-
Cracked mortar joints: Over time, the mortar between the bricks may crack due to weather exposure, water penetration, and normal wear and tear. These cracks can cause the bricks to shift and loosen.
-
Loose bricks: If you notice that some of the bricks in your wall are loose or wobbly, this may indicate that the mortar has deteriorated, and the bricks are no longer adequately supported.
-
Water penetration: If you notice water stains or damp patches on the inside walls, it could be a sign that the mortar has lost its effectiveness and is allowing water to penetrate the bricks.
-
Weathered mortar: The mortar between the bricks can become weathered and eroded over time, leading to an uneven surface and an unsightly appearance.
-
Discoloration: Discolored or darker areas on your brickwork can indicate that the mortar has deteriorated and may need repointing.
-
Soft mortar: If the mortar between the bricks feels soft or crumbly to the touch, it is a clear sign that it has deteriorated and is no longer providing the necessary support to the bricks.
