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.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

Mortar is a mixture of sand and cement that binds materials, such as bricks, stones, and concrete blocks, together. Think of it as the glue that fills in the gaps between bricks and stones, then seals them in place to prevent damage or deterioration. Mortar also helps spread the load across a wall or structure, keeping cracks and shifting at bay.

In certain cases, such as when dealing with surfaces like concrete rather than brick, grout can be used instead of mortar. Grout tends to be more convenient to work with on non-masonry surfaces. However, many experts suggest using mortar whenever possible, as it provides stronger adherence to the bricks and results in a more textured appearance.
