The BR7 stock around Chislehurst Caves and the commons is mainly Victorian. ONS records 21% flats, 79% houses and 9,685 households in Chislehurst.
Private renting sits at 14% and owner-occupation at 77%; the first group books blinds and curtain fitting at short notice, the second plans it.
Chislehurst substrates run to timber stud partitions inside; locally that also means cavity brickwork outside — the reality on the streets around Chislehurst Caves and the commons. Nothing is drilled until the wall has been sounded, because in BR7, 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 is the mistake that costs a BR7 customer twice.
Two streets can behave very differently in Chislehurst: commons, caves and a village of large houses on the Kent border. The quote reflects the street the job is actually on. Chislehurst is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Common-side lanes are narrow; most homes have long private drives. Nearest station is Chislehurst (Southeastern), and one fitter for standard windows; two for bent bay tracks or full-height stairwell blinds.
