Olympia Chimney Chimney Cap Installation: The Fort Worth Owner’s Guide
We stock and install Olympia Chimney-compatible chimney caps throughout Fort Worth, with most replacements running $245 to $510 including the cap, fasteners, sealant, and labor. If you’re reading this, odds are you looked up on a bright Saturday and saw a cap that’s rusted through, cocked sideways, or missing entirely after one of our spring windstorms. The fix usually takes about an hour from ladder to cleanup.
Most Fort Worth homeowners discover the failure two ways: a cap lying in the yard after a north Texas storm, or water staining on the ceiling near the chimney chase. Either way, the cap is the first line of defense for your flue, and a failed one lets rain, birds, and embers into places they don’t belong.
Which Olympia Chimney Models This Applies To
Olympia Chimney builds caps for both masonry flues and factory-built chimney systems, and the mounting method differs sharply between the two. If you have a round flue tile sticking out of a brick chimney, you need an Olympia outside-mount cap that slips over the tile’s outer edge using a pressure band or set screws. If you have a metal chimney pipe, you need an inside-mount cap that seats into the pipe bore; that’s the number one compatibility mistake we see on Fort Worth rooflines.
Measure before you buy. For outside-mount caps, measure the flue tile’s outside length and width. For inside-mount, measure the pipe’s inside diameter. Olympia caps for typical Fort Worth homes run anywhere from a 6-inch inside mount on a fireplace pipe to a 13″ x 18″ outside mount on a masonry fireplace flue. We keep most of these sizes on the truck. Flint Chimney Co Fort Worth is an independent service provider, not a distributor or affiliate of Olympia Chimney, so when we specify a cap we match the size and mounting style to your chimney, not to whichever box is sitting closest to the bench.
OEM versus aftermarket matters less with caps than with liners; what matters is stainless steel versus galvanized. Olympia’s stainless caps hold up far better against Fort Worth’s heat and thunderstorm cycles than cheaper galvanized units, which typically rust through at the weld points within three to five years on a south-facing flue. We specify stainless on every cap replacement unless there’s a real reason not to.
Styles & brands we work with
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Water staining on the ceiling around the chimney chase. A cap with rusted welds or a missing spark screen lets rain drive straight down the flue and into the framing around the chase. In Fort Worth, the damage usually shows up first after a west wind storm drives rain sideways.
- Rust streaks down the chimney crown or siding. A galvanized cap that’s started to fail sheds oxidized metal onto the brick or chase each time it rains. The streaks are superficial, but they tell you the cap’s metal is actively corroding.
- Birds or squirrels inside the fireplace. A cap with a damaged or missing mesh screen is an open door for chimney swifts and squirrels. We have pulled enough nesting material out of Fort Worth flues to fill a dumpster; the mess behind an unscreened cap is expensive to remove.
- Debris in the firebox after storms. Leaves, twigs, and even gravel from the roof show up in the firebox when the cap is gone or the spark screen has a hole big enough for the wind to work through. That same opening is where embers go out and start trouble.
- Visible cap damage from the ground. A cap tilted at an angle, a missing lid, or a top screen peeled back by wind all mean the cap is no longer doing its job. Fort Worth gets enough wind shear that we replace caps every year that were installed correctly on day one and simply wore out from exposure.
Replacement Cost & What’s Included
A chimney cap replacement on a Fort Worth home typically runs $245 to $510 installed. The spread depends mostly on the cap size and mounting style: a small 6-inch inside-mount stainless cap is on the low end; a large stainless outside-mount cap for a brick fireplace flue with a heavy storm band sits at the top. If the old cap’s mounting screws are seized or the flue tile has a chip at the lip, the prep work adds a little time, but we tell you that before we start.
Every price we give includes the cap, stainless fasteners, weatherproof sealant, labor, ladder work, and disposal of the old part. We put the total in writing before any work starts, and that number is the number on your invoice. No adjustments at the door, no “while we’re up there” additions. The work carries our 365-Day Done Right Promise: if the cap fails or shifts within a year, we return and make it right at no charge. Hank Delano has stood behind that guarantee for years, and he writes it on every repair slip with his own initials.

AfterDIY or Call Us?
You can do a dry-ground inspection on a chimney cap: look for rust, missing mesh, and shifting. What you should not do, unless you are genuinely comfortable on a ladder against a roofline and you have the right fasteners on hand, is climb up there and swap a cap yourself. Most Fort Worth chimneys put the cap two stories up on a sloped roof; working over the edge with both hands on a cap leaves nothing holding you to the ladder. That is the honest answer, and it is why we do not sell caps as a walk-up retail part with a nod toward the roof.
If you want to inspect it yourself from the ground, use binoculars, look for the symptoms above, and leave the roof work to us. Call (682) 255-2144 and we’ll bring the right cap for your flue size, the right fasteners, and the right ladder gear. The swap is quick; the fall risk is not worth the savings.
FAQs
A stainless Olympia cap typically lasts 10 to 15 years on a Fort Worth roof, while a galvanized cap usually lasts 3 to 5 years before rust compromises the welds or the mesh starts to break down. South-facing flues take more sun and storm abuse, so they wear out first. If you’re not sure which metal is on your roof, call us and we can tell you during the sweep.
Sometimes, if the failure is limited to the spark screen or a single set screw, a repair makes sense; if the lid is warped or the weld seams are rusted through, you’re better off replacing the cap. We show you the cap with photos from the roof and let you decide based on what we see. We won’t sell you a replacement when a repair is honest work.
A standard chimney cap installation takes about one hour from truck to cleanup, including setting up roofing ladders, removing the old cap, prepping the flue lip, mounting the new cap, and sealing the fasteners. If the old mounting hardware is heavily rusted, add about twenty minutes. We schedule it as a single visit, and we leave nothing behind but the new cap.
We keep the most common Olympia-compatible stainless cap sizes on the truck, including round inside-mount caps and square outside-mount caps for masonry flues. If you have an unusual size, we can usually source the right cap same week. We also work with DuraFlex, HeatShield, and Gelco parts when the job calls for a different brand, and we’ll tell you which part is going on before we order it.
Get the Right Cap On the Right Flue
If your Olympia Chimney cap is rusted, missing, or letting rain into your chimney, call (682) 255-2144. We’ll confirm your flue size, quote the cap and the labor in writing, and install it properly. If it is not clean and it is not safe, we are not done. That is the Garrison Standard, and it applies to every cap we put on a Fort Worth roof.
