In Teddington (TW11) the split is 46% flats to 54% houses over 10,821 households, and the stock is mainly Victorian.
The owner-occupier-led mix here (65% owned, 25% privately rented) means a TW11 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Teddington substrates run to with solid brick on the party and external walls — and lath and plaster over timber studs, and narrow high street with timed loading; residential roads mostly have driveways. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in Teddington, which crumbles the key and drops the panel, which is what a 46% flat share across the ONS neighbourhood covering Teddington actually produces is the mistake that costs a TW11 customer twice.
Teddington 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 — the lock, a village high street and Bushy Park on the doorstep — which is why a TW11 quote is not a Richmond upon Thames average.
Getting to the door matters as much as the job: narrow high street with timed loading; residential roads mostly have driveways. Teddington (South Western) is the nearest station, and two to four operatives for a single-building clear, scaling to two teams working in parallel where a full primary site has to be finished inside a two-week holiday window.
