Drilling into brick or mortar requires the use of a masonry drill bit. Masonry drill bits appear similar to standard drill bits except for the leading tip of the bit. The tip has a bulky carbide arrow-shaped end slightly larger than the rest of the bit shaft. Standard or high-speed drill bits designed for making holes in wood or metal don’t have the ruggedness or design shape you need to drill into brick. They may not go through the brick at all, and if they do, they’re more likely to overheat, crack, or dull before you finish drilling.

Minor hairline cracks in mortar are normal over time. This is a natural occurrence as bricks settle. You should worry about cracks in brick if you see vertical cracks that widen as they move up, stair-step cracks, L-shaped cracks, or deep horizontal cracks. These are all more serious signs of foundation damage.

No, it’s not recommended to attach shutters to brick without drilling. Brick is dense and built to last, so adhesives and shortcut methods don’t usually cut it. Even heavy-duty glue struggles to hold up over time—especially against wind, moisture, and temperature changes. Most no-drill options are made for materials like vinyl or wood, not solid masonry. Skipping the drill might seem easier, but it puts your shutters—and anything below them—at risk. For a secure, lasting install, drilling is the way to go. It takes more effort up front, but the result is safer and more reliable.

Drilling into brick doesn’t have to be a dangerous project if you prep and approach it with the right tools and techniques, but it does come with risks if it’s not done correctly. It can lead to significant issues, such as damaging the brick or affecting the wall’s structural integrity. Applying too much force can crack or chip the brick, while incorrect placement might compromise its load-bearing strength.
