Downers Grove sits on clay-heavy soils that shift through freeze-thaw cycles, and that movement cracks chimney crowns faster than in areas with sandier ground. We’ve replaced crowns on homes from Fisher to Lester to Highland neighborhoods where the original concrete crown lasted fifteen years, then failed all at once after a hard winter. Our technicians are background-checked, uniformed, and licensed; you’ll get a text when yours is on the way, and a photo record of every finding before we quote any repair.

What Our Chimney Cap & Crown Service Includes

Cap Installation

A chimney cap is a metal cover that sits over your flue opening to block rain, animals, and debris while letting smoke escape. In Downers Grove, we install caps on unprotected flues year-round, but we see the most urgent calls after spring storms when squirrels nest or heavy rain pours straight down an open flue. Emberly Chimney Cleaners Downers Grove measures your flue precisely, sources caps through our Haven buying network from Copperfield and Gelco, and stamps every installation with our written warranty under Clause 1 of the Haven Standard: your price and scope in writing before we start.

Cap Replacement

Cap replacement becomes necessary when the existing cap rusts through, blows off in wind, or no longer fits after flue liner work. We replace dozens of caps each season in Downers Grove, often finding the original was a generic big-box size that left gaps for water intrusion. Our replacement process includes a Level 2 camera inspection of the flue beneath the cap, because a damaged cap often hides spalling brick or deteriorated mortar that needs addressing first. You’ll receive photos of the flue condition, a written price for the cap replacement, and a second written price if additional repairs are warranted.

Crown Repair

The crown is the concrete slab that seals the top of your chimney between the flue tiles and the brick edge; when it cracks, water seeps directly into the chimney structure. Crown repair in Downers Grove typically addresses cracks under 1/4 inch using a specialized flexible crown coating, applied after wire-brushing loose material and priming the surface. We document the crack pattern with photos before and after, because crown damage often indicates deeper settlement issues in this clay-soil region. If our camera inspection reveals the crack extends below the crown surface, we’ll show you exactly what we found and quote crown rebuilding separately.

Crown Coating

Crown coating is a preventive treatment for crowns showing early hairline cracking but still structurally sound, essentially a waterproof membrane that bridges small gaps before they widen. In Downers Grove, we recommend crown coating for concrete crowns between five and twelve years old, especially on homes in the older neighborhoods south of 63rd Street where original construction predates modern crown slope standards. We use HeatShield and DuraFlex coating systems procured through our Haven buying network, applied in temperatures above 40 degrees with a 48-hour cure time. The coating carries its own material warranty, and our 365-Day Done Right Promise covers application integrity.

Multi-Flue Cap

A multi-flue cap spans two or more flue openings with a single cover, common in Downers Grove homes with both a fireplace flue and a furnace flue rising through the same chimney structure. Multi-flue caps must be sized to clear all flue terminals by proper height, with screening that won’t clog from combined appliance exhaust. We fabricate and install multi-flue caps from measured drawings, not guesswork, because an undersized cap creates drafting problems and an oversized one catches wind. Your written estimate includes the cap specification sheet, material gauge, and mesh size.

Custom Cap

Custom caps solve problems standard sizes cannot: oversized flues, unusual chimney shapes, historic preservation requirements, or aesthetic matching on prominent homes. We’ve built custom caps for Downers Grove properties in the Longfellow and Randall Park historic areas where the village’s architectural review committee requires specific finishes. Our custom work uses copper, stainless steel, or powder-coated galvanized steel from Copperfield and Gelco, with shop drawings submitted for your approval before fabrication. Every custom cap includes the same written price guarantee and photo documentation as our standard installations.

Brands We Service for Chimney Cap & Crown

We source chimney cap and crown materials through the Haven buying network specifically to keep customer prices honest, with direct relationships established since 2009. Copperfield supplies our stainless steel and copper standard caps; we’ve installed hundreds of their units across Downers Grove and keep common sizes in regional inventory for faster turnaround. DuraFlex provides our flexible liner systems and crown coating resins, materials we’ve used on chimney rebuilds where the original crown failed due to liner deterioration that went undiagnosed. Their coating system bonds to concrete at the molecular level, which matters on crowns with micro-porosity from years of freeze-thaw.

