Proof, not promises
A finish that changes how the garden feels.
Most patios do not need replacing — they need restoration. A controlled wash lifts the dirt and a proper post-treatment kills the algae and black spot at the root, so the stone stays cleaner for longer.
- Removes algae, black spot, moss and years of ground-in dirt
- Safe for sandstone, limestone, porcelain and block paving
- Optional joint re-sanding and re-pointing available as priced add-ons
- Optional sealing to slow re-growth and protect the finish
Every stone, done properly
What is the right method for cleaning a patio?
Different stones need different pressure, different chemistry and a different pair of hands. Andrew has cleaned every surface below on patios across Oxfordshire and Buckinghamshire.
Limestone
Careful cleaning that lifts biological staining without etching or dulling the natural finish. Ideal for wet-look restoration.
Porcelain
Streak-free cleaning of modern porcelain paving using the right chemistry — no acid, no scarring, no residue.
Block & brick paving
Deep clean of the blocks and joints. Optional re-sanding or re-pointing available as a priced add-on to lock the blocks and keep weeds down.
How it works
How does patio cleaning work?
No rushed jobs, no zebra stripes, no gouged pointing. Every patio gets the same considered process — that is why the results hold up.
- 01
Survey
We look at the stone, drainage and joint condition so we choose the right pressure and chemistry.
- 02
Pre-treat
A specialist biocide is applied to kill algae and lift biological growth from within the stone.
- 03
Clean
Rotary heads at controlled pressure give an even, streak-free finish — no zebra stripes, no gouging.
- 04
Finish
Edges rinsed, area left tidy. Re-sanding and re-pointing are available as priced add-ons if the joints need it — quoted separately so you only pay for what you want.
Black spot, algae & lichen
What is black spot, and why does it come back?
Black spot is a lichen that roots into the pores of the stone, not a stain sitting on top of it. That is why jet washing alone never keeps it away. Every patio we clean gets a specialist biocide post-treatment that kills the organism at the root and keeps working for weeks after we leave.
Black spot lichen
Those stubborn dark dots that will not budge with a jet wash. Black spot is a lichen that roots into the pores of the stone, so pressure alone only shaves the top off it. It needs a dwell-time biocide to kill the organism at the root — after which it fades over the following weeks rather than disappearing in an afternoon.
Algae & green film
The slippery green layer on north-facing and shaded patios. Algae feeds on moisture and shade, which is why it returns fastest under trees and beside fences. It washes off readily, but without a post-treatment it is back within a season.
Moss & weeds in joints
Moss holds water against the stone and lifts jointing over time. We clear the joints during the wash, and where the sand or pointing has gone we quote re-sanding or re-pointing separately so you only pay for what is actually needed.
Why biocide, not bleach
Household bleach whitens staining for a few weeks and then it returns, because nothing has been killed. A professional biocide is applied after cleaning, left to dwell, and continues working long after we leave. That post-treatment is included in every patio price on this page.

Who we clean patios for
Different homes, different priorities.
Most patios need the same care and a different plan. Here is how we usually approach each kind of job across Thame and the surrounding villages.
Period & village homes
Yorkstone, flagstone and older sandstone that cannot take blasting. Low pressure, correct chemistry, pointing left intact — the finish looks its age in the right way.
Modern family homes
Porcelain, Indian sandstone and block paving around the seating area. A single-day clean and post-treatment so the garden is usable again by the weekend.
Selling, letting or hosting
A clean patio changes the first photograph and the first impression. Book ahead of a viewing, a listing shoot, a wedding or a summer party and we work to your date.
Larger properties & grounds
Terraces, steps, paths and pool surrounds cleaned as one project. Quoted as a whole, delivered in a planned sequence, with photographs at each stage.

Local stone and local conditions matter. Shaded, north-facing gardens backing onto the Chiltern treeline hold moisture and grow black spot fastest, while older village flagstone needs far gentler handling than modern porcelain. We clean all of it every week, within half an hour of home.

FAQs
Patio cleaning questions, answered.
Will pressure washing damage my patio?+
Not when it is done properly. We match pressure and chemistry to the stone — sandstone, limestone, porcelain and block paving all need different settings. We never blast slabs or gouge joints.
What is black spot and why does it keep coming back?+
Black spot is a lichen that roots into the pores of the stone rather than sitting on top of it. Pressure washing alone removes only the surface, so it reappears within months. Killing it needs a dwell-time biocide applied after the clean — it then fades over the following weeks and stays away far longer.
Will the cleaning harm my plants, lawn or pets?+
No. Beds and borders are wetted down before we start and rinsed afterwards, and the biocide we use is applied at a controlled dilution to hard surfaces only. Once the patio is dry, it is safe for children and pets.
Do you re-sand block paving joints?+
Yes — re-sanding and re-pointing are available as priced add-ons. Fresh kiln-dried sand is brushed and vibrated into the joints to lock the blocks and keep weeds down. It is quoted separately so you only pay for what you actually want done.
Can you seal the patio afterwards?+
Yes — sealing is an optional add-on. It slows re-growth of algae, deepens the colour and makes the next clean easier. We only seal once the stone is fully dry, usually on a return visit.
How long does a patio take?+
Most domestic patios are cleaned in a single day, including post-treatment. Larger patios or combined patio + driveway jobs can run into a second day.
How soon can you come out?+
We usually reply with a fixed price within one working day of receiving your photos, and most patios are booked in within one to three weeks depending on the season. Spring and early summer are the busiest, so book ahead if you have a date in mind.
How often should I have my patio cleaned?+
Most patios in Oxfordshire benefit from a professional clean every 18–24 months. North-facing patios under trees may need it more often; sunny south-facing patios can go longer.
Do I need to be home?+
No. As long as we have access to an outside tap and the patio itself, you do not need to be there. We will send before and after photos when we finish.
