Exterior Building Cleaning
First impressions count. The exterior of your premises is the first thing people see, so why wait until its too late for building cleaning and repair?

Buildings are at the forefront of damage including natural elements and wear and tear.

Traditional cleaning methods such as high-pressure washing or sand blasting can damage building facades and weaken their structure. APT offers unique building cleaning services that uses sympathetic cleaning components that will not harm substrate materials.

Our Work In Action - Building Cleaning Services

Our experienced teams have assisted numerous organizations and individuals nationwide with building cleaning. We provide tailored quotations to meet your specific needs.


We are proud to be the preferred supplier for CADW, English Heritage, Historic England, and Historic Scotland. Our collaboration extends to working closely with conservation architects and surveyors on heritage cleaning and restoration projects across the nation.

Here’s how we helped Blaenau Gwent Council with their building clean:

“We employed the services of APT to renovate a Grade 2 Listed Building. Under the directive of Cadw we were not allowed to use any wet process or chemicals within the interior of the building. APT used Soda Blasting on sandstone, brick, ceramic glazed tiles, metal work, paintwork on ceilings, coving, woodwork and ornate fixtures. 

It was a great achievement to have one system for all the surfaces that needed cleaning and restoring and one that also ticked all the boxes of the environmental and conservation officers. The process saved us both time & money in being able to have just one company on site. We are very grateful to APT for their hard work on this project.”

Why use Building Cleaning Services?

Neglecting to address exterior maintenance for financial reasons can result in more significant long-term expenses. Opting for quick fixes rather than proper solutions can further inflate costs.

Accumulation of dirt particles, algae, lichen, and bird droppings on building facades accelerates wear and tear, negatively impacts aesthetics, and harms the substrate material.

At APT, we bring over three decades of expertise in both interior and exterior building cleaning services. We rely on proven cleaning methods and utilize specialized, effective cleaning products.

Our adept team ensures the provision of precise solutions for cleaning and restoring your surfaces without causing substrate damage.

We prioritise your timeframe, constraints, and budget. A site survey enables us to assess your business needs, allowing us to create a structured plan that minimises downtime while enhancing cleanliness.

Brick & Stone Cleaning using Soda Blast Cleaning at River Island in Leeds


APT have been providing building cleaning services for three decades, supporting organisations throughout the UK with their building cleaning. Our specialist cleaning techniques founded on years of experience will provide dramatic results, without causing damage to the surface. As one of the UK’s trusted building cleaning companies, we clean a wide variety of facades, including:

  • Brick
  • Cladding
  • Granite
  • Limestone
  • Iron
  • Marble
  • Render & K Render
  • Stainless Steel
  • Stone
  • Wood

In short – it’s tough to say what a general clean includes. The reason is because we provide a no-obligation quote for all clients based on their needs. We’re in the business of providing cost-effective solutions, meaning that we will give you a quote based on we see. Every building is different and each surface needs to be cleaned in a specific manner which is why we do not just provide a “general clean”. 

Our teams are specialist and will assess your requirements and guide you as to what needs cleaning. We will put a plan in place to tackle your cleaning needs in a time conscious manner. 

All of our building cleaning jobs are different because the requirements of all businesses differ. Our process for pricing cleaning jobs is as follows:

  • Enquire through our website or call us on 0800 0723 773.
  • Our expert team will call you to discuss your project in more detail and arrange a site survey. 
  • One of our accredited surveyors will come to site to assess the job, allowing them to gain a better understanding of your business. 
  • We will send you a detailed quote based on your expectations and desires for cleaning
  • When organising a day to begin the works, we will work around you as our teams can work 24/7, nationwide, fitting around your business requirements to minimise downtime. 
Cleaning requirements depend on several factors; how often is the office used? What is the capacity for the use of the office? How many people are in the office on a daily/weekly/monthly basis? Call our expert team on 0800 0723 773 to determine how often your office should be cleaned. We will ask a number of specific questions and often request photographs before a site visit to asses how often you should receive office deep cleaning services.

Using your own staff and high-pressure jet washers to clean your building’s exterior facade is not cost-effective. Untrained staff can cause more harm to the substrate than good. Blasting the contamination off can worsen the building’s condition, and high-pressure washing can weaken surfaces and leave the facade vulnerable to environmental damage. It’s crucial to recognize the speed at which a building exterior can deteriorate.

Additionally, researching, buying chemicals, and renting equipment to access higher parts of the building can be challenging. Health and safety practices for exterior building cleaning are also essential. Hiring a professional commercial exterior building cleaning company can save time, money, and hassle. They have the experience and expertise to perform the job effectively, ensuring the building is safe and clean.
