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
- Olympia Chimney stainless steel liner corrosion in the condensing zone. The OLY-FLEX series, common in Mount Vernon homes with mid-efficiency furnaces venting into exterior chimneys, develops pinhole corrosion where flue gases cool below the dew point. We see this most in the Fleetwood and Chester Heights neighborhoods where long exterior runs stay cold. We replace with a properly sized DuraFlex or Gelco liner rated for the appliance, and we insulate the chase to keep gases above condensation temperature.
- OLY-RIGID liner seam separation after thermal cycling. The rigid stainless series uses a rolled-and-locked seam that can work open after years of daily heat-up and cool-down, especially when homeowners oversize fires. Our camera catches the gap before smoke leaks into the cavity. We pull the damaged section and install a new Olympia Chimney-compatible rigid run, or switch to a flexible liner if the flue has offsets that stress rigid joints.
- OLY-ALUM flexible liner delamination in oil flues. The aluminum core in older Olympia Chimney flexible liners degrades where sulfur-laden oil exhaust condenses. In Mount Vernon, where oil heat still serves many of the pre-war two-families near South Fourth Avenue, we find this every autumn. We do not patch aluminum - we replace with a 316Ti stainless flexible liner from DuraFlex or Gelco, sized to the appliance’s net flue area per NFPA 211.
- Clay flue tile collapse behind an Olympia Chimney liner. Homeowners sometimes install a liner without addressing spalled clay tiles above or below it. The liner then bears weight it was never meant to carry, and we find it ovalized or torn at the shoulder. We remove the liner, rebuild the clay section with proper clearance, and reinstall - or convert to a full HeatShield cerfractory flue seal if the damage is scattered but the structure is sound.
- Olympia Chimney connector pipe failure at the thimble. The OEM connector pipe, especially on older OLY-FLEX installations, can rust through where it passes the masonry thimble. Moisture from a leaking crown accelerates this. We replace the connector with a Famco or Copperfield equivalent, rebuild the thimble with proper pitch, and seal the crown so the repair outlasts the warranty.
Our Olympia Chimney Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24/7. We book your Level-2 inspection, usually within a few days during sweep season.
- 2
Camera inspection and documentation. Our technician runs a video scan of the full flue length. You see the footage. We mark timestamps of damage and explain what’s happening in plain English - no jargon, no scare tactics.
- 3
Parts decision: OEM or quality aftermarket. We stock Olympia Chimney-compatible liners and components, but we’ll also quote DuraFlex, Gelco, or HeatShield if the application calls for it. We explain the trade-off - warranty coverage, material grade, longevity - and you choose.
- 4
The repair. Background-checked, uniformed technicians complete most liner replacements and partial rebuilds in one visit. For a full chimney rebuild, we stage materials and return to finish without dragging the job across weekends.
- 5
Post-repair test and photo report. We run a smoke or draft test, verify clearances, and give you dated photos of the completed work plus a written summary.
- 6
The 90-Day Done Right Promise. If anything’s not right, we come back. In writing. No arguing. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.

Why Mount Vernon Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been answering the phone with a live person for over 42 years. Russell Haines, our owner, learned this trade at Los Angeles Trade-Technical College and has spent the better part of two decades working chimneys across Westchester. His crew knows the older two-families near Fleetwood - the long flue runs, the oil-to-gas conversions, the chimneys that were never quite right after a 1980s renovation. We document every inspection with photos you can see and a plain-English verdict. We work with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. And we back every job with the 90-Day Done Right Promise in writing. If it needs doing, we’ll tell you. If it doesn’t, we’ll tell you that too.
FAQs
No - as an independent Olympia Chimney service provider, we use OEM-compatible parts and document our work to manufacturer standards. The warranty covers material defects, not who installed it, provided the installation meets code. If you have concerns, we’ll review your paperwork before we start. Call (914) 246-5794 and we’ll walk through it.
We stock common Olympia Chimney liner diameters and fittings, and our supply chain covers Westchester with next-day availability on most specialty items. In twenty years of local work, we’ve never lost a season to parts delay. Most jobs start and finish the same day we inspect.
The camera tells the story. Localized gaps or minor corrosion in an otherwise sound liner often qualify for HeatShield cerfractory sealing or a partial section replacement. Widespread thinning, multiple seam failures, or delamination mean replacement is the honest call. We show you the footage and explain both options with prices. No pressure either way.
A compromised liner lets heat and combustion gases reach combustible framing - the leading cause of chimney fires. In Mount Vernon’s older housing stock, where balloon framing is common in pre-1940s builds, that risk is not theoretical. Carbon monoxide infiltration is the other concern, especially with a deteriorating oil flue. We don’t use scare tactics, but we don’t soft-pedal facts either. If the camera shows a hazard, we’ll say so plainly.
Yes - a permanent 5% discount for seniors and veterans, applied to any liner or rebuild service. We also offer $50 off any repair over $250, a free second opinion on any written estimate, and an $89 seasonal tune-up. Only one promotion per job, and we’ll apply whichever saves you more. Call (914) 246-5794 for details.
