How to Remove Soot, Dirt and Atmospheric Staining From Brickwork?

Brickwork is essential, especially for traditional and older homes in London. They give properties a distinctive character. However, over time, this brickwork becomes exposed. They start accumulating dirt. Soon, you will notice organic growth and pollution from traffic leaving stains on the brickwork and making it look dark and tired. Older buildings are particularly affected because this dirt and dust build up over years across the surface. 

Cleaning brickwork will brighten it, but it won’t remove soot, dirt, and atmospheric stains. Professional assessment is necessary for brick cleaning in London. They work wonders on older, delicate or heavily stained masonry. 

What causes staining on brickwork?

Brick walls are continuously exposed to weather and pollution. Over time, dust and soot settle on the surface and lead to discolouration. 

Soot and pollution

Soot from fireplaces and heating systems accumulates and deposits as dark patches on brick façades. You will find it particularly around windows, chimneys, and other areas where these particles settle. 

Dirt and dust

Wind generally carries the dust and other dirt particles and deposits them on the brickwork. When rain falls, these deposits stick to the brickwork, creating streaks and a discoloured surface.

Organic staining 

Moist areas often encourage organic growth like algae and moss. These deposits create green, black, or brown marks that become noticeable on shaded walls. 

How is brickwork cleaned?

Assessing brick first

Before cleaning starts, professionals inspect the brickwork. Professionals check the brick texture. They check whether the bricks are hard or soft. If the mortar joints are sound, repairs may be enough to restore the condition. They will check the small test area to understand how the brick responds. 

Choosing suitable cleaning techniques 

Different contaminants are removed differently. Some techniques include gentle washing methods that help remove loose surface dirt. Specialised techniques can remove unwanted deposits. 

Why should high-pressure cleaning be used carefully on brickwork?

Pressure washing may seem like a simple way to clean a dirty wall. However, excessive pressure can damage the brickwork. It can erode softer bricks. It can also damage mortar joints and force water into broken or damaged brickwork. 

Protecting the brick surface is essential. Aggressive high-pressure cleaning removes this surface and leaves the masonry more vulnerable to future deterioration.
