The Dangers of a Chimney Leak

The Dangers Of A Chimney Leak

Did you know a chimney leak can cause serious problems for homeowners? As with all leaking water, the moisture caused by a chimney leak will cause mold, which can cause an array of different health hazards to you and your family. If left untreated the cost of mold removal can get pricey with repairs costing upwards of $6,000 in some cases. 

Not only can a leaking chimney cause black mold, water leaks can also cause physical damage ranging from cosmetic to extensive deterioration to the structure of your home. Water damage can ruin your home faster than some may think. Did you know within 24 hours water exposure to your roof, ceiling and walls can cause irreversible damage to the structural integrity of your home. Getting leaks repaired quickly is the only way to prevent your leaky chimney from damaging your home.



Black Mold

The Environmental Protection Agency warns that Black Mold can be harmful to your health. If a leak in your Chimney allows moisture to enter your home, and if that moisture encounters porous surfaces, especially wood, it can trigger the growth of mold. Though some mold is more unsightly than dangerous, black mold can be a real problem to the health of you and your loved ones.

• Asthma

• Headaches

• Irritated Sinuses

• Chronic Fatigue

• Depression

Dangers Of Black Mold


If you have a mold allergy and asthma, your asthma symptoms can be triggered by exposure to mold spores. In some people, exposure to certain molds can cause a severe asthma attack. Signs and symptoms of asthma include:

  • Coughing
  • Wheezing
  • Shortness of breath
  • Chest tightness


Black mold exposure can cause headaches if you are allergic to mold, and that results in sinus inflammation or nasal allergies. Chronic congestion of the sinuses and nasal allergies can cause headaches very easily.

Irritated Sinuses:

In the event mold fungus finds its way into the sinus cavity, the immunity in the body reacts by releasing a chemical known as eosinophils to fight the fungi. This substance is what causes fungal sinusitis and will cause irritation for as long as the fungi are within the sinus.

Chronic Fatigue:

The most common symptom of toxic mold is fatigue. Chronic fatigue is something many people complain about when they’ve been exposed to household mold for a long period of time. While respiratory symptoms are often rapidly attributed to mold, people are not so quick to attribute fatigue to the presence of mold in the home. They may not realize that exposure to mold can cause fatigue or they may simply assume the fatigue is due to something like, like a busy schedule or just not getting enough sleep.


A groundbreaking public health study has found a connection between damp, moldy homes and depression. Residents who live in visibly damp, moldy households risk for depression averaged 34–44% higher than that for residents of mold-free dwellings.

Rotting Wood

As excessive moisture builds up in wood it can begin to rot. When an entire wall, roof or ceiling has been affected, the repairs can be extensive and expensive.

Roof Damage:

Water seeps in between the metal flashing that the chimney and travels to the wood roof decking.  Water damages the roof decking and can lead to needing to replace your roof.  Getting leaks repaired quickly is the only way to prevent your leaky chimney from damaging your roof damage. Check out our roof leak resolutions


Ceiling And Wall Damage:

When water enters the home from a chimney leak It may run down a rafter to puddle above the ceiling. When water puddles above your ceiling it can cause wood and plaster to lose their structure and sag as well as wall paper and paint to come off walls leading to extensive damage and repairs.  schedule an appointment for a free estimate


Causes of a Chimney Leak

Damaged or Missing Chimney Cap:

A damaged or missing chimney cap can’t keep out the elements caused by bad weather such as rain, snow and even moist debris from entering your chimney. Chimney caps are used to prevent rain and snow from deteriorating the inside of your chimney. Stainless steel mesh within the cap helps as a spark arrestor, and minimizes burning debris from rising out of the chimney. Chimney caps can be stainless steel, copper, Kydex colored steel and more. Ageless Chimney stocks all traditional caps on our trucks, and can also provide custom caps in any shape and size. read more About Chimney Caps Chase Covers

Cracked Cement Crown:

Cracks in the chimney crown allow water to leak into the flue lining causing damage to your liner. 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 is a stainless steel tube used to bypass traditional masonry chimneys that may be old, damaged or need to be brought up to code. Chimney liners are recommended for all unlined masonry chimneys, and chimneys with any cracked or damaged terracotta clay flues. Ageless Chimney liners are stainless steel, crush proof, and come with a lifetime warranty.

Degraded Chimney Bricks:

Seasonal freezes and thaws eventually degrade porous bricks and result in slow seepage. The frozen water inside the brick expands slightly and the brick begins to crack. The bricks freeze and thaw repeatedly, continuing the process until the front of the brick begins to flake off resulting in a leaking chimney. A damp chimney will stain the ceiling and the chimney opening, as well as walls around the fireplace. This is caused due to a number of factors that trap moisture, mainly, porous clay bricks, unvented flue and rainwater

Deteriorated Chimney Mortar Joints:

Older mortar joints deteriorate and allow moisture to leak into the structure. A common repair for deteriorated mortar joints is called repointing. In this process, the existing mortar joint is cut to an appropriate depth and the joint is repacked with new mortar. The joint is then cut to form a concave surface that will direct water out of the joint. We repair all types of masonry related chimney problems, and are highly specialized in loose bricks, mortar repair, leaky chimneys, rebuilds, repointing and matching new brick to old. read more About Masonry Brick

Damaged Metal Flashing:

Damaged chimney flashing can’t hold a waterproof seal between the chimney and roof. If your flashing is warped or flared, it may be damaged or worn out beyond repair. Without flashing, or when flashing is damaged or deteriorating, the risk of leaks increases greatly. Leaks can have a cascading effect on homes, causing large amounts of damage well beyond the roof. If a leak is not noticed and fixed immediately, a home can experience water damage leading to expensive and extensive repairs.

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.

FAQ About Chimney Liners

What is NFPA?

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


How can I tell if I need a new chimney liner?

It is time for a new chimney liner once the current liner is broken, has cracks, or is unsafe. If your chimney does not have a chimney liner, Ageless Chimney highly recommends installing one. 


How long do chimney liners last?

The lifespan of a chimney liner depends on its type and quality of the chimney liner. Clay flue chimneys last around 50 years. Whereas metal chimney liners last 15 to 20 years. Thus, Ageless Chimney’s choice, Lifetime Chimney, offers a lifetime guarantee on their chimney liner products. 


How can I prevent a chimney fire?

Having your chimney swept and inspected once a year can prevent chimney fires. Ageless Chimney technicians perform chimney inspections that check for any problems or damage to your chimney. 


Why do I need to insulate my chimney?

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
