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.

AfterFamco Chimney Liner & Rebuild in Cambridge: What to Know First
We provide independent Famco chimney liner and rebuild service in Cambridge, with most liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. As an independent Famco service provider, we carry OEM and quality aftermarket parts for the Famco lines most common in this market, and we quote every job upfront so the number on the estimate matches the number on the invoice. If your Famco liner is showing gaps, your flue gases are not venting safely, and that is not a situation that improves with waiting. Cambridge homeowners with older brick-stack homes, particularly around Harvard Square, Porter Square, and the Brattle Street corridor, have been calling us about Famco liner issues for years. We are Hearthstone Chimney Co., and we have been doing this work since 1984. Call (857) 392-4709 for a free estimate.
How Famco Products Fail - and How We Fix Them
- Famco SL Series stainless liners: The SL Series flex liner was specified heavily in Cambridge’s 1990s-era gas conversions, and we see the same failure pattern repeatedly. The 316-grade inner wall develops pinpoint corrosion where condensate pools at the lower flue joint, especially in homes without proper chimney caps. We replace with a matching Famco SL or, more often, upgrade to a DuraFlex Pro equivalent with better condensate drainage geometry.
- Famco rigid 304-to-316 transition joints: The transition collar where 304-grade meets 316-grade in older Famco rigid systems is a known thermal stress point. Cambridge’s freeze-thaw cycles accelerate the fatigue, and we have found cracked welds at this joint in twelve homes along Brattle Street alone. We cut back to sound metal and fabricate a proper 316-alloy splice, or replace the full section if the damage extends.
- Famco HeatFab Saf-T Liner in parged clay flues: The Saf-T Liner’s ribbed profile was designed to center in unlined chimneys, but the parging mortar behind it degrades faster than the liner itself in Cambridge’s saturated winters. We pull the liner, re-parge with HeatShield Cerfractory Foam where the substrate allows, or recommend a partial rebuild if the clay tile is too far gone to support new parging.
- Famco top plate and storm collar assemblies: The stamped-steel top plates on Famco’s economy liner kits flatten and lose seal after fifteen to twenty years of snow load and UV exposure. Water tracks down the flue and pools behind the liner, rusting the connector from the inside. We replace with Gelco or Olympia Chimney stainless top assemblies with reinforced shoulders, and we document the before condition with photos you can see.
- Famco flexible liner over-pull in tall Cambridge stacks: Famco’s flex liner installation specs allow for a certain stretch percentage, but in Cambridge’s forty-foot-plus triple-decker chimneys, installers often pull too tight to avoid an extra section. The liner bellies slightly, collects condensate, and rots from the bottom. We measure with a laser on every job and order the correct section count rather than forcing a fit.
Our Famco Chimney Liner & Rebuild Process

Call and schedule: A live person answers, 24 hours a day. We book a Level-2 camera inspection with no deposit.

Parts decision: We check Famco OEM availability against DuraFlex, HeatShield, or Gelco equivalents. We explain the trade-off, warranty implications, and price difference. You decide.
- 4
Repair or rebuild: Our background-checked, uniformed technician completes most Famco liner replacements and partial rebuilds in a single visit. Full rebuilds may need a second day for cure time.
- 5
Test and verify: We pressure-test or smoke-test every liner installation, run the camera again to confirm proper seating, and show you the after photos.
- 6
Guarantee in writing: The 90-Day Done Right Promise covers the work. If it is not right, we come back. No paperwork, no arguing.
What Famco Chimney Liner & Rebuild Costs in Cambridge
These are real ranges for Famco-specific work we have performed in Cambridge within the past eighteen months. Your exact quote depends on flue height, accessibility, and whether we can reuse the existing top assembly.

|---|---|---|
| Famco flex liner replacement (single flue, standard height) | $2,800 - $4,200 | Flue length over 25 ft; need for new top plate |
| Famco rigid liner section repair / splice | $1,400 - $2,600 | Number of damaged joints; welding vs. replacement |
| Partial chimney rebuild with Famco liner replacement | $5,500 - $9,000 | Courses of brick to replace; crown condition; scaffolding |
| Full chimney rebuild with new Famco or DuraFlex liner | $12,000 - $18,000 | Height; matching historic brick; interior demolition |
| Famco top plate / storm collar replacement only | $650 - $1,100 | Flue diameter; access difficulty |
We do not recommend work without camera evidence you can see for yourself, and we will tell you plainly when a repair can safely wait another season. Call (857) 392-4709 for an exact quote. Estimates are free.
Why Cambridge Homeowners Call Hearthstone Chimney Co. for Famco Work
We are not the cheapest option in Cambridge, and we do not try to be. We are the option for homeowners who have already been told they need a full rebuild by someone who did not run a camera, or who watched a previous liner fail in six years because the installer used builder-grade materials and pulled it too tight.
Our 90-Day Done Right Promise is in writing with no arguing. Our technicians are background-checked, uniformed, and trained on Famco’s specific connection geometry, not generic liner installation. We stock Famco, DuraFlex, HeatShield, and Gelco parts so we are not ordering blind and making you wait. And when Russell reviews your inspection photos, he is looking at the same kind of chimney he has been climbing in Cambridge for years, including those older brick-stack homes along Brattle Street that have a way of humbling even an experienced sweep.
If it needs doing, we will tell you. If it does not, we will tell you that too.
FAQs
Famco’s limited warranty covers manufacturing defects regardless of who installs, but installation errors are not covered. We document every Famco job with photos and a written report so any future warranty claim has clear evidence the work was performed to spec. As an independent Famco service provider, we keep installation records for ten years. Call (857) 392-4709 if you need help with a warranty submission.
Yes, for most lines produced after 1995. Famco discontinued its 1980s rigid coupler style, but we fabricate compatible transitions from 316-alloy stock or source DuraFlex equivalents that mate correctly. We verify parts availability before we quote, not after we start.
A repair is viable when damage is localized to one joint or section and the remaining liner shows no wall thinning or deformation. Full replacement is necessary when corrosion is generalized, when the liner has separated from the top plate, or when multiple patch points would create more failure points than a new system. Our camera inspection shows you exactly which category you are in. Call (857) 392-4709 to schedule.
Most single-flue Famco liner replacements in Cambridge are completed in four to six hours. Partial rebuilds add a day for mortar cure. Full rebuilds typically run two to three days. We give you a specific timeline with your upfront quote.
A damaged liner allows flue gases, including carbon monoxide, to leak into wall cavities and living spaces. In Cambridge’s tight triple-decker construction, that migration happens faster than in detached homes. Creosote can also reach combustible framing if the liner gap is below the roofline. The risk is real, but we do not scare-sell. We show you the camera evidence and let you decide on your timeline.
