Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Baltimore Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Baltimore, with most jobs running $1,800-$3,400 installed depending on chimney height and diameter. Famco’s 316Ti stainless and aluminized steel liners are built for oil and gas appliances common in Baltimore’s older housing stock, and we carry the full range of diameters from 3″ to 8″ on our trucks. Most Famco liner replacements in Canton, Fed Hill, and the rowhouse corridors near Patterson Park are completed in a single visit.

You’ll usually discover the problem during a routine sweep or when your heating technician flags draft issues. Sometimes it’s creosote penetration through a cracked seam, or corrosion where the liner meets the thimble in Baltimore’s humid summers. Other times the liner has simply reached its service limit after 15-20 years of oil-fired duty.

Which Famco Models This Applies To

Famco produces several liner series, and matching the right replacement matters. The Famco 316Ti Flexible Liner serves wood, pellet, and oil applications with a .006″ wall thickness, while the Aluminized Steel Liner is rated only for gas and oil, not wood. Check the collar label near the top termination, or the stamped band 12-18 inches from the bottom connection. If the label’s worn off, measure the inner diameter with a tape, not a guess, and note whether your appliance is gas, oil, or solid fuel.

We also see a lot of the Famco SmoothWall series in Baltimore’s post-war bungalows, which uses a different coupling system than standard corrugated flex. The SmoothWall’s snap-lock fittings won’t mate with generic corrugated adapters, a compatibility gotcha that costs homeowners a second trip if missed. For OEM-versus-aftermarket, we source direct Famco where the termination and coupling geometry is proprietary. Where the application is standard corrugated flex, we match with equivalent 316Ti from our stocked brands, documented with photos so you see exactly what you’re getting.

Signs Your Famco Flue Liner Replacement Is Failing

• White or orange flaking on the liner walls. This is advanced corrosion from condensing flue gases, common in Baltimore’s shoulder seasons when appliances run below peak temperature. The liner metal is thinning, and pinholes will follow.
• Draft smoke or odor in the basement or utility room. A separated seam or failed bottom connection is leaking combustion gases before they reach the cap. In a Baltimore rowhouse with shared walls, this migrates fast.
• Water staining on the chimney breast or adjacent drywall. The liner’s no longer channeling condensate to the cleanout, it’s saturating the masonry. Baltimore’s freeze-thaw cycle turns small leaks into spalling brick within two winters.
• Your heating tech notes “liner obstruction” or “negative draft.” Often this is collapse or delamination of an aluminized liner that’s reached its 10-15 year gas-service limit, or creosote glazing in a wood application.
• Visible gaps at the thimble or top termination. Famco’s top fittings use a specific clamp-and-band seal. When the band corrodes or the clamp loosens, the liner drops or separates, breaking the draft path.

Replacement Cost & What’s Included

What moves the number: chimney height (a three-story Federal Hill rowhouse versus a single-story ranch), whether we can pull from the top or need scaffold access, and if the existing liner is lodged with creosote cement. We price upfront, in writing, before any work starts. The 90-Day Done Right Promise covers the installation, and the liner itself carries the manufacturer’s warranty, which we register for you.

DIY or Call Us?

There’s a safe middle ground. You can verify your model from the collar label, measure your flue diameter, and check the cleanout for debris or standing water. What you should not do: attempt to pull a lodged liner yourself, or install a replacement without verifying NFPA 211 clearance requirements to combustibles. Baltimore’s balloon-frame construction and lath-and-plaster walls mean hidden voids that a Level-2 camera inspection reveals before we commit to a path.

The real risk is incomplete seating of the bottom connection, or a top termination that looks tight but leaks under draft. We’ve found both in homes where a homeowner’s “simple swap” became a carbon monoxide call six months later. If the flue is right, the fire takes care of itself. Call (410) 849-6273 and we’ll scope it, price it, and get it handled.
