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 Liner & Rebuild in Rockville Centre: What to Know First
As an independent Olympia Chimney service provider, we install, repair, and rebuild Olympia Chimney liner systems in Rockville Centre homes, with most liner replacements and partial rebuilds completed in a single visit and pricing agreed before we start. A typical Olympia Chimney stainless steel liner replacement in Rockville Centre runs between $2,800 and $4,500 depending on flue height and diameter, while partial rebuilds involving the firebox or smoke chamber start around $3,200. We’re Hearthstone Chimney Co., and we’ve been working on chimneys in this area since 1984. If your Olympia Chimney liner is showing gaps, your draft has fallen off, or a previous installer used the wrong diameter for your heating appliance, call us at (631) 498-8835. We’ll send a technician with a camera, show you exactly what we’re seeing, and give you a plain-English verdict you can use to decide what to do next.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti flexible liners in the OFL series develop circumferential cracks at the flex points after 15 to 20 years of Rockville Centre’s freeze-thaw cycles. The titanium-stabilized alloy resists acid corrosion well, but the corrugations work-harden and split where the liner bends near the smoke shelf. We pull a new section with a smoother radius, or switch to a rigid 316Ti system in straight flues to eliminate the stress point entirely.
- Olympia Chimney’s ovalized flexible liners (OFL-OVAL) pancake in tall flues when installers skip the mandatory support spacing. We’ve found three in Rockville Centre where the oval profile collapsed to a slit, choking draft and dumping CO. We reinstall with proper support brackets every four feet and a top plate that carries weight without deforming the profile.
- The Olympia Chimney Ventis line, popular for gas conversions in 1990s split-levels near South Side High School, uses lighter-gauge metal that corrodes at the waterline where condensate pools in offset flues. We don’t patch these. We pull the Ventis and replace with a properly sized AL29-4C or 316Ti liner rated for the actual appliance, because a liner that fails once will fail again.
- Olympia Chimney’s masonry rebuild components, specifically their precast smoke chamber domes, separate from surrounding brick when the original installer used standard mortar instead of the specified refractory mix. The gap looks like a hairline from below but opens to an inch at the back. We remove the dome, re-bed it in HeatShield Cerfractory Foam or proper refractory mortar, and guarantee the bond won’t reopen.
- Olympia Chimney terra cotta flue adapters crack at the thimble connection when homeowners switch from oil to gas without resizing the liner. The adapter was sized for 250°F oil exhaust, not 120°F condensing gas. We replace the adapter with a properly engineered gas-rated top plate and reducer, and we document the appliance BTU input and vent category so the next tech knows what they’re looking at.
Our Olympia Chimney Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask about your appliance type, fuel, and what you’re noticing. No diagnostic by phone, but we can tell you if it sounds like a liner issue or masonry.
- 2
Level-2 camera inspection. Our technician runs a camera the full length of your Olympia Chimney flue, photographs every joint, crack, and deformation. You see the images on a tablet while we’re still on the ladder. We mark measurements for diameter, length, and offset angles.
- 3
Parts decision. If your Olympia Chimney liner is still under manufacturer warranty, we use OEM replacement sections and document the install per their requirements. If warranty has expired, we may recommend DuraFlex or Gelco components with equivalent or better specs, always with your approval in writing.
- 4
The repair. For liner work, we drop the new system, make top and bottom connections with proper support and sealant, and verify clearances to combustibles. For rebuilds, we lay refractory firebrick or pour HeatShield to factory specifications, not “close enough.”
- 5
Post-repair test. We run a smoke test or draft gauge check depending on the appliance, verify no spillage at the firebox, and photograph the completed work. You get the photos and a written report.
- 6
Cleanup and guarantee. We haul away debris, lay drop cloths back up, and leave the work area cleaner than we found it. The 90-Day Done Right Promise goes into effect in writing. If it needs doing, do it right the first time.
What Olympia Chimney Chimney Liner & Rebuild Costs in Rockville Centre

We don’t quote by phone for liner and rebuild work. Every flue is different, and “about three thousand” turns into four thousand fast when there’s a hidden offset. Our estimate is free, detailed, and fixed. The number on the estimate is the number on the invoice. Call (631) 498-8835 to schedule.
Why Rockville Centre Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been in Rockville Centre long enough to know which houses near South Side High School have the shallow fireboxes that fight draft, and which 1960s colonials on the north side have terra cotta flues too small for modern inserts. Russell Haines and our technicians carry that knowledge into every Olympia Chimney job.
Our Level-2 inspections end with photos you can see and a plain-English verdict. No hidden damage gets invented, and no necessary work gets buried in vague language. The 90-Day Done Right Promise means if it’s not right, we make it right, backed in writing with no paperwork and no arguing. We’re also fluent in DuraFlex, HeatShield, and Gelco systems, so if your Olympia Chimney components are discontinued or a different brand suits your flue better, we can make that call honestly.
A live person answers our phone 24 hours a day, 7 days a week. Our technicians are background-checked, uniformed, and complete most jobs in a single visit. We’ve been here over 42 years. We’ll be here when you need us again.
FAQs
No, as an independent Olympia Chimney service provider we follow manufacturer installation specifications and document our work so warranty coverage remains intact. We use OEM parts when warranty is active, and we record serial numbers and install dates in case you need them later. If your warranty has expired, we’ll explain equivalent aftermarket options and let you decide. Call (631) 498-8835 for specifics on your system.
Most Olympia Chimney liner replacements in Rockville Centre are completed in one day, with the crew arriving between 8 and 9 a.m. and finishing by late afternoon. Tall chimneys on three-story homes or flues with multiple offsets may require a second day. We tell you the expected duration in your written estimate so you can plan. Call (631) 498-8835 to check current scheduling.
We can repair isolated damage, a cracked top plate, or a failed adapter if the liner body is sound and the damage is accessible. We cannot safely patch cracks in the flex section itself or corrosion that has thinned the wall. The camera inspection shows which category you’re in, and we’ll tell you straight. Call (631) 498-8835 for a free camera inspection.
Most Olympia Chimney liner components remain available through distribution, though some Ventis-era adapters and early top terminals have been discontinued. We maintain relationships with multiple suppliers and can fabricate transitions or substitute DuraFlex or Gelco equivalents that meet or exceed original specs. We never start a job without confirming parts availability. Call (631) 498-8835 with your model information.
A sweep removes creosote and debris but does not fix cracked liners, missing mortar joints, or deteriorated flue walls. If your draft has dropped, you smell smoke in the house, or your heating technician flagged flue damage, you need Level-2 camera diagnostics before any sweep. We’ll show you the images and explain whether sweeping is safe or if liner work must come first. Call (631) 498-8835 to schedule.
