Deep Patio Cleaning
Shade, damp and fallen leaves turn even good stone green over a few seasons, and the joints fill with weeds and black spots. Patio cleaning lifts that growth and grime so the slabs show their real colour again, and the surface is far less slippery when it rains.
The method depends on the stone. Porcelain and granite take a firm pressure wash, while softer sandstone and limestone need a gentler approach and a suitable cleaning solution so the face is not scoured. Black spot lichen usually needs a dedicated treatment, as pressure alone rarely shifts it.
Patio cleaning is available across Stevenage, Hitchin, Hatfield, Harpenden and the rest of Hertfordshire. It suits a patio you are happy with that simply looks tired, and it is worth doing before deciding whether any slabs really need relaying.
What a Patio Clean Includes
A thorough clean does more than rinse the surface. Depending on the stone and its condition, a typical patio clean includes the following work, agreed with you beforehand.
- Clearing furniture, pots and loose debris from the area
- Scraping weeds and moss out of the joints
- Pressure washing at a setting that suits the stone
- Treating algae and black spot lichen on the surface
- Spot treatment for rust, oil and food stains
- Re-pointing or re-sanding joints left open after washing
- Optional sealer on stone that suits one
- Rinsing down nearby walls, steps and edges
When to Book a Patio Clean
Most people notice the patio before they think about cleaning it. These are the usual signs that a deep clean is worth booking.
Slippery When Wet
Algae builds a green film that turns slick after rain, which makes stepping out of the back door a risk for the whole house.
Weeds in the Joints
Weeds and moss pushing up between slabs loosen the pointing and let more water in, which can start to unsettle the stone.
Black Spots on Stone
Small dark marks that will not shift with a brush are usually lichen, which needs a treatment that works deeper than water.
Selling or Hosting
A clean patio makes a better first impression for house viewings or a summer gathering, without the cost of new stone.

Choosing a Patio Cleaner
Cleaning stone is about knowing when to stop as much as how hard to push. Each patio is assessed for its material and condition before any machine is switched on.
Methods Matched to Your Stone
Sandstone, limestone, porcelain and concrete each react differently to pressure and chemicals, so the approach is set for your slabs, not one setting for all.
