Census 2021 puts Roehampton at 9,539 households with a median age of 33.4. The inter-war stock is social-housing-led, which is why 25% houses and 75% flats need different handling in SW15.
Private renting sits at 25% and owner-occupation at 35%; the first group books pathway jet washing at short notice, the second plans it.
Roehampton substrates run to precast concrete panels and dense blockwork in SW15, often with surface conduit — a median age of 33 in this neighbourhood shapes what gets ordered here. Nothing is drilled until the wall has been sounded, because in SW15, drilling blind into a panel with reinforcement or a buried cable behind it — with 40% social-rented stock locally, block access is agreed with the estate office first is the mistake that costs a SW15 customer twice.
Two streets can behave very differently in Roehampton: the Alton Estate's modernist slabs beside Richmond Park's Roehampton Gate. The quote reflects the street the job is actually on. Roehampton is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: slab blocks with limited lifts, long walkway carries and steep estate approaches. Barnes (South Western) is the nearest station, and one technician for a private path; two where a communal walkway has to stay open to residents while the work is done, so one can manage access while the other washes.
