If that’s you, call (914) 233-3156 and we’ll get someone out to look.
How Olympia Chimney Products Fail – and How We Fix Them
Olympia Chimney makes solid components, but every brand has its weak points, and Yonkers weather finds them faster than most places. Here are the failure modes we see most often on Olympia Chimney systems in this area:
- Olympia Chimney stainless steel liner corrosion at the flue cap seam. Olympia’s rigid and flexible liners hold up well against creosote (the flammable tar buildup that makes chimneys a fire risk), but the seam where the liner meets the cap takes direct rain and freeze-thaw cycles all winter in Yonkers. We regularly see rust blooming right at that joint. The fix is a replacement cap with a proper storm collar, and in some cases a short section of new liner if corrosion has crept down a foot or more. We’ll always camera the interior to confirm how far the damage goes before cutting anything.
- Mortar crown cracking on Olympia Chimney masonry assemblies. Olympia’s modular block systems go together cleanly, but the crown (the concrete slab on top of the chimney) is poured on-site and that’s where shortcuts happen. A crown with no expansion gap or one poured too thin cracks within a few years, and water gets behind the flue tiles. In Yonkers, where winter nights drop below freezing regularly, the freeze-thaw pop widens those cracks fast. We grind out the old crown, pour a proper overhanging crown with a drip edge, and seal it with a breathable water repellent.
- Olympia Chimney cap screen clogging from Yonkers tree debris and nesting. We pull a surprising number of bird and squirrel nests out of Olympia caps every spring in Yonkers, especially in neighborhoods with mature oaks like Bryn Mawr and Beech Hill. The standard mesh on many Olympia caps is wide enough to let starlings thread nesting material through. Clogged mesh means poor draft and smoke backing up into the living room. We replace the cap with a finer mesh or a full-coverage design that stops both debris and animals.
- Spalling brick on the exterior face of Olympia Chimney-block systems. The factory blocks are fine, but the face brick applied over them is standard clay brick, and Yonkers brick soaks up water like a sponge. Spalling (the face popping off in flakes) happens when moisture trapped in the brick freezes and expands. Once the face is gone, the softer interior is exposed and deterioration accelerates. We cut out the damaged brick, replace it with matched units, and apply a siloxane-based waterproofing that lets the masonry breathe while shedding water.
- Flashing separation where the Olympia Chimney stack meets the roof line. The flashing (the metal strips where the chimney meets the shingles) is not an Olympia product, but it’s the most common point of water intrusion on any chimney, and we see it fail frequently around Yonkers roof-pitch changes. Step flashing that’s pulled away, rusted at the corners, or sloppily caulked lets water run straight down the chimney chase and into your ceiling. We cut new step flashing in, counter-flash into the mortar joints, and test the seal before we leave the roof.

Our Olympia Chimney Chimney Repair Process
Here’s what actually happens when you call us about an Olympia Chimney problem:
- 1
You call (914) 233-3156 and talk to a live person, not a voicemail tree. We ask what you’re seeing, get your Yonkers address, and book a window that works around your schedule, with live arrival tracking so you know when the tech pulls up.
- 2
We run a camera inspection of the full flue before touching a single brick. You get to see the footage. We point out exactly what’s wrong, what’s fine, and what can wait. If there’s no camera evidence of a problem, we don’t claim there is one.
- 3
Parts decision on the spot: OEM Olympia Chimney components or a qualified aftermarket equivalent. For liner sections and caps, OEM is the safest call if it’s available and reasonably priced. For components like flashing, mortar, and waterproofing, we use materials that match or exceed the original spec. You get a written price before we start using any of them.
- 4
We make the repair. Repointing, brick replacement, liner work, cap replacement, waterproofing, flashing, rebuilding – we handle all of it in-house with our own crew.
- 5
Photo documentation of everything. You’ll see the before, the during, and the after. If a repair fails within 365 days, our Done Right Promise means we come back and fix it free. That’s a written guarantee on every job, not a handshake.

Our techs are background-checked and uniformed, so you know exactly who’s walking up your driveway in Yonkers, and you’ll get live arrival tracking through the Relay Visibility Guarantee, not a four-hour window that forces you to burn a vacation day.

If an Olympia Chimney part is backordered or discontinued, we usually have a compatible alternative on the truck the same week.
FAQs
No, not with us. As an independent Olympia Chimney service provider, we do not alter manufacturer warranties, and we use OEM Olympia Chimney parts where available and quality equivalents where they’re not. If you have an active warranty claim, we’ll help you document the failure properly so you can pursue it. The workmanship warranty we provide is ours, in writing, for 365 days. Call (914) 233-3156 if you want us to assess your chimney and tell you plainly whether a warranty claim makes sense.
Most repairs are finished in one visit, usually within a week to ten days of your call depending on the crew schedule and weather. Cap replacements, flashing work, and mortar repointing are single-day jobs. A full rebuild above the roof line may take two to three working days. Call (914) 233-3156 and we’ll give you a straight answer on timing for your specific repair.
It depends on how much usable liner is left and where the damage is. If corrosion is isolated to the top two feet near the cap, a section replacement with a proper connector is often a solid repair. If our camera shows deep pitting through more than a third of the liner’s length, replacement is the better call because a patched liner fails again fast. We show you the camera footage so you can make that call with your own eyes. Call (914) 233-3156 to schedule a camera inspection; it’s included with our repair estimates.
Some Olympia Chimney parts, particularly older model cap assemblies and specific liner diameters, can take two to three weeks for delivery when ordered through the manufacturer. That’s one reason we keep a range of quality aftermarket and cross-compatible parts on the truck: a DuraFlex liner, a HeatShield patch, or a universal cap often solves the problem the same day. We’ll always give you the choice before ordering and explain what works and what doesn’t.
If the issue is a cracked crown or failed flashing, water keeps getting in, and Yonkers freeze-thaw cycles will turn a $400 flashing job into a $2,500 masonry rebuild inside a few winters. If it’s a damaged liner, you’re looking at a potential chimney fire or carbon monoxide leaking into the home. We never tell you to fix something that can safely wait. But when we say a repair matters, we’ll show you the photos that prove it. Call (914) 233-3156 and we’ll give you an honest read on your chimney without the sales pressure.
At least once per year if you burn wood, and once every two years if you use gas logs, per National Fire Protection Association guidance. Cory Mitchell’s rule for Yonkers homeowners is simple: if you can’t remember the last time someone looked inside the flue, it’s overdue. Call (914) 233-3156 to book a sweep and inspection.
