If your driveway, patio, paths or exterior surfaces are covered in dirt, moss, algae or stains, pressure washing can make a dramatic difference to the appearance of your property.
But one of the first questions homeowners ask is:
How much does pressure washing cost in London?
The answer depends on several factors, including the size of the area, the type of surface, the level of dirt and whether additional treatments such as weed removal, re-sanding or sealing are required.
As a general 2026 guide, pressure washing services in London average around £264, with typical prices ranging from approximately £192 to £367. Driveway and patio cleaning can cost more, with an average of around £357 and a typical range of £272–£479.
In this guide, we’ll explain what you can expect to pay, what affects the price and how to get the best value from a professional pressure washing service.

How Much Does Pressure Washing Cost in London?
The cost of pressure washing varies depending on what needs to be cleaned.
As a useful starting point:
| Pressure Washing Service | Typical London Price |
|---|---|
| General pressure washing | £192–£367 |
| Average pressure washing job | Around £264 |
| Driveway & patio cleaning | £272–£479 |
| Average driveway/patio cleaning | Around £357 |
| Decking cleaning | £140–£236 |
| Weed & moss removal | £74–£153 |
These figures should be treated as guide prices rather than fixed quotes. The condition and size of the property can make a significant difference to the final cost.
For example, a small patio with light dirt may be relatively inexpensive to clean, while a large block-paved driveway covered with moss and weeds may require considerably more time and additional treatments.
What Factors Affect Pressure Washing Prices in London?
There isn’t a single fixed price for pressure washing because every property is different.
Here are the main factors that can affect your quote.
1. Size of the Area
The larger the area, the more time, water, equipment and labour are required.
A small front path will normally cost much less than a large driveway or patio.
For example:
- Small driveway → lower overall cost
- Medium driveway → moderate cost
- Large driveway → higher cost
- Multiple outdoor areas → higher overall quotation
Some companies may also have a minimum call-out charge, particularly for smaller jobs.
2. Type of Surface
Different materials require different cleaning techniques.
Common surfaces include:
- Concrete
- Block paving
- Natural stone
- Indian sandstone
- Porcelain paving
- Tarmac
- Resin-bound surfaces
- Timber decking
Pressure that is suitable for concrete may not be appropriate for more delicate materials.
A professional cleaner should therefore assess the surface before deciding on the cleaning method.
3. Level of Dirt and Staining
A lightly dirty patio is much easier to clean than a surface that has been neglected for several years.
Heavy contamination can include:
- Moss
- Algae
- Lichen
- Weeds
- Oil stains
- Black spots
- Mud
- General grime
The more severe the contamination, the more preparation and cleaning time may be required.
4. Accessibility
Access can also affect the price.
For example, a driveway directly next to the road may be straightforward to access, while a rear patio with limited access through the property may take longer to reach and clean.
Limited water access, drainage problems or difficult parking can also affect the job.
Driveway Pressure Washing Cost in London
Driveway cleaning is one of the most common reasons homeowners hire a pressure washing company.
According to 2026 UK cost data, driveway cleaning generally ranges from around £250 to £400, with a medium-sized driveway averaging approximately £350. London prices can be higher than other parts of the UK.
The price can increase if your driveway requires:
- Moss removal
- Weed removal
- Oil stain treatment
- Re-sanding
- Sealing
- Biocide treatment
For block paving, re-sanding may be particularly useful after deep cleaning because pressure washing can remove sand from the joints.

Patio Pressure Washing Cost in London
Patio cleaning prices depend heavily on the size and material of the patio.
As a 2026 UK guide, patio cleaning commonly costs around £3–£4.50 per m², although prices vary according to the material and condition.
For example:
| Patio Type | Typical Cleaning Cost per m² |
|---|---|
| Patio slabs | £2–£4.50 |
| Block paving | £2.50–£5.25 |
| Concrete | £2–£4.50 |
| Tarmac | £2–£4.50 |
| Timber decking | £3–£6 |
Additional sealing can increase the total price.
A professional patio cleaning service can help remove:
- Green algae
- Moss
- Black spots
- Dirt
- Weeds
- Organic stains
Does Pressure Washing Include Moss and Weed Removal?
Not always.
Some companies include basic moss and weed removal in their standard cleaning service, while others charge separately.
If your driveway or patio has significant moss or weed growth, ask whether the quotation includes:
- Weed removal
- Moss treatment
- Algae treatment
- Fungicidal or biocide treatment
- Re-sanding
- Sealing
This prevents unexpected costs after the work has started.
