Hillingdon's north is Metroland proper. The Metropolitan line pushed 1920s and 1930s semi-detached suburbia across Ruislip, Eastcote, Ickenham and Northwood, built when asbestos cement was standard for garage roofs, soffits, rainwater goods, cold water tanks and garden outbuildings — these remain the most consistent residential asbestos finds anywhere in the borough.
The south tells an industrial story. Hayes was one of interwar Britain's great manufacturing centres — home to the EMI works and a dense belt of factories along the Grand Union Canal — while Uxbridge, Cowley and West Drayton developed their own trading estates through the mid-20th century. Corrugated asbestos roofing, sprayed coatings to steelwork, pipe lagging and insulating board partitions are routine in this stock, much of which is now being converted to housing and logistics space.
The Heathrow corridor keeps the borough's commercial property in constant motion: hotels, warehouses, offices and airport-support premises across Harlington, Harmondsworth and West Drayton are continuously refitted and redeveloped. Every pre-2000 building in that cycle legally requires a refurbishment and demolition survey before works — making Hillingdon one of the steadiest sources of commercial survey demand in west London.
