Chimney Liner Installation Severn, MD
A chimney sweep in Severn can install a new liner in a flue that is unlined, cracked or the wrong size with a liner sized to the appliance and insulated where the system calls for it. Dial (443) 899-3081 to talk with a local chimney pro about relining.
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. Many older homes, especially those built before the middle of the last century, have no liner at all.
Relining usually comes up for one of a handful of reasons. Damaged clay tiles, missing mortar between tiles or no liner at all are the most common triggers. A new fireplace insert, wood stove or furnace also usually calls for a liner sized to that appliance, since an oversized flue drafts poorly and builds up creosote or condensation.
Before relining, the chimney should get a thorough inspection, usually a Level 2 inspection with a camera run up the flue. The inspection tells you whether relining is truly needed and what kind of liner suits the chimney. You can ask the sweep to walk you through the video.
Chimney Liner Installation is often paired with chimney liner repair and chimney inspection, depending on the cause.

The chimney relining process
Relining a chimney is a careful job that starts well before the liner goes in.
Scan the chimney
The inside of the chimney is checked so the route and condition are known. This confirms what kind of liner the chimney needs.
Match the appliance
Sizing follows the appliance it will serve, since too big or too small both cause problems. The length is measured from the appliance to the top of the chimney.
Clear the path
The flue is swept and any loose tile or obstruction is cleared so the liner can pass. Some chimneys need old tiles broken out to fit an insulated liner.
Install the liner
A flexible liner is fed down the flue, while rigid sections are joined as they go. Many liner systems are tested with insulation for clearance to combustibles.
Connect the appliance
The bottom connects to the stove, insert or appliance, and the top is sealed with a top plate and cap. Every joint is secured so gases stay inside the liner.
Final check
The sweep checks the draft and looks for any leaks. Keep carbon monoxide alarms on every level of the home.
What is included
Chimney liner options
Rigid stainless liners
Straight flues can take rigid stainless pipe which suits wood burning appliances well.
Insulated liners
An insulation wrap or poured insulation surrounds the liner to keep flue gases warm and meet clearance requirements.
Poured liners
Cast in place liners are formed inside the old chimney with a heat resistant mix and can add strength to older masonry.
Flex liners
Flex liners snake through chimneys with bends and offsets and come in grades matched to the fuel.

Stainless Steel Chimney Liner Severn, MD
A stainless steel liner is the standard choice for most homes that need a new flue. Flexible liners make it possible to reline chimneys with offsets, while rigid pipe gives a smooth, heavy wall. The sweep picks a grade of stainless that suits the fuel the appliance burns.
Insulation around the liner helps flue gases rise and keeps the outside of the chimney cooler. A cap and top plate finish the job at the top of the chimney. Homeowners in Severn often choose stainless when adding an insert, stove or new furnace.

Chimney Relining Severn, MD
A chimney is relined when the existing flue cannot safely vent the appliance. It is often recommended after a chimney fire, when clay tiles crack, or when a new appliance needs a different flue size. Relining is usually far less disruptive than rebuilding the chimney.
Have a list of everything that uses the chimney ready when you call (443) 899-3081. If the furnace was upgraded recently, the water heater may now be venting into a flue that is too large. A properly sized liner fixes that.

Chimney Liner Installation Near Me

Chimneys in this climate
Winters here are long and cold, and the heating season usually runs from October well into April. 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. Most homeowners in Severn, MD schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Liner Installation questions
What does a chimney liner do?
The liner is what contains the heat and gases from the fire or appliance. Unlined chimneys or broken liners can let heat or carbon monoxide escape. A camera inspection answers the question for your chimney.
Does a fireplace insert need a liner?
An insert should vent into a properly sized liner, not just into the open smoke chamber. Venting an insert into an oversized clay flue leads to poor draft and heavy creosote. The sweep sizes the liner from the insert specifications.
How long will a new chimney liner hold up?
Stainless liners are built to last many years when they are sized right and swept regularly. Keeping it swept and using dry wood helps it last. Annual inspection helps catch problems early.
What is the difference between a clay liner and a stainless liner?
Clay tiles were the standard in many older chimneys, and they hold up well until they crack. Stainless is the usual replacement because it goes in from the roof without tearing down the chimney. Minor tile damage can sometimes be repaired instead.
What is an orphaned water heater?
When a home switches to a high efficiency furnace that vents out the side of the house, the water heater may be left as the only appliance using the chimney. A big flue with little heat going up it leads to backdrafting and moisture damage. A smaller liner sized for the water heater fixes it, and working CO alarms are essential in the meantime.
