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 Repair in New York City: What to Know First
We repair Olympia Chimney systems in New York City, and most jobs take one day on site. A standard mortar repointing job on an Olympia chimney in a typical NYC brownstone or prewar building runs $850 to $1,600 depending on access and how much masonry has failed. We’re an independent Olympia Chimney service provider, not a factory-authorized shop, which means we repair against what the flue camera actually shows, not a manufacturer script. If you own a home in New York City with Olympia Chimney components and you’re seeing spalling brick, deteriorated mortar joints, or water staining around the chimney, this page tells you what’s actually wrong and what it costs to fix. Call (980) 580-8641 and we’ll send a tech who will put a camera down the flue and show you the footage before quoting a single dollar.
How Olympia Chimney Products Fail, and How We Fix Them
- Olympia galvanized steel caps corroding at the seams. The Olympia standard galvanized cap is a perfectly serviceable product, but in New York City the combination of acid rain, soot from rooftop exhausts, and salt air off the harbor eats the seam welds within three to five years. We see it constantly in Riverdale and on the Upper West Side. The fix is almost always a stainless replacement, and we’ll show you the corrosion on camera before anything gets touched.
- Mortar failure at the bond line on Olympia clay flue liners. When Olympia clay liners are installed in older NYC chimneys, the bond between the original brick and the new mortar is where failure starts. Freeze-thaw cycles in boroughs like Queens and the Bronx push water into micro-gaps, and the joints spall out from the inside. We repoint those joints with a mortar matched to the existing mix, then apply a breathable water repellent so the repair doesn’t trap moisture.
- Olympia chase covers warping on prefab systems. The Olympia chase cover for prefabricated fireplaces is made from formed sheet metal, and after years of direct sun and snow load it warps. The corners lift, water gets under the flashing, and you get rust streaks down the sides. We straighten or replace the cover and address the flashing underneath, which is usually where the actual leak lives.
- Flashing failures where Olympia chimneys meet flat roofs. A lot of Olympia Chimney installations in New York City sit on flat or low-slope roofs, especially in new construction and gut renovations in neighborhoods like Greenpoint and Astoria. The base flashing is only as good as the roofer’s sealant, and that sealant gives out. We tear out and reflash with Copperfield or custom copper, not a tube of caulk.
- Spalling brick on Olympia chimney stacks. This is the one we see most in prewar buildings: the outer brick on Olympia chimney stacks absorbs water, freezes, and pops the face off, leaving a “scalloped” look. We cut out the failed brick, match it, relay it with the right lime-based mortar, and waterproof so the next freeze cycle doesn’t repeat the damage.
Our Olympia Chimney Chimney Repair Process

- 1
We answer the phone, ask about the symptom, and put a tech on the schedule. You’ll get a text when they’re on the way and a tech name before they arrive.
- 2
The tech does a Level 2 camera scan. We run the camera down the flue and record everything. You’ll see the footage on the tech’s screen, live, before any discussion of price. That means you’ll see the cracked tile, the spalled mortar, the rusted cap with your own eyes.
- 3
You get a written scope and a written price before any work begins. Not an estimate that changes. Not a “we’ll see what we find.” A line-by-line scope and a dollar figure, signed before a single brick is touched. That’s Haven Standard Clause 1.
- 4
We make the decision together on parts. OEM Olympia parts are available for some models, but in a lot of cases an aftermarket part from Copperfield or DuraFlex is built to the same or better spec and costs less. We show you the options with real numbers and let you pick.
- 5
The repair gets done, then the camera goes back down. We record the finished repair with the same camera, so you have before-and-after documentation. Clause 4 of the Haven Standard requires a photo record on every job, and we’ve run that practice continuously since 2009.
- 6
We walk you through what was done, hand you the written warranty, and you’re done. The 365-Day Done Right Promise applies to every job: if it’s not done right, we make it right.

AfterWhat Olympia Chimney Chimney Repair Costs in New York City
Here are real numbers for common Olympia Chimney scenarios in New York City, based on what we quote week to week:
- Mortar repointing on an Olympia chimney stack: $850 to $1,600
- Spalling brick repair and replacement: $1,200 to $2,400 depending on how many bricks and access
- Chimney waterproofing with breathable sealant: $600 to $1,000
- Flashing repair or replacement where the Olympia chimney meets the roof: $750 to $1,800
- Full chimney rebuild above the roofline: $4,500 to $9,500
- Tuckpointing on Olympia chimney brick: $900 to $1,800
What moves the price is access. A chimney on a flat roof in Brooklyn is cheaper to reach than one on a pitched slate roof in Riverdale that needs a ladder and a safety line. The condition of the underlying brick matters too. If the inner wythe is gone, we’re rebuilding, not repointing. Call (980) 580-8641 for a free estimate, and you’ll get a written price before anyone touches the chimney.
Why New York City Homeowners Call Emberly Chimney Cleaners for Olympia Chimney Work

Because we show you the problem before we quote the fix. Corrine Halstead, our owner, grew up in Inwood at the northern tip of Manhattan, where ignored chimneys were everywhere, and she still runs jobs the way she ran her first inspection: camera first, price second, and no recommendation you can’t see on screen yourself. The camera doesn’t soften what it finds. Neither do we. Every tech is background-checked and uniformed, and every visit ends with a documented photo record. We also carry DuraFlex, HeatShield, and Gelco materials, so if your Olympia system needs a liner or a HeatShield coating rather than a masonry repair, we handle that under the same written-price rule. The 365-Day Done Right Promise is in writing on every job, and if a competitor gives you a written estimate, we’ll give you a free second opinion. Since 2009, we’ve done 38,000-plus inspections and cleanings, and every single one started with a written price before any work began.
FAQs
In most cases, no. Masonry repairs like repointing, flashing, and waterproofing are outside the scope of an Olympia Chimney product warranty, and using a reputable independent contractor does not void coverage on the components themselves. We’ll document every repair with photos so you have a permanent record if a warranty claim ever comes up.
Some OEM parts are still available through distributor networks, but lead times run longer and prices are often higher than comparable aftermarket options. We stock and source aftermarket parts from Copperfield, DuraFlex, and Famco that meet or beat the original spec on most Olympia systems. We’ll lay out the OEM versus aftermarket numbers in writing before you decide.
Most masonry repairs take one day on site. A full rebuild above the roofline runs two to three days depending on weather and access. We don’t promise same-day dispatch for every call, but we schedule honestly and text you when the tech is on the way. Call (980) 580-8641 to get a date on the calendar.
If the masonry is failed but the flue liner is intact and the structure is sound, repair is the right call. If the liner is cracked, the chase is rusted through, or the stack is leaning, replacement starts to make sense. The camera scan tells us which one you actually need. We won’t recommend a rebuild we can’t show you on the footage.
Water keeps getting into the masonry, the freeze-thaw cycle keeps popping brick faces, and the damage spreads downward. Eventually the chimney leans, the flashing fails completely, and water reaches the interior framing. The repair bill goes from four figures to five. If you’re seeing signs now, call (980) 580-8641 and we’ll give you a written price before any work starts.
