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.

AfterOlympia Chimney Chimney Cap Installation: The Joliet Owner’s Guide
Olympia Chimney chimney cap installation in Joliet typically runs $285-$475 for a standard single-flue cap, including the cap, flashing collar, and labor. We stock Olympia Chimney-compatible caps in common sizes on our Joliet trucks and can usually measure, match, and install within one booked visit. Most homeowners realize their cap has failed when water starts dripping onto the firebox floor or when a neighbor spots rust stains running down the brick.
Corrine Halstead and our crew have replaced hundreds of these across Joliet, from the bungalows near the Joliet Iron Works Historic Site to newer builds in Shorewood. The photo doesn’t argue. It just shows you what’s there, and with chimney caps, what we usually find is a rusted-through mesh, separated seams, or a cap that’s blown clean off in a Will County wind gust.
Which Olympia Chimney Models This Applies To
Olympia Chimney caps are not one-size-fits-all. The company produces caps for its own factory-built chimney systems, including the Olympia 400 and 600 series stainless steel chimneys, plus universal-fit caps designed for masonry flues. The critical identifier is the flue diameter, measured inside-to-inside at the top course of brick or the chase cover opening. Common Olympia Chimney cap sizes we see in Joliet are 8″, 10″, and 13″ round, plus 9″×13″ and 13″×18″ rectangular for multi-flue applications.
Here’s where owners get tripped up: Olympia Chimney factory caps for their 400/600 series use a twist-lock collar that mates to a specific chase cover profile. A generic big-box cap will sit on top but won’t lock, and in a Joliet winter with freeze-thaw cycling, that cap walks itself loose by February. We source OEM-pattern Olympia Chimney caps through Haven’s buying network, plus equivalent-grade caps from Gelco and Famco when the original spec has been discontinued. We measure with a tape, not a guess, and we show you the collar fit on camera before we bolt anything down.
Signs Your Olympia Chimney Chimney Cap Is Failing
- Rust stains on the chimney breast or exterior brick. Olympia Chimney caps use 304 or 430 stainless mesh and lid, but the spot-welded corners and the ring that cinches to the flue are the first to corrode. Once rust bleeds through, the metal is thinning fast, not just discoloring.
- Water in the firebox or a damp, musty smell days after rain. A cap’s primary job is to shed water. If the lid has deformed from heat cycling or the mesh has pulled away from the frame, rain enters the flue, runs down the liner, and pools in the smoke shelf. In Joliet’s clay-heavy soil, that moisture has nowhere to go but into your basement air.
- Debris, leaves, or bird nesting material visible from below. The ¾” mesh on an Olympia Chimney cap is supposed to block anything larger than a spark. When the mesh rusts through or a corner gap opens, squirrels and starlings treat your flue like a rental property. We pulled a full nest from a Jefferson Avenue chimney last spring, the cap’s mesh completely gone on one side.
- The cap is visibly tilted, shifted, or missing entirely after wind. Will County sees sustained winds over 30 mph several times each winter. A cap secured with only two sheet-metal screws, or one where the flue collar has corroded, becomes a projectile. We’ve found Olympia Chimney caps in Joliet yards, in gutters, and once on a neighbor’s deck.
- Spalling brick or deteriorating mortar at the chimney top. This is the slow-motion failure. A cap that no longer sheds water evenly lets moisture saturate the crown and freeze. By the time you notice flaking brick faces, the cap has been failing for two or three seasons. The cap is cheap; the crown rebuild is not.

AfterReplacement Cost & What’s Included
| Service | Price Range |
|---|---|
| Single-flue Olympia Chimney cap, standard stainless | $285-$375 |
| Multi-flue or oversized cap (13″×18″ and up) | $395-$475 |

| Flue collar repair or custom adapter fabrication | Add $85-$150 |
Every cap installation in Joliet includes removal and disposal of the failed cap, measurement and fit verification, stainless steel hardware (not aluminum, which galvanically corrodes against the cap frame), and a camera inspection of the flue top to confirm no debris or damage is hidden below. The price you see above is the price on your written scope before we start, per Haven Standard Clause 1. Work is backed by our 365-Day Done Right Promise. Materials come through Haven’s buying network, sourced from Olympia Chimney, Gelco, Famco, and Copperfield, so we’re not marking up a retail part and calling it specialty.
DIY or Call Us?
You can safely check whether your cap is loose by sight from the ground with binoculars, or from a ladder if you’re comfortable at gutter height. Do not climb onto the roof. Chimney work above the eave line combines steep pitches, often moss-slick brick, and a long drop. We’ve responded to homeowner falls in Joliet, and a cap replacement is not worth an ER visit.
What goes wrong with DIY cap installation: the flue is rarely perfectly round after years of heat cycling, so the collar clamp needs hand-fitting. The mesh must face the right direction to shed sparks per NFPA 211. And without a camera down the flue, you won’t know if the cap failure already let water damage the liner below. We bring the camera, the fitted cap, and the documentation. Call (815) 620-5234 and we’ll book a time that works.
FAQs
How long does an Olympia Chimney cap last in Joliet?
A quality stainless cap typically lasts 12-18 years in Will County’s climate, but the freeze-thaw cycles and road salt aerosol near I-80 and Route 53 can shorten that to 8-12 years on east-facing exposures. We inspect cap condition as part of every sweep and tell you when replacement is approaching, not when it’s overdue. Call (815) 620-5234 for a free estimate.
Can a rusted Olympia Chimney cap be repaired instead of replaced?
Spot-welding rusted mesh or patching a separated seam is temporary at best. Once 304 stainless has pit corrosion, the metal is compromised and will fail again within a season. We don’t patch caps for the same reason we don’t patch brake lines. Replacement is the honest recommendation, and we show you the corrosion on camera before we quote. Call (815) 620-5234 for a free estimate.
How long does the installation take?
Most Olympia Chimney cap replacements in Joliet take 45-90 minutes from ladder set to final photo. If the chase cover or flue collar needs work, plan on 2-3 hours. We don’t rush; we document. You’ll get the photo record before we leave, per Haven Standard Clause 4. Call (815) 620-5234 to book.
Do you stock Olympia Chimney caps, or is there a wait?
We stock the common Olympia Chimney-compatible sizes, 8″ through 13″ round and standard rectangular, on our Joliet trucks. Less common sizes or factory 400/600 series twist-lock patterns we pull overnight from Haven’s supplier network. We don’t book the install until we confirm the part is in hand. Call (815) 620-5234 to check availability for your flue size.
