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 Cleaning & Sweep in Greenwich: What to Know First
Olympia Chimney cleaning and sweep services in Greenwich typically run $229 to $389 for a standard open-flue fireplace, and most jobs are completed in 60 to 90 minutes with a same-week appointment. We’re an independent Olympia Chimney service provider – not a manufacturer rep – so our only interest is what the camera shows in your flue, not pushing a particular product line. If you own an Olympia chimney or fireplace component in Greenwich and haven’t had it swept in over a year, this page tells you what to expect, what it costs, and what actually happens during a Level Two Chimney Greenwich visit. Call (516) 399-5497 for a written estimate before anyone touches a brush.
How Olympia Chimney Products Fail – and How We Fix Them
Greenwich homes show us the same Olympia Chimney failure patterns year after year. Here’s what we find and what we do about it:
- Olympia Ventis rigid liner perforation at the first flue tile offset. Older Olympia Ventis stainless liners in Greenwich colonials built in the 1980s and 90s develop pinhole rust at the bends, especially where the liner passes through the smoke chamber. This isn’t a cleaning issue alone – it’s a liner integrity issue. We camera-scan first, then recommend either HeatShield resurfacing or a DuraFlex liner replacement only if the footage warrants it. We’ll show you the photos either way.
- Cast-iron damper plate warping on Olympia masonry fireplaces. The damper sits directly above the firebox where heat cycles are hardest. Greenwich homes that burn wood three to four nights a week from October through March frequently warp the damper frame. We remove creosote buildup around the plate, test the open-close travel, and quote a replacement plate only when the warp prevents a full seal. If it still seals, we tell you it’s fine and leave it alone.
- Class III creosote glazing in Olympia unlined or partially lined chimneys. Greenwich backcountry and mid-country homes with older Olympia-built masonry flues collect hard, shiny creosote that standard brushes don’t remove. We use rotary chain whip heads and chemical treatments sized to your flue dimensions – it takes longer, which is why the price lands at the top of the range we quoted above.
- Olympia stainless cap screen clogging from maple and oak seed helicopters. Greenwich has dense maple coverage, and Olympia caps with fine mesh screens clog fast in spring. We remove the cap, clean the screen, and when we see an owner hasn’t had the chimney swept in two or more years, we point out that the clogged screen is a symptom of heavier creosote below. The fix is a full top-down sweep, not just a screen rinse.
- Crown spalling on Olympia chase-top installations. Olympia chimney systems with poured concrete crowns in Greenwich face freeze-thaw cycles every winter. Hairline cracks expand, water seeps in, and the crown spalls – chunks flake loose over time. During a sweep we photograph the crown condition as standard and quote a crown seal or rebuild as a separate line item. Nothing gets bundled into a surprise scope.
Our Olympia Chimney Chimney Cleaning & Sweep Process

- 1
Call or text and get a written scope before we dispatch. You tell us your fireplace type and roughly when it was last swept. We issue a written price and a named tech assignment before the truck rolls. Clause 1 of the Haven Standard is unmissable: it’s in writing before work starts.
- 2
We arrive, lay drop cloths, and run the Level 2 camera scan first. The camera goes down the flue before any brush does. It documents liner condition, creosote class, and any blockages in real time. You see the footage while it’s still live, not after we’ve had a chance to explain away what we found.
- 3
We match the cleaning method to what the camera showed. Light soot gets a standard wire brush pass. Hard glazing gets rotary treatment. If we spot a liner defect, we pause and tell you what it means before going further. No one cleans around a structural problem at Level Two.
- 4
We clean the smoke chamber, damper, firebox, and cap. Olympia-specific parts get checked against OEM specs. Where a quality aftermarket part does the same job for less, we say so and quote both.
- 5
We run the camera again after the sweep. You get before and after footage, plus written documentation of what was found, what was done, and what we recommend for the next 12 months.
- 6
You leave with the full record: photos, scope, warranty. Clause 4 of the Haven Standard requires this. It’s been our practice since 2009, and we’ve never skipped it.

AfterWhat Olympia Chimney Chimney Cleaning & Sweep Costs in Greenwich
Here’s where Greenwich pricing actually lands:
- Standard open-flue fireplace sweep (Level 1 visual + cleaning): $229 to $279
- Level 2 camera-scan inspection + full sweep: $329 to $389
- Heavy creosote removal (Class III glazing, rotary treatment): $450 to $550
- Cap removal, screen cleaning, and reinstall: $75 to $125 added to a sweep
- Smoke chamber parging or damper replacement: quoted separately after camera documentation
What moves the price: flue height (two-story Greenwich center hall colonials cost more than one-story ranches in Cos Cob), creosote severity, and whether an Olympia cap needs full removal. We quote flat before we start, and we hold that number. Estimate is free – there’s no charge to find out what a sweep costs for your specific Olympia system. Written price, no exceptions.
Why Greenwich Homeowners Call Level Two Chimney Greenwich for Olympia Chimney Work

Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings, and every single one came with a written price before work started and a documented record when it was done. Corrine Halstead runs our Greenwich team, and she’s the reason our write-ups read the way they do: named findings, plain terms, nothing softened. The 365-Day Done Right Promise backs everything, which means if the sweep wasn’t performed correctly, we return and make it right – no invoice, no debate. When an Olympia chimney needs more than a cleaning, we work across the full materials spectrum: DuraFlex liners, HeatShield resurfacing, and Gelco sealants, all sourced through Haven’s buying network to keep prices honest. You get the right fix, not the only fix we happen to stock. We’re independently owned and operated under the Haven Standard. Calls are answered by a live person, 24/7.
FAQs
Once per year if you burn wood more than twice a week during the season, and regardless of frequency, a camera-scan inspection is worth doing annually. Greenwich’s high-moisture winters accelerate creosote hardening, especially in older Olympia masonry flues. Call (516) 399-5497 if it’s been more than 18 months since your last sweep.
No. Regular professional sweeping is a condition of most chimney and liner warranties, not a violation. We clean to NFPA 211 standards and document every visit, which is exactly the record a warranty claim would need. If you’re mid-warranty and need the paperwork trail, we provide it without being asked.
The camera tells us and then we show you. Creosote buildup is a maintenance issue – a rotary sweep fixes it. A liner with perforation, rust-through, or a failed seam is structural, and no amount of brushing will change that. We don’t recommend liner replacement unless the footage shows something that warrants it. If the camera shows a clean liner and a heavy coating, you’re buying a sweep and nothing else.
Class III creosote is a hard, glossy, tar-like coating that standard chimney brushes slide right over. It’s a fire hazard because it’s concentrated fuel, and yes, it can be removed – but it requires rotary chain whips and chemical treatment, which is why it costs more than a standard sweep. The camera doesn’t guess. Neither do we.
We work from backcountry Greenwich estates to the older colonials near Cos Cob, Riverside, Old Greenwich, and Glenville. Our techs know the housing stock in each area, and we can usually have a crew to your door within three to five business days. Text or call for a written estimate.
