Jet Washing – Professional Pressure Washing for Patios, Driveways & Properties

Jet washing is a high-pressure exterior cleaning method used to remove dirt, algae, moss, grime and surface staining from patios, driveways, paving and other suitable outdoor surfaces. Also known as pressure washing, it can restore neglected exterior areas and form part of routine residential or commercial property maintenance.

The right pressure, nozzle, cleaning method and surface assessment are important because excessive pressure can damage paving, pointing, timber and certain rendered or painted finishes.

What Is Jet Washing?

Jet washing uses pressurised water to loosen and remove accumulated surface contamination.

It is commonly used for:

• Patios
• Driveways
• Block paving
• Paths
• Concrete
• Decking
• Garden walls
• External steps
• Courtyards
• Commercial entrances

Professional contractors normally adjust their cleaning method according to the material rather than using maximum pressure on every surface.

Jet Washing vs Pressure Washing

The terms jet washing and pressure washing are commonly used interchangeably in the UK.

Both generally describe cleaning with pressurised water.

However, professional exterior cleaning can involve several approaches, including:

• Pressure washing
• Power washing
• Soft washing
• Steam cleaning
• Specialist chemical treatment

The correct method depends on what is being cleaned and the type of contamination present.

Professional Jet Washing

Professional jet washing can be useful where ordinary sweeping and household cleaning cannot adequately remove built-up grime.

A typical service may involve:

Inspection → Surface Preparation → Cleaning → Rinsing → Treatment Where Required → Re-Sanding or Sealing Where Appropriate

The scope should be agreed before work starts.

Driveway Jet Washing

Driveways can accumulate:

• Dirt
• Algae
• Moss
• Vehicle residue
• Organic staining
• Weeds between joints

Pressure washing can improve the appearance of suitable driveway surfaces.

However, the contractor should first establish whether the driveway is:

• Block paving
• Concrete
• Tarmac
• Resin-bound
• Natural stone

These materials require different cleaning approaches.

Block Paving Jet Washing

Block paving is a common candidate for pressure washing, but care is required around the joints.

High-pressure cleaning can remove some of the jointing sand between blocks.

As a result, professional block-paving cleaning may involve:

1. Pressure cleaning
2. Allowing the surface to dry
3. Replacing suitable jointing sand
4. Sealing where requested and appropriate

Re-sanding should be included in the quotation if required rather than assumed to be part of basic jet washing.

Patio Jet Washing

Patios frequently develop:

• Green algae
• Moss
• Dirt
• Organic deposits
• Weather staining

Pressure washing can restore suitable paving, particularly after winter.

Natural stone requires additional care because some materials can be damaged by aggressive pressure or unsuitable chemicals.

Concrete Pressure Washing

Concrete is generally durable, but that doesn't mean unlimited pressure should be used.

Older or deteriorated concrete may have:

• Cracks
• Weak surfaces
• Previous repairs
• Loose sections

These should be assessed before cleaning.

Jet Washing Natural Stone

Natural stone requires a more considered approach.

Examples include:

• Sandstone
• Limestone
• Granite
• Slate

The appropriate cleaning method depends on the stone and its condition.

Excessive pressure can potentially damage softer surfaces, while unsuitable chemicals can cause staining or deterioration.

Indian Sandstone Jet Washing

Indian sandstone patios are common across UK homes.

Jet washing may remove dirt and biological growth, but excessive pressure can damage the stone surface or pointing.

A contractor should consider:

• Stone condition
• Joint condition
• Existing sealant
• Type of staining
• Appropriate pressure

Avoid treating every sandstone patio as though it were ordinary concrete.

Decking Jet Washing

Timber decking can be pressure washed, but high pressure can damage the wood fibres.

Incorrect cleaning may leave timber:

• Rough
• Splintered
• Striped
• Unevenly coloured

Lower-pressure cleaning or another appropriate treatment may therefore be preferable.

Decking may also require treatment after it has dried.

Garden Wall Jet Washing

Garden and boundary walls can collect algae, moss and atmospheric dirt.

Before jet washing, check:

• Brick condition
• Mortar joints
• Render
• Paint
• Existing cracks

Older masonry and deteriorated pointing may not tolerate aggressive pressure washing.

Can You Jet Wash Brickwork?

Sometimes, but caution is important.

High-pressure water can damage:

• Weak mortar
• Weathered brick faces
• Historic masonry
• Painted surfaces

Older and heritage properties may require a gentler cleaning method.

Professional assessment is preferable before using powerful equipment on external brickwork.

Can You Jet Wash Render?

Not all render should be pressure washed.

High pressure can damage or penetrate:

• Cracked render
• Painted render
• Thin-coat systems
• Deteriorated finishes

Soft washing or lower-pressure cleaning may be more suitable for some rendered elevations.

Jet Washing Moss and Algae

Moss and algae commonly develop where exterior surfaces remain:

• Shaded
• Damp
• Poorly drained
• Surrounded by vegetation

Pressure washing can remove visible growth, but the underlying conditions may allow it to return.

Longer-term management may involve:

• Improving drainage
• Reducing persistent shade where practical
• Appropriate biocidal treatment
• Routine cleaning

Any cleaning product should be suitable for the surface and used according to its instructions.

Jet Washing Oil Stains

Oil stains on driveways can be difficult to remove completely.

The outcome depends on:

• Surface material
• Type of oil
• How long it has been present
• Surface porosity

A fresh stain may respond better than oil that has penetrated porous paving for months.

Ask the contractor whether stain treatment is included in the standard cleaning price.

Jet Washing Weeds

Pressure washing can remove surface weeds and growth between paving joints.

However, it does not necessarily prevent regrowth.

For block paving, cleaning can also remove jointing material, so re-sanding may be required afterwards.

Jet Washing Before Painting

Exterior surfaces sometimes need cleaning before painting.

Removing:

• Dirt
• Algae
• Loose contamination

can improve preparation.

However, the surface must be allowed to dry appropriately before coatings are applied.

Pressure washing should also not be used as a substitute for repairing:

• Cracks
• Failed render
• Loose paint
• Damaged masonry

Preparation requirements depend on the coating system being used.

Jet Washing Before Sealing

Driveways and patios may be sealed after cleaning.

The usual process c
