  • Breathable Lime are lime plastering and damp specialists for Victorian, period and listed homes across south and east London, Kent and Essex. Most damp in older properties isn't rising damp. It's moisture trapped in the walls by cement render, gypsum plaster and vinyl paints. Victorian homes have solid walls built to absorb a little moisture and let it evaporate. Modern, impermeable materials break that cycle, causing persistent damp, black mould, blown plaster and cold, musty rooms. We fix the root cause. Using Breathaplasta, a modern hemp lime plaster by Adaptavate, we restore your walls' breathability without cement, gypsum or plastics. It regulates moisture, resists mould, flexes with the building and sets in around two hours per coat, so it's far quicker and less disruptive than traditional lime. Every job starts with diagnosing the real cause of the damp. No unnecessary chemical damp-proof courses, injected treatments or tanking, just honest advice and a permanent, breathable solution. Free, no-obligation quotes.
