London patio and decking cleaning · South London
Patio and decking cleaning across Merton, from CR4, SM4 and SW19 outwards. Wimbledon's village and tennis, Mitcham's commons and the Wandle valley industry at Colliers Wood, and that is what shapes every quote we write here.

Working in Merton
Merton is built from edwardian villas in wimbledon, 1930s semis in raynes park and morden, and estates around mitcham, and the mix changes street by street — Colliers Wood (SW19), Mitcham (CR4) and Morden (SM4) each behave differently on the day.
On the ground, championship-fortnight restrictions in sw19, hill access to wimbledon village, and driveways common further out. Locally that means high street red route, riverside estate roads and new blocks with booked lifts and tram-line crossings, wide suburban roads and driveways on most streets. Merton sits outside the Congestion Charge zone, so only ULEZ applies to the van and the quote is that much simpler.
Roof terraces and raised decking added to flats across Merton sometimes needed planning permission or a lease variation when they were built, and London Borough of Merton can ask for evidence the drainage still works as designed. We check the deck boards and the drainage outlets are clear before and after cleaning, since a blocked gulley is what turns a clean deck into a leak into the flat below.
Merton Priory and Wandle mills gave way to Victorian and interwar suburbs once the railway reached Wimbledon in 1838. That history is why Merton property behaves the way it does today.

Concrete flag patio, per m² starts at £4.50 in Merton, and the ladder runs up to £7 for the largest job on the table above. Surface material first — natural stone and composite decking cost more per square metre than concrete because both need a lower pressure that takes longer to cover the same area — then access, since a roof terrace with no outside tap needs water carried up rather than run from a hose. The borough is outside the Congestion Charge zone, so there is no charge to pass on — only ULEZ, which our vans are compliant with.
We cover the whole borough: CR4, SM4, SW19 and SW20. On the ground that includes Colliers Wood, Mitcham, Morden, Raynes Park, Wimbledon and Wimbledon Park.
Same-week across every borough, with weekend slots common through spring and early summer when garden and roof-terrace use picks up. South London is covered by crews already working in the borough, so travel time is not billed on top.
Championship-fortnight restrictions in SW19, hill access to Wimbledon Village, and driveways common further out. Where a permit or a bay suspension is needed we arrange it with London Borough of Merton and show the cost in the quote before you agree it. Nothing is added afterwards.
Yes. Edwardian villas in Wimbledon, 1930s semis in Raynes Park and Morden, and estates around Mitcham is exactly the stock we work in daily. Where there is no lift, the crew size is set by the floor level at quote stage, so a third-floor walk-up is priced as a third-floor walk-up rather than re-quoted on the doorstep.
Wastewater containing detergent or biocide is contained and directed away from surface water drains during the clean, and drainage outlets on roof terraces and balconies are checked and cleared as part of the visit. Certificates go out with the booking confirmation, which is what London Borough of Merton tenancies and most local managing agents ask for.
One technician for a standard garden patio or deck; two for a roof terrace or balcony where water has to be carried up by bowser and furniture moved through a lift or stairwell. Vehicles are ULEZ-compliant, which matters in every Merton postcode, and the crew carries everything needed to complete the job in one visit.
Replacing rotten, cracked or delaminating deck boards, Repointing or re-bedding loose or sunken stone slabs and Deep oil or paint staining soaked into porous stone. If something on that list turns up in Merton, we tell you at survey and point you at the right trade rather than taking the booking anyway.

Diana and Alex carried out a deep clean for my property prior to new tenants arriving. The actually cleaning was superb and I would highly recommend them. The only downside was the office and booking system. The poor couple had to travel from Wimbledon to sidcup after waiting for the previous client to attend and… Read in full →
First time using Hello Services within North London and I would highly recommend. Excellent end of tenancy clean, would use again! Thank you!
I asked Hello Services for a deep clean of the carpets of a house in London we were moving into.
