Repair Crack In Brick Foundation
Make sure the grading around your foundation is good and your downspouts are draining away from the home. Clogged gutters may not seem like a foundation threat, but they are! This type of preventative maintenance can also protect your brick foundation from erosion, hydrostatic pressure, and water intrusion.

Before we begin, please be confident in the makeup of your foundation structure. Most homes built since the 1950s have concrete foundations. Builders often add a type of decorative outer layer -a brick veneer- to cover the concrete and add to curb appeal.
In the photo above, you can see the porch veneer is made of stone (not brick). But the signs of settling are clear and easily spotted; a brick veneer cracks in the same ways. Piers are usually the best method for settling foundations, but sometimes porches require both piers and slabjacking.
We understand that entering a crawl space can be unpleasant, and it may not be possible for you to do so. But if you have cracked brick walls, or suspect you need foundation repairs, please have a professional evaluate your home.
We highly recommend waterproofing for crawl spaces, and not just for foundation repair purposes. A wet crawl space can lead to sagging floors, rotting insulation, and mold or other biological growth.
I have some cracks in the foundation of the house I am about to buy. The house is 100 years old, there doesn't seem to be water leaks. The cracks don't look to be offset.Attached is the picture (sorry for the quality, I got it from inspector). This is townhouse and there are two houses on the sides which I believe are touching my foundation on the outside.
Begin by cleaning all crumbling brick and mortar from the crack with a cold chisel and sledgehammer. Where the crack runs through a brick or a concrete block, use a brick chisel, angled into the crack, to widen and undercut the break.
Enlarge the crack to a consistent width and clean the inside of the crack to its full depth, or as far in as you can reach. Wire-brush the crack, inside and out, to remove debris, then flush it thoroughly with water from a garden hose. Cracks that affect only a single layer of brick can be filled with mortar. Mix a small amount of mortar according to the directions on the package. Spread a little mortar on a scrap of corrugated cardboard, where it will dry quickly and reveal its true color.
Mix enough mortar to fill the crack. Spray the crack thoroughly with the garden hose. Fill the crack with mortar using a small, sharp trowel to force the mortar into the full depth of the crack. Treat the crack as one long joint, filling cleaned-out joints and the gaps in broken bricks or concrete block evenly all along the crack.
When the crack is solidly packed with mortar, finish the surface with a jointer and the trowel. Match the old joints where the crack follows a joint: trowel the mortar to match the surface where the mended surface is block or brick.
You have cracks. Which everyone is telling you is not a problem. You can repoint the brick and the surface cracks will disappear at least until the wall shifts again, at which point they'll telegraph back out. You can decide what you want to do but the consensus seems to be that you don't need to do anything to them. The consensus also seems to be that you may have water concerns, but based on the photos I would say you probably don't.
Homeowners love brick walls for their durability and the aesthetic they can add to a home. However, many people assume incorrectly that cracks in brickwork are a natural part of the aging process when they are, in fact, a strong signal that your foundation is experiencing failure of one type or another. Cracks in bricks are not something a homeowner can fix with a DIY approach, but understanding the three types of cracks possible and what they indicate can help you better communicate the issue to a professional foundation repair company like The Foundation Specialists.
Cracked bricks on a house are the most common sign of foundation settlement. If a house has stair-stepped cracks in the exterior brick, it is likely that the footing has broken and is settling. But just because there are cracks, does not guarantee that the house is settling.
Once you know whether the cracks are being caused by differential settlement or swollen lintels, you can proceed with addressing the source of the problem. If a crack is caused by the foundation settling, the soil supporting the footing must be addressed. Any settlement is primarily a problem with the soil once the foundation is broken or cracked. If a crack is caused by the swelling of a metal lintel, it should simply be replaced. New lintels are typically galvanized which means the metal was treated with zinc, to prevent future oxidation and damage from moisture.
As with most repairs, the best solution depends on the circumstances. Unfortunately, in the case of foundation settlement, most of the issue lies with the inadequacy of the soils so the best solutions bypass the soil directly underneath the cracked footing.
The only way to know the cost of repairing cracks in a brick wall is to contact an experienced foundation repair contractor and request an inspection and estimate. Most contractors will do the inspection for free.
These types of cracks almost always indicate foundation failure. What this typically means is the soil under and around your house is pushing against your foundation and forcing the walls inward. This inward force is causing your walls to bow in towards your home, thus creating the horizontal crack. If you were to leave this problem alone, the crack will continue to grow, resulting in a bowed wall which is more likely to collapse. If a foundational wall collapses the rest of your house is likely coming with it.
These cracks, much like horizontal cracks, are typically early indicators of foundational trouble. These types of cracks usually show that the ground your foundation currently sits on is shifting. This shift causes your home to settle abnormally, thus producing cracks in your brick foundation. This change in soil causes vertical cracks and other issues such as cracked drywall or sagging floors.
This type of crack is significantly less worrisome than a horizontal crack, but can still pose a threat to your basement or home. Stair-step cracks are usually found on the exterior walls of a brick and mortar house, above the foundation. They signify movement in the foundation and require repairing by a foundation repair company such as . The stair-stepping crack is caused by separation in the brick by shifting foundations. For older homes with leaky basements, this type of foundational crack is often the reason.
Cracks in bricks may allow water to enter the materials resulting in further deterioration. The water may also cause the cracks to worsen when it freezes and thaws as the water contracts and expands based on the temperatures. Any brick along your home whether on walls, steps, foundations, or chimneys may experience this serious problem. However, the problem for cracked bricks found along the upper parts of the house may lie with the foundation.
When the foundation experiences an issue, it may settle and shift. When this happens, the moving foundation may cause cracks in the brickwork as well as sagging drywall and uneven floors. A foundation problem may also cause the doors on cabinets and rooms to swing open or shut on their own. The structural stability of your home becomes compromised and may eventually lead to a collapse.

No. Brick and other masonry work are designed to last for many generations. While the mortar between the bricks may wear away from age and weather, the cracked bricks are not a normal occurrence for Virginia and Northeastern North Carolina homes. You should always investigate even the smallest cracks as they could be the first indicator of a sinking foundation or serious structural damage to building supports.
Think of wall cracks as your home telling you that there is a problem. They may be the most visible sign that there may be foundation failure. The reason that the foundation or building supports are failing may be difficult to discover and could come from a variety of sources. Having the professionals at BAY Crawl Space & Foundation Repair evaluate the foundation and your home may help to discover the possible issues.
In addition, the mortar and grout used between the bricks consist of concrete. Concrete is porous. It absorbs moisture as it expands in the summer during warm weather and then contracts in the winter. Mortar cracks form that may shift and loosen the bricks.
All of the soil compacted around the foundation and walls of the home have enormous amounts of load force. When designed correctly, the foundation ensures that the load stays in place. Unfortunately, the walls of the home may buckle because of too much load. If the load force is more than the walls can handle, buckling occurs as the walls sag or lean inward. Foundation cracks may also occur when too much weight becomes placed onto the walls of the home.
Even the condition of the soil may negatively impact the brickwork. Soil that is too porous, not compacted, or overly saturated with water may allow the foundation to shift and make brickwork cracks. The soil may wash away due to water from misdirected downspouts, gutters, leaking pipes, and standing pools of water along the perimeter of the home. Sub-surface water could wash away the soil located around footings. Another factor that leads to soil problems may involve moist soil drying out and shrinking.
