There are several reasons why various cracks may appear in the interior or exterior walls of buildings. Some are superficial and can be repaired very easily, while others are deeper, and the repair process may have to be approached differently.

Construction materials (brick, concrete, etc.) have different behaviors over time and are exposed to various factors that may lead to the appearance of cracks.

The causes can be multiple. For example, cement is more sensitive to temperature variations and can crack more easily than other materials, but these cracks are typically superficial.  Also, cracks in the Connecticut masonry are often caused by drying contractions of the plaster. These cracks are the only ones that do not affect the stability and strength of a building, and usually occur:

• at the joints between the walls and beams;
• at the joints between two different materials, for example masonry and drywall;
• on the route of certain conductors or pipes embedded in the plaster;
• at the top of the doors.

But there are also subsidence cracks, or cracks caused by earthquakes, which can be remedied only with the help of a technical expert or a construction engineer, because, in this case, there are risks of improper masonry restoration that go beyond the unsightly appearance; they may affect the stability of the building and the safety of those who live or work there.
