If you are asking how much should patio cleaning cost, this guide gives you a clear answer. Most UK patio cleaning prices depend on patio size, surface type, condition, moss, algae, stains, access, and whether you need sealing, soft washing, or re-sanding.
A clean patio can make your garden feel fresh, safe, and ready to enjoy again. However, prices can vary a lot. One company may offer a low-cost quick wash, while another provides a careful professional clean with treatment, protection, and aftercare.
At Chiltern Surface, we believe homeowners deserve clear advice before booking a service. Patio cleaning is not just about blasting water at paving slabs. The right method protects the surface, removes dirt properly, and helps your patio stay cleaner for longer.
What Patio Cleaning Actually Depends On
There is no single price for patio cleaning, because no two patios are the same job. What you pay reflects the area to be cleaned, the surface it is laid in, how much growth and staining has built up, and what the patio needs afterwards to stay clean.
A small, lightly soiled patio is a short visit. A large one carrying years of moss, algae, lichen and ingrained staining is a different piece of work entirely — and the difference is in the hours and the method, not a rate card.
Why Area Alone Does Not Decide the Price
Some companies quote purely by area. It is a simple number, but it ignores the things that actually drive the time on site: whether the surface is porous, how deep the staining has gone, whether the joints need re-sanding, and how easily the patio can be reached with equipment and water.
Two patios of identical size can be very different jobs. That is why we quote after seeing the surface rather than from a measurement alone.
What Affects Patio Cleaning Cost?
The answer to how much should patio cleaning cost depends on several key factors.
Main price factors include:
- Patio size
- Surface type
- Dirt level
- Moss and algae growth
- Black spot or lichen
- Oil stains or rust marks
- Access to water and drainage
- Furniture removal
- Re-sanding needs
- Sealing requirements
- Location and travel time
A simple clean is cheaper. A full restoration costs more because it takes more time, skill, and treatment.
Cost by Patio Surface Type
Different surfaces need different care.
Natural stone can be delicate. Porcelain can streak if not rinsed well. Block paving may need re-sanding. So, the cheapest method is not always the safest.
What Pressure Washing Involves
Pressure washing suits dirt, mud, grime, light algae, loose moss and surface marks. What it costs comes down to the area, the access, and how much preparation and rinsing the surface needs.
Pressure washing is useful for:
- Dirt
- Mud
- Grime
- Light algae
- Loose moss
- Surface marks
However, high pressure can damage joints, grout, pointing and soft stone. Professional patio cleaning is not just the machine time — it is the skill, the right equipment, the setup, controlled pressure and a proper rinse down.
Soft Washing Patio Cost
Soft washing uses cleaning solutions and lower pressure. It is useful for algae, moss, mould, mildew, and organic growth.
Soft washing may cost more than basic pressure washing because it includes treatment time.
Typical cost range:
Soft washing is often a better option when the patio needs a longer-lasting clean.
Sealing After Cleaning
Sealing helps protect patio slabs after cleaning. It may reduce staining, slow water absorption and make future cleaning easier. What it adds depends on the area and on the product the surface actually needs.
Sealing is useful for:
- Concrete
- Natural stone
- Sandstone
- Limestone
- Some block paving
Porcelain usually does not need sealing, but grout lines may still need care.
Re-Sanding Block Paving
If your patio is block paving, cleaning can remove jointing sand. Re-sanding helps stabilise the blocks, and what it adds depends on the area and the condition of the joints.
This is an important step rather than an optional extra. Without re-sanding, joints can become loose and weeds return faster.
Why Cheap Patio Cleaning Can Cost More Later
A very cheap quote may sound attractive, but it can lead to problems.
Low-cost cleaning may cause:
- Damaged slabs
- Blown-out joints
- Streaky pressure marks
- Uneven cleaning
- Poor moss removal
- Fast algae regrowth
- No aftercare advice
- Hidden extras later
Professional cleaning is not just about water pressure. It is about knowing what each surface needs.
DIY vs Professional Patio Cleaning Cost
DIY cleaning may seem cheaper at first.
DIY can work for light dirt. But for moss, algae, lichen, stains, natural stone, or large patios, professional cleaning is often better value.
Is Professional Patio Cleaning Worth It?

Benefits include:
- Better kerb appeal

About How Much Should Patio Cleaning CostConclusion
So what should patio cleaning cost? The honest answer is that it depends on the work your patio actually needs — its size, its surface, how much growth and staining has taken hold, how it is reached, and whether it needs re-sanding or sealing afterwards.
The right price depends on the work needed, not just the size of the patio. A careful professional clean can improve safety, restore appearance, protect the surface and help your outdoor space last longer.

Frequently asked questions
What decides the cost of patio cleaning?
Size, surface type, condition, access and any aftercare such as sealing or re-sanding. The condition of the patio usually matters more than its size.
Is pressure washing cheaper than a full clean?
Not necessarily. The right method depends on the surface — using pressure where a soft wash is needed risks damage that costs far more to put right.
Is patio cleaning charged by the hour or square metre?
Some companies charge hourly, while others charge per square metre or by the full job. A full quote is usually more accurate.
Why do patio cleaning prices vary so much?
Prices vary due to patio size, surface type, moss, algae, stains, access, drainage, sealing, and re-sanding needs.
Is sealing included?
Sealing is a separate step, and not every surface needs it. We will tell you at the site visit whether yours would benefit.
Is cheap patio cleaning a bad idea?
Not always, but very cheap cleaning may mean rushed work, poor equipment, no treatment, or risk of surface damage.
How often should I book professional patio cleaning?
Most patios benefit from professional cleaning once a year, especially after winter.
How do I get an accurate patio cleaning quote?
The best way is to book an assessment. Chiltern Surface can review the patio size, surface, condition, and treatment needs.
