To ensure that brickwork remains in optimal condition, it is important to employ the right methods and techniques for cleaning. Professional brick cleaning services possess the necessary expertise and equipment to effectively remove dirt and contaminants without causing damage to the bricks or mortar.

By selecting a reputable and experienced brick cleaning company, clients can be confident that their brickwork will be restored to its original appearance, while also prolonging its lifespan.

Investing in regular brick cleaning not only enhances the visual appeal of a building but also contributes to its overall maintenance and preservation.

When carried out by skilled professionals, brick cleaning can prevent costly repairs or restoration work in the long run. As such, it is sensible for property owners to consider the advantages offered by professional brick cleaning services to retain the value and appeal of their brickwork.

Understanding Brickwork

Components of Brickwork

Brickwork consists of bricks and mortar, which are combined in a specific pattern to create a solid and durable structure. Bricks, typically made of clay or other raw materials, are heated at high temperatures to form strong building blocks. Mortar is a mixture of sand, cement, and water used to secure the bricks together and fill the gaps between them.

Durability and Maintenance Needs

The durability of brickwork depends on the quality of materials used, the workmanship, and the environmental conditions it faces. When properly constructed and maintained, brickwork can last for centuries. 

However, it is essential to address common issues like efflorescence, vanadium staining, manganese staining, and peacocking to ensure the longevity of the structure.

Efflorescence occurs when water-soluble salts within the brick or mortar migrate to the surface, leaving a white, powdery deposit. Vanadium staining is a green or yellow discolouration caused by the presence of vanadium salts in some bricks.

 Manganese staining results in brown or black streaks on brick surfaces due to manganese components. Lastly, peacocking is a term used to describe a unique staining pattern resembling the feathery display of a peacock’s tail.

Common Types of Brick Stains

  1. Efflorescence: A white, powdery substance that forms on the brick surface due to water-soluble salts. It is commonly found in new constructions and can be removed using an efflorescence removal product.

  2. Vanadium staining: Green or yellow discolouration that occurs due to vanadium salts. Avoid using acid-based cleaners, as they may worsen the stain or cause permanent etching. Instead, use a neutral pH cleaner or specially formulated stain remover.

  3. Manganese staining: Brown or black streaks caused by manganese components in bricks. These stains may require a professional brick cleaner or a specified stain removal product.

  4. Mortar staining: This occurs when mortar comes into contact with the brick surface during construction, leaving a haze or residue. To remove it, you can use a proprietary brick cleaning solution or gently pressure wash the area.

  5. Peacocking: A unique staining pattern often seen on brick faces with manganese components. Though challenging to remove, a combination of brick cleaning solution and gentle pressure washing may help.


Reasons To Clean Bricks

Bricks, being a versatile and durable construction material, require regular cleaning to maintain their aesthetic appeal and structural integrity. Numerous factors contribute to the need for regular brick cleaning, including dirt, damage, grime, lichen, moss, and algae.

Dirt and grime accumulate over time on the exterior surface of bricks, leading to a dull and less visually appealing appearance. Cleaning bricks not only restores their original colour, but also improves curb appeal, potentially increasing property value. Moreover, the build-up of dirt can trap moisture within the bricks, causing long-term structural damage.

Lichen, moss, and algae growth on bricks may deteriorate their condition and compromise the structure. These organisms retain moisture, which can lead to weakening and eventual failure of brickwork if left untreated. Regularly cleaning bricks helps prevent the proliferation of these organisms and ensures proper aeration of the brick surface.

Damage to brickwork may occur due to weathering, which often causes crumbling, staining, efflorescence, and corrosion of mortar joints. Preserving the integrity and appearance of brick structures necessitates periodic cleaning to remove damaged sections and prevent exacerbation of the problem.

Brick cleaning delivers both immediate and long-term benefits. In the short term, it boosts the visual appeal of structures and minimises the risk of additional wear and tear. Over the long term, regular cleaning helps prolong the lifespan of brickwork by eliminating contaminants and damage that can weaken the structure.

Brick Cleaning Methods

There are various methods professionals can use to clean bricks effectively. We’ll discuss three main techniques: Pressure Washing, Chemical Cleaning, and Soft-Washing.

Pressure Washing

Pressure washing is a popular method for removing dirt, grime, and stains from brick and stone surfaces. It involves using high-pressure water to blast away accumulated debris. The process begins by applying water to the brick surface, loosening dirt and grime. The cleaning equipment then utilizes a high-pressure jet of water, which effectively removes unwanted material from the brick’s surface.

This method is particularly effective for cleaning exterior brickwork and restoring the appearance of buildings or walls. However, it is essential to use the correct pressure settings and distance from the surface to avoid causing damage to the brick or mortar.

Chemical Cleaning

Chemical cleaning relies on the use of specific chemicals and solutions to clean brick surfaces. These specially formulated products break down and remove stubborn deposits like oil and stains. Some common chemicals used in this process include:

  • Hydrochloric acid: Effective for cleaning mortar stains and mineral deposits.

  • Alkaline cleaners: Effective for cleaning grease and oil stains.


Soft-washing is a gentle method of brick cleaning that uses a combination of low-pressure water and specialised cleaning solutions. It’s an excellent choice for fragile or older brickwork that might be damaged by high-pressure washing or harsh chemicals. Soft-washing targets organic growth and dirt without causing abrasion to the brick surface.

This method typically involves pre-wetting the brick surface and applying the cleaning solution. The solution is then allowed to dwell for a short period to penetrate the brickwork and loosen the dirt and grime. Lastly, the brick is gently rinsed with low-pressure water to reveal a clean, fresh surface.
