Brick Cleaning and Sealing
Brick collects dirt, algae, soot, rust and mortar haze over the years. We clean it with methods matched to the brick, using low pressure and the right cleaners, then apply a breathable sealer where it makes sense so the wall sheds water without trapping moisture.

About brick cleaning and sealing
Is pressure washing safe for brick?
High pressure can damage soft brick and mortar. We use low pressure and cleaners suited to the brick, and test a small area first.
Do I need to seal my brick?
Not always. Sealing helps some walls and patios, but a sealer must be breathable. We explain whether it makes sense for yours.
How long does a cleaned wall stay clean?
It depends on shade, trees and moisture. Shaded north walls grow algae sooner, and a sealer plus a yearly rinse can help.
