Empire House is a multi-storey commercial building located on Empire Way in Wembley, London. Positioned within one of the capital’s most recognisable and active regeneration areas, the building forms part of Wembley’s wider commercial and mixed-use landscape.

‍

As Wembley has continued to evolve, buildings such as Empire House have played an important role in supporting the area’s transition from older commercial stock into modern, usable and better-presented spaces. For commercial buildings in high-profile locations, external appearance matters. A tired or heavily stained façade can reduce the perceived quality of the asset, while a carefully cleaned and restored exterior can help the building feel sharper, better maintained and more commercially relevant.

‍

Impact Restoration Ltd was appointed to carry out specialist external façade cleaning works as part of a refurbishment programme led by Detail Developments (London) Ltd. The project required a controlled cleaning approach that would restore the building’s appearance while protecting the existing façade materials.

The Building and Project Context

Empire House is located in Wembley, an area that has undergone significant change in recent years through commercial, residential and public realm development. Within this environment, older commercial buildings need to maintain a strong visual standard to remain attractive, functional and aligned with the surrounding area.

A Brent Council planning record for Empire House, Empire Way, Wembley, references external refurbishment of the existing building as part of a wider proposal, showing the role of façade improvement within the building’s continued development and use.

For projects of this nature, façade cleaning is not simply about improving kerb appeal. It helps restore the building’s external condition, remove years of environmental build-up and support the wider refurbishment objective. When carried out properly, it can improve presentation without damaging the surface beneath.

This was particularly important at Empire House, where the external façade required specialist treatment to remove staining and grime while preserving the integrity of the building fabric.

‍

The Challenge

Before works began, the façade had been affected by a heavy build-up of dirt, grime and environmental staining.

Like many commercial buildings in urban locations, Empire House had been exposed to traffic pollution, weathering, airborne contaminants and everyday environmental pressure over time. These factors had contributed to a visible deterioration in the external appearance of the building.

‍

The project presented several key challenges:

• Heavy build-up of dirt, grime and environmental staining
• Deterioration in the external appearance of the façade
• Requirement for specialist cleaning methods to avoid damage to building materials
• Access challenges requiring safe working at height solutions
• Need to complete the works as part of a wider refurbishment programme
• Requirement to achieve a professional finish with minimal disruption

‍

‍

The building’s height and scale meant that access planning was a critical part of the project. The façade needed to be cleaned safely and consistently across the external elevations, requiring suitable access equipment and careful site management.

The cleaning method also needed to be carefully selected. A basic high-pressure clean could have risked damaging the surface or producing an uneven finish. The aim was to remove contamination effectively while protecting the building materials and delivering a controlled restoration outcome.

The Solution

Impact Restoration delivered a specialist façade cleaning solution using vapour blasting techniques.

Vapour blasting is a controlled cleaning method that combines water with abrasive media to remove surface contaminants more carefully than dry blasting.
