On multi-storey blocks, schools, institutional and commercial buildings, we work by rope access where scaffolding is impractical, disproportionately expensive, or cannot physically reach a face. Painters descend the elevation on ropes and work it in sequence — wash, repair, sealer, then the coats — the same specification as any other exterior job, just reached differently.
It suits narrow gaps between blocks, courtyards and atriums, occupied buildings where scaffolding would block circulation, and elevations where only part of the face needs work. Scaffolding is still the right answer on many jobs; the access method is decided per elevation at the site assessment and written into the quotation, so you can see what was chosen and why.
