​​​​​​​​​​​​What is involved in the cleaning process? ​ Your surfaces will be cleaned using high pressure water, delivered by a commercial specification Honda  petrol driven pressure washer. Surfaces such as walls are cleaned with a lance and flat surfaces are cleaned with a rotary cleaner.  This equipment will complete the job significantly faster and far more effectively than a DiY machine – saving you time and money.​ 

Can any home or business premises benefit from pressure washing? Yes. All we need to do is make sure that you have a suitable water supply to use i.e an outside tap and suitable access to the area to be cleaned. Unfortunately we are unable to undertake any jobs where there is no access to an external tap. Also we cannot carry out work where there is no external access to the area being cleaned. For example - we can't bring the equipment or high pressure hoses through a property to reach the back garden. 

What do I need to do to prepare? Make sure that for the duration of the clean all vehicles are removed from the driveway and all plant pots and garden furniture etc. are removed from the patio. (We’ll be happy to help you with this if required). You will also need to make sure that children and pets are kept away from the areas being cleaned while the work is taking place. 

Will I need to be at home when the cleaning takes place? No – there is no need to be in, providing that we have access to the water supply for the duration of the work. We wont need any access to your property. We generally arrive at 8am, set up the equipment and aim to be cleaning by 9am.


Are any chemicals used in the cleaning process?  The cleaning process generally uses just high pressure water. The only exceptions to this are if a de-greaser needs to be used on driveways oils-stains for example. We also use diluted bleach to help the cleaning process where necessary. We will discuss the use of chemicals with you first before using any.

Can all stains be removed?  The appearance of most stains will be significantly improved although it is impossible to guarantee they'll be completely removed. (Oil stains are especially difficult to remove completely for example). Similarly, we cannot guarantee to completely remove all algea and lichen. Black spot Lichen is VERY difficult to remove completely, although you will notice a significant improvement overall.

We have a water meter. How much will the water costWelsh Water currently charges £1.35 per cubic metre of water (source:, September 2015). The pressure washer uses approximately 0.9 cublic metres per hour, so every full hour of cleaning will use £1.21 of water.

Why are there no prices quoted on your website? We generally charge per 1/2 or full day, or mulitples thereof, and the price may also vary according to the size of the area to be cleaned, the type of surface it is and the condition it is in. We have a written price list and will be happy to show you that when we visit to give you a quotation. Our prices are very competitive and consistent from customer to customer.

My drive is covered in weeds. Will they come back?This is a very common question...Block paved driveways are very low maintenance, but not NO maintenance - so the answer is yes, weeds will come back. There may be root systems under the paving that cannot be removed by cleaning alone and weeds/seeds are also airborne, dropped by birds and from trees and plants - so you need to carry out routine maintenance by weed killing and sweeping. Add it to your gardening routine, just like cutting the grass or de-weeding flower beds.
