The homeowner was told by multiple companies that they had rising damp and needed chemical injections
What We Found:
External ground levels were too high and bridging the DPC
The subfloor had almost no airflow
Humidity inside the home was extremely high
Condensation was forming on cold walls and being misdiagnosed
The Solution:
Lowered ground levels
Restored airbrick ventilation
Installed a PIV system
Upgraded bathroom extraction
Result:
Walls dried naturally, mould disappeared, and the injections were proven unnecessary
