The TW3 stock around Hounslow Heath is mainly Edwardian. ONS records 43% flats, 57% houses and 18,207 households in Hounslow.
Owner-occupation runs at 43% in Hounslow, so alongside the 40% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are solid London stock brick in Hounslow, some of it dry-lined during a later refurbishment — which is what a 43% flat share across the ONS neighbourhood covering Hounslow actually produces, so the fixing that matters in Hounslow is chosen on site — the usual failure here is in TW3, fixings landing in soft lime mortar joints instead of the brick body — which is why London Borough of Hounslow kerb rules get settled before the van is loaded.
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 one technician for domestic hoods and bathroom fans; two for island canopies and any commercial kitchen.
