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.
Trusted Chimney Cap & Crown for Naperville Homeowners
A properly fitted chimney cap and intact crown keep water, animals, and debris out of your flue system. In Naperville, where freeze-thaw cycles from November through March crack concrete crowns faster than in milder climates, we replace or repair more crowns between February and April than any other season. Call (331) 265-1700 for a free estimate with written pricing before any work begins.
We’ve inspected over 38,000 chimneys since 2009, and the pattern in Naperville is consistent: homes built between 1985 and 2010, especially in neighborhoods like Cress Creek, Hobson West, and East Highlands, often have original concrete crowns that have never been sealed. Water gets in, freezes, and the crown spalls. By the time a homeowner notices a leak, the damage has usually reached the flue liner. Our NFPA 211 Level 2 inspection with camera documentation, included on every visit under Haven Standard Clause 4, shows you exactly what you’re dealing with before we quote a price.
Corrine Halstead and our team at Level Two Chimney Naperville don’t do flashlight inspections. We lower a camera, record what we find, and hand you a written scope with a written price. No surprises, no upsell after the tech is in your home. That’s Haven Standard Clause 1: have it in writing before anyone starts.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is a metal cover that sits over your flue opening, blocking rain, snow, squirrels, and airborne debris while letting smoke and combustion gases escape. You need one if your flue terminates without protection, which is common in Naperville’s ranch and split-level stock from the 1970s through 1990s. At Level Two Chimney Naperville, we measure your flue precisely, source caps through our Haven buying network from Gelco and Famco, and install with stainless steel fasteners rated for our local wind exposure. Every installation includes a photo record of the fit and finish, stamped under Clause 4.

Cap Replacement
Existing caps corrode, blow off in high winds, or get damaged by falling branches, particularly after the severe weather Downers Grove and Naperville see each spring. We remove the failed unit, inspect the flue tile beneath for hidden damage the old cap may have concealed, and install a replacement sized to your exact flue count and dimension. We stock common sizes for immediate replacement and can source custom profiles within 48 hours for older or non-standard constructions.

Crown Repair
The crown is the concrete slab that tops your masonry chimney, sloped to shed water away from the flue. Cracks, spalling (surface flaking), or deterioration at the edges let water penetrate the brickwork below. We chase cracks to sound concrete, apply a bonding agent, and pack with high-strength repair mortar formulated for chimney exposure. For crowns with minor cracking but sound structural integrity, this restores waterproofing without full replacement. We photograph the damage before and after, and the repair carries our 365-Day Done Right Promise.

Crown Coating
Crown coating is a brush-applied elastomeric sealant that bridges hairline cracks and restores surface waterproofing on crowns that are structurally sound but weathered. It’s not a substitute for repair if the crown is crumbling, but it’s the right call for preventive maintenance on crowns showing early age. We apply two coats after cleaning the surface, with full cure time respected before exposure. In Wheaton and Naperville’s climate, we recommend re-evaluation every three to five years. The coating material is procured through our Haven network to keep pricing honest.

Multi-Flue Cap
Multi-flue caps cover two or more flue terminals with a single structural unit, common in homes with both a fireplace flue and a furnace or water heater venting through the same chimney. These require precise measurement of flue spacing and height differential, plus adequate clearance for each appliance’s draft. We fabricate and install multi-flue caps from Olympia Chimney and Copperfield stock, with spark arrestor mesh where required by local ordinance. The installation is documented with photos showing clearances and fastener placement.

Custom Cap
Some Naperville homes, particularly the custom builds in Ashbury and Tall Grass, have non-standard flue configurations, decorative chimney pots, or heritage masonry that demands a fabricated solution. We measure on-site, specify material and finish, and source through our buying network for production and installation. Custom work receives the same written price, written scope, and written warranty as standard items, with progress photos at fabrication and final install under Haven Standard Clause 4.

Brands We Service for Chimney Cap & Crown

We work with DuraFlex components for their stainless steel flex liner and cap integration systems, particularly where a new cap must mate with a relined flue. Their collar adapters and termination caps fit precisely, and we’ve installed hundreds in DuPage and Will County homes where the original clay tile liner has been replaced. We stock common DuraFlex termination hardware and can source same-week for less common diameters.
HeatShield cerfractory coating systems come into play when crown damage has allowed moisture to degrade the flue liner beneath. We don’t just cap over the problem. If the camera scan shows liner deterioration, we quote HeatShield resurfacing or relining as part of the scope, with the cap or crown work sequenced to protect the repair. Gelco caps are our standard for single-flue galvanized and stainless installations, their mounting systems are field-proven in Naperville’s wind conditions, and we keep their most common sizes on the truck. Whether you have Gelco, Olympia Chimney, or any other make, we can service, replace, or upgrade it. Bring us a competitor’s written estimate for any of this work and we’ll give you a free second opinion.
Before
AfterSigns You Need Chimney Cap & Crown Right Now
- Water stains on the ceiling near your fireplace. This means moisture is entering above the firebox, traveling down the flue or through the crown, and finding its way to your interior finish. In Naperville, we see this most often after the first hard freeze when an existing crack opens wider. The longer it runs, the more likely you’ll need drywall repair and masonry repointing in addition to crown work.
- White efflorescence staining on exterior brick below the crown. That powdery white deposit is mineral salts left behind as water evaporates through the masonry. It’s evidence of chronic water intrusion from a failed crown or missing cap. The brick is getting wet repeatedly, and each freeze-thaw cycle expands the damage.
- Chunks of concrete visible on the roof or in the firebox. Spalling crown material doesn’t stay put. If you’re finding pieces, the crown has lost structural integrity and water is penetrating the mass. This is past the point where coating helps; you need repair or replacement.
- Animal sounds or debris in the flue. Squirrels, raccoons, and starlings enter open flues readily, especially in Naperville’s mature-tree neighborhoods like Riverwoods and White Eagle. A missing or damaged cap is the entry point. Nesting material blocks draft and creates a fire hazard; animal carcasses compound the problem with odor and insect attraction.
- Rust on the fireplace damper or firebox. Rust means water is getting in and not draining out. The source is almost always a failed crown, missing cap, or deteriorated flashing at the chimney base. Left unaddressed, the damper seizes, the firebox metal thins, and replacement costs multiply.
Our Chimney Cap & Crown Process - Step by Step

