Spray Foam Removal Cost Guide for London Lofts

Spray foam removal from London lofts typically costs £3,200 to £7,800 for an average 40–60 m² space. This range reflects the realities of Victorian and Edwardian terraces common in South Woodford and Leyton, where limited loft access and older timber structures increase labour time.

Damp winters accelerate mould growth beneath the foam, adding assessment steps before work begins.

These conditions push the upper end of the £3,200–£7,800 range when the job spans multiple visits.

Medium 40–60 m² spaces common in Barkingside semi-detached homes average £4,800–£6,200. Larger 70 m²+ lofts in Manor Park require £6,500–£7,800 because of extra waste removal and scaffolding needs on narrow streets. Each figure includes site protection, foam extraction and basic disposal.
