Minor hairline cracks in mortar are normal as bricks settle over time. However, deep vertical cracks that widen, stair-step cracks, L-shaped cracks, or extensive horizontal fissures may indicate potential foundation issues. Since mortar doesn't last as long as brick—which can endure for over a century with proper maintenance—it's important to have any concerning cracks inspected by a mason to ensure your home's structural integrity.
Cleaning mortar off bricks removes old stains and debris, ensuring that new mortar adheres properly and lasts longer. Eliminating dust, moss, and lichen helps achieve a strong bond during repointing or mortar application. Professionals typically use a wire brush or pressure washer to clean the surfaces, depending on the level of contamination. If bricks are being completely replaced, cleaning the old material isn't necessary.
With proper care, brick walls can last over 100 years. Regular maintenance, such as repointing mortar every 30 to 50 years, helps preserve the wall's durability and appearance. Consistent upkeep and routine inspections ensure your brick wall remains a strong and valuable part of your home for generations.
If you want to avoid the high expenses of full brick wall restoration, installing fiber cement siding is a viable alternative. Fiber cement siding offers lasting durability and low maintenance while enhancing energy efficiency. This option costs $2 to $6 per square foot and, when installed by a professional, protects against water damage and improves your home’s exterior appearance.