How Much Does Driveway Sealing Cost?
Sealing is an optional service that can be carried out after cleaning.
According to current UK cost guidance, driveway sealing can cost approximately £5–£17 per m², with an average of around £8 per m².
Sealing may help protect suitable surfaces against:
- Water penetration
- Staining
- Dirt
- Weed growth
- Weathering
However, the correct sealant depends on the surface material, so it should not automatically be applied to every driveway.
Is Pressure Washing Worth the Money?
For many homeowners, professional pressure washing can be worthwhile because it can restore the appearance of outdoor surfaces without the time and effort involved in doing the job yourself.
Benefits include:
Improved kerb appeal
A clean driveway or patio can make the entire property look better.
Time saving
Professional equipment can clean large areas much faster than manual scrubbing.
Removal of stubborn contamination
Professional equipment and appropriate treatments can tackle moss, algae and embedded dirt.
Safer cleaning
Using excessive pressure on the wrong surface can cause damage. Professionals can select an appropriate method for the material.
Convenience
You don’t have to purchase, transport, operate or maintain a pressure washer yourself.
DIY Pressure Washing vs Professional Cleaning
| DIY Pressure Washing | Professional Cleaning |
|---|---|
| Lower equipment cost if you already own a machine | Higher upfront cost |
| Requires your own time | Saves time |
| Risk of using incorrect pressure | Correct pressure and technique |
| May not remove heavy contamination | Professional equipment and treatments |
| You handle clean-up | Service normally includes clean-up |
| Limited experience | Experienced operator |
DIY can work for simple cleaning jobs, but surfaces such as natural stone, render, delicate paving and certain roof materials require extra care.
Can Pressure Washing Damage Your Property?
Yes, if it is carried out incorrectly.
Using excessive pressure or the wrong nozzle can potentially damage certain surfaces.
Potential problems include:
- Damaged paving
- Surface erosion
- Displaced jointing sand
- Damage to delicate materials
- Water entering vulnerable areas
- Damage to paint or render
This is why professional cleaners should assess the material and condition of the surface before choosing the cleaning method.
For some surfaces, soft washing or lower-pressure cleaning may be more appropriate than conventional pressure washing.
How Long Does Pressure Washing Take?
The time required depends on the size and condition of the area.
A small patio may take only a few hours, while a large driveway with heavy moss, weeds and staining can take considerably longer.
For example, current UK guidance estimates around 4–5 hours for a small driveway, 6–7 hours for a medium driveway and 7–8 hours for a large driveway, although actual times vary by property.
Additional treatments such as sealing or re-sanding will increase the overall time.
How Often Should You Pressure Wash Your Driveway or Patio?
There is no universal schedule.
For many properties, professional cleaning every 1–2 years can be a useful starting point, but the ideal frequency depends on:
- Local weather
- Shade
- Moisture
- Tree coverage
- Surface material
- Amount of foot traffic
- Moss and algae growth
Homes surrounded by trees or exposed to persistent moisture may need cleaning more frequently.
When Is the Best Time to Pressure Wash in London?
Spring and summer are often convenient times for exterior cleaning because surfaces can dry more quickly.
However, the condition of the property is more important than following a strict seasonal schedule.
If your driveway or patio has become:
- Slippery
- Green
- Blackened
- Covered in moss
- Difficult to maintain
it may be time for professional cleaning.
Important: water-use restrictions can affect outdoor cleaning in some parts of England. In July 2026, Thames Water introduced restrictions that included pressure washing outdoor areas for domestic users, while rules and exemptions vary by water company and circumstance. Always check the current rules before carrying out DIY pressure washing.
What Should Be Included in a Pressure Washing Quote?
Before booking a company, ask exactly what is included.
A good quotation should clarify:
Cleaning
- Pressure washing
- Surface preparation
- Rinsing
- Final clean-up
Treatments
- Moss removal
- Weed treatment
- Algae treatment
- Stain removal
Additional services
- Re-sanding
- Sealing
- Protective treatment
Also check whether the price includes VAT, equipment, labour and any minimum call-out charge.
How to Choose a Pressure Washing Company in London
Price should not be the only factor when choosing a cleaning company.
Look for a company that:
- Has experience with your type of surface
- Uses appropriate professional equipment
- Provides clear quotations
- Has public liability insurance
- Can show before-and-after examples
- Has genuine customer reviews
- Explains the cleaning method before starting
- Does not automatically use maximum pressure on every surface
A very cheap quotation may not always provide the best value if important treatments or preparation are excluded.
