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.

AfterCopperfield Crown Repair: The Fort Worth Owner’s Guide
Copperfield crown repair in Fort Worth typically runs $340-$780 installed, depending on whether we’re sealing hairline cracks or rebuilding the full crown structure. We stock Copperfield-compatible crown sealants, flashing kits, and pre-formed concrete crowns on our Fort Worth trucks, and most repairs are completed in a single visit. You’ll get a written price before we start, plus photos of the damage and the finished work under Clause 4 of the Haven Standard.
Most Fort Worth homeowners discover crown trouble during a routine sweep or when water starts showing up inside the firebox after a hard rain. The crown sits at the very top of your chimney, sloped to shed water away from the flue. When it cracks or the sealant fails, water runs straight down into the masonry joints and liner system. In neighborhoods like River Oaks or the Cultural District, where freeze-thaw cycles hit harder than people expect, we’ve seen crowns deteriorate inside of eight years.
Which Copperfield Models This Applies To
Copperfield chimney supply crowns break down into three main product families, and matching the right repair approach matters.
- Copperfield Pre-Cast Concrete Crowns: These ship in standard sizes from 24″ x 24″ up to 48″ x 48″ with a built-in drip edge. The model number is stamped on the underside lip. If yours is spalling or the drip edge has cracked off, we measure the existing footprint and source a replacement through Haven’s buying network, usually from the same batch run.
- Copperfield CrownSeal Flexible Sealant: This is the gray elastomeric coating applied over existing concrete crowns with hairline cracking. It’s rated for 400% elongation and comes in 1-gallon and 5-gallon pails. The gotcha: CrownSeal bonds poorly to surfaces previously treated with silicone-based sealers. We check for that contamination with a simple solvent wipe test before quoting.
- Copperfield Flashing Kits (Model CF-FK series):strong> These include the counter-flashing and step flashing that integrate with the crown edge. If your leak is at the crown-to-flashing junction rather than the crown itself, the CF-FK-8 or CF-FK-10 typically fits residential chimney footprints in Fort Worth’s 1970s-2000s housing stock.
We carry both OEM Copperfield materials and equivalent-grade alternatives from Gelco and Olympia Chimney, sourced through Haven’s buying network to keep pricing honest. For Heritage-listed homes near the Stockyards or TCU area where appearance matters, we match the original crown profile rather than defaulting to whatever’s in the warehouse.

Signs Your Copperfield Crown Repair Is Failing
- Water in the firebox after rain. The crown’s primary job is directing water away from the flue opening. When the sealant cracks or the concrete deteriorates, water follows the path of least resistance down the flue liner. We document this with a camera scan to confirm the leak path isn’t coming from deteriorated flashing lower on the stack.
- White efflorescence staining the exterior brick below the crown. That chalky residue is dissolved salts left behind as water migrates through the masonry. It means water is getting past the crown and moving through the brick courses. In Fort Worth’s clay-heavy soil zones, this accelerates once it starts.
- Hairline cracks wider than a dime that reopen after sealing. Small surface cracks are normal; structural cracks that propagate through the crown body indicate the concrete has lost its tensile integrity. CrownSeal can bridge hairlines up to 1/8″, but anything wider needs structural repair or replacement.
- Pieces of concrete on the roof or ground below the chimney. Spalling, where the concrete surface flakes off in chunks, means freeze-thaw damage has compromised the crown’s interior. By the time you’re picking up pieces, water has already reached the rebar or wire mesh inside.
- Rust stains on the chimney face. These track down from the crown edge and indicate the metal reinforcement inside the crown is corroding and expanding. The expansion cracks the concrete further, accelerating the cycle. Rust stains are a late-stage signal that full replacement is likely.

AfterReplacement Cost & What’s Included
| Repair Type | Typical Range | What’s Included |
|---|---|---|
| CrownSeal application (hairline cracks, sound substrate) | $340-$520 | Surface prep, solvent contamination test, two-coat application, 5-year material warranty |
| Partial crown rebuild (cracked crown, intact base) | $580-$780 | Demolition of damaged section, form and pour new concrete, integrate existing flashing, photo documentation |
| Full crown replacement (spalling, rust, structural failure) | $780-$1,400 | Full removal, custom-formed replacement crown with drip edge, new counter-flashing integration, 10-year workmanship warranty |
What drives the range: accessibility (steep roof pitch or two-story height adds setup time), the condition of the underlying brick courses, and whether the flue tile needs reseating after crown removal. We quote the exact scope in writing before work starts, Clause 1 of the Haven Standard. No “call for pricing,” no surprises after we’re on your roof.
Every crown repair includes NFPA 211 Level 2 camera inspection of the flue below, documented photo record per Clause 4, and our 365-Day Done Right Promise. Materials come from Copperfield, Gelco, or Olympia Chimney through Haven’s buying network.
DIY or Call Us?
There’s one thing a Fort Worth homeowner can safely check: crown slope. Pour a cup of water on top. It should run off immediately toward the drip edge. If it pools, the crown has settled or eroded flat, and water will find its way in.
Everything past that observation belongs to a technician with fall protection and masonry experience. Crown work happens at height, on a sloped surface, often with compromised footing from granule loss or algae growth. The concrete itself weighs 150 pounds per cubic foot, and forming/pouring requires two hands on a roof edge. We’ve responded to calls in Wedgwood and Berkeley Place where a homeowner’s sealant job trapped water underneath, accelerating damage that a proper diagnosis would have caught.

FAQs
A properly installed concrete crown lasts 15-25 years, but Fort Worth’s combination of intense summer UV and occasional hard freezes shortens that to 10-18 years for south-facing exposures. CrownSeal reapplications every 5-7 years extend the underlying concrete. Call (682) 499-2712 and we’ll assess your crown’s remaining life with photos you can see.
Yes, if the cracks are hairline, the substrate is sound, and there’s no rust or spalling. We test with a hammer tap survey and apply CrownSeal or a similar elastomeric system. If the crack penetrates to the reinforcement or the crown has separated from the brick, replacement is the only sound option. We show you the camera footage and explain which category you’re in before quoting.
Most CrownSeal applications finish in 2-3 hours, including cure time between coats. Full replacements require a return trip: one day for form setup and pour, a second visit after 48-hour cure to strip forms and seal. We schedule both visits upfront and text when the technician is en route.
We carry CrownSeal, CF-FK flashing kits, and custom-form materials for standard residential chimney footprints. Odd-size or heritage-profile crowns are fabricated within 24-48 hours through Haven’s supplier network. For emergency water intrusion, we can install temporary weatherproofing same-day while the permanent crown is formed.
