Experience & Expertise

Over the years we have gained a lot of experience from a variety of pressure washing jobs, cleaning all kinds of exterior surfaces, for our residential and commercial customers throughout Northumberland. 

Our pressure washer uses a completely controllable pressure so we can adjust to suit more fragile surfaces. 

We use Biocide treatment on all our jobs to ensure your surfaces remain in the best condition possible and helps prevent moss or any other biological growth from coming back for a longer time than if you were to only pressure wash. Which could actually cause moss come back worse than before.

We collect all debris and take with us for disposal. Our quality of work speaks for itself, with many customers coming back to us for further work year after year.

Purified Water

Otherwise known as pure water window cleaning and deionised water.


Ordinary tap water is full of minerals. Some of these minerals remain on the window when the water evaporates. Leaving behind stains and spotting.

This is why the water we use is purified using filters and resins, making use of natural processes like reverse osmosis and deionisation to remove all the impurities to prevent this. And, because this is a natural process with no harsh chemicals, we have greatly reduced our eco-footprint.

We can use this water to clean glass, window frames, fascias & soffits, conservatory roofs more effectively. Purified water dries crystal clear so there is no need to squeegee the water from the window. 

We test our water using a TDS meter to ensure the water is reading between 0-7 ppm (parts per million) for it to be able to dry clear on your windows.
