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 Schaumburg
A chimney cap and crown repair in Schaumburg typically runs $425-$1,850 depending on whether we’re fabricating a custom multi-flue cap for an aging prefab unit or recoating a spalled chase cover. Most homeowners in Weathersfield, Plum Grove, and Saxon Park book the work because water is already getting past a cracked crown or a rusted stock cap. If you’re seeing water stains near the firebox or you’ve spotted rust streaking down the chase, call (980) 580-8641 and we’ll get a camera down the flue to show you exactly what’s failing before anyone quotes a dollar.
Our crews drive the Schaumburg grid weekly. We know the split-levels off Wise Road, the colonials near Fabbrini Park, the ranch homes off Springinsguth. More important, we know what 40-year-old prefab fireplaces look like when their caps and crowns finally give out. This page tells you what we find, what it costs to fix, and why the freeze-thaw patterns here make waiting expensive.
Why Emberly Chimney Cleaners Is Schaumburg’s Preferred Chimney Cap & Crown Company
Schaumburg homeowners call us because the written quote includes camera photos of the exact cap, crown, and flue liner condition. Not a flashlight guess. Clause 4 of the Haven Standard requires a documented photo record on every job, and that’s been our default since 2009, long before insurers started asking for it. That record matters in this suburb: most of these prefab systems are decades past their rated service life, and the homeowner deserves to see the crack, the rust line, or the spalled mortar with their own eyes before approving a repair.
We’re not the cheapest Chimney Cap & Crown outfit in the northwest suburbs, and we don’t try to be. We quote a written price before any work starts, with a written scope and a written warranty under Haven Standard Clause 1. No tech standing in your living room doing mental math. No “we’ll see what we find.” You get the number in writing, and you decide.
Every Schaumburg job gets a background-checked, uniformed technician with a license number on file. Corrine Halstead runs the operation, and she has built the Schaumburg route around one principle: show the evidence, name the price, document the result. If it’s not done right, the 365-Day Done Right Promise means we come back and make it right. That’s not a sales line. It’s stamped on every job under the Haven Standard.
Our Chimney Cap & Crown Services in Schaumburg
Custom Cap Fabrication
Most Schaumburg homes with 1970s or 1980s Heatilator, Superior, or Majestic zero-clearance units have flue configurations that no off-the-shelf cap fits anymore. The original caps rusted out years ago, and replacements simply don’t exist in standard sizes. We fabricate custom Copperfield caps in-house, sized to the actual flue liner outside diameters, with baffles tuned to the prevailing northwest wind exposure common on Schaumburg’s flat, open lots. You get a cap that actually seals the flue, not one that wobbles on an adapter kit.
Multi-Flue Cap Installation
Many of the original prefab installations in Schaumburg ran two flue liners side by side through a single chase, one for the fireplace and one for a furnace or water heater. When the original shared cap rusts through, both liners sit open to snow, rain, and squirrels. We build and install custom multi-flue caps with separate screened openings for each liner, sized on-site, so both appliances vent correctly. This is the single most common Chimney Cap & Crown in Schaumburg job we see in Weathersfield and Plum Grove.
Crown Repair on Prefab Chase Covers
The mortar crown on a prefab chase cover catches every freeze-thaw cycle Schaumburg delivers. Water seeps into hairline cracks, freezes, expands, and pops the surface apart. A crown that looked fine in October can be spalled and crumbling by March. We grind back the damaged mortar, repair the crown profile so water sheets away from the flue liners, and recoat the surface. On chase covers that are rusted through, we replace the metal pan as well as the crown.
Crown Coating with Gelco
Gelco crown sealer is a flexible, waterproof membrane designed specifically for chimney crowns. It bridges the microscopic cracks that let water in during Schaumburg’s daily thaw cycles, and it stays flexible when the temperature swings. We recommend Gelco on every chase cover crown we touch in this area, even when the crown looks intact, because the freeze-thaw cycling here is severe enough that hairline cracks are almost always present by the time a home is 30 years old.

We stock common parts locally so a straightforward cap swap on a Weathersfield split-level doesn’t turn into a two-week wait.
Common Chimney Cap & Crown Problems We See in Schaumburg Homes
- Freeze-thaw spalling on mortar crowns. Schaumburg crosses the freezing point dozens of times each heating season. Water works into microscopic crown cracks, freezes, expands, and breaks the surface apart. By the time you see chunks of mortar on the ground, the crown has already been failing for at least one full winter.
- Rusted-out stock caps on 1970s-80s prefab units. The original caps on Heatilator and Superior zero-clearance systems were galvanized steel with a 20-year service life. Most have been rusting for decades, leaving flue liners open to snow, rain, and animal entry between annual inspections.
- Downdraft issues on flat, exposed subdivisions. Schaumburg’s open grid, light tree cover, and prevailing northwest winds create negative-pressure conditions that push smoke back down the flue. A properly baffled custom cap redirects airflow and stops the backdraft, especially on corner lots and homes with no windbreak.
- Cracked refractory panels found during cap and crown calls. When we pull a rusted cap to replace it, we often find the firebrick panels inside the original prefab unit cracked completely through. The unit was rated for 20-30 years. At 40-50 years old, the cap failure is usually the first visible sign of a system that needs more than a cap swap.

FAQs - Chimney Cap & Crown in Schaumburg
Because the original Heatilator, Superior, and Majestic zero-clearance systems installed during Schaumburg’s 1960s-1980s buildout used flue sizes and multi-liner configurations that manufacturers stopped producing decades ago. Off-the-shelf caps don’t fit. We fabricate a custom Copperfield cap to the actual outside diameter of the existing flue liners, with proper screen and baffle sizing for the unit’s draft requirements. Call (980) 580-8641 and we’ll measure and quote it in writing.
Schaumburg’s temperature crosses 32°F dozens of times per heating season. Each crossing is a cycle: water fills a microcrack, freezes, expands roughly 9%, and wedges the crack wider before thawing. Over a single winter that’s hundreds of expansion events working on the mortar crown. The crowns on prefab chase covers are thinner than full masonry crowns, so they fail faster here. Gelco coating stops water from entering those cracks in the first place.
Often yes. Schaumburg’s open grid and lack of tree cover mean northwest winds hit chimneys with little obstruction. A baffled custom cap redirects that airflow around the flue opening instead of letting it push smoke down into the firebox. On a split-level in Weathersfield with a persistent downdraft, the right baffle cap can eliminate the backdraft entirely. We’ll know after we look at the flue height, roof pitch, and prevailing exposure.
Frequently, yes. The cap is usually the first thing to visibly fail, but once we camera-scan the flue, we often find cracked refractory panels, a corroded damper assembly, or a rusted firebox behind it. The unit was rated for 20-30 years, and many Schaumburg ranches have units that are 45 years old. We’ll show you the photos and tell you plainly what can wait and what cannot. You’ll have the evidence before you spend a dollar.
Because by the time spalling shows on the surface, the crown has been absorbing water for at least a season. The freeze-thaw cycling in Schaumburg is aggressive enough that hairline cracks are almost certainly present even when the crown looks solid from the ground. Gelco seals those cracks before they widen, and the flexible membrane moves with the crown through every freeze cycle. It’s the single most cost-effective preventative measure for a Schaumburg prefab chase.
