All About Chimney Liner Installation

Chimney liner installation is a common service that is a great way to increase the safety of your home. This is one of the many services provided by Ageless Chimney. Chimney liners can further assist in the function of other appliances in your home. It is very important to have a liner to prevent moisture and combustible products from seeping into the masonry of the chimney. 


A chimney lining system is intended for use with all traditional home heating appliances that use oil, gas, or wood, and vent through a masonry chimney. A chimney liner installation is recommended for all unlined masonry chimneys and chimneys with any cracked or damaged terracotta clay flues. Ageless Chimney chooses liners that are stainless steel, crush-proof, and come with a lifetime warranty.


Chimney Anatomy

Below are diagrams of the anatomy of the chimney. 

Fireplace Insert diagram in long island ageless chimneyboiler chimney ageless chimney in long island ageless chimneyfireplace diagram ageless chimney in long island


Boiler Chimney

Carbon monoxide and water vapor from the boiler releases from the home using the boiler flue/chimney.  


Boiler/Water Appliances 

These appliances connect to the chimney flue to vent properly from the house. The appliances chosen in the home perform better when properly attached to the chimney liner.


Bottom Plate 

The component is used to seal the fireplace and chimney liner.


Chimney Cap

This piece covers the top plate. The chimney cap prevents weather and other elements from harming the chimney flue. In addition, the function of the chimney cap includes allowing chimney gases to vent out from the top. 


Chimney Liner

A stainless steel round or oval pipe is installed in the chimney flue, venting harmful gasses and water vapor to exhaust from the top of the chimney.


Chimney Flue

A clay, ceramic, or metal passageway is installed inside of a chimney. The chimney flue contains the combustible exhaust, directing it to the outside atmosphere. Most importantly it protects the chimney walls from heat and corrosion.


Chimney Parge

The bonding agent of mortar concrete is applied to the inclined walls of the smoke chamber. This gives it a smooth surface and allows the fireplace smoke to enter the chimney flue. In addition, parging the chimney protects the walls from the high temperature of the fire. 


Fire Box

The location where the fire burns. There are masonry and metal fireboxes. This depends on the type of fireplace. 



A structure connected to the chimney, is made of brick, stone, or metal that can contain a fire. 


Fireplace Insert 

Stone, wood, or gas appliances that are already inside of a fireplace. The function is to increase the heat generated.



Installed in between the chimney masonry and liner, the insulation helps prevent creosote buildup. Two types of chimney insulations include TherMix and insulation blankets. The choice of insulation depends on the amount of space in this area. 



The connector between the chimney liner and appliance. 


Smoke Chamber

With the help of the slanted walls, the smoke chamber compresses the exhaust gases into the chimney flue. This area of the chimney also refers to the draft created in this space. When built properly, the smoke chamber will have a good draft.  


Smoke Pipe 

Used as a ventilation system for attached appliances.


Stainless Steel Chimney Liner

This liner is more beneficial to wood-burning stoves and fireplaces. Stainless steel chimney liners keep the chimney walls protected for many years. 


Stainless Steel Tee

The tee attaches the chimney liner and smoke pipe for other appliances. 


Tee Cap/Clean Out

Chimney ashes are collected at the clean-out door. It should also seal properly to prevent drafts. 


Top Plate

Placed at the top of the chimney liner, the top plate prevents water and other weather elements from entering the chimney flue. 


Wood Stove Adapter

The point where the stovepipe and chimney liner connect for stove appliances.



Reasons to Install a Chimney Liner

  •  Fire Safety
    • An essential layer of fire protection between heat and combustible framing around the chimney.
  • Improved Performance
    • Improves draft and operation of appliances.
  • Easy and Effective Cleaning
    • Minimized soot and creosote build-up, little cleaning.
  • Long-term Preservation
    • The liner acts as a barrier against water damage.
  • Reduces Creosote Buildup
    • Extreme buildup of creosote is a major cause of chimney fires. The expansion and contraction of the chimney liner allow the creosote to break off.



Types of Chimney Liners

The experts at Ageless Chimney have years of installing chimney liners. Our team has been helping homes every day stay protected with chimney liners. Chimney liners allow the smoke to have an exit point, preventing combustible products from staying trapped. Check out our team installing a liner by watching this youtube video on Long Island. 


Clay Tiles

A traditional type of liner that can last for many years. Older homes have clay tiles installed. To update the chimneys, many replace them with a stainless steel liner. A drawback with clay tiles is that when fires occur, it is more likely for masonry to break and allow the fire to spread quickly. It is also very challenging to repair clay tiles, often the reason for the transition to a metal liner. 


Cast in Place Chimney Liners

To form a new flue, chimney experts pour concrete mortar into the chimney. This improves the chimney structure. This liner is also very challenging due to the installation process. 


