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 Owings Mills: What to Know First
As an independent Famco service provider, Hearthstone Chimney Co. repairs and replaces Famco chimney liners and rebuilds Famco-equipped flues throughout Owings Mills, typically completing liner jobs in one visit and most rebuilds within two days. We use professional-grade Famco-compatible materials from our trusted supplier network, and we never recommend work you can’t see for yourself on camera. Most Famco liner replacements in Owings Mills run between $2,800 and $4,500 depending on flue height and diameter, with a written estimate agreed before we start. This page is for homeowners who know they’ve got Famco components in their chimney and want straight answers about whether to repair, replace, or rebuild. Call (443) 998-2617 and a live person will pick up, any hour.
How Famco Products Fail - and How We Fix Them
- Famco SL-Series flexible liners develop pinpoint corrosion at the flex points after 12-18 years in Owings Mills, where freeze-thaw cycles accelerate moisture intrusion through the crown. The SL-600 and SL-800 are particularly prone to this where they bend above the smoke chamber. We cut back to sound metal and splice in matching-gauge Famco-compatible flex, or switch to a rigid DuraFlex equivalent if the run allows.
- Famco rigid 304 stainless liners warp at the thimble connection in homes near the reservoir zone with heavier condensation loads. The rigid line’s seam weld holds, but the metal fatigues right at the appliance adapter. We replace with a heavier 316Ti alloy section or full liner when the damage extends past the first flue tile.
- Famco top-sealing dampers seize in the open position on chimneys we rebuild, especially the TD- series installed in 1990s colonials off McDonogh Road. The cast-aluminum frame cracks from thermal cycling, and the cable housing fills with creosote sludge. We remove the damper during rebuild, inspect the flue for collateral damage, and install a new Gelco or Famco-compatible damper with a stainless cable run.
- Famco galvanized chase covers rot through at the drip edge in 10-14 years, faster than the stainless models. Water runs down the flue and destroys the liner from the outside in. We fabricate a replacement from heavier-gauge copper or stainless, slope it properly for Owings Mills snow loads, and verify liner integrity before we close it up.
- Famco smoke chamber parging delaminates in older Owings Mills homes where original construction used inferior mortar. The Famco liner then loses lateral support and shifts, stressing connections. We parge with HeatShield Cerfractory Foam or remove and rebuild the chamber in firebrick, depending on access and budget.
Our Famco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers (443) 998-2617 any time. We book a Level-2 camera inspection, not a sales visit.
- 2
Inspect and document. Our tech runs a camera the full flue length, photographs every defect, and gives you a plain-English verdict. You’ll see what we see. No surprises.
- 3
Diagnose and specify parts. We determine whether your Famco component can be repaired with OEM parts, needs a quality aftermarket equivalent from our DuraFlex, HeatShield, or Gelco inventory, or requires full replacement. We explain the trade-offs and warranty implications.
- 4
Price and approve. You get one written estimate. The number on it is the number on the invoice. We apply any standing discount you’re entitled to - senior, veteran, or seasonal - before you sign.
- 5
Execute and test. Background-checked, uniformed technicians complete most Famco liner and rebuild jobs in a single visit. We pressure-test or smoke-test every liner before we leave.
- 6
Guarantee and follow up. The 90-Day Done Right Promise covers everything in writing. If it’s not right, we come back. No paperwork, no arguing.

Why Owings Mills Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve been answering the phone with a live person for over 42 years, and we’ve learned that Famco owners in Owings Mills want two things: someone who knows the difference between an SL-600 and a rigid 304, and someone who won’t invent problems to sell a bigger job. Our Level-2 camera inspections end with photos you can see and a plain-English verdict. If your Famco liner has five years left, we’ll say so. If it’s failed and taking the masonry with it, we’ll show you exactly where and why.
The 90-Day Done Right Promise means in writing, no arguing - if it’s not right, we make it right. Our technicians are background-checked, uniformed, and carry Famco-compatible parts plus backup inventory from DuraFlex, HeatShield, and Gelco so most jobs finish in one visit. We’re not the cheapest outfit in town. We’re the one that plans to be here when you need us again.
FAQs
The original Famco warranty on most residential liners expired years ago based on install date, not ownership transfer. As an independent Famco service provider, our repairs carry their own workmanship guarantee under the 90-Day Done Right Promise, but we cannot extend or honor manufacturer warranties that have lapsed. We document every part source so you know exactly what you’re getting. Call (443) 998-2617 if you want us to verify your install date and warranty status.
Yes, for most Famco series installed in Owings Mills from the 1990s forward. We stock common diameters and adapter sizes, and our supplier network covers the full Famco catalog plus quality aftermarket equivalents from DuraFlex and Gelco when OEM lead times stretch. For discontinued lines, we fabricate transitions in-shop or specify a compatible replacement liner system. We’ll tell you before we start if your part is back-ordered.
A Level-2 camera inspection tells the story. Localized corrosion or a single failed joint often repairs cleanly. If we find generalized thinning, multiple breaches, or corrosion where the liner passes through a deteriorating smoke chamber, replacement is the sound call. We show you the footage and explain which category you’re in. No camera evidence, no recommendation. Call (443) 998-2617 to schedule.
Most partial rebuilds with liner replacement finish in two days. Full exterior stack rebuilds run three to five days depending on height, weather, and whether we’re matching existing brick. We don’t rush masonry - it cures on its own schedule. We’ll give you a firm timeline in your written estimate.
A breached liner lets combustion gases, including carbon monoxide, leak into wall cavities and living spaces. In Owings Mills, where many homes have tightly constructed upper floors, that risk is real. Creosote can also reach combustible framing if the liner is perforated. We don’t scare-sell, but we don’t soft-pedal it either: a failed liner is a safety issue that deserves a straight answer and a timely fix. Call (443) 998-2617 for a free inspection.
