Hounslow substrates run to solid London stock brick in Hounslow, some of it dry-lined during a later refurbishment — the reality on the streets around Hounslow Heath. Nothing is drilled until the wall has been sounded, because in TW3, fixings landing in soft lime mortar joints instead of the brick body — measured on the walk in from Hounslow Central (Piccadilly) rather than assumed from a map is the mistake that costs a TW3 customer twice.
Two streets can behave very differently in Hounslow: a long pedestrianised high street, the heath and airport-adjacent housing. The quote reflects the street the job is actually on. Hounslow is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Pedestrianised high street with timed access; new blocks need booked lifts. Nearest station is Hounslow Central (Piccadilly), and standard crews are two people with a 3.5-tonne Luton; bigger clears run two vans or return the same day rather than overfilling.
