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.
Olympia Chimney Chimney Cap & Crown in Norwalk: What to Know First
We repair and replace Olympia Chimney caps and crowns throughout Norwalk, CT, usually within the same week you call. A standard cap replacement on an Olympia Chimney flue runs $275-$475, while crown repair or coating typically lands between $350 and $650 depending on damage. Every job starts with a camera inspection and a straight answer on what actually needs doing, and the price we quote before work begins is the price on the invoice.
If you own a home in Norwalk with an Olympia Chimney product on the roof, this page covers what fails on their caps and crowns, what it costs to fix, and why we handle these jobs the way we do. Call (475) 375-2748 and you’ll get a live person, not a call tree.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney galvanized caps corrode at the mesh seam. The standard Olympia Chimney cap uses a galvanized body with a mesh screen. In Norwalk, salt air off Long Island Sound, combined with wet Connecticut winters, eats through the seam where the mesh meets the cap frame. We see this every fall in East Norwalk and Rowayton, and the fix is a replacement with a heavier-gauge cap, not a patch job that buys you six months.
- Crown cracking on Olympia Chimney masonry flue terminations. The crown is the concrete slab that seals the top of the chimney around the flue. On Olympia Chimney installations with masonry terminations, we find hairline cracks widening every freeze-thaw cycle. Water gets in, freezes, and spalls the crown surface. If caught early, we clean, fill, and coat with a flexible crown sealer. If it’s gone too far, we form and pour a new crown with a proper drip edge and expansion joint around the flue tile, which most original Norwalk installs never had.
- Olympia Chimney stainless steel caps loosen on the flue collar. Olympia’s stainless caps come with a pressure-fit collar and set screws. After a few seasons of thermal expansion and contraction, those screws back off and the cap begins to rattle in the wind, or worse, lift off. We replace worn set screws with stainless hardware coated in anti-seize, and we add adhesive where the crown is sound enough to accept it. If the flue tile itself is chipped or out of round, we’ll tell you before we order anything.
- Delaminating pre-cast crowns on factory-built Olympia Chimney units. Olympia Chimney builds pre-fab fireplaces where the cap and crown are integrated into the chase termination. The crown material on some of their older factory-built units separates at the lamination seams. You’ll see bubbling or peeling on the crown surface from the ground. That lets water wick down into the chase, and in Norwalk, that means rusted chase covers and damp insulation. We repair these with a crown coat system, and if the underlying cap is compromised, we install a custom cap that fits the unit’s chase pan.
- Snow and ice damage to Olympia Chimney multi-flue caps. Norwalk gets real snow, and ice dams on the roof can slide into the cap and knock it off or bend the frame. Olympic Chimney multi-flue caps are sturdy but not snowplow-proof. If yours is dented or sprung, we replace it with a cap sized correctly to your flue array, and we check the surrounding roof flashing at no extra charge while we’re up there.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and talk to a person. You’ll reach Wendell or one of his crew. We’ll ask what you’re seeing, what the chimney serves, and when you last had a sweep. We set a real arrival window.
- 2
We inspect from the roof, not the driveway. A ladder goes up, and we look at the cap, the crown, the flue tile, and the chase. Every inspection includes camera footage of what’s actually up there.
- 3
We show you the video before we recommend anything. If the cap is salvageable, we’ll say so. If the crown needs coating, you’ll see the cracks. Nothing gets sold off a guess.
- 4
Parts decision: OEM when it matters, quality aftermarket when it doesn’t. For Olympia Chimney factory-built units, we stay with parts that preserve the unit’s UL listing. For standard cap replacements, we’ll offer options, including heavier-gauge stainless that outlasts what was originally installed.
- 5
The repair. Caps get correctly sized and mechanically fastened or adhered. Crowns get cleaned, repaired, and sealed with proper expansion joints and drip edges. We clean up every scrap before we leave.
- 6
The test and the guarantee. We run water over the repaired surface to confirm it sheds properly, then we walk you through what was done. Every job carries our 90-Day Done Right Promise in writing.

FAQs
We don’t administer Olympia Chimney warranties, since we’re an independent provider. What we can tell you is whether the failure is a warranty-type defect or wear-and-tear, and we’ll give you honest counsel on whether a warranty claim is worth pursuing. Bring us the model and serial numbers if you have them.
If the cap body is intact and the issue is a rusted mesh or failed set screws, we can usually repair the existing Olympia cap. If the frame itself is corroded or the cap was lifted off by ice, replacement is the honest call. We’ll show you photos of the cap before deciding.
Most single-flue cap replacements are done in one visit, typically an hour on the roof plus setup and cleanup. Multi-flue or custom work may take longer. We schedule Norwalk jobs Monday through Saturday, and same-week appointments are the norm in our service window.
A hairline crack in a Norwalk crown will widen with every freeze-thaw cycle, and the damage accelerates once water gets into the chimney structure. If it’s a surface crack, sealing it now is cheap. If you wait until chunks of crown are missing, you’re looking at a full re-pour. We’d rather fix it early and tell you it only needed sealing.
That rattle means your Olympia cap’s set screws have backed off or the flue collar is out of round. A loose cap eventually lifts off in a Norwalk storm or gets torn by ice. Call us at (475) 375-2748 and we’ll get it secured before it becomes a missing cap, and we’ll check the crown while we’re up there. Estimates are free.
