Pre-1919 and solid-wall homes weren't built to be sealed — they were built to breathe. A "damp-proofing" fix designed for a modern cavity wall can trap moisture in a traditional wall and make things measurably worse.
Solid walls, lime render and plaster, timber, and natural ventilation all work together to manage moisture by letting it move — not by stopping it. Most damp problems in older homes trace back to a modern material or method that interrupted that movement: cement render, gypsum plaster, cavity fill, sealed floors.
Not a generic modern damp survey applied to an old building.

For homeowners of pre-1919 and solid-wall properties considering insulation or energy improvements — understand what your building can safely take before you commit, underpinned by the NOCN L3 EEMOTB qualification. Diagnosis only, as always: no retrofit works sold.
Energy efficiency for traditional homesKnow what you're taking on before you commit — construction type, moisture risk, and what needs attention first.
If damp keeps coming back despite previous "fixes," the cause is usually a material mismatch, not a lack of treatment.
Understand what your walls can safely take before choosing an insulation approach — before it's built in and hard to undo.
