Olympia Chimney Chimney Cap Installation: The Jacksonville Owner’s Guide
We install Olympia Chimney-compatible chimney caps across Jacksonville for $285 to $520 installed, depending on flue size and whether your crown needs repair before mounting. Most jobs are completed same-day, and we stock the common 8″, 10″, and 13″ round caps plus standard rectangular sizes on every truck. If it’s worth burning wood in, it’s worth doing the maintenance right.
Most Jacksonville homeowners figure out their chimney cap has failed when water starts showing up where it shouldn’t, or when a neighbor mentions rust stains running down their brick. In Riverside and Avondale, we see a lot of older galvanized caps that have simply rotted through after fifteen humid summers. In the newer subdivisions out toward Nocatee, it’s often builder-grade caps that blew loose in a named storm and nobody noticed until the fireplace started smelling like a wet dog.
Which Olympia Chimney Models This Applies To
Olympia Chimney produces caps across several product lines, and the mounting method changes depending on what you’re working with. Their standard galvanized and stainless single-flue caps use an outside-mount leg system with set screws that tighten to the flue tile. The Wind Directional cap, popular in coastal Jacksonville for its passive draft assist, requires a slightly different leg spacing and won’t seat correctly on a flue that’s been ground down or repaired with Portland cement.
To identify your cap, look for the Olympia stamp on the underside of the lid or on one leg. If the stamp’s rusted away, measure the outside dimension of your flue tile, not the chimney crown. A 13″ x 13″ flue tile takes a 13″ cap, but we’ve found Olympia’s tolerances run tight, a 12-3/4″ actual measurement can mean the difference between a slip-fit and a return trip.
We carry OEM Olympia caps and stainless equivalents from Gelco and Famco. The OEM fits exactly as designed. The aftermarkets we stock use heavier-gauge 304 stainless and often outlast the original in salt-air conditions. For homes within five miles of the St. Johns River or the Intracoastal, we typically recommend stepping up to marine-grade stainless regardless of what was there before.
Signs Your Olympia Chimney Chimney Cap Is Failing
- Water in the firebox after rain. The cap’s mesh screen has separated from the frame, or the lid has warped enough to let wind-driven rain slip past the overhang. In Jacksonville’s afternoon thunderstorms, it doesn’t take much of a gap.
- Rust streaks down the chimney face. Galvanized caps lose their zinc coating eventually, especially where salt air accelerates corrosion. Once rust starts, the cap is eating itself from the inside out. We’ve pulled caps off Ortega homes that looked fine from the ground and crumbled in our hands.
- Birds or squirrels in the flue. The mesh sides have corroded through or been bent by a falling branch. Florida’s squirrel population doesn’t sleep through winter; they’re looking for warm cavities year-round, and a missing or damaged screen is an open door.
- Draft problems or smoke rollout when starting a fire. The Wind Directional cap has frozen in position, or the entire cap has shifted and is now blocking part of the flue opening. This one can be subtle, the fire still draws, but it takes longer to establish and smokes into the room on light-off.
- The cap is visibly tilted or missing after a storm. Jacksonville’s summer storms and the occasional tropical system generate enough wind to peel off a poorly secured cap. If yours is gone entirely, call before the next rain, an open flue is a direct path for water into your chimney system.
Replacement Cost & What’s Included

The range depends on three things: cap material, accessibility (steep roof, two-story height, or tight clearance), and whether your crown is sound enough to anchor to. We quote upfront after looking, not after guessing. The number on the estimate is the number on the invoice. Every cap installation carries our 90-Day Done Right Promise, in writing, no arguing.
DIY or Call Us?
There’s nothing mysterious about a chimney cap, it’s a lid with legs. If you’re comfortable on a ladder, have a stable roof pitch, and your flue is easily accessible, checking the fit of a replacement is reasonable homeowner work. Measure twice, buy once, and don’t force a tight fit that cracks flue tile.
Where DIY goes wrong: working on a steep or second-story roof without proper fall protection, discovering the crown is crumbly only after you’ve committed to the mount, and the common mistake of installing a cap that sits too low and blocks draft. We’ve also seen homeowners seal the mounting legs with roofing tar, which looks correct and guarantees a leak in two years when it cracks. If you’re not certain about the crown condition or the roof makes you nervous, that’s what we’re for. Call (833) 974-6113 and we’ll give you a straight answer about whether this is a DIY job or a service call.
FAQs
Galvanized caps typically last 10 to 15 years in inland Jacksonville, but half that within a few miles of salt water. Stainless caps, properly installed, often go 20 years or more. The mesh is usually what fails first, it collects acidic condensation and, near the coast, salt spray accelerates pitting. Call (833) 974-6113 and we’ll check what you’ve got and what makes sense to replace it with.
Minor mesh damage can sometimes be patched, but warped lids, rusted-through frames, or separated welds mean replacement. We’ve tried to save homeowners money with repairs, but a cap that fails again in eighteen months isn’t a savings. We stock replacements on the truck so you’re not waiting on an order. For a free look and honest verdict, call (833) 974-6113.
Most cap replacements take 45 minutes to an hour and a half, including removing the old unit, inspecting the flue and crown, and securing the new cap. If crown repair is needed, add an hour for proper curing time before mounting. We complete most jobs in a single visit. Call (833) 974-6113 to schedule, estimates are free.
We stock the common Olympia Chimney sizes and equivalents from Gelco and Famco on every service truck. Odd sizes or special-order finishes take two to three business days. When you call (833) 974-6113, we’ll confirm your flue size and have the right cap on the truck when we arrive.
