In South Croydon (CR2) the split is 47% flats to 53% houses over 3,637 households, and the stock is mainly Victorian.
Because 30% of South Croydon is privately rented and 10% socially rented, a lot of CR2 work is agreed with a landlord or managing agent rather than the person opening the door.
South Croydon substrates run to with solid brick on the party and external walls — and lath and plaster over timber studs, which is why London Borough of Croydon kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in South Croydon, which crumbles the key and drops the panel, which is what a 47% flat share across the ONS neighbourhood covering South Croydon actually produces is the mistake that costs a CR2 customer twice.
South Croydon is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — victorian and Edwardian streets on the hill above the town, with Selsdon beyond — which is why a CR2 quote is not a Croydon average.
Steep hills, narrow Victorian frontages and driveways further out. Nearest station is South Croydon (Southern), and two movers as standard, three where a Victorian stair turn, a heavy item or a tight completion-day schedule makes the extra pair of hands worth the hourly cost.
