Pressure Washing Driveways & Patios: What It Removes and When Cleaning Is Enough
Over time, driveways and patios naturally lose their original appearance due to dirt, moisture, and everyday use. Moss growth, dark staining, and surface discolouration often lead homeowners to believe their driveway or patio needs replacing — but in many cases, professional pressure washing can restore the surface without the cost or disruption of replacement.
For Kent homeowners, understanding what pressure washing can remove — and knowing when cleaning is enough — can help you make a more informed decision.
What Can Pressure Washing Remove from Driveways and Patios?
Professional pressure washing is designed to remove surface contaminants safely and effectively. Kent’s damp climate makes outdoor surfaces particularly prone to organic growth and staining.
Moss
Moss is one of the most common problems on driveways and patios in Kent. It thrives in shaded or damp areas and can quickly spread across paving. Pressure washing removes moss from the surface and joints, improving appearance and reducing slip hazards.
Algae
Algae causes green or dark staining and can make surfaces dangerously slippery when wet. Pressure washing removes algae effectively, restoring the original colour of your driveway or patio and improving safety.
Lichen
Lichen appears as stubborn white, grey, or yellow patches that can bond tightly to paving. Left untreated, it can cause surface deterioration. Professional pressure washing removes lichen safely without damaging the underlying material.
Oil Stains
Oil stains from parked vehicles are common on driveways. While some stains may look permanent, professional pressure washing combined with specialist treatments can significantly reduce or remove oil marks, particularly when treated early.
Tyre Marks
Tyre marks and traffic staining build up over time, especially on driveways with regular use. Pressure washing removes these marks, instantly refreshing the overall appearance of the surface.
Weeds
Weeds often grow between joints rather than through the surface itself. Pressure washing removes weeds and their roots from joints, helping slow regrowth when followed by proper re-sanding or jointing.
When Pressure Washing Is Enough
Pressure washing is usually sufficient when the surface itself is still structurally sound.
Cleaning is often the best option if:
- The driveway or patio is level and stable
- There are no major cracks or sinking areas
- Discolouration is caused by dirt or organic growth
- Weeds are limited to joints and gaps
In these cases, pressure washing can dramatically improve appearance and extend the lifespan of your driveway or patio.
When Replacement May Be the Better Option
There are situations where cleaning alone won’t resolve the issue.
Replacement may be necessary if:
- The surface has deep cracks or potholes
- Blocks are loose or continually sinking
- Drainage problems are caused by sub-base failure
- The surface has reached the end of its usable life
A professional inspection can help determine whether pressure washing or replacement is the most cost-effective solution.
Why Professional Pressure Washing Matters
Using incorrect pressure or techniques can damage paving, remove jointing sand, or mark certain surfaces. Professional pressure washing ensures:
- The correct pressure for each surface type
- Safe removal of contaminants without damage
- Longer-lasting results when combined with re-sanding or sealing
