efflorescence on brick in Tyrone

In Tyrone, this comes up on estate lots and newer houses on larger tracts. Long drives carry clay onto courts that were poured to look bare. New brick and retaining walls show it more. A white haze low on a wall, after rain, is the pattern.

Big roofs fill gutters faster than a one-story cottage, and the height is a lift conversation.

Mildew is green or black and biological. Efflorescence is white, crusty, and chemical in the mineral sense: salts dissolved inside the masonry, carried out, and left when the water evaporates. Killing it is the wrong idea. It was never alive. A mild, appropriate cleaning can remove the crust that is already on the face. If the wall keeps wicking water, the crust returns.

We will not attack historic brick with muriatic acid because a homeowner wants it “bright.” Acid on the wrong brick is how faces dissolve. If acid is even on the table, it is a specific masonry decision, named in the quote, not a default.

If the white showed up with a leak, a bad cap, or irrigation on the wall, fix the water or you will hire the wash again. We will point at the likely source. We will not rebuild the wall.

The full explanation, without the town attached, is the white crust on brick is salt, not mildew article. The town does not change the chemistry. It changes the houses, the shade, and the clay.
