Chimney Liner Installation Shrewsbury, NJ
A sweep in Shrewsbury can reline an unlined or damaged flue so smoke and gases vent safely from a fireplace, stove, insert, furnace or water heater. Call (732) 876-9672 to reach a local chimney sweep.
Inside most chimneys is a liner, the tube that actually carries smoke and flue gases to the top. Without one, heat and acidic condensation attack the masonry, and gaps can let heat or carbon monoxide escape into the home. In older houses, it is common to find an unlined chimney or a clay tile liner that has failed.
Relining usually comes up for one of a handful of reasons. Clay tiles crack after chimney fires, shift as the house settles and lose mortar at the joints, while some chimneys never had tiles to begin with. Installing an insert, stove or high efficiency furnace often means the old flue is the wrong size.
A camera scan of the flue shows the sweep the condition of the old liner and any offsets or obstructions. That reveals whether the existing tiles can be repaired or need to be replaced, and it shows the route a new liner will take. Seeing the inside of the flue makes the decision much easier.
Many chimney liner installation calls in Shrewsbury also turn up a need for chimney liner repair or chimney inspection.

The chimney relining process
Here is how a sweep usually handles a liner installation.
Camera inspection
A camera is run through the flue to check the existing tiles, offsets and obstructions. It decides between repair and relining.
Measure the flue
The liner diameter is matched to the appliance outlet or the fireplace opening, following the manufacturer guidance. The full height of the flue is measured too.
Clean the flue
The flue is swept and any loose tile or obstruction is cleared so the liner can pass. Tight flues sometimes need old tiles removed.
Feed the liner
The stainless liner is lowered from the roof down to the appliance, often wrapped in an insulation blanket. Insulating it helps draft and reduces creosote and condensation.
Make the connections
At the top, a plate and cap close off the flue, and at the bottom the liner connects to the appliance. The connections keep gases from leaking into the old flue.
Test the draft
A draft test confirms the new liner is working. Keep carbon monoxide alarms on every level of the home.
What is included
Chimney liner options
Insulated liners
Liners can be insulated with a blanket or a poured mix where the system or chimney calls for it.
Flexible stainless liners
Flex liners snake through chimneys with bends and offsets and are common for inserts, stoves and gas appliances.
Water heater relining
Smaller liners for gas or oil furnaces and water heaters stop condensation from damaging the chimney.
Rigid stainless liners
Straight flues can take rigid stainless pipe which suits wood burning appliances well.

Stainless Steel Chimney Liner Shrewsbury, NJ
Most relining jobs use stainless steel, which handles high heat and corrosive flue gases well. It comes in flexible coils for chimneys with bends and rigid sections for straight flues. The sweep picks a grade of stainless that suits the fuel the appliance burns.
Stainless liners are often paired with insulation, either a wrap or a poured mix, which keeps flue gases warm and can be required for clearance to combustibles. A cap and top plate finish the job at the top of the chimney. Many Shrewsbury chimneys get a stainless liner when an old fireplace is converted to an insert.

Chimney Relining Shrewsbury, NJ
Chimney relining is the process of lining a flue again when the original liner is cracked, missing or unsuitable. Changing to an insert or stove, finding cracked tiles or recovering from a chimney fire usually leads to relining. In most cases the work is done from the top without tearing into the house.
Before relining, it helps to know which appliances share the chimney. A furnace replaced with a high efficiency model that vents through the wall can leave the water heater alone in an oversized flue, which leads to poor draft and condensation. A smaller liner brings the draft back where it should be.

What the local climate does to a chimney
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, which is how cracks, loose bricks and leaks start. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Shrewsbury is usually booked in the fall, before the first cold night.

Chimney Liner Installation FAQ
Should I replace clay flue tiles with stainless?
Clay tile liners are built into the chimney when it is constructed and last a long time if they stay intact, but they can crack from heat shock, settling or a chimney fire. Stainless steel liners are installed later, from the top, and are used to reline chimneys whose tiles are damaged or missing. Minor tile damage can sometimes be repaired instead.
Why does my water heater flue need relining after a furnace upgrade?
After a furnace upgrade, the water heater may be the only thing left using a flue that was sized for two appliances. That flue is now too big for the water heater, so gases cool, draft weakens and condensation can damage the masonry. Relining with the right size solves the problem, and CO alarms are a must.
What does a chimney liner do?
The liner is what contains the heat and gases from the fire or appliance. Without a sound liner, the chimney is less safe and wears out faster. A camera inspection answers the question for your chimney.
Can an insert vent into an existing chimney without a liner?
Current standards call for a fireplace insert to connect directly to a liner, and most inserts are installed with a full length liner to the top. Venting an insert into an oversized clay flue leads to poor draft and heavy creosote. Check the insert installation instructions for details.
How long does a stainless steel liner last?
A stainless steel liner is a long term fix when it suits the fuel and is kept clean. Chimney fires, heavy creosote and corrosive condensation are what shorten their life. Annual inspection helps catch problems early.
