Relining is the right call when an inspection turns up cracked clay tiles, a flue with no liner at all, gaps between tiles, or a chimney that's simply too large for a new high-efficiency insert. Many of the brick chimneys in the Old Allentown Historic District and around Old Fairgrounds were built for open fireplaces or long-gone coal and oil setups; when a homeowner installs a modern wood stove or gas insert, the original flue is often oversized and needs a properly sized stainless liner to draft correctly. By contrast, if your tiles are intact and the flue is sized right, you likely need only a sweep and inspection rather than a full reline — that honest distinction is what the on-site visit settles.
The trade-off comes down to liner type. A flexible stainless liner bends through the offsets common in older West End and Center City masonry chimneys and is the workhorse for stove and insert connections. A rigid stainless liner suits straight runs and tends to last longer under high heat. Insulation wrap or pour-in insulation is added when the liner sits close to combustibles or when a wood-burning appliance needs to hold flue temperature for a clean draft — important in the wind-exposed taller homes near Cedar Park and the hillier East Side and Rittersville streets. Sizing matters more than brand: an oversized liner cools gases and breeds creosote, while an undersized one starves the appliance.
Every liner job in Allentown starts with measuring the appliance outlet and the flue height, then matching liner diameter to the manufacturer's spec. We finish with a top plate sealed to the crown, a rain cap to keep moisture out of the new liner, and a draft check to confirm the system pulls correctly. For South Allentown, Midway Manor, and Hamilton District homes heating with gas or oil, we also confirm the liner is rated and sized for those flue gases, which are lower-temperature and more corrosive than wood smoke. Conditions like the freeze-thaw cycles common across Lehigh County are hard on unlined or cracked flues, which is why a sound liner protects both the chimney structure and the people inside.
If you're unsure whether you need a reline or just a cleaning, that's exactly what the free on-site visit is for. We'll show you what the camera or inspection finds and lay out your options before any liner is ordered.

Relining Kits & Liner Installation — questions, answered
How do I know if my Allentown chimney needs relining?
You likely need relining in Allentown if an inspection finds cracked or missing flue tiles, no liner at all, or a flue too large for a new insert. A free on-site sizing visit confirms whether you need a reline or just a sweep.
What kind of liner do you install for Old Allentown Historic District homes?
For the older masonry chimneys common in the Old Allentown Historic District, we most often install flexible stainless liners because they bend through offsets in original brick flues. Straight runs may take a rigid stainless liner instead — we size it to your appliance.
How long does liner installation take in Allentown?
Most single-flue stainless liner installs in Allentown are completed in one day once the flue is measured and the liner is on hand. Multi-flue chimneys or jobs needing insulation and extra sealing can take longer.
How much does chimney relining cost in Allentown?
In Allentown, stainless liner installs commonly run roughly $1,800–$4,000 depending on liner type, flue height, and insulation, with a $150 minimum for the sizing visit. These are ballparks — your exact price is confirmed on the free on-site visit.
Can you reline a flue for a gas or oil furnace in Allentown?
Yes. For gas and oil appliances across Allentown neighborhoods like South Allentown and Hamilton District, we install liners rated and sized for those lower-temperature, more corrosive flue gases, then verify the draft before finishing.
