Understand the signs
What rising damp can look like
Rising damp is moisture moving upwards through porous masonry from the ground. Other building defects can create very similar symptoms, so the cause should be tested rather than assumed.
Ask us about your property →A low “tide mark”
Discolouration or dampness beginning at floor level, often below about 1 metre.
Salt deposits
White, powdery salts on plaster or masonry as moisture evaporates.
Damaged finishes
Blistering paint, crumbling plaster, lifting wallpaper or decayed skirting.
A persistent pattern
Symptoms that remain despite normal heating and ventilation.
Avoid an expensive misdiagnosis
It may not be rising damp
High ground levels, leaking pipes, penetrating rain and condensation can all mimic it. A survey should test the diagnosis—not assume it.
Ground & drainage
Bridged damp-proof courses, raised paths and poor drainage can keep a wall wet.
Leaks & rainwater
Plumbing, gutters, roofs and external defects often create local damp patches.
Condensation
Cold surfaces and limited ventilation can cause mould and damp at low level.
What happens on site

07737 040472How high does rising damp usually reach?
It is usually most visible at low level. Height alone cannot confirm the cause.
Does mould prove I have rising damp?
No. Mould is commonly associated with condensation and limited ventilation.
Will I definitely need a new damp-proof course?
No. Treatment should follow diagnosis. Sometimes the right fix is lowering external ground, repairing a leak or improving rainwater disposal.
