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.

While painting can certainly change the look of a chimney, you should think twice about giving your brick chimney the old landlord special.

Painting brick is porous, meaning it’s full of tiny holes that can soak up moisture. Those holes also allow it to dry, though. So, when you paint it, you trap any moisture inside, providing an opportunity for mold, mildew, and water damage.

Paint also shows wear faster than naked brick. This means that once you paint a brick surface, you’ll have to keep painting it to maintain a clean look. A paint job is also harder to undo on brick because of its porous nature. Once you paint it, it’s hard to go back without some serious power washing—another added cost.

Yes, masonry is more expensive than concrete because the labor is much more involved. With masonry, your expert will build your project from the ground up, one piece at a time, ensuring they use the proper amount of mortar or grout during construction and keeping the project level or plumb. Pouring concrete can also be labor-intensive, but it’s a bit less involved. It requires building a mold, pouring the concrete, and letting it cure. The less intensive labor makes concrete a more affordable option in most cases.

Yes, brick can breathe through limewash. Limewash is a breathable coating made from natural lime and water, allowing moisture to pass through while providing a protective layer. Unlike synthetic paints or sealants, which can trap moisture within the brick and lead to issues like mold, limewash allows the brick to maintain its natural breathability. This characteristic makes limewash an ideal choice for historic structures where preserving the integrity of the brick is essential.
