Masonry gives homes and commercial properties durable, attractive surfaces that can last for many years. Brick walls, stonework, concrete steps, stoops, patios, walkways, retaining walls, and other masonry features are built to withstand regular use and outdoor exposure. However, they are not maintenance-free.

Moisture, settlement, impact, age, drainage problems, and New Jersey’s repeated freeze-and-thaw cycles can gradually affect mortar joints, concrete surfaces, bricks, stones, and the structures supporting them. Small cracks or loose materials may appear minor at first, but they can become more extensive if the cause is not addressed.

Understanding common masonry problems can help property owners know when to request a professional assessment.

Why Masonry Deteriorates

Masonry systems are made from durable materials, but they remain exposed to weather throughout the year. Water can enter small cracks and porous surfaces. When temperatures fall, trapped moisture may freeze and expand, placing pressure on the surrounding material.

Repeated freezing and thawing can contribute to cracking, flaking, loose mortar, and surface deterioration. Drainage problems can make the situation worse by allowing water to collect near steps, patios, walls, and foundations.

Settlement and movement can also create cracks or uneven sections. The cause and significance of a crack depend on its location, direction, width, and whether it continues to change.

Cracked or Missing Mortar Joints

Mortar holds individual bricks or stones together and helps distribute loads throughout a masonry assembly. Over time, mortar joints can crack, crumble, erode, or separate from the surrounding units.

Deteriorated joints may allow additional moisture to enter the masonry. If the bricks or stones remain in serviceable condition, removing damaged mortar and replacing it through repointing may help restore the joints.

The replacement mortar should be compatible with the existing masonry. Using an unsuitable material can create performance or appearance problems, particularly on older buildings.

Cracked Bricks and Stone

Individual bricks or stones can crack because of moisture, movement, impact, weather exposure, or pressure within the masonry system.

One cracked unit may be an isolated issue. Cracks that continue through several bricks, follow a stair-step pattern, or return after previous repairs may indicate movement that requires closer evaluation.

Replacing damaged materials without considering the cause may only provide a temporary cosmetic improvement.

Spalling and Flaking Surfaces

Spalling occurs when the outer surface of brick, stone, or concrete flakes, chips, or breaks away. It is often associated with moisture entering the material and expanding during cold weather, although age, unsuitable coatings, impact, and material defects may also contribute.

Once the protective surface begins to deteriorate, the material can become more vulnerable to continued weather exposure. A masonry contractor can evaluate whether the affected units can be repaired or should be replaced.

Problems With Concrete Steps and Stoops

Front steps and stoops experience foot traffic, rain, snow, ice, deicing materials, and changing temperatures. Common problems include:

• Surface cracks
• Chipped or broken edges
• Loose bricks or stones
• Deteriorated mortar joints
• Uneven steps
• Separation from the building
• Water collecting on landings
• Damaged sidewalls or rail attachment areas

Minor surface damage may be repairable. More extensive deterioration, movement, or instability may require rebuilding part or all of the structure.

Because steps and stoops are used frequently, loose or uneven areas should be assessed before they become more difficult to navigate.

Patio Cracks and Uneven Areas

Patios can develop cracks, settlement, loose pavers, open joints, and low areas where water collects. These problems may result from insufficient base preparation, soil movement, drainage issues, root growth, erosion, or normal aging.

A limited repair may be possible when only a small section has moved. Widespread settlement or drainage problems may require lifting and rebuilding a larger area.

When installing a new patio, proper base preparation, grading, edge support, material selection, and drainage planning are essential. A well-planned patio should suit the property’s layout while directing water appropriately.

Walkway Deterioration

Walkways often experience many of the same problems as patios and steps. Cracks, loose pavers, raised edges, and sunken sections can develop over time.

Water flowing from gutters, downspouts, sloped landscaping, or nearby paved areas may wash out supporting material beneath a walkway. Tree roots can also contribute to movement.

Repairing the visible surface without correcting the underlying cause may allow the problem to return.

Retaining Wall Concerns

Retaining walls hold back soil and must manage pressure and drainage behind the structure. Visible concerns can include:

• Leaning or bowing
• Horizontal or stair-step cracks
• Loose stones or blocks
• Separated sections
• Water staining
• Soil washing through joints
• Settlement near the base

A retaining wall that is leaning or moving should be evaluated promptly. Replacing surface materials alone will not correct problems caused by inadequate drainage, base movement, or excessive soil pressure.

Chimney Masonry Damage

Chimneys are especially exposed to rain, snow, wind, and temperature changes. Deteriorated mortar joints, cracked crowns, loose bricks, and damaged flashing can allow moisture to affect the masonry and surrounding roof areas.

Because much of a chimney is above the roofline, damage may not be easy to see from the ground. Professional evaluation can help identify visible concerns and determine whether repointing, brick replacement, crown repair, or more extensive rebuilding should be considered.

Repair or Rebuild?

The appropriate masonry service depends on the material, location, extent of deterioration, and underlying cause.

Repair may be suitable when damage is limited to particular joints, units, or surface areas and the surrounding structure remains stable. Rebuilding may be more appropriate when masonry is loose, significantly displaced, extensively deteriorated, or affected by recurring movement.

A professional assessment should consider more than appearance. Drainage, base preparation, adjoining structures, movement, and exposure can all influence the recommended work.

Protecting Masonry From Future Damage

Regular observation can help property owners notice changes before they spread. Look for new cracks, loose mortar, displaced materials, drainage problems, and areas where water remains after rain.

Keeping gutters and downspouts functioning properly may help reduce unnecessary water exposure around masonry. Snow and ice should be managed carefully, and products used on concrete or masonry should be suitable for the material.

Applying paint, sealant, or a surface patch is not always the correct solution. Some treatments can trap moisture or hide deterioration without correcting it. Ask a masonry professional which maintenance approach is appropriate for the existing material.
