How to Repair a Cracked Brick Wall: A Step-by-Step Guide
Brick walls are strong, but Minnesota’s harsh weather, moisture, and foundation movement can cause cracks over time. If left untreated, cracked brick walls can lead to water damage and expensive structural repairs.
In this guide, we explain how to repair a cracked brick wall and when to call a professional masonry contractor in Minnesota. Murphy Masonry provides expert brick wall crack repair services to keep your home safe and structurally sound.
Understanding the Causes of Brick Wall Cracks
Before starting any brick crack repair, the origin of the cracks must be properly identified. Common causes include the following:
Ground Movement: Brick walls are stressed by shifting soil and settling foundations, leading to cracks in the brick wall.
Water Damage: Moisture infiltration within brick and mortar may subsequently expand or contract the build material from inside, causing weakness to the structural integrity.
Thermal Variability: Among the pressure points as freeze and thaw occur most of the time during the year in Minnesota, pavement creates cracking in brickwork.
Poor Building Practices: Cracks can occur as the structure ages when a wall was not built in proper support.
Assessing the Severity of the Crack
All cracks do not require the same type of repairs. Hairline cracks usually imply cosmetic work, whereas larger cracks may indicate deeper structural issues. Cracks wider than 1/8 inch or that are forming stair-step patterns along mortar joints usually require professional help. Murphy Masonry has the expertise to evaluate the situation and determine the best possible method for Brick wall crack repair in Minnesota.
Gathering Materials for the Repair
To repair a cracked brick wall, you will need the following materials:
Brick mortar mix or caulk for minor cracks
Chisel and hammer for removing loose mortar
Trowel for applying new mortar
Wire brush to clean the area
Safety gear, including gloves and goggles
Step-by-Step Process for Brick Wall Crack Repair
1. Cleaning the Cracked Area
Start by removing any loose mortar or debris from the crack using a chisel and hammer. Then, use a wire brush to scrub the area clean. This helps the new mortar or sealant adhere properly. If dust remains, rinse the area lightly with water and let it dry.
2. Mixing the Mortar
Prepare a mortar mix that closely matches the existing brick and mortar color. If using a pre-mixed mortar, follow the manufacturer’s instructions for consistency. The mix should be firm but workable.
3. Filling the Crack
For small cracks, a masonry caulk can be used. Simply apply it into the crack and smooth it out with a putty knife. For larger cracks, use a trowel to press the new mortar into the gap, ensuring it fills completely. Smooth the surface to match the surrounding area.
4. Allowing the Mortar to Set
Let the mortar cure for at least 24-48 hours, depending on the weather conditions. If working in hot or dry weather, mist the repaired area occasionally to prevent it from drying too quickly and cracking again.
5. Finishing Touches
Once the mortar has set, gently brush away excess material and clean the area to blend with the rest of the wall. If necessary, apply a sealant to protect against moisture.
