Building size and façade area. Cost is generally priced per square metre of façade, so height, footprint and elevation complexity all matter more than the number of storeys alone.
Cladding type. ACM removal and replacement carries different cost and disposal implications to rainscreen, HPL or render — some materials require specialist handling.
Extent of replacement. A like-for-like recladding project prices differently to one that also involves upgrading insulation, cavity barriers or fire stopping behind the cladding.
Access. Scaffolding, mast climbers and MEWPs (mobile elevating work platforms) are a significant line item, particularly on taller or more complex buildings, and access strategy is usually one of the first things we price.
Fire stopping and cavity barriers. Where remediation extends beyond the visible cladding into compartmentation and fire stopping, this adds scope — but it’s often non-negotiable from a building safety standpoint.
Insulation. Replacing or upgrading insulation as part of the works affects both material cost and thermal performance outcomes.
Design and professional fees. Structural engineers, façade engineers and fire consultants are typically involved before a single panel comes off the building — see façade remediation design.
Project stage you’re starting from. A project that already has a survey, strategy and design in place will price more accurately than one starting from a fire risk assessment alone.
