In Hainault (IG6) the split is 25% flats to 75% houses over 5,741 households, and the stock is post-war.
Because 17% of Hainault is privately rented and 25% socially rented, a lot of IG6 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are solid London stock brick in IG6, some of it dry-lined during a later refurbishment, the pattern behind 5,741 households inside the IG6 neighbourhood, so the fixing that matters in Hainault is chosen on site — the usual failure here is Hainault gives us fixings landing in soft lime mortar joints instead of the brick body, and with 17% of homes here privately rented, it sets the booking date as often as the job does.
Hainault 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 — post-war LCC estate housing beside Hainault Forest Country Park — which is why a IG6 quote is not a Redbridge average.
Getting to the door matters as much as the job: wide estate roads with easy parking and level access to most homes. Hainault (Central) is the nearest station, and one technician for a private path; two where a communal walkway has to stay open to residents while the work is done, so one can manage access while the other washes.
