Famco Flue Liner Replacement in Orlando, FL

Famco Flue Liner Replacement: The Orlando Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Orlando, with most jobs running $1,800 to $3,400 installed depending on height, diameter, and access. Same-day service is available when you call before noon, and we carry the common Famco diameters on every truck. Most Orlando homeowners discover the problem during a routine sweep or when they notice white efflorescence staining the exterior brick, a telltale sign that exhaust gases are leaking through a compromised liner rather than venting properly.

Which Famco Models This Applies To

Famco built flue liners in several series over the decades, and identifying the right replacement starts with the collar stamp or the data plate on the chimney cap assembly. The 316Ti stainless series, common in Orlando homes built between 1985 and 2005, carries a part number prefix of FL-316 followed by the diameter in inches. The earlier 304-grade series, often found in College Park and Winter Park bungalows from the 1970s, used a simpler numeric stamp that can corrode to near-illegibility.

We match OEM Famco spec where the original part number is readable. When it is not, we measure the inner diameter at the thimble, check the total linear feet from appliance collar to cap, and note whether the original was rigid or flexible. Our trucks carry both: rigid 316Ti for straight flues in newer Orlando construction, and DuraFlex and Gelco flexible liner for the offset flues common in Maitland and Altamonte Springs homes where the fireplace does not align vertically with the chimney crown. Hearthstone Chimney Co. of Orlando is an independent service provider, not affiliated with Famco.

The aftermarket decision for Famco specifically comes down to alloy grade. Some budget liners sold as “compatible” use 304 stainless at 0.006 inch wall thickness, which in Orlando’s salt-air climate and frequent summer rain cycles can fail in under eight years. We use 0.010 inch 316Ti or AL29-4C for oil and gas condensing applications, the same specification Famco originally specified for this climate zone.

Signs Your Famco Flue Liner Replacement Is Failing

• White powder or crystalline deposits on exterior brick. This is efflorescence, and it means moisture combined with flue gases is migrating through cracks in the liner and condensing in the masonry. In Orlando’s humidity, this accelerates once it starts, and the underlying liner damage is usually worse than surface staining suggests.
• Strong smoke odor when the fireplace is not in use. A intact liner maintains negative pressure that draws air upward. When the liner is perforated or separated at a joint, reverse airflow on still, humid days pushes chimney odors into the living space. We see this most often in one-story ranch homes near Lake Apopka where wind patterns create downdraft conditions.
• Visible gaps or rust streaks at the thimble or cleanout door. The thimble connection is where Famco liners most commonly fail first, especially if the original installation used a single-wall adapter rather than the insulated transition. Rust streaks mean the liner wall has breached and moisture is reaching the outer jacket.
• Flaking or spalling tile in the firebox. When exhaust cools too quickly due to liner damage, condensation runs back down and saturates the firebox refractory. The freeze-thaw cycle is minimal in Orlando, but the thermal shock from rapid heating of waterlogged tile causes the same spalling.
• Carbon monoxide detector alerts near the hearth. This is the symptom that cannot wait. A compromised liner allows combustion byproducts to leak into wall cavities or the living space before diluting in outdoor air. If your detector sounds, evacuate and call us from outside.

Replacement Cost & What’s Included

For Orlando homes, Famco flue liner replacement typically falls between $1,800 and $3,400 installed. The lower end covers a straight 25-foot run of 6-inch flexible 316Ti in a single-story home with good roof access. The upper end applies to two-story homes in neighborhoods like Baldwin Park or Thornton Park where we must work around mature oak canopy, use rigid liner with multiple offsets, or upgrade to AL29-4C alloy for high-efficiency gas inserts.

Every quote includes the liner material, insulation wrap where required by Orlando building code for zero-clearance fireplaces, a new top plate and rain cap, and connection to your appliance. Our Level-2 camera inspection, photos you can see, and the plain-English verdict are included. The 90-Day Done Right Promise covers the installation in writing, no arguing. A square deal: no surprises on the bill.

DIY or Call Us?

An owner can safely check the collar stamp, measure approximate flue diameter with a tape measure, and photograph any exterior staining for our reference. What you cannot safely do is descend the flue, work on a steep roof, or handle the liner itself. The old liner must be extracted, often in sections, without damaging the clay tile surround or the chimney crown. The new liner must be sized precisely; an undersized liner creates draft problems and creosote buildup, while an oversized liner cools too quickly and condenses acidic moisture that destroys the liner from the inside.

More critically, Orlando requires a permit for liner replacement and a post-installation inspection for most fuel types. We pull the permit, coordinate the inspection, and warranty the work. A clean chimney is not a luxury - it is just the job done right. Call (877) 565-7563 and a live person will answer, any hour, any day.
