Blocked Cavities, Low Air Bricks, South-Facing Damp: How Proofterior Brought a Bournemouth Home Back to Life with Chemical DPC and ISO-THERM.
Cavities cleared, air bricks raised, new damp proof course, passive vent, and ISO-THERM for warmer, dry rooms in this Bornemouth Property.
South-Facing Walls and Stubborn Damp: Why It Kept Coming Back
A Bournemouth homeowner reported bubbling paint, salty staining and winter mould along south-facing walls. Heat on the façade met poor subfloor ventilation, so moisture tracked through blocked cavities and low air bricks that sat too close to ground level. Without removing these causes, cosmetic repairs would fail and the property would keep showing damp.
Evidence First in Bournemouth: A Damp Survey That Turns Clues into a Clear Plan
Our damp specialists carried out a full damp survey in this property in Bornemouth with mapped moisture readings, cavity checks and ventilation assessment. Salts tests supported the pattern, confirming long-term transfer rather than a one-off spill. In the spirit of Awaab’s Law, we treat damp and mould as health priorities, so the plan focused on fixing sources outdoors first, then completing internal proofing that lasts.
The Solutions: Stop Moisture Outside, Protect Finishes Inside
Inside, we hacked back affected plaster to sound substrate, neutralised the walls to control salts, and injected a new chemical damp proof course along the problem runs. Two key walls were plasterboarded and skimmed to a smooth, ready-to-decorate finish. This targeted sequence removes contaminated material, blocks rising moisture, and hands back a clean surface that will keep its paint.
Everyday Humidity Under Control: Passive Vent and ISO-THERM for Warmer, Drier Walls
The bathroom was a condensation hotspot, so we fitted a new passive air vent to keep humid air moving. We also applied ISO-THERM thin internal wall insulation to the cold external Bornemouth Property walls, lifting surface temperature and helping to deter mould. Ventilation plus ISO-THERM creates day-to-day comfort, reducing the chance that ordinary living will undo the repairs.
The Result: Dry Readings, Warmer Rooms, A Finish That Lasts
After the works, we re-tested during wet weather and on a warm day. Readings sat back in the normal range, the moisture profile stayed stable, and no new staining appeared. That is because we removed the causes, not just the marks. Cleared cavities now drain as designed, raised air bricks keep fresh air moving under the floor, the chemical DPC blocks rising damp in Bournemouth, salt neutralising stops old contamination reappearing, and inside the home the passive vent and ISO-THERM help everyday humidity disperse instead of settling on cold walls.
The client received a fixed, written report with photos, our workmanship guarantee, and simple aftercare so the results will last. This is how Proofterior does damp proofing properly, from evidence-led survey to targeted repairs and a finish you can repaint with confidence.
