Census 2021 puts Greenford at 12,474 households with a median age of 37.3. The inter-war stock is mixed-tenure, which is why 58% houses and 41% flats need different handling in UB6.
Owner-occupation runs at 53% in Greenford, so alongside the 30% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are solid London stock brick in Greenford, some of it dry-lined during a later refurbishment — the reality on the streets around The Grand Union Canal at Greenford, so the fixing that matters in Greenford is chosen on site — the usual failure here is in UB6, fixings landing in soft lime mortar joints instead of the brick body — measured on the walk in from Greenford (Central) rather than assumed from a map.
Two streets can behave very differently in Greenford: canal-side industry, the Central line's wooden escalator and 1930s semis. The quote reflects the street the job is actually on. Greenford is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: wide roads with driveways; the industrial estates carry heavy traffic at peak. Greenford (Central) is the nearest station, and one fitter for standard windows; two for bent bay tracks or full-height stairwell blinds.