- 1
Schedule and confirm. Call (331) 265-1700 and you’ll reach a live person, not a voicemail tree. We confirm your address in Naperville or a surrounding community, note any access concerns like a steep roof or locked gate, and assign a named, background-checked technician. You get a text when they’re en route.
- 2
NFPA 211 Level 2 inspection with camera documentation. We set up, protect your floors, and run a camera down the flue to assess liner condition, creosote accumulation, and any obstruction. We photograph the crown from the roof, the cap from multiple angles, and the flue terminal. This is Clause 4 of the Haven Standard, and we’ve done it on every job since 2009.
- 3
Written diagnosis and price. We show you the photos, explain what we found in plain terms, and hand you a written scope with line-item pricing. No work starts until you approve in writing. This is Haven Standard Clause 1. If the camera shows liner damage or other issues beyond the cap or crown, we quote those separately and flag what can wait versus what can’t.
- 4
Execution with photo record. Approved work proceeds with the materials specified: DuraFlex, Gelco, Olympia Chimney, or other components sourced through our Haven buying network. We photograph key stages, final fit, and clearances. For crown repairs, we document the prepared surface, applied material, and finished slope.
- 5
Documentation and warranty. You receive a completed job record with photos, a written warranty, and our 365-Day Done Right Promise. If anything isn’t right, we make it right. The record goes into your file for future reference and is available if your insurer or home buyer requests chimney documentation.
How Much Does Chimney Cap & Crown Cost in Naperville?
Chimney cap and crown work in Naperville typically runs $180 for a basic galvanized cap installation up to $1,800 for full crown replacement with custom forming and weatherproofing. Most homeowners we serve in neighborhoods like Springbrook, Maplebrook, and Naper Carriage Hill fall in the $340-$890 range for cap replacement with minor crown sealing or spot repair.
| Service | Typical Range in Naperville | What Drives the Price |
|---|---|---|
| Standard cap installation (single flue, stainless steel) | $180-$340 | Flue diameter, cap material grade, roof access difficulty |
| Cap replacement with removal of damaged unit | $260-$480 | Condition of existing fasteners, hidden flue tile damage, multi-flue configuration |
| Crown coating (preventive, sound substrate) | $340-$580 | Crown square footage, number of coats, accessibility |
| Crown repair (crack chasing, partial rebuild) | $580-$1,200 | Extent of spalling, need for forming, liner interface work |
| Full crown replacement | $1,200-$1,800 | Chimney dimensions, forming complexity, flue count, finish requirements |
| Custom cap (fabricated, non-standard) | $480-$1,400 | Material, finish, complexity of mounting, production lead time |
What affects your specific price: roof pitch and height (we work safely on two-story and steep roofs, but equipment needs vary), flue count and spacing, and whether the inspection reveals secondary damage like liner deterioration or flashing failure. We quote everything we find, but we also tell you plainly what can wait. A crown with minor cracking and no water intrusion doesn’t need replacement this season. We’ll say so, document it, and note re-check timing.
How to avoid overpaying: get a second opinion on any estimate over $1,000, especially if it was delivered verbally after the tech was already in your home. We provide free second opinions on any competitor’s written estimate. What’s included in our free estimate: the NFPA 211 Level 2 inspection, camera documentation, written scope, and written price. No charge, no obligation to book.

Frequently Asked Questions - Chimney Cap & Crown in Naperville

Chimney cap and crown service covers the installation, replacement, repair, and sealing of the components that protect the top of your chimney. The cap is a metal cover over the flue opening; the crown is the concrete slab that sheds water away from the flue and masonry. Together they prevent water damage, animal intrusion, and debris accumulation that block draft and create fire hazards.
Most cap installations and replacements are completed in one to two hours. Crown coating takes two to three hours including surface prep and cure setup. Crown repair or replacement typically requires three to five hours and may need a return visit if forming and pour sequencing demands it. We give you a time estimate in writing with your price quote. Call (331) 265-1700 for scheduling.
Typical costs range from $180 for a basic cap installation to $1,800 for full crown replacement, with most homeowners paying between $340 and $890 for cap replacement with minor crown maintenance.
