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.

AfterTrusted Chimney Cap & Crown for Joliet Homeowners
A Joliet Chimney Cap & Crown repair typically costs between $285 and $1,850 depending on whether you need a simple cap replacement or full crown rebuild, and most jobs are completed in a single visit. Level Two Chimney Co. has inspected and serviced more than 38,000 chimneys since 2009, and we’ve documented every Joliet cap and crown job with before-and-after photos under Haven Standard Clause 4. If you’re seeing water stains on your fireplace ceiling, rusted firebox components, or pieces of concrete on your roof below the chimney, the crown is likely cracked and the cap may be missing or improperly fitted. Call us at (815) 620-5234 for a written estimate before any work begins.
Joliet’s freeze-thaw cycles are brutal on chimney crowns. The concrete absorbs rainwater through hairline cracks, expands when temperatures drop below 20°F, and spalls off in chunks by spring. We’ve replaced crowns in the Cathedral Area where the original construction was little more than a thin mortar wash, and we’ve installed multi-flue caps on historic homes near the Des Plaines River where standard sizes won’t fit. Our technicians are background-checked, uniformed, and licensed, and you’ll get a text when we’re on the way.
What Our Chimney Cap & Crown Service Includes
Cap Installation
Cap installation protects your flue from rain, animals, and debris while maintaining proper draft. In Joliet, we install caps on chimneys that have never had one, often in neighborhoods like Silver Cross and Wesmere where builders skipped this step to cut costs. We measure your flue precisely, source the correct cap from our home inventory through Haven’s buying network, and secure it with stainless steel screws, not the cheap tension bands that blow off in Will County windstorms. Every installation includes a camera scan of the flue interior and a photo of the completed cap from roof level.
Cap Replacement
Cap replacement becomes necessary when the existing cap is rusted through, improperly sized, or missing entirely. We see this constantly in Joliet after storms, especially on homes near the I-80 corridor where wind exposure is highest. Our technician removes the old cap, inspects the flue tile for damage the old cap may have concealed, and installs a replacement that matches your heating appliance’s BTU output and draft requirements. We document the condition we found and the cap we installed in your written record.
Crown Repair
Crown repair addresses cracks and deterioration in the concrete slab that seals the chimney top between the flue liner and the outer brick. A typical Joliet crown repair runs $485-$780 and takes 3-4 hours, including curing time for the polymer-modified cement we apply. We grind out cracks to solid substrate, apply a bonding agent, and finish with a slope that sheds water away from the flue. In the Hickory Creek area, we’ve saved homeowners thousands by repairing crowns that other companies insisted needed full replacement.
Crown Coating
Crown coating is a preventive treatment for crowns showing early surface deterioration but still structurally sound. We use HeatShield CrownCoat or similar flexible masonry sealers that bridge hairline cracks and stop water penetration. This service makes sense for Joliet homeowners whose crowns are 5-15 years old and showing minor spalling, especially on homes in Plainfield and Shorewood with similar construction eras. The coating extends service life 5-10 years and costs significantly less than rebuild. We photograph the crown condition before and after, and note the coating type in your permanent record.
Multi-Flue Cap
Multi-flue caps cover two or more flues with a single structure, common on homes with both a fireplace and a furnace or water heater venting through the same chimney. We measure the full chimney top, fabricate or source a cap with proper clearances, and secure it to the crown or masonry with through-bolts. In Joliet’s newer subdivisions like Grand Haven and Preston Heights, we’ve installed DuraFlex and Gelco multi-flue caps that accommodate side-by-side flues with different diameters. These caps prevent cross-drafting and keep one appliance from back-drafting into another.
Custom Cap
Custom caps are fabricated for chimneys with unusual dimensions, decorative shrouds, or heritage requirements. We’ve built custom copper caps for homes in the East Side Historic District and oversized galvanized caps for commercial properties near the Joliet Union Station. Our technician brings measurements and photos to our fabricator, and you receive a written quote before any metal is cut. Custom work takes 2-3 weeks from measurement to installation, and we store your template for future replacement.

Brands We Service for Chimney Cap & Crown
We install and service caps and crowns using materials from Copperfield, DuraFlex, HeatShield, and Gelco, sourced through Haven’s buying network to keep customer prices honest. Copperfield’s galvanized and stainless steel caps have been our standard for single-flue installations since 2012; we’ve fitted hundreds on Joliet homes and stock their most common sizes. DuraFlex’s multi-flue caps and liner systems are our go-to when we’re integrating cap replacement with liner repair or replacement, particularly on older Joliet homes with deteriorated clay flue tiles.
HeatShield’s CrownCoat and resurfacing products allow us to repair rather than replace crowns that other companies write off. We’ve applied HeatShield on more than 200 Joliet-area crowns, and the product’s flexibility through freeze-thaw cycles is proven in our 15-year local track record. Gelco’s premium stainless caps with lifetime warranties suit homeowners planning long-term occupancy, especially in the New Lenox Chimney Cap & Crown market and Homer Glen where we also work. Whether you have these brands or any other make, we can help.

