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.

AfterOlympia Chimney Chimney Liner & Rebuild in Woburn: What to Know First
We provide independent Olympia Chimney chimney liner and rebuild service in Woburn, with most jobs completed in a single visit and upfront pricing agreed before we start. A typical stainless steel liner replacement runs $2,800-$4,500 depending on flue height and configuration, and we stock the common Olympia Chimney diameters so we’re not waiting on freight. This page is for Woburn homeowners who already have an Olympia Chimney liner or factory-built chimney system showing signs of trouble - rust streaks, drafting problems, or a failed inspection - and want a crew that knows these parts without upselling what isn’t needed. Call (781) 404-3793 to speak with a live person, any hour.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti flexible liners in Woburn’s older Montvale Avenue capes often develop longitudinal seam separation after 15-20 years. The titanium-stabilized alloy resists acid corrosion better than basic 304, but the interlocked seam can work loose from thermal cycling in our freeze-thaw climate. We pull a camera to confirm the split location, then replace with a new 316Ti or upgrade to DuraFlex’s heavier-gauge equivalent if the flue run has offsets that stress the seam.
- Olympia Chimney’s Gelco-compatible rigid stainless systems sometimes suffer collar-to-liner joint failure where the appliance adapter meets the vertical run. The joint sees the most thermal shock, and Woburn basements with dehumidifiers running half the year create extra condensation at that low point. We cut back to sound metal, install a properly sleeved replacement collar, and verify the draft with a manometer before we leave.
- The Olympia Chimney smooth-wall round liners popular in 1990s Woburn splits can develop interior creosote glazing that standard brushing won’t touch. The slick surface was marketed as self-cleaning, but improper wood burning (green oak is common here) bakes a tar layer that reduces diameter and traps moisture against the metal. We use rotary poly chains to restore the bore, or replace if wall thickness has degraded.
- Olympia Chimney’s factory-built chimney chase enclosures in North Woburn frequently outlast the metal components inside. The galvanized chase cover rusts through at the corners, water saturates the framing, and the liner settles or separates at the thimble. We rebuild the chase with proper flashing, install a Gelco or Famco stainless cap, and reset or replace the liner with correct support spacing.
- Olympia Chimney’s oval-to-round adapter transitions are a known pinch point in tight Woburn flues where a full round liner won’t fit. The crimped transition can crack at the weld from expansion stress, especially in two-story homes with longer vertical runs. We fabricate a heavier-gauge replacement on-site or source an OEM adapter when available, and we always support the liner independently of the transition to isolate that stress.
Our Olympia Chimney Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, asks what you’re seeing, and books a Level-2 camera inspection. No deposit, no app to download.
- 2
Inspection and documentation. Our tech runs a camera the full flue length, photographs every defect, and explains what you’re looking at in plain English. You get the photos and a written verdict before any work is proposed.
- 3
Parts decision. If your Olympia Chimney component can be repaired with OEM parts, we quote that. If lead times are long or the OEM part has a known weakness, we explain the quality aftermarket alternative - DuraFlex, HeatShield, Gelco - and let you decide. No pressure either direction.
- 4
Repair with protection. We lay runners, mask the work area, and complete most liner replacements or rebuilds in one visit. Background-checked, uniformed techs; no subcontractors.
- 5
Testing and sign-off. We pressure-test or draft-test every liner installation, verify clearances to combustibles, and show you the results. The 90-Day Done Right Promise goes in writing before we pack up.
- 6
Cleanup and follow-up. We haul away old liner sections, run a magnet for debris, and leave the hearth cleaner than we found it. The invoice matches the estimate exactly.
What Olympia Chimney Chimney Liner & Rebuild Costs in Woburn
Pricing depends on flue height, access, and whether we’re working inside an existing chase or opening up finished space. These are real ranges from our Woburn jobs:
| Service | Typical Range |
|---|---|
| Olympia Chimney liner repair (patch, joint, or collar) | $450 - $950 |
| Partial liner replacement (single flue, standard height) | $1,800 - $2,800 |
| Full stainless liner replacement (Olympia Chimney or DuraFlex) | $2,800 - $4,500 |
| Chase rebuild with new liner and cap | $4,500 - $7,200 |
| Full chimney rebuild (above roofline, with liner) | $8,500 - $14,000 |
What moves the price: two-story flue runs, offset bends that require flexible liner instead of rigid, concealed damage to the chase framing we find during tear-out, and whether the appliance connection needs reworking. We quote the full number upfront, not a low opener with add-ons later. Call (781) 404-3793 for a free estimate - we’ll give you the real figure, not a sales pitch.
Why Woburn Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been in Woburn and the surrounding towns for over 42 years. Russell Haines and our crew know the Olympia Chimney systems installed in the building booms of the 1980s and 1990s because we’ve pulled failed ones out of homes from Montvale Avenue to North Woburn and explained to the owners exactly why they failed - no jargon, no panic. We carry DuraFlex, HeatShield, and Gelco in our trucks alongside Olympia Chimney-compatible parts, so we’re not leaving you without heat while we wait for a box to arrive. The 90-Day Done Right Promise is in writing: if it’s not right, we make it right, no paperwork and no arguing. If the flue isn’t right, the fire isn’t safe - and there’s no shortcut around that.
FAQs
As an independent Olympia Chimney service provider, we are not affiliated with or authorized by Olympia Chimney, so any remaining factory warranty on the original installation should be checked with your installer or Olympia Chimney directly. Our repairs use OEM or equivalent professional-grade parts and are covered by our own 90-Day Done Right Promise. Call (781) 404-3793 if you’d like us to review what warranty paperwork you have.
Most single-flue liner replacements are completed in one day, including removal of the old liner, installation, and testing. Jobs requiring chase rebuilds or masonry repair may run two days. We schedule for completion, not hourly billing, so the estimate covers the full job regardless of time. Call (781) 404-3793 to discuss your timeline.
We stock common Olympia Chimney diameters and adapters, and we source OEM parts when they make sense. When lead times are long or a known design weakness exists, we offer quality aftermarket alternatives from DuraFlex, HeatShield, or Gelco and explain the trade-off honestly. You decide. Call (781) 404-3793 to check availability for your specific model.
We won’t recommend replacement without camera evidence you can see for yourself. Some Olympia Chimney liners with isolated joint failure or minor corrosion can be repaired; others with generalized wall thinning or seam separation need replacement. We’ll show you the footage, explain both options, and tell you plainly if repair is a safe short-term fix or if replacement is the only sound path. Call (781) 404-3793 for a second opinion - it’s free.
Every year before burning season, per NFPA 211. Woburn’s freeze-thaw cycles and the acid condensation from modern efficient appliances stress liners harder than milder climates. An annual Level-2 inspection catches seam separation, corrosion, or creosote buildup before they become safety hazards. Our $89 Seasonal Tune-Up includes inspection and basic cleaning. Call (781) 404-3793 to schedule.
Ready to get your Olympia Chimney system checked? Call (781) 404-3793 now. A live person will answer, day or night, and we’ll schedule your free estimate at a time that works for you. No voicemail, no callback queue, no surprises on the bill - just the job done right, and we stand behind it.