HeatShield manufactures the cerfractory flue sealant and crown repair compounds we use when structural integrity is compromised but full rebuild isn’t yet warranted; we’ve completed more than 400 HeatShield applications since adding the product line in 2014. Gelco covers our multi-flue and custom cap fabrication, with a Midwest distribution point that lets us turn custom orders in ten business days rather than four weeks. Whether you have Copperfield, DuraFlex, HeatShield, Gelco, or any other make on your chimney, we can inspect it, repair it, or replace it with documentation at every step.

Signs You Need Chimney Cap & Crown Right Now

• Water stains on your ceiling near the chimney breast. These stains mean water is entering through the crown or flue opening, running down the interior chimney structure, and exiting where the chimney passes through your roof framing. In Downers Grove, we trace these stains to failed crowns in roughly sixty percent of cases and to missing or damaged caps in most of the rest. Left unaddressed, the water rots roof decking and rusts furnace flue liners.
• Visible cracks in the concrete crown surface. Hairline cracks widen each freeze-thaw cycle as water enters, expands, and wedges the gap further open. We photograph crown cracks during every Level 2 inspection and measure them against a reference scale, because a crack that reads 1/8 inch in October can be 3/8 inch and leaking by March. Crown coating works on smaller cracks; larger ones require rebuild before the underlying brick suffers spalling damage.
• Rust flakes or debris falling into your fireplace. If you sweep rust particles from your firebox or find them on the damper, your cap is either missing, damaged, or incorrectly sized for a metal flue liner. The rust is your flue liner corroding from exterior moisture exposure, and that liner protects your home from chimney fires and carbon monoxide intrusion. We replace caps and assess liner condition with camera inspection on the same visit.
• Animal sounds or nesting materials in the flue. Squirrels, raccoons, and starlings enter open flues in Downers Grove year-round, but March through May brings the most calls as breeding season peaks. A proper cap with animal-proof mesh prevents entry without restricting draft; we’ve removed nests and installed preventive caps on homes from Maple Avenue to Belmont Road. The camera inspection after animal eviction often reveals claw damage to clay flue tiles that needs separate repair.
• White efflorescence staining on exterior brick below the crown. That chalky white residue is mineral salts left when water evaporates from saturated masonry, and it means your crown is no longer shedding water properly. Efflorescence in Downers Grove appears most prominently on north-facing chimney exposures where drying is slowest. The staining itself is cosmetic, but the water movement behind it destroys mortar joints from the inside out.

Our Chimney Cap & Crown Process - Step by Step

1. 1
   Schedule and confirm. Call (331) 253-4980 and speak with a live person, any hour. We’ll ask about your chimney’s age, symptoms you’ve noticed, and whether you’ve had prior cap or crown work. We assign a named technician, run a background confirmation, and text you when they’re en route with an estimated arrival window.
2. 2
   Level 2 camera inspection. Your technician arrives uniformed with license identification visible. We set up containment, run a video camera the full length of the flue, and inspect the crown surface, cap condition, and exterior brickwork. This inspection follows NFPA 211 Level 2 standards and produces a documented photo record required under Clause 4 of the Haven Standard.
3. 3
   Written findings and pricing. We show you the camera footage and photos on a tablet, name what we found in plain terms, and deliver a written price for each recommended repair. If the crown is cracked but the flue is sound, you’ll see two prices: crown repair and cap replacement as separate line items. Nothing is combined or hidden. Clause 1 of the Haven Standard requires this written price before any work begins.
4. 4
   Execution with documentation. Once you approve the scope, we complete the work in a single visit for most cap replacements and crown coatings, or schedule return visits for custom fabrication or full crown rebuilds. We photograph each stage: crown preparation, coating application, cap installation with proper clearances. You receive digital copies of all photos with your invoice.
5. 5
   Written warranty and archive. Every cap and crown job concludes with a written warranty document and a 365-Day Done Right Promise stamped on your record. Your inspection photos, written scope, and warranty are archived in our system for future reference, so if you sell your Downers Grove home or need warranty service, the documentation is retrievable by address.
