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.
Famco Chimney Liner & Rebuild in Waltham: What to Know First
We provide independent Famco chimney liner and rebuild service in Waltham, with most jobs completed in a single visit and upfront pricing agreed before we start. A typical Famco liner replacement runs between $2,800 and $4,500 depending on flue height and condition, and we back every job with our 90-Day Done Right Promise in writing.
This page is for Waltham homeowners who already have Famco chimney components installed and need honest answers about whether to repair or replace. You are not looking for a sales pitch. You want to know what is actually wrong, what it will cost, and whether the work can wait. We will tell you plainly. Call (781) 905-8338 to speak with a live person, any hour.
How Famco Products Fail - and How We Fix Them
- Famco 304 stainless single-wall liners in Waltham’s freeze-thaw climate. We see these in pre-1990 colonials near Main Street and the South Side, where the liner was retrofit during a conversion to gas insert or pellet stove. The 304 alloy handles dry heat well but corrodes faster when condensation sits in the flue, which happens every March and April in Waltham when outside temperatures swing forty degrees in a week. We replace with 316Ti or 316L flexible alloy, or switch to a Famco-compatible insulated system if the appliance calls for it.
- Famco rigid 316 stainless tee sections and collar joints. The factory tee on older Famco rigid runs can develop stress cracks at the collar weld after fifteen to twenty years, especially where the appliance connector enters at an angle. We spot this with our camera during Level-2 inspection. When the crack is localized, we fabricate a replacement section from matching-gauge 316 stainless rather than patching with inferior hardware-store fittings that void the remaining system integrity.
- Famco top-mount dampers integrated with concrete crowns. The damper frame is cast into the crown on some Famco rebuild jobs from the 2000s. When the crown spalls, the damper frame loosens and the liner below loses proper support. We have rebuilt these crowns with polymer-modified crown coat over a Famco-compatible frame, or separated the damper from the crown entirely when the frame is too far gone to trust.
- Famco flex liner pull-throughs with inadequate support spacing. Some Waltham installers in the 1990s ran Famco flex without the required support every six feet, especially in tall chimneys off Moody Street’s triple-deckers. The liner sags, creosote pools, and draft drops. We pull the old run, inspect the full flue with our camera, and reinstall to NFPA 211 support spacing using Famco-compatible top plates and support rings, or transition to DuraFlex or Olympia Chimney flex when the flue configuration demands a different bend radius.
- Famco chimney caps with integrated spark arrestors on oil-to-gas conversions. The original cap mesh is sized for oil soot, not the finer moisture-laden exhaust of a high-efficiency gas appliance. The mesh corrodes, the cap lifts in Waltham’s winter nor’easters, and water runs straight down the liner. We measure the existing flue and appliance output, then spec a Famco-compatible replacement cap or a Gelco cap with proper mesh sizing and stainless strap anchors.
Our Famco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We ask about your Famco component, the appliance type, and any symptoms you have noticed. We book a Level-2 camera inspection.
- 2
Inspection and documentation. Our technician arrives in uniform, runs a camera the full flue length, and photographs the crown, exterior brick, and appliance connection. You see the photos on site. We deliver a plain-English verdict: repair, replace, or monitor.
- 3
Parts decision. If Famco OEM is available and appropriate, we quote it. If lead time is excessive or the original spec is outdated, we quote quality aftermarket from DuraFlex, HeatShield, or Gelco that meets or exceeds the original rating. You choose before we order.
- 4
The repair. Most liner replacements and partial rebuilds finish in one day. We protect your floors, run the new system, and seal the crown or rebuild as quoted. No surprises on the bill.
- 5
Testing and sign-off. We pressure-test or smoke-test the new liner, verify draft with a manometer, and show you the final photos. You get a written report and our 90-Day Done Right Promise.
- 6
Cleanup and follow-up. We haul away debris. If the flue is clear and the crown is sound, you will not hear from me until next season. That is the goal.

Why Waltham Homeowners Call Hearthstone Chimney Co. for Famco Work
We are not a chain, and we are not a one-truck operator who might answer the phone next year. Hearthstone Chimney Co. has been in this area for over 42 years, and Russell Haines has spent the better part of two decades on Waltham roofs, including plenty of older colonials near the Moody Street corridor where the fireplaces are well-used and the flue liners tell stories.
Our technicians are background-checked, uniformed, and trained on Famco systems specifically, not just generic stainless flex. We carry DuraFlex, HeatShield, and Gelco as backup when Famco OEM is not the right fit. Every inspection ends with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing, with no arguing. A square deal, no surprises on the bill.
FAQs
Most Famco warranties on older installations have already expired, but if yours is still active, using non-Famco parts or an uncertified installer can void what remains. As an independent Famco service provider, we document every part source and installation detail so you have a record if a warranty question ever arises. Call (781) 905-8338 and we will check your install date against Famco’s coverage terms.
Most Famco liner replacements are completed in a single day, including removal of the old run, camera verification of the flue, and installation of the new system. Jobs requiring crown rebuild or extensive masonry add a second day. We tell you the timeline before we start, and we show up when we say.
Yes, for most lines, though some Famco rigid tee configurations from the 1990s are discontinued. When OEM is unavailable, we source compatible 316 stainless from Olympia Chimney or DuraFlex that matches the original pressure and temperature ratings. We never substitute builder-grade fittings.
Localized cracks, minor corrosion at the top plate, or a failed cap usually justify repair. Widespread pitting, multiple perforations, sagging unsupported flex, or a liner that has separated from the appliance connector means replacement. Our camera inspection shows you exactly which category you are in, and we will tell you plainly if the work can safely wait a season.
A damaged or missing liner allows heat, sparks, and combustion gases to reach combustible framing and living spaces. Carbon monoxide can leak into the home. In Waltham’s older housing stock, where balloon framing is common in pre-1950 builds, the risk of a wall or attic fire is real and specific. That said, we do not invent hazards your chimney does not have. Call (781) 905-8338 for a free inspection and an honest assessment of what your Famco system needs.
