7 Common Masonry Problems in Older Homes — What Brookfield, IL Homeowners Should Watch For

Older homes in Brookfield, IL, carry character and history, but masonry that has stood for decades can develop problems from weather, materials, and shifting foundations. Recognizing common masonry issues early helps homeowners plan repairs, preserve curb appeal, and avoid more costly structural damage. This guide outlines seven common masonry concerns in older residences in the Brookfield area and what to expect when addressing them.

1. Cracked or Spalling Brick

Freeze-thaw cycles in the Chicago area can cause bricks to spall (surface flaking) or develop cracks—repeated moisture absorption followed by freezing creates internal stress that weakens the brick face. Cracked bricks allow more water penetration, accelerating deterioration and sometimes affecting underlying structural components.

2. Deteriorated Mortar Joints

Mortar ages faster than brick. Over time, it can crumble, pull away from joints, or wash out, weakening the bond between bricks or stones. Mortar loss creates gaps that allow water in and can compromise load transfer across a wall. Repointing by a trained mason is typically required when joints have lost their integrity.

3. Efflorescence and Staining

White, powdery deposits (efflorescence) often appear on masonry surfaces when soluble salts come to the surface as water evaporates. While sometimes primarily cosmetic, persistent staining can indicate chronic moisture issues—poor drainage, rising damp, or faulty coatings—that should be assessed to prevent long-term damage.

4. Settlement and Foundation-Related Cracks

Older foundations may settle unevenly, causing vertical, diagonal, or stair-step cracks in masonry walls. Small hairline cracks are common, but wider gaps, misaligned door/window frames, or separating walls can indicate more serious settlement or foundation movement that may require a structural evaluation.

5. Bulging or Bowing Walls

Walls that bulge or bow outward are a red flag. Failing ties or anchors, deterioration of interior structural elements, or excessive lateral loads can cause this condition. Bulging often requires prompt professional assessment, as it can indicate that a wall is losing its ability to carry loads safely.

6. Water Intrusion and Poor Flashing Details

Missing or failing flashing around chimneys, window sills, and roof-wall intersections allows water to enter behind masonry veneers and into interior spaces. Signs include damp spots, rust stains, or interior water stains. Addressing flashing and drainage details is essential to prevent hidden rot, mold, and continued masonry decay.

7. Chimney Deterioration

Chimneys are particularly exposed and often exhibit multiple issues, including cracked crowns, mortar loss, leaning stacks, and damaged caps. Because chimneys are vertical, they’re more vulnerable to freeze-thaw damage and penetration by water and animals. Neglecting chimney repairs can lead to leaks, smoke problems, or even collapse.

A Few Practical Signs to Watch For:

• Cracks wider than 1/8 inch, especially stair-step patterns in masonry block or brick

• Repeated or widespread spalling or flaking of brick faces

• Persistent damp spots or interior stains near masonry walls

Inspection and Repair Considerations:

• Hire a licensed masonry contractor or structural engineer experienced with historic or older homes in Brookfield, IL. They can assess causes versus symptoms and recommend appropriate remediation.

• Prioritize moisture control, proper flashing, and drainage improvements before cosmetic work. Fixing the source of water intrusion prevents recurring damage.

• Repointing should use mortar compatible with historic masonry (strength and permeability considerations) so replacement mortar doesn’t harm original bricks.

• For significant movement, bulging, or foundation concerns, obtain a structural evaluation rather than relying on surface repairs alone.

Preserving masonry in older Brookfield homes often requires specialized knowledge of historic materials and the effects of the local climate. Early professional evaluation and timely, appropriate repairs protect both the character and structural integrity of your property.
