If your old bricks are in decent condition and you have the space to store them where they’ll be protected from the elements, keeping old bricks is often worthwhile. You’d spend anywhere from $70 to a few hundred dollars to have them removed from your property, in which case you won’t be able to use them for future projects. Holding on to old bricks in good condition means you can use them later for other DIY projects, potentially saving yourself some money on disposal and new materials down the road.

A mason lays brick or stone together, sometimes with mortar in between the bricks and stones, and sometimes without mortar, also called a dry-stack or surface bonding. Examples of work masons do include:

• Brick, stone, or cement block houses and buildings

• Freestanding stone or brick walls

• Chimneys with wood-burning fireplaces

• Cement block basement or crawl space walls

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.

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.
