Census 2021 puts Monument and Eastcheap at 4,914 households with a median age of 36.9. The recent new-build stock is renter-heavy, which is why 2% houses and 98% flats need different handling in EC3.
Private renting sits at 48% and owner-occupation at 37%; the first group books driveway cleaning at short notice, the second plans it.
Walls are dot-and-dab plasterboard over blockwork in EC3, with metal stud partitions between rooms — which is why City of London Corporation kerb rules get settled before the van is loaded, so the fixing that matters in Monument and Eastcheap is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs on these streets — measured on the walk in from Monument (Circle, District) rather than assumed from a map.
Two streets can behave very differently in Monument and Eastcheap: riverside City streets between London Bridge and the Tower, dense with narrow lanes. The quote reflects the street the job is actually on. Monument and Eastcheap sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Getting to the door matters as much as the job: lower Thames Street is a red route; the lanes behind take a small van only. Monument (Circle, District) is the nearest station, and one technician and a van-mounted hot-water pressure washer for most driveways; two on larger block-paving jobs where re-sanding is included, since brushing sand in is a second task run alongside the wash.
