We handle the structural, technical and practical side of basement projects. Strength, reliability and construction expertise: that is the whole offer.
Wentworth Basements is a specialist basement contractor working across London and the South East. We focus on the technical side of basement construction: excavation, structural concrete, steel fixing, and waterproofing. We keep the work in-house.
That means one site team, one point of contact and one chain of responsibility. No gaps between trades, no finger-pointing when something needs putting right, and no surprises at handover.
We work as a main contractor on residential basement builds and as a specialist sub-contractor for commercial main contractors. The standard is the same either way.
