The EC4 stock around Blackfriars Bridge and the Thames-spanning station is mixed-era. ONS records 98% flats, 2% houses and 4,914 households in Blackfriars.
Private renting sits at 48% and owner-occupation at 37%; the first group books spring cleaning at short notice, the second plans it.
Blackfriars substrates run to dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms — where 37% owner-occupation means the same home is booked again rather than a new tenant each year. Nothing is drilled until the wall has been sounded, because in EC4, short screws that grip only the board and slowly lever it off the dabs — with 15% social-rented stock locally, block access is agreed with the estate office first is the mistake that costs a EC4 customer twice.
Two streets can behave very differently in Blackfriars: riverfront offices and legal quarter streets running up to Fleet Street. The quote reflects the street the job is actually on. Blackfriars sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Embankment red route with no stopping; access is via the side lanes with a permit. Nearest station is Blackfriars (Circle, District, Thameslink), and two cleaners for a flat, two to three for a house, working together in one visit rather than spreading the job across days.
