Understanding Brick Mortar Rattling in Lombard Homes

Homeowners in Lombard, IL, and surrounding suburbs like Wheaton, Glen Ellyn, and Addison often notice strange noises coming from their exterior walls during the windy months. A distinct rattling, clicking, or clinking sound from a specific spot in the brickwork is rarely just “settling.” In the Midwest, where temperatures fluctuate significantly between day and night, and where winter brings repeated freezing and thawing, brick mortar is under constant stress. When a spot in the mortar fails, it can create a small void behind the brick. As wind hits the house, the pressure changes can cause the loose brick or detached mortar fragment to vibrate or shift slightly within that void, producing the audible rattle.

This issue is particularly prevalent in older homes built before modern mortar mix standards were widely adopted. Many Lombard homes feature soft, lime-based mortars that are more porous and susceptible to water absorption. When water enters these pores and freezes, it expands, pushing the mortar away from the brick face. Over time, this process, known as spalling or delamination, can leave a brick partially detached. While the wall may still look intact from a distance, the compromised bond creates the conditions for rattling. Addressing this early is crucial for maintaining the curb appeal and structural integrity of your home, whether it is a single-family residence, a townhome, or a multi-unit apartment building.

Common Causes of Rattling Brick Mortar

Identifying the root cause of the rattling is essential for determining the correct repair method. In Lombard’s climate, several factors contribute to this specific problem:

Freeze-Thaw Damage: This is the primary culprit in Illinois. Water seeps into tiny cracks in the mortar. When temperatures drop below freezing, the water expands by approximately 9%, exerting pressure on the surrounding brick and mortar. Repeated cycles weaken the bond until a piece of mortar breaks loose or a brick shifts. The resulting gap allows the brick to move slightly in the wind.

Improper Previous Repointing: If the mortar was previously repaired with a modern, hard Portland cement mix on an older, softer brick wall, the new mortar may not flex with the building’s natural movement. This rigidity can cause the new mortar to crack and detach, or it can cause the softer brick itself to crumble, leading to loose sections that rattle.

Pest Intrusion: Small gaps created by deteriorating mortar can become entry points for pests such as mice, squirrels, or even insects. These animals may nest in the void behind the brick, and their movement can dislodge mortar fragments, creating a rattling sound. Additionally, the pests themselves may be heard moving within the wall cavity.

Settling and Structural Movement: While less common for isolated spots, general settling of the home’s foundation can cause stress points in the masonry. If a section of the wall has shifted slightly, the mortar joints may have cracked, allowing individual bricks to become loose. This is more likely in older homes or those built on expansive clay soils common in the Chicago area.

What to Look For: Diagnostic Signs

Before contacting a handyman, you can perform a safe visual inspection to gather information that will help in the assessment. Look for the following signs around the rattling spot:

Visible Cracks: Examine the mortar joints surrounding the rattling brick. Are there horizontal, vertical, or stair-step cracks? Cracks that are wider than 1/8 inch may indicate significant movement or deterioration.

Missing Mortar: Check if any mortar is completely missing from the joints. Gaps where mortar should be are clear indicators of where water can enter and where the brick may be loose.

Spalling Brick: Look at the face of the brick itself. Is the surface flaking, chipping, or crumbling? Spalling is a sign that water has penetrated the brick and frozen, causing the face to break off. This often accompanies loose mortar.

Interior Stains: Check the interior wall corresponding to the rattling spot. Are there water stains, discoloration, or peeling paint on the drywall? This suggests that the compromised mortar has allowed water to penetrate the wall cavity, potentially damaging insulation and drywall.

Loose Debris: Look at the ground below the rattling spot. Are there small pieces of mortar or brick dust? This indicates active deterioration and that material is falling out of the wall.

