Brick spalling—which refers to the crumbly, flaky, or pitted appearance that can develop over time—is caused by a few different conditions. These include:

• Climates with constant freeze-thaw cycles

• Use of non-breathable sealants

• High-pressure water cleaning

• Improper installation

While you can’t do anything about the weather, you can preserve your bricks by cleaning them with soapy water and a good old-fashioned scrubbing. Pressure washers may be satisfying to use, but they can eventually wear away the surface of your bricks. If you don’t have advanced-level DIY skills in masonry, you can hire a reputable masonry contractor in your area for your project.

Yes, you can paint stone on the exterior of a house. It’s important to properly prep the stone by cleaning off dirt and debris. You’ll want to apply at least two coats of paint to get the most even and complete coverage. Any pinholes or missed spots, however small, can allow moisture to get into the masonry and potentially cause the paint to blister and peel from the stone.

Yes, it is normal to see some minor hairline cracks in brick or mortar over time, often due to natural foundation settling. However, not all cracks are harmless. You should be concerned and contact a masonry professional for an inspection if you notice cracks that are getting wider or longer, or if new ones keep appearing. Other serious warning signs that can indicate significant structural or foundation damage include large vertical cracks (especially those that widen as they go up), stair-step cracks, L-shaped cracks, and deep horizontal cracks. Factors like temperature changes, moisture, and structural loading can also cause cracks to form or worsen.

On average, a quality exterior brick stain can last between 10 and 20 years, and sometimes even longer. While it will look its best for a minimum of three to five years, its total lifespan depends on several factors. These include the quality and type of stain used, the condition of the brick, and the thoroughness of the surface preparation, such as proper cleaning. Following the manufacturer's application instructions and applying a sealant as a final step is also crucial. The stain's longevity can be affected by your location, climate, and the brick's exposure to harsh weather, high traffic, and other elements. Over time, the stain may begin to fade or look dingy due to weathering, erosion, dirt, and debris. Compared to paint, brick stain generally has a longer lifespan.
