How are Masonry Cracks Repaired? (Your Complete Guide)

4 min read

Masonry cracks can be caused by a variety of factors, including bad weather. When it rains, the water can seep into the cracks and freeze, causing them to expand and break apart the masonry. Poor quality masonry. If you are using cheap or low-quality masonry, it may not be strong enough to withstand any kind of pressure or weight.

When this happens, the masonry will break apart and create cracks in your home’s wall. Inadequate support for heavy items like furniture and appliances. For example, if you have a heavy item like a refrigerator sitting on top of a wall without being supported by something underneath it like wood beams or cement blocks, then this will put stress on that particular part of your wall, which could cause it to crack under pressure from those objects sitting above them (or even just from their own weight alone).

Different Types Of Masonry Cracks

There are a number of types of cracks that can occur in masonry that require repair. Some are more serious than others, but all of them should be inspected by a professional before they’re repaired.


Cracks that run vertically up or down the wall: These are called “dovetail” or “wedging” cracks, and they’re usually caused by shrinkage as a result of water damage. They can also be caused by poor casting techniques or improper curing procedures.


Cracks that form parallel to the wall surface: These are called “lateral” cracks and are usually due to poor workmanship or improper curing procedures. They’re also common in older buildings because they were built using inferior materials and techniques.


Cracks that form around corners: These are called “corner shear” cracks and happen when two pieces join together without being properly supported (usually with wire mesh). Corner Shear cracks can be repaired if they don’t go all the way through the wall, but if they do, the entire wall will need to be replaced. If you want more resources, be sure to visit us at

Repair Methods For Small Masonry Cracks

Masonry cracks are the bane of many homeowners’ lives. While they can be a sign that your house is aging, more often than not they are a result of poor construction practices, improper installation, or just general wear and tear. There are several ways to repair masonry cracks, depending on where they are and what kind of material your home is made out of.


If you have a crack in the mortar between bricks, there are several methods for repairing it. First, clean out any debris from the crack using a wire brush or similar tool. Next, you’ll want to apply an adhesive such as masonry cement to fill the gap between the bricks. Finally, use joint tape or mortar mix to cover up your repair so that it blends in with the rest of your home’s exterior walls without leaving any gaps that could cause water damage over time.


If you have cracks in brick or stone walls themselves instead of mortar joints between them, then there are still some good options available for repairing them depending on how bad they are:


If they’re small cracks less than 1/4 inch wide, then simply filling them with caulk may be enough to keep water out of your home while also making things look better aesthetically speaking

Repair Methods For Large Masonry Cracks

If you have a large masonry crack in your wall, there are several masonry repair methods that can be used to fix it:


Drywall patching: This involves making an incision in the drywall and filling it with a patching compound. This method is inexpensive and can be done by an amateur. However, if the cracks are deep or wide enough, this method may not be effective.


Mortar patching: This involves using mortar to fill in the cracks. Mortar is more likely than drywall to correctly bond with the masonry substrate and provide a secure repair. This method is also inexpensive but can take some time to complete due to drying time requirements for mortar. It can also be messy if not done correctly.


Epoxy injection: Epoxy injection is typically only used for large cracks since it requires special equipment and training to perform properly, but it does offer better bonding than other methods due to higher viscosity compared with conventional caulking materials such as polyurethane caulk or silicone caulk which require more skill than applying epoxy injections because they need less skill because they are injected into cracks rather than applied with brushes or rollers

Cost Of Masonry Crack Repair

The cost of masonry crack repair depends on a few different factors, including the size and location of the crack, how many cracks need to be repaired, and if you need to hire a professional to do the work.


The average cost of masonry crack repair ranges from $50 to $200 per linear foot. Masonry contractors generally charge by the square foot, so this would depend on how many square feet are affected by the damage.


If you need a professional mason to fix your cracks, expect to pay between $150 and $500 per hour, depending on where you live. This will include materials as well as labor costs.
