Washed surface

Pressure washing: a deep clean for your surfaces

Pressure washing is more than a cosmetic clean. It is the upkeep that extends the life of your pavers, removes moss and weeds, and prepares the surface for re-sanding where that is needed.

Pressure washing a paver driveway: a sharp line separates the grimy surface from the section already cleaned.
The demarcation line shows what the surface had lost under the build-up.

What you are seeing

Are your pavers discoloured? Is moss growing between them? Are there stains that will not come off? Does the surface just look old and dull?

What causes it

Discolouration and moss come from dirt, pollen and moisture building up season after season.

Freeze-thaw and damp create good conditions for moss, particularly in shaded areas and anywhere water lingers after rain.

What we do

We clean thoroughly with professional equipment and remove the moss and weeds.

Where it is needed we apply a protective treatment and re-sand the joints - because a wash that empties the joints without refilling them leaves the surface more exposed than it was.

What the work can include

The work varies with the condition of what is already there.

  • Assessing the surface type and the right pressure for it
  • Pressure washing the surface
  • Removing moss and weeds from the joints
  • Moss treatment where needed
  • Re-sanding the joints with polymeric sand
  • Rinsing and clearing the perimeter

Suitable surfaces

  • Paver driveways and parking areas
  • Patios and terraces
  • Walkways
  • Walls and coping
  • Pool surrounds

A fan tip held at the right distance - enough to lift the grime, not enough to cut the joint.

How it goes

  1. 01

    Assessment

    We look at the surface, the material and how much build-up there is.

  2. 02

    Washing

    We clean at the pressure that the surface can take.

  3. 03

    Treatment

    We apply a moss treatment where it is needed.

  4. 04

    Re-sanding

    We put polymeric sand back in the joints where that is needed.

  5. 05

    Check

    We check the result and clear the site.

What affects the price

The cost of a pressure wash depends on several things:

  • The area to be cleaned
  • How much dirt and moss there is
  • The type of surface
  • Joint re-sanding, where it is needed
  • Access to water and to the site

It is the most straightforward of the six services to price: in many cases a photo and the dimensions are enough for a quote. The assessment is still free.

Service areas

After a winter of salt and grit, most paver surfaces in the region come out of spring dull with their joints emptied. It is the time of year when washing and re-sanding make the most difference.
