The BR4 stock around Wickham Court and Sparrows Den is inter-war. ONS records 19% flats, 80% houses and 4,862 households in West Wickham.
Private renting sits at 12% and owner-occupation at 83%; the first group books patio and decking cleaning at short notice, the second plans it.
Walls are timber stud partitions inside in BR4, cavity brickwork outside — measured on the walk in from West Wickham (Southeastern) rather than assumed from a map, so the fixing that matters in West Wickham is chosen on site — the usual failure here is in BR4, a four-hole bracket with two screws in a stud and two in fresh air — which is why London Borough of Bromley kerb rules get settled before the van is loaded.
Two streets can behave very differently in West Wickham: a quiet suburb of interwar housing with Coney Hall and Sparrows Den beyond. The quote reflects the street the job is actually on. West Wickham 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: wide roads and driveways; the High Street has timed loading only. West Wickham (Southeastern) is the nearest station, and 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.
