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.

How Olympia Chimney Products Fail - and How We Fix Them
- OPW-36 and OPW-42 wood-burning inserts: The refractory panels in these units develop hairline cracking after 8-12 seasons of the freeze-thaw cycles common to Mount Vernon’s uninsulated exterior chimneys. The cracks don’t always mean replacement - we photograph every panel, measure crack width against Olympia’s service bulletin thresholds, and replace only what’s truly failed. When we do replace, we source OEM refractory or match with HeatShield panel systems rated for the OPW series burn chamber.
- ODV gas direct-vent fireplaces: The pilot assembly on early ODV units (pre-2015) is sensitive to voltage fluctuation, which is a real issue in parts of Mount Vernon with older electrical service. We see pilot dropouts that misdiagnose as valve failure. Our techs test millivolt output at the thermopile under load - not just open-circuit - and replace the pilot generator with an OEM Olympia part rather than the universal aftermarket kits that throw off flame-sensing reliability.
- Olympia Chimney flex liner systems in fireplace conversions: The 316Ti flex can work-harden at the offset where it transitions from vertical to the appliance connection, especially in Mount Vernon’s tight chimney flues common in 1920s construction. We cut back to sound metal and reinstall with a properly sized DuraFlex or Olympia OEM adapter, never splicing with a lesser grade that voids the remaining warranty.
- ODV damper assemblies: The cast-aluminum damper frames on ODV units corrode at the pivot pin when combustion condensate drains poorly - a design that assumes level installation, which isn’t what we find in settled Mount Vernon hearths. We bore out the pin bore, install a stainless bushing, and correct the drain path so it doesn’t happen again in three years.
- OPW firebox throat dampers: The galvanized cable and spiral spring mechanism binds with creosote glazing, particularly when homeowners burn unseasoned hardwood (we see a lot of oak that’s been “drying” six months in Mount Vernon backyards). We don’t just lubricate and leave - we remove the assembly, clean to bare metal, and replace the cable with a stainless steel version from Copperfield that outlasts the original.
Our Olympia Chimney Fireplace Services Process
- 1
Call and schedule: A live person answers, 24/7. We ask the model number if you have it, the symptoms, and whether you’ve got photos. We quote a service window, not a four-hour guess.
- 2
Arrival and setup: Our technician arrives in a marked van, uniformed, background-checked. We lay protection from the door to the hearth. We confirm the upfront price before touching tools.
- 3
Level-2 camera inspection: For any fireplace service beyond a basic sweep, we run a camera. You see the footage on a tablet. We explain what we’re seeing in plain English, with a verdict: needs repair now, can wait, or not a problem.
- 4
Parts decision: If your Olympia Chimney needs parts, we show you OEM versus quality aftermarket options - DuraFlex for liner work, HeatShield for refractory, Gelco for caps. We explain the warranty implications of each choice. You decide.
- 5
The repair and test: We complete the work, pressure-test gas connections, verify draft with a manometer, and run a full burn cycle. No shortcuts.
- 6
Documentation and guarantee: You get photos, a written report, and our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing.

FAQs
No - federal law (the Magnuson-Moss Warranty Act) prohibits manufacturers from voiding warranties solely because you chose an independent technician. We use OEM or equivalent-grade parts and document our work, so your warranty stays intact. If you have concerns, call us at (914) 246-5794 and we’ll walk you through what’s covered.
Common ODV and OPW parts are in our regional supply chain and arrive within 2-3 business days. Older or discontinued series may take 5-7 days. We stock critical wear items - pilot generators, gaskets, refractory panels - and when we can complete the job with a quality aftermarket equivalent from DuraFlex or HeatShield, we’ll offer that option to save you the wait.
Replacement makes sense when repair costs exceed 60% of a new unit and the existing efficiency is poor. For most Olympia Chimney units under 20 years, repair is the better value - these are solidly built appliances. We’ll give you a straight comparison after inspection, with camera evidence you can see. No replacement pitch unless the numbers actually work for you.
Gas units: annually, before heating season. Wood-burning inserts: every cord of wood burned, or annually minimum. In Mount Vernon, where many chimneys vent through exterior walls with more thermal stress than interior stacks, we recommend not skipping years. The $89 Seasonal Tune-Up catches problems before they become expensive.
Yes - we’ve converted dozens in Mount Vernon, typically to a direct-vent gas insert. The work involves liner evaluation, gas line routing, and proper venting. We inspect the existing flue with a camera first; if the chimney is unsound, we’ll tell you plainly before quoting conversion. Call (914) 246-5794 for a free estimate - we’ll assess whether your setup is suitable and what it would take.
