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 Chelmsford: What to Know First
We provide independent Olympia Chimney chimney liner and rebuild service in Chelmsford, with most liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. A typical Olympia Chimney stainless steel liner replacement runs $2,800-$4,200 in this market, and we quote that number upfront - no surprises on the invoice. If you own an Olympia Chimney liner system and suspect creosote buildup, drafting problems, or visible flue damage, we’ll document what we find with photos you can see and give you a plain-English verdict on whether repair or replacement makes sense. Call (978) 991-9492 - a live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti flexible liner, premature seam separation. The 316Ti alloy handles Chelmsford’s freeze-thaw cycles well, but we’ve found that early-production runs from 2015-2018 had inconsistent weld penetration at the corrugation seams. In homes near Heart Pond with longer lateral runs, condensation pools at low points and those weak seams open. We cut back to sound metal, splice in a new Olympia-compatible section, and verify with a pull-through camera before we close up.
- Olympia Chimney rigid stainless tee assemblies, draft collar cracks. The cast draft collars on Olympia’s rigid tee systems can work-harden after a decade of thermal cycling, especially when homeowners run their stoves hot through January cold snaps. Hairline cracks don’t always show from the firebox side. We spot them during camera inspection, source the matching tee from our Olympia parts stock or fabricate a transition to DuraFlex rigid if Olympia lead times stretch out.
- Olympia Chimney smooth-wall liners, mortar joint washout in unlined chimneys. When an Olympia smooth-wall liner is retrofit into a Chelmsford colonial with no original clay liner, the gap between liner and masonry traps moisture from our wet springs. Over time, the old mortar behind it turns to sand. We pull the liner, repoint the wythe with HeatShield-compatible refractory mortar, and reinstall with proper insulation wrap - not the shortcut of stuffing fiberglass.
- Olympia Chimney oval-to-round adapters, creosote bridging. The geometry change in these adapters creates a velocity drop that heavy Appalachian-bituminous coal users around Chelmsford know too well. Creosote bridges across the adapter throat, restricting draft and accelerating corrosion. We replace with a custom-fabricated gradual transition in 304 or 316 stainless, depending on fuel type, and pitch it correctly so condensate runs back to the appliance.
- Olympia Chimney top-mounted termination caps, spark arrestor mesh failure. The woven mesh on earlier Olympia caps fatigues at the weld points, dropping embers onto cedar-shake roofs still common in the West Chelmsford historic district. We upgrade to a Gelco or Famco cap with a heavier gauge screen and proper overhang, matched to the liner diameter so it doesn’t whistle in a nor’easter.
Our Olympia Chimney Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We book your Level-2 inspection, usually within a week during sweep season.
- 2
Camera inspection and documentation. Our technician runs a chimney camera from top to bottom, capturing video and stills of every joint, seam, and transition. You see the same images we see.
- 3
Parts decision - OEM or quality aftermarket. If your Olympia Chimney part is in stock or readily available, we quote it. If lead times run long, we explain the DuraFlex, HeatShield, or Gelco equivalent and why it meets or exceeds the original spec. You decide.
- 4
The repair. Background-checked, uniformed techs complete most liner replacements and partial rebuilds in one visit. We protect your floors, contain dust, and work methodically - no rushing the mortar cure, no forcing a liner past an offset that needs addressing first.
- 5
Smoke test and final documentation. We pressure-test or smoke-test every liner installation per NFPA 211, then provide photos of the completed work and a written condition report for your records.
- 6
The 90-Day Done Right Promise. If it’s not right, we make it right. In writing. No arguing. That’s the Keystone Standard.
What Olympia Chimney Chimney Liner & Rebuild Costs in Chelmsford
These are real numbers for Chelmsford homes we’ve worked on, not teaser rates that balloon on the invoice:
| Olympia Chimney flexible liner replacement (single flue, standard height) | $2,800 - $4,200 |
| Olympia Chimney rigid liner replacement with tee assembly | $3,500 - $5,500 |
| Partial chimney rebuild (above roofline, with Olympia liner reinstall) | $4,500 - $7,500 |
| Full chimney rebuild with new Olympia-compatible liner system | $8,500 - $14,000 |
| Olympia liner repair (sectional splice, minor seam weld) | $850 - $1,600 |
What moves the price: chimney height, accessibility (steep roofs cost more to stage), whether the existing liner is cemented in place, and if the clay thimble needs rebuilding. We price these items separately so you see where your money goes. Call (978) 991-9492 for an exact quote - estimates are free.
Why Chelmsford Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Chelmsford in thirty more. That changes how you treat a customer.

Every inspection ends with photos you can see and a plain-English verdict. Every job carries the 90-Day Done Right Promise in writing. No surprises on the bill. If the flue isn’t right, the fire isn’t safe - it’s that simple.
FAQs
No, proper chimney rebuild work done by a qualified professional does not void your Olympia Chimney liner warranty, provided the liner is reinstalled according to manufacturer clearances and the rebuild doesn’t alter the flue path dimensions. As an independent Olympia Chimney service provider, we document our installation with photos and measurements so any future warranty claim has support. Call (978) 991-9492 if you need warranty documentation assistance.
Most Olympia Chimney liner replacements are completed in one day, though full chimney rebuilds with liner reinstall typically run two to three days to allow proper mortar curing between lifts. We don’t rush the cure - sloppy mortar work is a chimney fire waiting to happen. We’ll give you a firm schedule when we quote.
We repair Olympia Chimney liners when the damage is localized - a separated seam, a cracked tee, a damaged section we can splice. We recommend full replacement when corrosion is generalized, when multiple seams are failing, or when the liner diameter is wrong for the appliance and causing chronic creosote buildup. Our camera inspection shows you which category you’re in.
We stock common Olympia Chimney fittings and adapters, and we maintain relationships with distributors for faster turnaround on special-order items. When Olympia parts are back-ordered, we explain the DuraFlex, HeatShield, or Gelco equivalent and let you choose. We don’t leave you guessing about timelines.
NFPA 211 calls for annual inspection of all chimney systems, and Chelmsford’s wet springs and heavy heating-season use make that especially sensible for Olympia Chimney liners. If you burn cordwood, we also recommend sweeping when creosote reaches 1/8 inch. Catching liner problems early is what Russell Haines is known for around here - the kind that don’t announce themselves until it’s too late. Call (978) 991-9492 to schedule.
