Masonry Repair Services in Oak Lawn, IL: Top Contractors

Look for visible cracks in mortar, crumbling or missing mortar sections, or loose bricks. Another sign is efflorescence—a white, powdery substance on the brick surface, which indicates water penetration. Addressing these issues early prevents more costly structural damage later on.

Joints primarily fail due to moisture penetration, freeze-thaw cycles, and natural building settlement or movement over time. Inferior mortar or sealant can also degrade quickly. Using a protective cap over the sealant can absorb movement and shield the joint, drastically extending its life.

A professional masonry repair using high-quality materials should last for decades. The longevity depends on the craftsmanship and the products used. Incorporating a flexible joint protection system can significantly extend the life of the repair by protecting the sealant from UV exposure and movement stress.

Sealant is the primary barrier against water in a masonry joint. A joint protection system, like WEATHERCAP®, is a physical cap (typically soft lead) installed over the sealant. It shields the sealant from the elements and absorbs stress from building movement, preventing the sealant from failing prematurely.
