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 Northport: What to Know First
We provide independent Olympia Chimney chimney liner & rebuild service in Northport, with most liner replacements and partial rebuilds completed in a single visit and priced upfront before any work begins. Typical Olympia Chimney stainless steel liner jobs run $2,800-$4,200 in this market, depending on flue count and accessibility, and we don’t recommend anything you can’t see for yourself on camera. This page is for Northport homeowners with an Olympia Chimney liner, cap, or component showing signs of failure, or for those told they need a full rebuild and want a second opinion backed by photos. Call (631) 528-2501 anytime - a live person answers, even at midnight on a Sunday.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia 316Ti flexible liner accordioning in tall Northport flues. The 316Ti series uses a lighter titanium alloy that saves on material cost but fatigues faster in vertical runs over 25 feet, which is common in the three-story colonials near Eatons Neck. We see the corrugations flatten or tear at stress points after 8-12 years. Our fix: we measure the full flue run with a video scan, then replace with a heavier-gauge DuraFlex or Gelco equivalent rated for the actual height, or step up to Olympia’s own 304L if the homeowner wants to stay OEM.
- Olympia Gelco-top chimney cap rust-through at the weld seam. The Gelco line’s galvanized base cap holds up fine inland, but the salt air coming off Northport Harbor accelerates corrosion at the factory weld, usually on the north-facing side. Water gets in, freezes, and spalls the crown below. We replace with a stainless Gelco upgrade or a Famco equivalent, then re-pour or seal the crown with HeatShield - never just slap a new cap on a rotten crown.
- Olympia HeatShield cerfractory flue resurfacing delaminating after improper prep. We’ve opened flues in Northport where a previous contractor sprayed HeatShield over glazed creosote or loose tile. It flakes off in sheets within two seasons. Our fix: mechanical cleaning to bare terra cotta, then a bond coat application per HeatShield’s actual spec, with a video-documented before-and-after. Russell Haines has done enough of these to spot bad prep from the first camera frame.
- Olympia rigid 304L liner separating at the collar joint in oil-conversion jobs. When Northport homeowners switch from oil to gas, the lower exhaust temperature changes how the rigid liner expands and contracts. Olympia’s collar joints, especially on pre-2015 stock, can work loose. We find the gap with a smoke test, then re-seat with a proper expansion joint or switch to a flexible liner if the flue has offsets the rigid can’t follow.
- Olympia chase cover sagging and pooling water on prefab chimneys. The stamped steel covers on older Olympia prefab systems weren’t built for the snow loads we get in Suffolk County. The center sags, water pools, and rusts through from the top down. We fabricate a custom Copperfield stainless chase cover with a proper diverter ridge, or source an Olympia OEM replacement if the chase dimensions match current stock.

FAQs
No - as an independent Olympia Chimney service provider, we use manufacturer-specified parts and practices that preserve any remaining OEM warranty. We document everything in case you need to file a claim. Call (631) 528-2501 if you want us to review your warranty status before we start.
We source genuine Olympia components when they’re the right choice and available, but we also carry professional-grade alternatives from DuraFlex, HeatShield, and Gelco that meet or exceed OEM spec. We explain the trade-off on warranty coverage and longevity, and you decide.
The camera tells the story. If the terra cotta flue is structurally sound with isolated spalling or minor cracking, HeatShield resurfacing or a flexible liner insert may solve it. If the clay is shattered, the mortar is missing between courses, or the chimney is leaning, you’re looking at a partial or full rebuild. We show you the footage and give you both options when they exist.
Most single-flue flexible liner replacements in Northport take four to six hours from setup to final smoke test. Two-flue systems or jobs with difficult roof access may run longer, but we complete most in a single visit. You’ll know the expected duration before we start.
Depends on what the camera shows. A minor crack in a liner can become a blocked flue or a chimney fire risk after another winter of freeze-thaw and creosote buildup. But if the defect is stable and you’re not using the fireplace, waiting may be reasonable. We tell you which category you’re in, never pressure you either way, and document our recommendation so you have it in writing. Call (631) 528-2501 for a free estimate - then you can decide with real information.
