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 collars loosen in freeze-thaw cycles. The 316Ti flexible liner series uses a compression-fit collar design that works well in mild climates, but Mount Vernon’s freeze-thaw swings from January through March gradually back out the seam. We find gaps at the thimble connection in about one of every four Mount Vernon inspections. Our fix: remove the collar, reseat with a proper high-temp sealant rated to 2100°F, and add a mechanical lock ring where clearance allows. Done right, it outlasts the original install.
- Olympia Chimney Gelco-compatible caps corrode at the weld seam near salt air. The GC-series cap with the standard mill finish holds up poorly within ten miles of Long Island Sound - Mount Vernon sits right at that edge. We see pinhole rust at the corner welds after six to eight years, not the fifteen the spec sheet suggests. We source the same cap in 304 stainless with a powder coat from our Gelco supply, or step up to a copper version if the homeowner plans to stay put. Either way, we document the before and after.
- Olympia Chimney HeatShield-compatible refractory panels crack from rapid temperature swings. The factory panels in their factory-built fireplace line thin out faster in Mount Vernon homes where owners run intermittent fires - weekend-only use, then nothing for two weeks. Thermal shock does more damage than steady burning. We remove the damaged panel, cast a new HeatShield cerfractory mix in place, and cure it to factory spec. The repair carries the same 20-year warranty as a full replacement, at about half the cost.
- Olympia Chimney DuraFlex-compatible relining jobs fail at the offset. Their ProFlex series handles straight runs well, but Mount Vernon’s older colonials and two-families often have a thirty-degree offset above the smoke shelf. The ProFlex armor tears at the flex point after three to five years if the installer didn’t account for tension. We measure the offset with a laser and specify DuraFlex’s heavy-wall AL29-4C for anything over fifteen degrees. No guesswork, no callback.
- Olympia Chimney crown wash separates from the brick in south-facing exposures. The factory slurry crown on their masonry chimney line cures hard but brittle; Mount Vernon summers bake the south face while winter nor’easters saturate it. We see horizontal cracking at the brick interface by year seven. Our fix: grind back to sound concrete, apply a bonding agent, and pour a new crown with integrated drip edge and expansion joints. We use Copperfield’s crown mix, which we have found handles the thermal cycling better than the original formulation.
Our Olympia Chimney Chimney Repair Process
- 1
Call and schedule. A live person answers, day or night. We book a two-hour window that we keep. Russell Haines or one of our senior techs confirms the Olympia Chimney model if you know it - the data plate is usually visible from the firebox or cleanout.
- 2
Level-2 camera inspection. We run a chimney camera from top to bottom and from bottom to top. You see the footage on a tablet in real time. We mark every defect with a timestamp and explain what we’re looking at in plain English - no jargon, no scare tactics.
- 3
Parts decision: OEM or quality aftermarket. For Olympia Chimney repairs, we source direct-fit OEM when the warranty is still active and the part is available. When OEM is backordered (their 316Ti flex liner components often are, eight to twelve weeks), we spec equivalent from DuraFlex, HeatShield, or Gelco - never builder-grade substitutes. We explain the trade-off and you decide.
- 4
The repair, documented. Our background-checked, uniformed techs work with drop cloths, HEPA vacuums, and the right tools for the job. Most repairs finish in four to six hours. We photograph every critical step - mortar depth, liner connection, cap fit - and save it to your file.
- 5
Post-repair test and walkthrough. We run a smoke test or draft test, depending on the repair. You sign off only when you’re satisfied. The 90-Day Done Right Promise goes in writing before we leave: Krafted right, Every time, Your home first, Standing behind it.
- 6
Cleanup and follow-up. We haul away debris and sweep the work area. A printed invoice matches the upfront estimate exactly. We call in thirty days to check that everything is performing as expected - not a survey, just a human checking in.

FAQs
No, independent repair by a qualified chimney professional does not void your Olympia Chimney warranty, provided we use OEM or equivalent-spec parts and follow NFPA 211 standards. As an independent Olympia Chimney service provider, we document every part source and installation detail so your warranty stays intact. If your unit is still under factory warranty, we flag that during inspection and source direct-fit OEM first. Call (914) 246-5794 and we’ll check your coverage.
OEM parts from Olympia Chimney typically ship in eight to twelve weeks for liner collars, caps, and specialty refractory pieces. We keep DuraFlex, HeatShield, and Gelco equivalents in stock for common sizes, so most repairs don’t wait. If you need an exact OEM match for warranty reasons, we order immediately and schedule the repair for arrival. You’ll know the timeline before we start - no surprises.
Most Olympia Chimney systems we see in Mount Vernon are repairable. Full replacement becomes necessary when the flue liner is perforated in multiple sections, the masonry shell is structurally compromised, or the firebox has cracked through to the outer shell. Our camera inspection shows you exactly what we’re seeing. If it needs doing, we’ll tell you. If it doesn’t, we’ll tell you that too. Call for a free second opinion if another sweep recommended replacement.
Every twelve months if you burn regularly, and after any chimney fire or seismic event. Mount Vernon’s freeze-thaw cycles and occasional ice damming accelerate mortar and crown deterioration, so we recommend a Level-2 inspection before the burning season each year. Catching a loose liner collar or cracked crown early saves the cost of water damage or liner replacement down the line. Our $89 Seasonal Tune-Up includes the inspection and a sweep if needed.
Small problems become expensive problems. A separated crown wash lets water into the flue, which rusts the liner and rots adjacent framing. A loose liner collar can leak carbon monoxide or allow creosote to build in the gap. Spalling brick weakens the structure and can lead to partial collapse in a hard freeze. None of this happens overnight, which is why we photograph and explain what we find. Some repairs can wait a season; others shouldn’t. We’ll give you a straight answer either way. Call (914) 246-5794 for a free estimate - no pressure, just facts.
