Got chimney problems? We’re here to fix them.
Welcome to The Irish Sweep blog, where we share our chimney maintenance and repair expertise. Chimneys are an essential component of homes with fireplaces or wood-burning stoves, and proper maintenance is critical for their safe and efficient operation. Over time, chimneys can experience a range of issues, including creosote buildup and structural damage. However, there are effective solutions and preventative measures available to address many common chimney problems. In this blog, we will explore the most frequent issues that chimneys encounter and provide guidance on how to resolve them.
Smoking/Performance Issues
One of the most common chimney problems homeowners face is smoking or poor performance. When a chimney is not functioning correctly, it can lead to smoke backing up into the house, causing health problems and damage to the fireplace surround, furniture, walls and even ceilings. Poor performance can also result in low heat output, which can be frustrating for homeowners.
The Solution: There are several solutions to smoking or performance issues, depending on the underlying problem.
- Check for creosote buildup: One common cause of poor performance is a buildup of creosote, a tar-like substance that forms when anything is burned. Creosote can reduce the airflow in the chimney, causing smoke to back up into the house. To address this issue, homeowners should have their chimney professionally cleaned at least once a year.
- Check the damper: Another solution is to check the chimney’s damper, which regulates airflow. If the damper is not functioning correctly, it can lead to poor performance and smoking. If the damper is damaged or needs repair, a professional chimney sweep can provide a solution.
Safety Issues
Chimneys can also present safety hazards, particularly when they are not well-maintained. Safety issues can include fire safety, as well as structural safety issues.
Fire Safety
When creosote buildup or other debris accumulates in a chimney, it can ignite and cause a fire. These fires can quickly spread to the rest of the house, causing significant damage and posing a serious risk to residents.
The Solution: The best way to prevent chimney fires is to have the chimney professionally cleaned and inspected regularly. Homeowners should also avoid burning materials, such as paper, cardboard, and softwood, that can lead to excessive creosote buildup.

Structural Safety
Chimneys can also present structural safety hazards, particularly if they are not well-maintained. Over time, chimneys can deteriorate, leading to cracking, shifting, or collapse. These issues compromise the safety of the chimney and the rest of the house.
The Solution: To address structural safety hazards, homeowners should have their chimney inspected by a professional chimney sweep. A chimney inspection can identify any structural issues that need to be addressed, such as cracks, shifting, or other signs of deterioration. Trust us – you don’t want to risk the consequences of neglecting a structural problem.
Seismic Safety
In areas prone to earthquakes (hello, Bay Area!), chimneys can pose a significant safety risk if they are not adequately secured. During an earthquake, a poorly secured chimney can collapse, causing considerable damage and endangering residents. This is a major chimney problem that can cause serious harm if not addressed.
The Solution: To address seismic safety hazards, homeowners should have their chimney inspected by a professional chimney sweep. A professional can assess the chimney’s seismic safety and recommend any necessary repairs or upgrades.
Height Reduction
In general, a taller chimney without proper reinforcement poses a potential risk of collapse, especially in high-wind areas or earthquake-prone regions. This can raise concerns regarding seismic liability, efficiency, and fire safety.
The Solution: A professional chimney sweep can assess the chimney’s height and recommend any necessary height reduction measures, such as capping or shortening the chimney.
Mortar Issues
Another common chimney problem is deteriorating mortar, which can lead to gaps between the bricks or stones in the chimney. These gaps can allow water to penetrate the chimney, leading to further deterioration and damage.
The Solution:
Mortar issues are a common chimney problem, and they can lead to a variety of other issues such as smoking, safety hazards, and structural damage. Mortar is the material that holds the bricks or stones of a chimney together and it is water soluble. Over time, it can become cracked, loose, or deteriorated, which can cause problems with the chimney’s integrity. Here are some solutions to address mortar issues:
Repointing
Repointing is the process of removing old, damaged mortar and replacing it with new, fresh mortar. This is typically the go-to solution for mortar issues. A skilled chimney sweep can assess the extent of the damage and determine if repointing is necessary. If so, they will carefully remove the old mortar and replace it with new, high-quality mortar that matches the existing mortar in color and texture.
Tuckpointing
Tuckpointing is a more specialized form of repointing that involves adding a second layer of mortar to the joints to give the appearance of a very thin, well-defined joint line. Tuckpointing is often used for chimneys with intricate brick patterns, as it can enhance their appearance and improve the overall look of the chimney.
Waterproofing
Waterproofing is another option to address mortar issues. Waterproofing involves applying a product with a 10-year guarantee to the surface of bricks or stones to prevent moisture from penetrating the masonry and the mortar. This can help prevent further damage and extend the lifespan of the chimney. However, waterproofing is not a long-term solution for severe mortar deterioration, and it is essential to have the chimney inspected regularly to ensure the sealing product is still working effectively.
Rebuilding
If the mortar damage is extensive and severe, rebuilding the chimney may be the only solution. This involves completely removing the existing chimney and building a new one from scratch. While this is a more expensive and time-consuming option, it may be necessary to ensure the safety and structural integrity of the chimney. Please note, this may not be an option in your area as many cities will not issue a permit to construct a new chimney.
Cosmetic Issues
While cosmetic issues with chimneys are generally not safety concerns, they can detract from the home’s appearance and reduce its value.
The Solution: If cosmetic issues are a concern, homeowners may want to consider cosmetic repairs, such as painting or resurfacing the chimney. A professional chimney sweep can assess the extent of the damage and recommend the best course of action.
Whether the issue is smoking or performance problems, safety hazards, mortar deterioration, or cosmetic issues, there are effective solutions available to address these problems and keep chimneys in good working order.
