Olympia Chimney Chimney Liner & Rebuild Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

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 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.

Our Olympia Chimney Chimney Liner & Rebuild Process

  1. 1
    Call and schedule. A live person answers, 24 hours a day. We book a Level-2 inspection with video scan, usually within a few days - sooner if there’s an active leak or blockage.
  2. 2
    On-site diagnosis. Our technician runs a camera the full length of the flue, photographs every defect, and explains what you’re seeing in plain English. No jargon, no rush.
  3. 3
    Parts decision. If the job needs a liner replacement, we present OEM Olympia parts alongside quality aftermarket options from DuraFlex, HeatShield, or Gelco. We explain the warranty implications of each, and you choose. No upsell.
  4. 4
    The repair. Background-checked, uniformed techs complete most liner replacements and partial rebuilds in one visit. We protect your floors, work clean, and test everything before we pack up.
  5. 5
    Documentation and guarantee. You get the photos, a written condition report, and our 90-Day Done Right Promise in writing. If it’s not right, we make it right - no paperwork, no arguing.
  6. 6
    Follow-up. We call to confirm satisfaction, and we keep your inspection video on file for comparison next season.
