Common problems
Failed Damp Proof Course
You have been told the damp proof course has failed, and want to know what that means and whether it is true.
Is It Condensation Or Damp?
A hygrometer and a log of when the damp appears tell you more than one damp meter reading. A survey puts the evidence together, and the answer decides whether you need ventilation or building work.
Damp Or Mould After Cavity Wall Insulation
Contact the installer first and check the guarantee paperwork. A damp survey should find the cause before the insulation is blamed or removed.
Damp In A New Extension Or Converted Garage
Damp in an extension is often at the join with the old house or in a floor that has no working membrane. The builder or building control sign-off may help.
Damp Under The Stairs Cupboard
The cupboard under the stairs is often the coldest, least ventilated part of the ground floor, over a floor nobody dampproofed. Find out whether it is condensation, the floor or a leak.
Damp Concrete Floor Or Damp Carpet On The Ground Floor
A damp ground-floor slab usually has no damp proof membrane, or a failed one. Lift a corner of the covering before deciding between a membrane and a leak.