Why Photos Are Important for Assessment

When you contact EVO SERVICE for brick mortar spot repair for rattling in wind in Lombard IL, providing clear photos can significantly speed up the diagnostic process. We need to see the extent of the damage to determine if a simple repointing job is sufficient or if more extensive stabilization is required. Please include the following in your photos:

• Wide Shot: A photo showing the entire wall section and the location of the rattling spot in context. This helps us understand the height and accessibility of the area.
• Close-Up: A detailed photo of the specific brick and mortar joints that are rattling. Focus on any cracks, missing mortar, or loose bricks.
• Interior View: If there are interior water stains or damage, include a photo of the inside wall. This helps us assess potential water intrusion and the need for interior repairs.
• Video (Optional): If possible, a short video of the rattling sound during windy conditions can help us confirm the issue and its severity.

What a Handyman Can Fix

For most cases of rattling brick mortar, a skilled handyman can perform the necessary repairs. The typical process involves:

Raking Out Old Mortar: The first step is to carefully remove the deteriorated mortar from the joints. This is done to a consistent depth, usually about 2/3 of the joint width, to ensure a good bond for the new mortar. Special care is taken to avoid damaging the surrounding bricks.

Cleaning the Joints: The joints are thoroughly cleaned of dust, debris, and loose particles. This is crucial for the new mortar to adhere properly. Water may be used to dampen the joints before applying the new mortar, which helps prevent the dry bricks from sucking the moisture out of the fresh mix too quickly.

Applying New Mortar: A mortar mix that matches the original in color, texture, and composition is applied. For older homes, a softer, lime-based mortar may be used to ensure compatibility with the existing bricks. The mortar is pressed firmly into the joints to eliminate air pockets and ensure a solid bond.

Tooling and Finishing: Once the mortar has set slightly, it is tooled to match the profile of the existing joints. This not only improves the appearance but also helps to compact the mortar and seal the surface against water penetration.

Stabilizing Loose Bricks: If a brick is loose but not damaged, it may be stabilized by repointing the surrounding joints and ensuring the brick is properly seated. In some cases, a small amount of mortar may be injected behind the brick to fill the void and prevent movement.

When a Specialist Is Needed

While many rattling brick issues can be handled by a handyman, some situations require the expertise of a masonry specialist or structural engineer. These include:

Large-Scale Structural Movement: If the rattling is accompanied by significant bulging, leaning, or large cracks that extend across multiple courses of brick, it may indicate a foundation problem. In such cases, a structural engineer should assess the home before any masonry repairs are attempted.

Historic Preservation: If your home is a historic property in Lombard, there may be specific guidelines for mortar composition and repair techniques. A masonry specialist with experience in historic preservation can ensure that the repairs meet these standards and do not damage the historic character of the home.

Extensive Water Damage: If the interior of the wall is severely damaged by water, with rotting wood framing or compromised insulation, a more extensive repair may be needed. This could involve removing sections of the interior wall to dry out and replace damaged materials, which may require a general contractor or water damage restoration specialist.

Prevention and Maintenance Tips

Once the rattling brick mortar has been repaired, there are steps you can take to prevent future issues:

Regular Inspections: Inspect your brickwork at least once a year, preferably in the spring after the winter freeze-thaw cycles. Look for new cracks, missing mortar, or spalling bricks. Early detection can prevent small problems from becoming major repairs.

Proper Drainage: Ensure that water is directed away from your home’s foundation. Gutters and downspouts should be clean and functioning properly, extending at least 5 feet away from the house. Poor drainage can lead to water pooling around the foundation, which can seep into the brickwork and cause damage.

Sealing: Consider applying a breathable water repellent sealant to your brickwork. This can help prevent water from penetrating the mortar and bricks, reducing the risk of freeze-thaw damage. However, it is important to use a sealant that allows moisture to escape from the wall, as trapping moisture can cause more harm than good.

Trim Vegetation: Keep trees and shrubs trimmed away from your brick walls. Overhanging branches can trap moisture against the wall and provide a pathway for pests to enter. Roots from nearby trees can also cause foundation movement, leading to cracks in the brickwork.

FAQ: Brick Mortar Rattling in Wind

Q: Is a rattling brick dangerous?