AfterSigns You Need Chimney Cap & Crown Right Now
- Water stains or peeling wallpaper on the ceiling around your fireplace. This means water is entering through a cracked crown or missing cap and running down the flue interior. In Joliet, we see this most in spring after freeze-thaw damage has opened new cracks over winter. Left unaddressed, the water rusts the damper, deteriorates the smoke chamber, and can rot ceiling joists.
- Pieces of concrete or mortar on your roof or in your yard below the chimney. This is spalling, and it means your crown is actively disintegrating. The concrete surface has delaminated from freeze-thaw cycles, and the structural slab is next. We’ve collected handfuls of crown debris from gutters in the Rockdale area where homeowners didn’t realize the severity until we showed them roof-level photos.
- Rust stains or standing water in your firebox. A properly fitted cap keeps rain out of the flue. If you’re seeing rust on the damper or wet ash, the cap is missing, damaged, or incorrectly sized. This moisture also accelerates creosote buildup and can cause unpleasant odors when the fireplace isn’t in use.
- Animals or nesting debris in your fireplace. Squirrels, raccoons, and starlings enter uncapped flues readily, especially in Joliet’s wooded neighborhoods like Pilcher Park and along the I&M Canal. A cap with proper mesh screening prevents this. We’ve removed nests that blocked flues entirely, creating carbon monoxide hazards for the occupants.
- White efflorescence or green moss on your chimney exterior. These indicate chronic moisture saturation in the masonry, often from a crown that sheds water poorly or a cap that directs it onto the brick. The moisture breaks down mortar joints and leads to costly tuckpointing or rebuild. We diagnose the source with a camera inspection and address it at the crown level.
Our Chimney Cap & Crown Process - Step by Step
- 1
Schedule and confirm. Call (815) 620-5234 and speak with a live person, 24 hours a day. We book your appointment, send a confirmation with your technician’s name, and text when they’re en route. No voicemail, no web form black holes.
- 2
Roof-level inspection and camera scan. Your technician arrives in uniform with license information visible, sets a ladder, and photographs the crown and cap condition from above. They then run a chimney camera down the flue to document interior water damage, liner condition, and creosote class. You see the footage in real time if you’re present.
- 3
Written diagnosis and price. We explain what we found in plain terms, show you the photos, and deliver a written scope with a fixed price before any work begins. This is Haven Standard Clause 1: “Have it in writing.” If you brought a competitor’s written estimate, we’ll give you a free second opinion.
- 4
Cap or crown work with documentation. We complete the agreed work using materials from our procured inventory, photograph every stage, and note product serial numbers or batch codes when applicable. Crown repairs receive proper cure time before we consider the job complete.
- 5
Final documentation and warranty. You receive a written completion report with photos, a description of work performed, materials used, and the 365-Day Done Right Promise. Your record joins the 38,000+ documented jobs in our archive, searchable by address for future reference or real estate transactions.
How Much Does Chimney Cap & Crown Cost in Joliet?
Our Chimney Cap & Crown cost guide shows a typical replacement in Joliet runs $285-$550 depending on flue size, cap material (galvanized, stainless, or copper), and roof access difficulty. Crown repair typically costs $485-$780 for crack remediation and resurfacing. Full crown rebuild, where we pour a new concrete slab with proper reinforcement and overhang, ranges $1,200-$1,850. Custom caps start around $650 for galvanized and exceed $2,000 for ornate copper work on historic chimneys.
Several factors move the price within these ranges. Roof pitch and height affect labor time and safety equipment needs; we don’t surcharge for two-story homes, but three-story or steep-pitch jobs require additional setup. Crown condition determines whether repair, coating, or rebuild is appropriate, and we make that call based on what the camera and photos show, not a guess from the driveway. Material choice matters: a Gelco stainless cap with lifetime warranty costs more upfront than galvanized with a 5-year warranty, but the math favors stainless for most Joliet homeowners planning to stay 10+ years.
To avoid overpaying, get any recommendation in writing with photo evidence. We’ve reviewed competitor quotes in Joliet that specified “crown rebuild” for damage that our camera revealed was superficial cracking addressable with coating. Our free estimate includes the camera inspection and photo documentation at no charge, so you have independent evidence of what you actually need. The price we write is the price you pay; no trip charges, no material upcharges, no surprises.

Frequently Asked Questions - Chimney Cap & Crown in Joliet
The crown is the concrete slab that tops your chimney and sheds water away from the flue; the cap is the metal cover that sits above the flue opening to block rain, animals, and debris while allowing smoke to exit. You need both because the crown protects the masonry structure and the cap protects the flue interior; a good crown with no cap still lets water directly into your fireplace system, and a cap on a cracked crown won’t stop water from destroying the chimney body. In Joliet’s climate, both components typically need attention every 15-25 years.
Most cap installations and replacements take 1-2 hours; crown repairs take 3-4 hours including cure time; full crown rebuilds require 4-6 hours and may need a return visit for final sealing. We schedule enough time that your technician isn’t rushing to the next job, and we don’t leave until the work is documented and you’ve received your written completion report.
