Shade, damp and the Cobham patio
Many homes here back onto woodland or have mature oak, beech, birch and pine in the garden, especially on the larger plots around Fairmile, Oxshott Road and Leigh Hill. Leaves drop onto the patio and sit there, shade stops it drying out, and before long the stone has gone green, slippery and dull. Pine needles in particular sit in joints and hold moisture.
Down by the River Mole, towards Church Cobham and Downside, damp air does the same job. Terraces that face north or sit below the level of the lawn rarely dry properly between October and April. That is when algae spreads and lichen and black spot settle into the stone.
It is also worth looking at your patio after a wet winter. If it has gone slippery, that is a safety issue as much as a looks one, especially for children, older relatives and anyone carrying trays out to the garden. A quick steam clean in spring sets the terrace up for the summer, when gardens get the most use.

The stone we see in Cobham gardens
Indian sandstone is the most common patio stone we clean here. It looks great when new, but it is porous, so algae and dirt soak into it and black spot lichen sets into the surface. Porcelain is popular on newer homes and recent garden makeovers. It is not porous, but it still grows a green film and picks up marks, and it can be very slippery when damp.
On older and more traditional houses we also see York stone, which is softer and needs careful handling, plus concrete and reconstituted slabs on more modest patios and paths. Each one reacts differently to cleaning, which is why we do not use one setting for everything.

What steam does that a jet washer cannot
A domestic jet washer can make a patio look cleaner for a few weeks, but it often blows out the jointing, etches the surface of sandstone, leaves stripes and drives water and spores into the stone so it comes back faster. It also does very little to black spot lichen, which is anchored into the stone.
Our low-pressure steam heats and softens growth right down to the root and rinses it off without scouring the stone. It lifts algae, lichen and black spot, and because we do not rely on harsh chemicals there is no risk to the borders, lawn, pond or pool next to your terrace. It is also gentler on the joints, which matters on older York stone and on sandstone laid with traditional mortar.

Patio cleaning as part of a bigger job
In Cobham we rarely clean a patio on its own. One customer had the full works: roof steam clean and treatment, patio steam clean, driveway clean and re-sand, gutters cleared, fascias and soffits cleaned and the windows done. Another had a full exterior with the roof, stonework restoration, patio and driveway all brought back together.
If you are planning more than one job, we work from the top down. The roof and gutters come first, then stonework and walls, and the patio and driveway last, so everything we wash off higher up is cleaned away at the end rather than landing on stone we have just finished.
Once your patio is clean, a few simple habits help it stay that way: sweep leaves and pine needles off regularly in autumn, keep gutters clear so they do not overflow onto the terrace, and trim back anything that casts heavy shade if you can. Sandstone and porcelain in shadier gardens will always need some attention, but starting from properly clean stone makes a big difference.

Cobham terraces, pools and garden paths
Patios on the larger homes are rarely just a square of paving by the back door. We often clean wide terraces that wrap around the house, steps down to the lawn, stone paths through the garden and surrounds to swimming pools. Each has its own mix of shade and sun, and the paths that run under trees are usually the worst.
Because steam does not need harsh chemicals, it is well suited to paving next to pools, ponds and planted borders. We work methodically across the whole area so the finish is even, and we pay attention to the edges and corners where moss and algae tend to hide.
What We See on Cobham Properties

Patio Cleaning Cobham FAQs
Answers to common questions about our exterior cleaning services. Can't see yours? Give us a call — we're always happy to help.
Can you remove black spot from my sandstone patio?
Yes. Our steam cleaning lifts algae, lichen and black spot from Indian sandstone. Very old, deeply set marks can sometimes leave a faint shadow, and we will tell you honestly what to expect when we quote.
Is steam safe on porcelain?
Yes. Porcelain is not porous, so steam cleans the surface film off quickly without any risk of etching or staining.
Will cleaning damage my joints?
Low-pressure steam is far kinder to joints than a jet washer. If any jointing is already loose or missing, we will point it out.
Do you use chemicals near the garden?
No harsh chemicals are needed. Steam does the work, which is much safer for lawns, borders, ponds and pools beside your patio.
How long does a patio clean take?
Most patios are done in a day. Very large terraces, or patio cleaning combined with roof, driveway or stonework cleaning, may take longer, and we will give you a clear idea when we quote.
Can you clean the patio and driveway together?
Yes, and many Cobham customers do. We usually finish with the patio and driveway so that everything from higher jobs is cleared away last.
