The Service
Patio stone is softer and more porous than block paving. Sandstone in particular is famous for biofilm — that black tide line that creeps in from the joints. The instinct is to crank up the pressure, but high pressure on stone causes 'banding' — visible stripes where the surface has been etched.
Our patio cleaning service uses hot water (80°C), biocide pre-treatment and a rotary surface cleaner at controlled pressure. The heat does the work, so the pressure stays gentle and the stone stays unharmed. Failing joints are repointed, and we offer impregnating sealers that stop the staining coming back for 3-4 years.
It's right for any homeowner who's looked at the patio in May and thought 'we used to use that'. Most jobs are done in a single visit, and the difference is dramatic.
Why It Matters
Patio cleaning is the most-damaged surface category we see. Here's why.
High-pressure DIY washers leave visible banding on sandstone and limestone. Once it's etched, it's etched — no amount of further cleaning brings the surface back.
Pressure straight into mortar joints destroys them. Cracked, missing or 'lacy' mortar means water gets under the slabs and the patio starts to fail.
Without proper repointing and either polymeric jointing or sealing, the moss is back in a single season — usually worse than before, because pressure has opened up the joints.
Brick acid on a sandstone patio is a common mistake — it permanently bleaches the stone and triggers efflorescence that won't go away.
Our Process
01
Fixed price by m² after a photo or short visit — we identify the stone type so we know exactly what pressure to use.
02
Algae and biofilm killed with a stone-safe biocide. 10-15 minute dwell time before any wash.
03
80°C water at controlled pressure with a surface cleaner attachment — no banding, no stripes, no edge damage.
04
Failing mortar removed and joints repointed with patio jointing compound (kiln-dried sand and resin).
05
Impregnating sealer applied if booked, surface dried, full walk-through and sign-off before we invoice.

In Detail
Every stone has its own personality. Here's how we treat each — and the sealers and jointings that go with them.
Hot water at 100-130 bar with a surface cleaner — never lance work. Biocide pre-treatment (stone-safe — not patio cleaner that contains acid). Optional impregnating sealer (Lithofin MN Stain-Stop) gives 3-4 years of protection from re-staining.
Pressure isn't the issue with porcelain — the slab itself is virtually maintenance-free. The vulnerable area is the jointing between slabs. We clean the surface gently and inspect/repoint joints with the appropriate jointing compound.
Robust under hot-water rotary. The main issue with concrete is fading colour — once cleaned, an optional coloured sealer can restore the original tone.
Soft, low pressure, hot water, neutral pH cleaner. Slate scratches easily, so the surface cleaner is held off the surface, never dragged. Slate-safe sealer available.
Old mortar removed to 20mm depth, joints washed clean, then repointed with either traditional sand-and-cement mortar (3:1 sharp sand to cement) or polymeric jointing compound for flexibility. Polymeric is better for joints over 5mm wide; mortar is better for tight joints.
Impregnating (penetrating) sealer keeps the natural look but blocks staining — recommended for sandstone and limestone. Wet-look sealer deepens colour and adds gloss — for concrete and where the customer wants a 'just-laid' look. Both 3-4 year life.
Moved before we start, cleaned underneath, plant pots wiped down on the base before going back. We also clean external dining furniture for an extra £20-£40 if asked at the same visit.
Pub gardens, holiday-let patios and hotel courtyards on rolling maintenance programmes. Out-of-hours work available so we don't disrupt customers.
