of the 10.
Our Chimney Cap & Crown Services in Ontario
Cap Replacement
Cap replacement in Ontario is the most common call we get, and it’s rarely about aesthetics. The galvanized caps put on 1980s and 1990s tract home fireplaces are thin, and after 30 years of Santa Ana-driven sand and palm fronds off the Cajon Pass corridor, they rust through. A typical cap replacement in Ontario runs $165-$320, including the stainless steel replacement cap and removal of the old one. We favor stainless steel because Ontario’s wind and idle-ember conditions are too punishing for a repeat galvanized unit.
Crown Coating
Most Ontario prefab fireplaces don’t have a true masonry crown. They have a metal termination cap that gets called a crown, and it’s the first thing to fail. Crown coating with a product like Gelco CrownCoat seals hairline cracks and prevents water from running down the inner liner. In Ontario, expect to pay $275-$475 for a crown coating job, which includes surface prep and a full photo record when it’s done. A cracked crown left alone through one winter of Santa Ana rain events turns into a corroded flue liner within two or three seasons.
Custom Cap
Some Ontario tract homes were built with non-standard flue spacing on multi-flue setups, especially where a fireplace and a water heater share a chase. A custom cap in Ontario runs $375-$700, depending on flue count and dimensions. We measure on site, then fabricate or order to spec. If your existing cap doesn’t sit flush because the original was a builder-grade generic, this is the fix.
Cap Installation
If you’re having a fireplace installed in a new addition or replacing a missing cap, our Ontario cap installation service covers the whole job: measuring, fitting, sealing, and documenting. Installation runs $140-$290 for a standard single-flue cap. We also do multi-flue caps for larger homes in Ontario’s newer developments, where you might have two zero-clearance flues side by side.

BeforeAfterTrusted Brands We Service in Ontario
We work with hardware from Gelco, Famco, and Copperfield because those brands hold up to Ontario’s specific conditions better than most. Gelco’s CrownCoat product is our standard for crown sealing on metal termination units. Famco stainless caps are what we recommend for homes near the Ontario airport corridor and the open stretches along Archibald Avenue where wind load is highest. Copperfield does custom multi-flue work we’ve used on larger Ontario properties. We keep a running stock of common sizes for Ontario homes, which means most cap replacements go from inspection to done in a single visit.
Common Chimney Cap & Crown Problems We See in Ontario Homes
- Santa Ana wind damage. Ontario sits in the path of strong winds coming through the Cajon Pass corridor. Those gusts drive palm fronds and coarse sand directly into uncapped or weakly capped flues, abrading thin galvanized mesh until it tears. Once the mesh tears, debris gets past the spark arrestor and lodges against the flue wall.
- Prefab fireplace cap corrosion. The 1980s and 1990s tract homes that make up much of Ontario’s housing stock used factory-built zero-clearance fireplaces with galvanized inner liners. A damaged cap admits rain, and that rain corrodes the liner from the inside. What starts as a $200 cap replacement becomes a $1,500+ liner job if you wait.
- Nesting during SCAQMD no-burn periods. Ontario faces mandatory no-burn days throughout winter under South Coast Air Basin particulate rules. Those long idle periods turn flues into sheltered nesting sites, especially on multi-flue caps where the gap between flues stays dry and wind-protected. We regularly pull bird nests off cap undersides in Ontario homes that haven’t burned in months.
- Warped metal termination crowns. Zero-clearance fireplaces don’t have masonry crowns. The metal termination cap expands and contracts with heat, and after years of Ontario’s temperature swings plus wind-driven grit, it warps and cracks at the seams. Rain gets in, runs down the flue, and rusts the firebox components.

FAQs - Chimney Cap & Crown in Ontario
No. No-burn days reduce usage, but they don’t reduce exposure. A capped but idle flue in Ontario is still getting hit by Santa Ana wind, rain, and nesting birds. In fact, the long idle periods make nesting more likely, because birds find a sheltered, undisturbed spot on top of your cap or between flues on a multi-flue setup. If anything, no-burn days mean you should inspect more carefully, since problems accumulate without the regular burning that would otherwise give you smoke signals. Call (980) 580-8641 and we’ll camera-scan the flue and send you photos before recommending anything.
They fail because they were builder-grade galvanized steel, not stainless, and they were installed on zero-clearance units that were never meant to last this long. Ontario’s 30-to-40-year-old tract homes are full of prefab fireplaces that have outlived their rated service life by a decade or more. Add wind-driven grit from the Cajon Pass and you get abrasion that wears through thin galvanized mesh in a few seasons. Once the mesh tears, the cap’s done. Stainless replacement is the only fix that holds up.
It doesn’t behave like a masonry crown at all. On a prefab unit, the “crown” is really the metal termination cap, and it warps and cracks from repeated heating-and-cooling cycles plus wind load. Ontario’s temperature swings in winter, combined with dry Santa Ana events in fall, accelerate the cracking. Once cracked, rain runs down the inner liner and corrodes the galvanized flue, which is a more expensive repair than the crown coating would have been. Crown coating with Gelco CrownCoat seals those hairline cracks and stops water intrusion before it becomes a liner job.
Yes. We do it regularly in Ontario, especially on homes where the original builder used odd spacing between two flues or between a fireplace flue and a water heater flue. Custom caps run $375-$700 depending on the flue count and the exact spacing we measure on site. We fabricate or order to spec and install with a written warranty. The old cap comes off, the new one goes on, and you get photos of the whole thing.
Every year, before the first SCAQMD burn-permitted evening of winter. That’s the smart interval for Ontario because your cap is taking wind abuse year-round and sitting idle during no-burn periods, when birds are most likely to nest. We do an NFPA 211 Level 2 inspection with a camera down the flue and a full photo record on every visit. You walk away with evidence, not a sales pitch. If the cap’s sound, we’ll tell you plainly and recommend the next inspection window. Call (980) 580-8641 to book, and our team serving Ontario will get you scheduled.
