The area is the starting point. The surface type and whether it needs re-sanding afterwards are what actually vary.
Power washing is quoted on area, surface type and how heavily soiled it is. Block paving costs more than a plain concrete slab area of the same size, because it needs re-sanding afterwards.
We do not publish fixed prices for this work, because the honest answer is that it varies more than a price list would suggest. What we can do is explain exactly what moves the number, so that when you call for a free quotation you already know what we will be asking about.
The basic measure. Larger areas usually cost less per square metre because set-up and equipment time is spread further — the same reason that applies to most outdoor work.
| Surface | Consideration |
|---|---|
| Concrete slabs / flags | Straightforward. The most economical to clean |
| Block paving | Needs re-sanding afterwards — this is an additional stage |
| Natural stone | Gentler pressure; softer stone needs care |
| Imprinted concrete | Care needed to avoid stripping the sealant |
| Decking | Low pressure, wider fan; easily damaged |
| Brick and render | Depends heavily on age and condition of the mortar |
| Tarmac | Generally should not be pressure washed |

Worth being clear about, because it manages expectations before rather than after.
It is quoted on area, surface type and how heavily soiled the surface is. Block paving costs more than plain slabs of the same size because it needs re-sanding afterwards.
Because washing removes the kiln-dried sand between the blocks, which has to be replaced or the paving works loose. It is an extra stage and it is not optional.
It should be, on block paving. It is the stage most often left out of a cheap quote, so ask directly when comparing prices.
Sometimes only partially. Oil that has soaked deep into porous concrete may lighten rather than disappear completely.
Generally not at high pressure — it can lift and damage the surface. Tarmac is better cleaned by gentler methods.
It helps considerably. Power washing uses a lot of water, and where there is no supply it has to be brought, which affects the job.
Every one to two years suits most surfaces. Shaded, north-facing and tree-covered areas green up faster and may need doing annually.
Not when the pressure is matched to the material. Older, softer stone and worn mortar need lower pressure, and some surfaces are better cleaned by other means.
