From Chemical, Abrasive and Steam Heritage Cleaning...

We provide a wide range of industrial cleaning solutions - from eco-chemical masonry cleaning, to abrasive grit blasting. 

The cleaning methods used will depend on the type of substrate and finish required. At WJ Structures we always use eco-friendly, biodegradable solutions in the interest of environmental conservation. Restoration is at the heart of what we do, and as approved contractors of Stone Health, our cleaning expertise and equipment allows us to offer all aspects of restorative cleaning.


Our restorative cleaning systems such as the DOFF Integra system by Stone Health offers a specialist cleaning method designed to have a gentle touch on the buildings substrate whilst still being powerful enough to remove all types of dirt & surface debris. It's intelligent design works by firing high temperature steam at the subject surface allowing the quick removal of all types of paint coatings and lichen growth. The DOFF systems low intensity/high impact nature makes it ideal for restorative stone cleaning, terracotta and other delicate building materials.


A secondary addition to our range of cleaning solutions is the TORC system. Another brainchild of Stone Health, this system offers gentle means of effective cleaning by creating a pressurised vortex combination of air, water and granulate matter to powerfully remove all types of debris from surfaces including carbon deposits. All whilst sustainably conserving water due to its low volume functionality.



Chemical cleaning is generally the most suitable approach for historic brickwork as it is able to accommodate variations in texture, condition and hardness, and it is undoubtedly the best method for the removal of paint.

Significant advance in chemical cleaners now mean that softer surfaces such as Sandstone/Portland stone can be cleaned using enzymes to digest the dirt, thus avoiding other cleaning systems which could damage the surfaces.

Abrasive Cleaning is the operation of forcibly propelling a stream of abrasive material against a surface under high or low pressure.

We use abrasive blasting to remove paint, lime-wash and carbon. This system can also be used to clean brickwork, steel railings or beams from internal or external walls. It is a popular procedure for exposing brickwork for internal feature walls.

We have invested in a state-of-the-art cleaning systems so that we are able to clean to a very high standard, in a gentle way, and causing minimum distress to the stone.The system can remove bacterial growth, lichen, moss and graffiti using low pressure and high temperature steam. The stone surface doesn’t get saturated with water and dries in minutes so the whole process is kind to stone with outstanding results.

We have a team of expert technicians who have vast experience cleaning buildings such as cathedrals, churches, castles, estates, public buildings and private properties.
