No doubt about it, brick and stone give a house a classic look like no other material. One good thing about brick is that it doesn”t need painting; problem is that brick gets dirty and needs to be cleaned from time to time to maintain its looks and its longevity, Things like pollution, wind borne dirt, mold and mildew can all contribute to the deterioration of your external brick.With a standard residential cleaning, we will scrape down anything that is conspicuous on the surface. It”s better to use a light spray pattern and low pressure with residential brick surfaces. High pressure washing is good for driveways, but sometimes tight pattern can leave the brick marred. If there are more stains left after the cleaning, a brushing can remove them.Not all brick pressure washing is for old brick. Often it”s necessary on new buildings that need to be spruced up. Mortar can be messy to work with, and often the bricklayers get it on the surface of the bricks. We start off with a preliminary wetting too loosen the cement. Then special detergents are applied under pressure to remove foreign materials from the surface. Problems arise because you want to get the mortar off the surface, but you don”t want to erode the mortar between the bricks, obviously. The pre-soaking loosens whatever is on the surface, and additionally keeps the detergents from seeping into the brick. Detergents applied to a surface that is not properly soaked can discolor the brick or remove any finishes it might have. In the case of historic buildings, will require more delicate handling, as the mortar will be more brittle and the brick generally dirtier.
