Olympia Chimney Chimney Cap Installation: The Fort Worth Owner’s Guide
Chimney cap installation for Olympia Chimney systems in Fort Worth typically runs $385 to $680 installed, depending on the cap style and whether we’re replacing an existing mount or adding one where none existed. Most Olympia Chimney-capable swaps take about 60 to 90 minutes once we’re on the roof, and we stock common Olympia-compatible sizes on the truck. The way most people find us is the same story every time: they hear something clanking in a storm, or they spot a rust-streaked cap hanging off the flue tile from the backyard, or a bird has decided the open flue is now a rental property.
We’re an independent service provider in Fort Worth. We install and service chimney caps that fit Olympia Chimney systems, but we’re not affiliated with Olympia Chimney itself. That actually works in your favor: we carry both OEM Olympia caps and quality equivalents, so you get an honest recommendation on what’s worth spending on and what isn’t.
Which Olympia Chimney Models This Applies To
Olympia Chimney makes caps sized for their stainless steel and galvanized chimney systems, most commonly the Ventis and Olympia air-cooled chimney lines. The cap on these systems isn’t a universal one-size-fits-all part. It’s matched to the inner flue diameter and the outer pipe dimension of the specific model. That’s the first compatibility gotcha we see in Fort Worth: a homeowner buys a “universal” cap online, gets it on the roof, and finds the mounting collar is either too tight to seat or too loose to stay put when the Texas wind kicks up. The outer diameter on Olympia systems varies enough between model years that we always verify the measurement before recommending anything.
Here’s how to identify what you have. Look for the manufacturer label on the chimney pipe itself, usually on a section visible in the attic or where the pipe passes through the ceiling. It will list the model and diameter. If that label is gone or illegible, we measure the inner flue and the outer pipe OD on site. That takes about five minutes and removes all guesswork. For OEM Olympia parts, the cap is engineered to match the pipe’s specific tolerances. For aftermarket equal-quality straps and caps, we only install brands with a track record in this climate, because Fort Worth’s freeze-thaw cycles and spring hail punish cheap metal fast. Cory Mitchell has pulled too many dented bargain caps off chimneys near TCU to stock anything we can’t stand behind.
Styles & brands we work with





Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Rust streaks running down the cap or the chimney chase. This means the protective finish has failed and moisture is working into the metal. On galvanized caps, once the zinc layer is compromised in Fort Worth’s humidity and rain, the rust spreads from the inside out.
- A cap that’s leaning, loose, or hanging by one bracket. The mounting hardware has either corroded or worked loose from wind. A leaning cap pulls rain into the flue on one side and lets critters in on the other. You’ll see this most often after a spring storm front moves through.
- Birds, squirrels, or their nesting material visible at the flue opening. The spark arrestor mesh has a gap or the cap has shifted enough to create an entry point. We’ve found entire nests built against non-functional caps on older Fort Worth homes.
- Water staining on the ceiling near the chimney chase or a damp smell from the fireplace. A failed cap lets rain follow the flue down. What starts as a cap issue ends up looking like a roof leak, and both need a look.
- A rattling or scraping sound in high wind. Loose hardware or a cracked mounting band. It’s the chimney telling you the cap is working against the pipe, not with it.
Replacement Cost & What’s Included
For an Olympia Chimney-compatible cap installed in the Fort Worth area, expect $385 to $680. The range depends on three things: whether this is a straight swap of an existing cap, whether we’re adding a cap where none existed (which means fabricating or fitting a mount), and the specific cap style, whether it’s a standard single-flue cap, a multi-flue cap, or a custom top-mounted draft-enhancing cap. The part itself is usually $85 to $240 of that total. The rest is the labor to safely access the flue, remove the old cap and hardware, prep the mounting surface, and verify fit and function.
Every quote comes as a written price before any work starts. No cap swap at Hadley Chimney Fort Worth is quoted verbally and invoiced higher later. The written price covers the cap, hardware, installation, clean-up, and before/after photos so you can see exactly what was done on your roof. Every repair and cap installation carries our 365-Day Done Right Promise in writing. If the cap mount fails within a year, we come back and make it right at no charge. That’s not a promo. It’s the standing guarantee on every job we do.

Honest answer: replacing a chimney cap means working on the roof, often at the highest point of the house, and that’s where a DIY job goes wrong. The cap itself is low-risk to handle. It’s the ladder on uneven Fort Worth ground, the roof pitch, the slope, the edge, and the wind. A chimney cap costs between $85 and $240 as a part. A fall from a roof costs far more than the difference between DIY and hiring someone with proper gear and fall protection. Our techs are background-checked, uniformed, and trained to work on that particular point of the house safely.
What you can check from the ground: use binoculars or a phone camera at full zoom to look for rust, leaning, or visible gaps. That photo is genuinely useful to us on the call. If it looks compromised, call (682) 900-6393. We’ll set a tracked arrival window, get eyes on it, and give you a written price before we touch anything. I’d rather show you a photo of the problem than hand you a bill you don’t understand.
FAQs
In Fort Worth’s climate, a quality stainless steel cap on an Olympia system typically lasts 8 to 15 years, while galvanized caps tend to run 5 to 8 years before rust becomes structural. The deciding factors are hail exposure, storm frequency, and whether the cap was sized correctly in the first place. If your cap is past that range and showing rust streaks or loose hardware, call (682) 900-6393 and we’ll give you an honest read on whether it’s time.
Sometimes yes, if the damage is limited to the mesh or a single mounting bracket and the cap body is still solid. We carry replacement mesh and hardware on the truck for common Olympia sizes. But if the cap body is rusted through, dented from hail, or the mounting band is cracked, repair is throwing money at a part that’s already failed. Call (682) 900-6393 and we’ll tell you straight which side of the line yours falls on.
Most Olympia Chimney-compatible cap installations in Fort Worth take 60 to 90 minutes once the technician is set up on the roof. That includes removing the old cap, prepping the mount, installing the new cap and hardware, verifying the fit, and taking photos. If the old mount is damaged and needs a new base fabricated, add 30 to 45 minutes. We’ll give you a written price and time estimate before any work starts.
We stock the most common Olympia Chimney-compatible cap sizes on the truck, plus equivalent-quality caps that fit the same flue dimensions. Oddball sizes and custom multi-flue layouts may take a few days to order. When you call (682) 900-6393, we’ll ask for the model or measurements and tell you before anyone heads out whether we’re installing same-visit or need to place an order first. We also work with parts from DuraFlex, HeatShield, and Gelco, so we can usually match what your chimney needs.
