What Is a Cracked Chimney?

A cracked chimney refers to visible or hidden fractures in the masonry or stonework of the chimney structure.

Cracks manifest in various areas, such as the flue, chimney crown, and the body of the chimney. As seen here, they are most prominent in the mortar joints between the bricks. These fractures are more than a cosmetic issue; they can lead to severe problems, including water leaks, reduced efficiency, and structural instability.

You may also notice gaps between the bricks in the chimney body, which can result in additional damage, causing it to lean or pull away from the rest of the house.

What Causes Cracked Chimneys?

Several factors lead to cracked chimneys, the most prevalent being foundation settlement rooted in soil instability.

Ohio and Northern Kentucky are rich in expansive clay-based soils susceptible to moisture fluctuation.

Soil can become unstable due to a variety of reasons, including:

Wetting and Softening: Heavy rains, flooding, and snowmelt saturate the soil, making it softer and unable to bear the weight of the chimney.
Erosion: Excessive moisture and flooding can cause the underlying soil to erode over time.
Drying Out and Contracting: The soil contracts during dry periods or drought, creating voids into which the chimney footing can settle.
Poor Compaction During Construction: The soil must be properly prepared and compacted before building the chimney. If this step is missed or not completed thoroughly, the ground may not be able to support the structure.
Invasive Tree Roots: Nearby trees with invasive root systems can dislodge and shift the soil as they seek moisture and nutrients. This activity destabilizes the soil, allowing some roots to penetrate the chimney’s structure.

Since chimneys are often not built on the same foundation as the rest of the house, they are especially susceptible to these soil-related issues. When the unstable soil fails to support the chimney adequately, it begins to crack and may separate from the side of the home.

Can You Fix Chimney Cracks?

Yes, cracked chimneys can be effectively repaired, but it’s essential to approach the problem holistically.

DIY repairs such as repointing bricks, applying sealants, and simple patchwork are temporary fixes that won’t suffice. The chimney will continue shifting on the unsteady ground, reopening old cracks or creating new ones.

A whole-home solution is necessary to resolve the issue. Our team at Ohio Basement Authority identifies the underlying cause of the issue and employs specialized techniques to deliver a permanent solution.

As homeowners ourselves, we understand that each house is unique in its own way. We offer various foundation repair solutions customized to your home’s needs. These include foundation pier systems.

How to Fix a Cracked Chimney

Inspection and Diagnosis

Our experts thoroughly inspect your home, foundation, and chimney. We evaluate and note the extent and location of the cracks and other damage.

Install Foundation Piers

The best tools to address a damaged chimney are foundation piers that permanently stabilize the chimney and can help lift it back to its original position. This may help close cracks and gaps, but further masonry may be needed afterward.

Depending on the soil and condition of the chimney, 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 ideal for lighter loads, including chimneys. Here’s what the process entails:

Excavate the soil down to the chimney footer
Use hydraulic equipment to advance the piers into the soil
Monitor the pressure and depth of installed piers
Advance the screw-like piers until they reach stable soil or bedrock
Attach a durable steel bracket to the footing, ensuring load transfer
Install small rivets in the exterior brick as benchmarks
Backfill excavated soil

Annual Maintenance Inspections

You can use our various service and maintenance programs to guarantee the piers continue reinforcing the chimney. We return for annual inspections, aligning a laser level with the benchmarks we installed. This confirms the continued security of the system.

Why Address the Chimney Issues Now

Delaying cracked chimney repairs worsens the chimney’s condition and leads to safety hazards and costly future repairs. Here’s how you’ll benefit from quickly identifying and resolving these issues:

Avoid Safety Concerns: Ignoring cracks can lead to structural instability and eventual collapse.
Prevent Moisture Intrusion: Cracks allow water infiltration, which accelerates deterioration and structural issues.
Evade Fire Hazards: A compromised chimney is in danger of tipping over, as well as a fire hazard.
Cost-Efficiency: Early intervention is often less expensive than late-stage repairs.
Boost Home Value: Maintaining your chimney enhances your property value.
