Mortar plays a critical role in masonry construction. It bonds bricks together, distributes weight, and helps protect structures from moisture and weather damage. Over time, however, mortar can begin to crack or deteriorate. When this happens, experienced masonry contractors near me Winnetka are often needed to restore the strength and appearance of the brickwork.
One of the most common causes of mortar cracking is natural aging. Mortar is designed to last many years, but exposure to wind, rain, and temperature changes slowly weakens the material. As the mortar dries out and loses flexibility, small cracks may begin to appear.
Another major factor is moisture infiltration. Water that enters masonry joints can weaken the mortar over time. During cold weather, this trapped moisture may freeze and expand, forcing the mortar apart and causing visible cracks.
Structural movement is another common reason mortar joints fail. Buildings naturally shift slightly as foundations settle or temperature changes cause materials to expand and contract. This movement can place stress on mortar joints, eventually leading to cracks.
Poor installation can also contribute to mortar problems. If the original mortar mix was not prepared properly or applied incorrectly, it may deteriorate faster than expected. In these cases, masonry contractors may recommend more extensive repairs to correct the underlying problem.
To fix cracked mortar, professionals often perform a process known as tuckpointing. This involves carefully removing damaged mortar from the joints and replacing it with new mortar that closely matches the original color and texture. Tuckpointing not only strengthens the wall but also restores its appearance.
In cases where the damage is severe, individual bricks may also need to be replaced. Masonry contractors can carefully remove damaged bricks and install new ones while preserving the integrity of the surrounding structure.
Regular maintenance and timely repairs are key to extending the life of masonry. Addressing cracked mortar early can prevent moisture intrusion and structural weakening. Professional masonry contractors ensure that repairs are performed correctly so the structure remains stable and durable for many years.
