Composite Decking in Finchley: What Works on mid to large gardens; mature trees and London clay are the recurring constraints
Composite Decking in Finchley isn't a bolt-on for us — it's a day-in, day-out install. We cover N3 / N12 and the streets running toward A1000 / A406 North Circular, and we know before we arrive that tree-root activity in clay soil regularly lifts old fence runs — full re-set is the typical brief. That's the first thing that shapes the spec, not the last. Recent work on Squires Lane and East End Road. We orient jobs off North Finchley bus garage. Etchingham Park Road shared rear boundary. Closeboard with capped rail, gravel boards stepped over root run. Re-set the disputed boundary line on a survey-led basis.