Metal Chimney Liners

There are two types of common metal chimney liners. The first type of liner is the stainless steel chimney liner. This is a very popular choice on Long Island due to the many benefits.  Wood-burning stoves and fireplaces use stainless steel liners. The benefits include resistance to corrosion, higher temperature regulation, and a long lifespan. Whereas gas appliances use aluminum chimney liners.

What is NFPA?

NFPA is the National Fire Protection Association that provides guidelines for fire safety.

Chimney insulation helps the temperature stay regulated. Then makes the flue gases warmer and increases the speed of ventilation upward, preventing condensation build-up. 



What Our Clients Say

Below are testimonies from our great clients regarding our chimney liner installation services. 


“I found this company through online reviews and was very pleased with the work they performed! I had part of the chimney rebuilt, an inner steel liner installed, and point entire chimney. They were prompt, professional, and excellent work! They cleaned up afterward where you would never know there was any construction work done prior! Nick was great, he remembered all tasks we discussed during our consultations and completed them all. Highly recommend them.” – KC from Massapequa, NY


“Our oil company came to do the annual boiler cleaning and said there was a nest in the chimney. I had their recommended chimney company come for an estimate and they said we needed a new liner and brickwork (we have a very old house so I wasn’t surprised), but their price seemed high. I’m usually wary about calling a company without a personal recommendation, but I called Ageless based on their online reviews and couldn’t be happier. Their price was considerably less than we were quoted by the first company. They arrived on time, we were able to do the work the same day and were done in about an hour. The guys were very professional and everything was clean when they left. Don’t be surprised if you see this same review on other websites – I’m very happy to recommend this company!” – Isabel F. from Merrick, NY


Just had Ageless (Nick and Brian) come and install a new chimney liner and chimney cap, and rebuild flashing. Super personable, friendly, and very helpful in explaining the process and giving suggestions for the future, as well as being kind and patient with the 200 questions we posed. They were professional and respectful of my home and cleaned up meticulously. I was beyond impressed with their work, and would highly recommend them for any of your chimney needs.” – Melissa C. from Lindenhurst, NY

Benefits of Waterproofing a Chimney

Waterproofing a chimney is the best way to resolve a leaky chimney. Would you leave your windows open if it was raining outside? What if it was pouring? Or even snowing? Well, you are doing all that and more if you have a chimney that is cracked. And the scary part is you may not even know it. Even tiny cracks can expose your chimney to moisture, freezing, cracking, and deterioration. The porous masonry absorbs water and can result in these damages. The more water absorbed, the more dangerous it can be for the chimney system. Below lists the reasons a chimney can be leaking, regardless of the season. Our Ageless Chimney team is a professionally fully insured company dedicated to all aspects of the chimney including repairing chimney leaks and waterproofing


Causes of Chimney Leakage

There are some visible signs of water damage on chimneys. Some include discoloration, cracking, spalling, or gapping of the masonry. If you have seen any of these signs form or begin in your chimney, it is time to call the professionals at Ageless Chimney. Other causes of chimney leakage include:

Damaged Flashing: Chimney flashing is the sheet of metal installed around the area where the chimney meets the roof. The flashing ensures that the connection between the chimney and roof is watertight. Chimney flashings have to be replaced after extreme wear and tear, which happens over some time. 

Damaged Chimney Cap: Chimney caps are a very important part of the chimney to prevent rain and snow from deteriorating the inside of your chimney. Popular chimney caps include stainless steel, copper, and Kydex colored steel. Some include a stainless steel mesh that helps as a spark arrestor to minimize burning debris from rising out of the chimney. In addition, the cap also provides a barrier to present animals and debris falling into your home. If the chimney cap is damaged, it is very possible that it is the reason for the chimney leaking.

Missing Mortar: If water is absorbed by the masonry, it can be very easy for damage to occur. Gaps and missing mortar will allow water to easily access the structure of the chimney which can result in even more damage. 


Reasons to Waterproof your Chimney

Hiring a professional, like Ageless Chimney, for a waterproofing service has many benefits. Regardless of the homeowner uses the chimney, waterproofing is recommended to maintain the structure. Sealing the masonry, even before cracks begin to form, prevents water damage, making the chimney structure last longer. In addition, replacing a chimney crown or other elements of the chimney can be costly. In addition to masonry repair, an important element of the chimney is chimney crowns. Other benefits to waterproofing a chimney include:

1. Block water absorption from mold and vegetation growth in and on your masonry.

2. Keep your brick and mortar from cracking, spalling, or gapping.

3. Protect your masonry from black and white discoloration.

4. Allow your brick and mortar to “breathe” and release water vapors.
