GNT Services · Yorkshire & Lancashire
Specialist knowledge, professional equipment and a genuine commitment to achieving the best possible result for every property.
From restoring stained render on a family home to cleaning the exterior of a large commercial building, we take pride in doing the job properly.
Who we are
GNT Services is a Yorkshire-based exterior cleaning company providing professional cleaning and restoration services for residential, commercial and public-sector properties.
Operating from Oakworth, near Keighley, we work across Yorkshire and Lancashire, helping property owners, businesses and organisations restore and maintain the appearance of their buildings and outdoor spaces.
Our work covers everything from specialist K Rend cleaning and roof cleaning to driveway restoration, commercial cladding cleaning and larger exterior maintenance projects.
What connects these services is our approach. We believe achieving a good result starts with understanding the surface, the type of contamination and the most appropriate way to treat it.
That means assessing the job properly, explaining what can realistically be achieved and selecting equipment and cleaning methods suited to the property.
Whether we're working on someone's home or a large commercial site, our aim is the same: professional workmanship, reliable service and results we can take pride in.
The GNT approach
There's no single cleaning process that's right for every property. Different materials, finishes and types of contamination require different methods.
From silicone render and natural stone to roof tiles and commercial cladding, we assess the surface and its condition before deciding how to clean it.
This helps us avoid unsuitable methods and identify existing defects that might affect the work.
Our services incorporate specialist soft washing, controlled pressure washing and other professional cleaning techniques where appropriate.
The method is selected for the surface rather than simply relying on maximum pressure.
We aim to provide clear advice, sensible quotations, careful preparation and work carried out with attention to detail.
We also explain when staining, damage or an underlying building defect may require something other than cleaning.
Specialist experience
Some of our most demanding work involves surfaces where the wrong cleaning method could cause permanent damage.
Modern K Rend, monocouche and silicone render systems can develop algae and discolouration, but aggressive pressure washing may damage delicate finishes.
Likewise, different types of natural stone, commercial cladding, roofs and external paving require their own cleaning considerations.
Our experience across a wide range of exterior cleaning projects helps us assess which methods are appropriate and what results are realistically achievable.
We use professional equipment and cleaning solutions and consider the material, access requirements and surrounding environment before carrying out the work.

Alongside residential cleaning, GNT Services works with commercial customers requiring professional exterior cleaning across larger or more complex sites.
These projects can involve additional requirements around equipment, access, safety, working hours and coordination with site managers.
We understand that exterior cleaning on an occupied commercial site needs to be planned around the building, its users and the practical demands of the work.
Whether the project involves commercial render, cladding, external paving or a wider maintenance requirement, we begin by discussing the scope and site conditions.
Where relevant, risk assessments, method statements, access requirements and other documentation can be discussed during the quotation and planning process.
