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.

How Famco Products Fail - and How We Fix Them
- Famco FV-Series gas fireplaces: intermittent pilot failure. The FV-36 and FV-42 units common in 1990s Chelmsford split-levels use a standing pilot assembly that collects condensation from our freeze-thaw cycles. The pilot orifice narrows, the flame lifts, and the main burner won’t catch. We clean the pilot assembly with regulated air pressure - never a wire brush, which widens the orifice - and replace the thermopile if millivolt output drops below 325 mV. If the pilot tube is cracked from age, we source OEM Famco spec or use a certified crossover from Copperfield.
- Famco wood-burning fireboxes: rear wall heat shield separation. The Famco Hearthmaster line installed in Chelmsford colonials near Heart Pond used a refractory panel system that shrinks differently than the steel wrapper. After fifteen winters, the air gap collapses and the back wall cracks. We remove the damaged panels, measure the gap with a feeler gauge, and reinstall with HeatShield cerfractory mix or replace with Gelco-compatible panels if the original Famco refractory is discontinued.
- Famco fireplace inserts: blower motor bearing seizure. The FB-Insert series from the early 2000s has a blower mounted beneath the firebox that ingests ash and pet hair. Bearings dry out, the motor hums, and the thermal overload trips. We pull the blower assembly, test amp draw against the Famco spec plate, and replace with an OEM-equivalent from Olympia Chimney Supply - same CFM, same mounting pattern, without the Famco markup when the part is available aftermarket.
- Famco dampers: corrosion weld in the throat. Famco’s cast-iron throat dampers in pre-1985 Chelmsford homes seize when creosote mixes with rainwater from a missing cap. The handle spins free but the plate won’t pivot. We access from the firebox when possible, free the pivot pin with penetrating oil and patience, and replace the assembly with a Gelco top-sealing damper if the throat is too damaged for reliable operation.
- Famco direct-vent terminals: wind-driven recirculation. The Famco DV-terminators with horizontal termination in Chelmsford’s exposed lots - especially west of Route 3 where winter winds run hard - can pull exhaust back into the intake. The flame pattern yellows, sooting accelerates, and CO risk rises. We inspect the vent balance with a manometer, relocate the termination vertically when site conditions allow, or install a wind-resistant cap from DuraFlex that maintains the Famco-specified 3-inch clearance.
Our Famco Fireplace Services Process
- 1
Call and schedule. A live person answers, day or night. We ask the Famco model if you know it, the symptoms, and whether the unit is gas or wood. We book a arrival window and email a confirmation.
- 2
Arrival and protection. Our technician arrives in uniform, lays drop cloths, and runs a Level-2 camera inspection of the flue and firebox. You see the photos on a tablet as we take them.
- 3
Diagnosis and plain-English verdict. We explain what’s wrong, what caused it, and what happens if you wait. For Famco units, we note whether the part is still manufactured, available aftermarket, or requires fabrication.
- 4
Upfront pricing and approval. We give one number. That’s the number on the invoice. No trip charges added, no “while we’re here” surprises.
- 5
Repair and testing. We complete the work, run the unit through a full cycle, check gas pressure or draft with calibrated instruments, and photograph the finished condition.
- 6
Cleanup, documentation, and guarantee. We leave the work area cleaner than we found it. You get a written report with photos, the 90-Day Done Right Promise, and our direct line if anything feels off.

Why Chelmsford Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve been in Chelmsford long enough to know which Famco models the builders installed in which subdivisions. Russell Haines and our crew have serviced Famco units in the older colonials near Heart Pond where narrow, offset flues test every sweep’s patience - and we’ve learned that patience is cheaper than a callback.
Our 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing. We use professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - never a substitute that saves us money and costs you later. Most jobs finish in one visit. The price we quote is the price you pay. And when you call (978) 991-9492, a live person answers, every hour of every day.
FAQs
No - as an independent Famco service provider, our work does not void any existing manufacturer warranty, provided we use parts that meet or exceed Famco specifications. We document everything we install so you have a record if a warranty question ever arises. Call (978) 991-9492 if you’d like us to review your warranty status before we start.
Many Famco parts are available through our supply network, including aftermarket equivalents from Olympia Chimney and Copperfield that match OEM specs. For discontinued lines like the early Hearthmaster refractory panels, we fabricate solutions with HeatShield or Gelco-compatible materials that perform as well or better. We’ll tell you honestly if a part is unobtainable before we book the job.
Replace when the firebox is cracked through to the wrapper, the flue is unlined and unsalvageable, or repair costs exceed 60% of a new unit installed. Repair when the issue is localized - a failed gas valve, damaged refractory, or stuck damper - and the chassis is sound. We’ll show you the camera evidence and give you both numbers so you decide. Call (978) 991-9492 for a free estimate.
Gas Famco fireplaces need annual inspection and cleaning of the burner, pilot, and venting. Wood-burning Famco units need sweeping when creosote reaches 1/8-inch thickness, typically once per cord of wood burned. Chelmsford’s cold-start winters - long idle periods followed by heavy use - accelerate wear on both types. We recommend preseason service, ideally by October, before the first sustained burn.
Gas units accumulate debris that blocks the pilot orifice and causes rollout, a fire and CO hazard. Wood units build creosote that can ignite in the flue. We’ve pulled blazing creosote from Famco flues in Chelmsford homes where the owner “meant to get to it.” The repair cost is always higher than the maintenance would have been. Call (978) 991-9492 for an exact quote - estimates are free.
