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 patio and decking cleaning at short notice, the second plans it.
Blackfriars substrates run to with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork — which is what a 98% flat share across the ONS neighbourhood covering Blackfriars actually produces. Nothing is drilled until the wall has been sounded, because short screws that grip only the board and slowly lever it off the dabs on these streets — measured on the walk in from Blackfriars (Circle, District, Thameslink) rather than assumed from a map 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 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.
