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 Flue Liner Replacement: The Worcester Owner’s Guide
We stock and install Olympia Chimney-compatible flue liner replacement in Worcester, with typical installed pricing running $2,800-$5,400 depending on flue height, diameter, and whether the clay liner is fully collapsed or cracked. Most Olympia Chimney liner jobs we book are completed in a single day, and we carry the common diameters on our trucks. Worcester owners usually discover the problem during a routine sweep when our camera finds cracked clay tiles, or when they notice bits of terracotta in the firebox after a heating season - that’s the liner shedding pieces, and it means combustion gases are hitting bare masonry.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures stainless steel flexible flue liners in 316Ti and AL29-4C alloys, sized from 3 to 12 inches in diameter. The critical detail is matching the alloy to your appliance: 316Ti handles wood and standard oil/gas, while AL29-4C is required for high-efficiency gas and pellet systems burning at lower flue temperatures. We’ve replaced Olympia liners in Worcester homes where the original installer used 316Ti on a condensing gas furnace - three years later the liner was perforated from acid corrosion.
To identify your liner, check the top termination for a stamped collar showing diameter and alloy grade, or have us run the camera and read the label from inside. If the collar is missing, we measure the flue and check the appliance BTU rating against Olympia’s spec chart. We source through Haven’s buying network, so we can quote OEM Olympia or a quality equivalent from DuraFlex or Gelco when the application allows - we’ll tell you which and why before you decide.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing

- Terracotta debris in the firebox or cleanout. Clay tile liners crack from thermal cycling, especially in Worcester’s freeze-thaw climate where chimneys on the north side of triple-deckers stay cold and heat unevenly. Those flakes are your liner’s structural integrity leaving.
- White or orange staining on exterior brick. This is efflorescence or acid wash from combustion condensate migrating through cracked tiles. In Main South’s original masonry, we’ve seen this track three courses down before the owner noticed anything inside.
- Smoke or odor seepage into upper floors. A compromised liner loses draft and pressurizes the chimney cavity. Gases find gaps at thimbles or through porous mortar - carbon monoxide risk, not just smell.
- Deteriorating mortar joints visible on camera. Even if tiles look intact, missing or sandy mortar between them lets heat reach combustible framing. NFPA 211 calls this an immediate hazard; we document it and stop the scan to show you.
- Your sweep recommends replacement every visit. If you’re patching cracks with HeatShield or similar resurfacing annually, the clay is fatigued. At some point the repair cost exceeds replacement, and we tell you when we’ve reached that point.

AfterReplacement Cost & What’s Included
| Component | Price Range |
|---|---|
| Olympia Chimney 316Ti liner (typical 25-30 ft, 6 in. diameter) | $1,400-$2,200 |
| Olympia Chimney AL29-4C liner (condensing gas/pellet) | $1,900-$3,100 |
| Labor: removal, installation, top plate, bottom connector | $1,200-$1,800 |
| Insulation wrap (required for NFPA 211 clearance reduction) | $200-$500 |
| Total installed, Worcester area | $2,800-$5,400 |
What drives the range: flue height (triple-deckers run 35+ feet), number of offsets or bends, whether we need to remove a damaged existing stainless liner first, and access - steep slate roofs in Worcester’s Vernon Hill or College Hill neighborhoods add rigging time. Every quote is written before work starts, with the scope, the warranty, and the final price. No change orders unless you add something. The 365-Day Done Right Promise applies, and materials carry manufacturer warranty through our Haven Standard procurement.
DIY or Call Us?

An owner can safely check for debris in the firebox or look up the flue with a flashlight for obvious tile gaps. Do not attempt to remove or install a flue liner yourself. The work involves working at height on a roof, handling sharp stainless edges, and properly sizing draft for the connected appliance - a liner that’s too large or uninsulated will condense acidic moisture and fail early, or worse, allow creosote buildup that ignites. We’ve been called to correct DIY liner jobs where the top plate was sealed with generic silicone instead of high-temp sealant, or where the liner terminated two feet short of the crown.
We carry common Olympia Chimney diameters on our trucks, and Corrine Halstead assigns a named technician who texts when en route. Call (978) 307-8288 for a written estimate - the camera inspection and photos are included, and the price doesn’t change after you approve it.
FAQs
A properly installed 316Ti liner typically lasts 15-25 years; AL29-4C often exceeds 20 years. Worcester’s freeze-thaw cycles and acidic condensate from high-efficiency appliances shorten that if the wrong alloy was chosen or if the liner wasn’t insulated. Annual inspection catches corrosion before it breaches the wall. Call (978) 307-8288 for an exact quote - estimates are free.
HeatShield and similar resurfacing products can seal minor cracks and gaps in otherwise sound clay, but they don’t restore structural integrity to tile that’s spalling or shifted. We camera-scan first and show you the footage - if more than 20% of the surface is compromised or any tile is missing, replacement is the only code-compliant fix. Call (978) 307-8288 for an exact quote - estimates are free.
Most Olympia Chimney liner replacements we complete in one day, start to finish: arrival, setup, camera confirmation of measurements, pull the old liner or break out clay, install and connect the new, top plate and rain cap, final camera verification. Complex offsets or two-story flues in Worcester’s older stock may run into a second day. We tell you which to expect in the written scope. Call (978) 307-8288 for an exact quote - estimates are free.
We stock 316Ti and AL29-4C in 5, 6, and 8 inch diameters on our trucks, which covers the majority of Worcester residential flues. Specialty sizes or 10+ inch diameters we pull next-day through Haven’s buying network from Olympia Chimney, DuraFlex, or Gelco depending on application and availability. Call (978) 307-8288 for an exact quote - estimates are free.
