Cracked Chimney 

A fireplace adds warmth and charm to any home, but a damaged, cracked chimney poses significant safety risks. 

Many homeowners overlook a common issue—a cracked chimney. Neglecting this problem jeopardizes the stability of your chimney and potentially puts your home in danger. At BQ Basements & Concrete, we recognize the importance of providing the best care. Our expertise lies in offering comprehensive foundation repair for your home, including effectively addressing cracked chimney issues with exclusive foundation repair products and techniques.  

This page explains the causes of chimney cracks and how to rectify the damage to safeguard your home’s stability effectively. 

What Is a Cracked Chimney? 

A cracked chimney indicates visible or concealed breaks in the masonry or stonework of the chimney’s structure. These fractures can appear in various areas, including the flue, chimney crown, and the main body of the chimney. They are particularly noticeable in the mortar joints between the bricks.  

It’s important to note that these cracks go beyond aesthetics; they can lead to severe issues like water leaks, decreased efficiency, and even structural instability. Additionally, you might observe gaps between the bricks in the chimney body, which could result in further damage, potentially causing it to tilt or separate from the rest of the house. 

What Causes Cracked Chimneys? 

Many factors contribute to chimney cracks, with the most common being foundation settlement stemming from unstable soil conditions. 

Clay-based soils with a propensity for expansion are particularly vulnerable to moisture fluctuations. There are several reasons why soil stability may be compromised: 

  • Soil Softening: Intense rainfall, floods, and snowmelt can saturate the soil, making it softer and incapable of supporting the chimney’s weight. 
  • Soil Erosion: Prolonged exposure to excessive moisture and flooding can lead to the gradual erosion of the underlying soil. 
  • Drying and Contracting: During dry spells or droughts, the soil contracts, creating empty spaces where the chimney footing may settle. 
  • Poor Soil Compaction: Proper preparation and compaction of the soil are essential before chimney construction. Skipping or inadequately performing this step can lead to inadequate ground support. 
  • Invasive Tree Roots: Trees near aggressive root systems can disturb and shift the soil as they search for moisture and nutrients. This activity destabilizes the soil, potentially allowing some roots to infiltrate the chimney’s structure. 

Chimneys are typically constructed on a separate foundation from the rest of the house and are particularly vulnerable to these ground-related problems. When the unstable soil cannot provide support it needs, the chimney develops cracks and may even detach from the side of the house. 

Can You Fix Chimney Cracks? 

Yes, repairing cracked chimneys is possible, but taking a comprehensive approach is crucial. 

Simple do-it-yourself repairs like re-pointing bricks, applying sealants, and basic patchwork are temporary solutions. These quick fixes aren’t enough because the chimney will continue shifting on unstable ground, reemerging old cracks or forming new ones.  

A whole-home solution is vital to addressing the issue effectively. Our team at BQ Basements & Concrete identifies the underlying cause of the problem and employs specialized techniques to provide lasting repair. 

We understand that each home structure is unique. That’s why we offer a range of tailored foundation repair solutions to meet your home’s specific needs, including foundation pier systems. 

How to Fix a Cracked Chimney 

The skilled professionals at BQ Basements & Concrete execute the following steps to ensure the permanent stabilization of your foundation, ultimately enhancing the value of your most cherished investment: 

Inspection and Diagnosis 

Our specialists conduct a comprehensive examination of your home, foundation, and chimney. We carefully assess and document the size and position of any cracks and additional damage. 

Install Foundation Piers 

The most effective tools for addressing a damaged chimney are foundation piers, which provide permanent stabilization and have the potential to raise the chimney back to its original position. While this can help in closing cracks and gaps, additional masonry work might be necessary afterward. 

Depending on the soil composition and the chimney’s condition, we install either helical piers or push piers deep into the ground until we reach a stable soil layer. Our SettleStop Helical Pier System is particularly well-suited for lighter loads, such as chimneys. Here’s a breakdown of the process: 

  • Excavate the soil down to the chimney footer. 
  • Utilize hydraulic equipment to advance the piers into the soil. 
  • Monitor the pressure and depth of the installed piers. 
  • Continue advancing the screw-like piers until they reach stable soil or bedrock. 
  • Affix a robust steel bracket to the footing to ensure load transfer. 
  • Install small rivets in the exterior brick as reference points. 
  • Backfill the excavated soil. 

This comprehensive approach ensures a stable and secure foundation for your chimney.  

Annual Maintenance Inspections 

Our diverse service and maintenance programs ensure continued pier reinforcement, supporting the longevity of your chimney. We conduct annual inspections, utilizing a laser level to align with the benchmarks we’ve installed. This guarantees the ongoing security of the system. 

Why Address the Chimney Issues Now 

Postponing repairs for a cracked chimney exacerbate its condition, potentially leading to safety risks and costly future fixes. Here’s why promptly identifying and resolving chimney issues is crucial: 

  • Safety Assurance: Neglecting cracks can result in structural instability and eventual collapse. 
  • Moisture Prevention: Cracks create openings for water infiltration, hastening deterioration and structural problems. 
  • Fire Hazard Avoidance: A compromised chimney poses a risk of tipping over and can become a fire hazard. 
  • Cost-Effectiveness: Early intervention is often more economical than late-stage repairs. 
  • Property Value Enhancement: Maintaining your chimney contributes to an increase in your property’s value.
