Census 2021 puts Sydenham at 9,790 households with a median age of 36.9. The mainly Victorian stock is social-housing-led, which is why 36% houses and 64% flats need different handling in SE26.
Owner-occupation runs at 45% in Sydenham, so alongside the 22% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are often with surface conduit — and precast concrete panels and dense blockwork — which is what a 64% flat share across the ONS neighbourhood covering Sydenham actually produces, so the fixing that matters in Sydenham is chosen on site — the usual failure here is in SE26, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Sydenham (Overground) rather than assumed from a map.
Two streets can behave very differently in Sydenham: a long high street on the hill where the Crystal Palace once stood nearby. The quote reflects the street the job is actually on. Sydenham 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: steep hills, high-street loading windows and narrow side streets. Sydenham (Overground) is the nearest station, and two crew and a Luton on most strip-outs; three crew and a tipper where the load is rubble, hardcore or soil and weight rather than volume decides the run.
