New Brick Basics: Maintenance, Care, and Cleaning

Durability and longevity are important

By Joyce L. Carroll

From stately colonials to simple ranches, brick has remained as a popular building material for centuries. Its energy efficiency and aesthetic appeal are an added bonus in terms of resale value. Brick is relatively maintenance free, but occasional cleaning, spot checks for water damage, and repointing are necessary in order to ensure long-lasting structural integrity.

The least aggressive approach should be your first plan of action when it comes to cleaning brick. Just like soiled clothing, different types of dirt on your home's exterior will require a different cleaning agent. Once a year use a garden hose, with a spray nozzle, or a spray bottle to remove any loose dirt.

If a particular side of your home receives little to no sunlight and the nearby vegetation is damp, be on the lookout for moss, mold, or mildew growth. A solution of one cup of bleach mixed with a gallon of water can be applied with a scrub brush can be used to clean most problem areas. Use a natural or synthetic bristle brush — wire brushes leave traces of steel behind that will rust and discolor the bricks. Before applying a bleach solution to brick, give the area a thorough soaking. This will help prevent the brick from absorbing the bleach.


Avoiding Water DamageWater damage is caused by one of two conditions: splash back or rising damp. In splash back, the continually of rain beating against the brick soaks into the mortar, causing the mortar joints or the bricks to crack. Rising damp results when ground water seeps up from below, leaving behind what is called a tide line. The moisture above the tide line will eventually evaporate, but the salt crystals that remain will, over time, cause the bricks and mortar to break down. Freezing and thawing cycles can accelerate damage to water-soaked brick, so repairing problems early will prevent more extensive repairs in the future. Look for water damage on an annual basis, and budget for some possible repointing every five to ten years.
