Olympia Chimney Crown Repair: The Fort Worth Owner’s Guide
Olympia Chimney crown repair in Fort Worth typically costs $650 – $1,400 installed, depending on crown condition, flue size, and whether the underlying masonry needs rebuilding first. We stock Olympia Chimney-compatible crown materials on our trucks, so most repairs are completed the same day we diagnose them.
Most Fort Worth homeowners discover crown failure after noticing water staining on the ceiling near the chimney, or crumbling mortar pieces collecting in the firebox below. Sometimes it’s a roof inspection that flags it. Either way, the crown is the concrete cap that sits on top of the chimney and sheds water away from the flue. When it cracks, water gets behind the brick and the freeze-thaw cycles we get every winter in Tarrant County start doing real structural damage.
Key takeaways: We install Olympia Chimney-compatible crown systems. Written price before work starts. One-year written guarantee included. Call (682) 255-2144 for a free estimate.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures crown and cap systems that fit a wide range of masonry chimney configurations, not just their own branded fireplaces. The crown material we install is compatible with Olympia’s modular chimney systems, including their prefabricated and masonry retrofit lines, as well as standard brick chimneys of any brand. That matters because most Fort Worth chimneys in older neighborhoods like Fairmount or Ryan Place are traditional masonry, and the crown has to be formed to the actual flue tile dimensions on site.
Here’s the compatibility gotcha we see regularly: the crown is sized by the outside dimensions of the flue tile and the inside dimensions of the chimney chase, not by the fireplace model number. An Olympia crown system shipped as a “one size fits most” kit rarely fits correctly without field adjustment. We measure, form, and pour or install the crown to the exact dimensions of your flue, then seal it with a flexible crown coat rated for the thermal movement we see in North Texas.
OEM Olympia Chimney crowns are quality products. For certain applications, we also specify aftermarket crown systems from Gelco or form custom pours using professional-grade crown mix. The decision comes down to flue geometry, climate exposure, and whether the existing crown is repairable or needs full replacement. We’ll show you the measurements and explain which option fits before any work is authorized.
Styles & brands we work with





Signs Your Olympia Chimney Crown Repair Is Failing
- Water stains on ceiling or walls near the chimney. A cracked crown lets rainwater run down inside the chase. By the time you see interior staining, water has been entering for months, and the flue liner may have begun to rust or deteriorate.
- Crumbling mortar or concrete pieces in the firebox or on the roof. Freeze-thaw cycling in Fort Worth winters breaks the crown apart from the edges inward. Those pieces you’re finding are the crown disintegrating.
- Efflorescence (white chalky residue) on the exterior brick near the top. Water is moving through the masonry and depositing minerals on the face of the brick. It’s a sign the crown has stopped doing its job.
- Rust stains running down the chimney exterior. The metal flue cap or damper assembly is rusting because water is getting in from above. Crown cracks are the most common entry point.
- A musty fireplace smell, especially after rain. That’s moisture sitting inside the flue and firebox. The crown is supposed to keep the top of the chimney dry, and when it doesn’t, damp air settles in the firebox.

AfterReplacement Cost & What’s Included
A full Olympia Chimney-compatible crown replacement in Fort Worth runs $650 – $1,400 installed. The spread depends on three things: how much of the old crown has to be removed, whether the top courses of brick need repointing before the new crown goes down, and the flue tile configuration (single flue vs. multiple flues).
Every quote includes complete removal of the failing crown material, inspection of the flue tile and top masonry courses, form and pour or install of the new crown with proper overhang and drip edge, application of a flexible crown sealant, and full cleanup. The written price you approve before we start is the price on the invoice. No line items added at the door.
Every crown repair carries our 365-Day Done Right Promise: a written guarantee valid for one full year. If the crown fails within that period for any reason covered under the guarantee, we return at no charge and make it right. That guarantee is in writing, on every repair, by Hank Delano’s standing order.
DIY or Call Us?
You can safely inspect the crown yourself if you can access the roof and are comfortable on a ladder with proper fall protection. Look for visible cracks wider than a credit card, missing chunks of concrete, or standing water pooling on the crown surface after rain. That’s information we’ll use on the phone to give you a rough idea of what we’re dealing with.
Where DIY goes wrong on crown work is the crown material itself. A hardware store crown patch product applied over a failing crown buys you a season at best in Fort Worth’s freeze-thaw climate. Once water has worked its way behind the brick, surface patching traps moisture inside and accelerates spalling. Proper crown repair means removing the compromised material, evaluating what’s underneath, and rebuilding with a product rated for chimney crown exposure. We’ve pulled off more than a few patch jobs in the Fairmount Historic District that lasted one winter before the bricks started popping.
If you want the diagnosis and a written price, call (682) 255-2144. We do the inspection, we show you what we see, and you decide. If it is not clean and it is not safe, we are not done.
FAQs
A properly installed chimney crown with a flexible sealant coat lasts 20 – 30 years in North Texas, but the sealant typically needs reapplication every 5 – 8 years. The two biggest enemies of crown lifespan in Fort Worth are freeze-thaw cycling from winter ice and UV degradation of the sealant layer from our long, hot summers. Call (682) 255-2144 and we’ll assess the crown and tell you exactly what condition it’s in and what it needs before burning season.
Yes, if the cracks are hairline and the crown is otherwise structurally sound, we can fill and reseal the crown with a flexible sealant, which typically runs $250 – $500 in Fort Worth. If the crown is crumbling, spalling, or separated from the flue tile, a patch will fail within a year or two and replacement is the honest recommendation. We’ll show you photos from the roof before you decide. Call (682) 255-2144 to schedule an inspection.
Most Olympia Chimney-compatible crown replacements are finished in 4 – 6 hours on site, including removal, form work or install, sealing, and cleanup. The chimney should stay unused for 24 – 48 hours afterward while the crown material cures. Call (682) 255-2144 and we’ll schedule a window that fits your week.
We stock Olympia Chimney-compatible crown materials, along with DuraFlex liner components, HeatShield repair materials, and Gelco sealants on our service trucks.
