Patio Cleaning in Cheltenham& the Cotswolds — stone, slaband porcelain, properly restored.
A clean patio adds an entire outdoor room back to your home. We use the right pressure for your stone — Indian sandstone, Cotswold stone, porcelain or slab — lift the moss, algae and BBQ-season staining, and re-sand or reseal where needed.
Patio Cleaning — done properly, the first time.
A professional patio clean removes algae, moss, lichen and ingrained staining from your outdoor stone or paving without damaging the surface. We follow with optional re-jointing — mortar or polymeric — and an optional sealant to extend the clean for years.
Suited to homeowners with Indian sandstone, Cotswold stone, granite, slate, porcelain, concrete slab or natural stone patios across Cheltenham, Gloucester and the Cotswolds.
Best in spring through early autumn, when the surface dries quickly afterwards. Visible signs you're due: green tint after rain, slippery surface in autumn, dark moss patches in corners, BBQ grease stains from summer entertaining.
A well-laid stone patio represents £3,000–£10,000+ of original cost. Cleaning every 2 years preserves both appearance and the actual stone surface — neglected patios stain and pit irreversibly.
The cost of putting it off.
Outdoor stone weathers in plain sight. Algae makes the surface slippery, moss roots into joints and lifts slabs out of level, BBQ grease soaks into porous stone, and rust from garden furniture leaves marks that don't simply wash off.
Real risks
- Slip hazards in autumn and winter — patios are a common source of household falls.
- Joint failure as moss roots lift mortar or polymeric jointing.
- Slab movement under foot traffic when bedding sand is undermined by water tracking.
- Permanent staining from BBQ grease, oil drips and red wine if left to bake in summer sun.
- Lichen pitting on Cotswold stone — purely cosmetic damage that no clean can undo once advanced.
Common mistakes
- Treating porcelain with the pressure used for concrete — pitting and edge damage in a single pass.
- Using bleach, which kills surface algae but discolours stone and runs into beds and ponds.
- Holding a domestic pressure washer too close to natural stone, scoring permanent lines into the surface.
- Skipping re-jointing — joints fail within a year, slabs move within two.
- Pressure washing slate-bedded slabs and washing the bedding sand out from under them.
A clear, five-step system.
-
01Step 1 — Inspection
We walk the patio, identify the material, note staining, joint failure, slab movement and any drainage issues.
-
02Step 2 — Diagnosis
Pressure, nozzle and chemistry selected for your specific stone. Adjacent beds, ponds and furniture protected.
-
03Step 3 — Service execution
Pre-treat moss, then surface-safe pressure wash with rotary cleaner on open areas and hand-lance on edges and steps.
-
04Step 4 — Joint repair & verification
Failed joints raked out and refilled with kiln-dried sand or polymeric compound. Loose slabs reseated where possible.
-
05Step 5 — Completion & optional seal
Optional impregnating sealer applied once the surface is dry. 6-month satisfaction guarantee.
What you actually get for your money.
Concrete outcomes — not marketing claims. Every benefit below is verified on every job we leave.
Patio you can actually use again
No more slippery surface or unsightly green patches when guests arrive.
Safer underfoot all year
Algae stripped from the surfaces you actually walk on.
Joints repaired, not just washed
Failed jointing replaced rather than left to crumble through another winter.
Stains genuinely lifted
Hot-wash and the right chemistry pull out BBQ grease, oil and wine that won't shift with a hose.
Stone preserved long-term
Surface-safe pressure means no pitting, no scoring, no premature wear.
Optional seal doubles the result
Impregnating sealant extends the clean to 3+ years and keeps stains at the surface.
The technical detail behind every patio cleaning job.
Patios are the most chemically and physically varied surface we clean. The same equipment that perfectly suits concrete will destroy porcelain. Knowing what you're standing on — and treating it accordingly — is everything.
£2m public liability, full RAMS, certificates on request before any booking is confirmed.
Materials we work on
We work across every common UK patio material: Indian sandstone (riven and sawn), Cotswold limestone, granite setts, slate, porcelain, concrete slabs (Marshalls, Bradstone), exposed aggregate, brick paviors and natural flagstone. Each has its own porosity, hardness and finishing requirement.
Methods we use
Pre-treatment of moss with an approved biocide where needed. Surface-safe pressure wash using a rotary cleaner on the open field and a precision hand-lance on edges, steps and joints. Joint repair with kiln-dried sand for sand-jointed work, or polymeric compound for sealed joints. Hot-water unit deployed for grease and oil staining. Optional impregnating sealer (penetrating, not surface-film) once dry.
Variations of the service
Standard patio clean, clean + re-joint, clean + re-joint + seal, BBQ grease specialist treatment, lichen removal on Cotswold stone, decking clean as a separate service.
Situations it applies to
Pre-summer entertaining refresh, post-builder clean-up, annual maintenance for second homes and lets, ahead of weddings and garden parties, and post-winter recovery cleans across the Cotswolds.
Residential vs commercial
Residential is photographed, joints repaired, beds protected. Commercial hospitality and care-home outdoor areas scheduled out of opening hours with full RAMS and signage.
