Damp Proofing Question

Our survey has identified potential damp, who is best to say what the remedy is?

The property is approx 100 years old and has 3 spots of damp.

One in the kitchen cupboard, the other 2 are on the same chimney breast, one room above the other - described as seperate pieces of damp.

We don't know what our next move should be? We're not sure if the damp proof course is the problem or if it is some other problem. Should we be asking a damp proof provider or someone else?

thanks

you say that the property is approx 100 years old,properties of this age are usually constructed without physical foundations & are built straight to formation clay,this means that if any dpc originally installed breaks down there is no barrier between the above ground brickwork & clay resulting in rising damp.i would advise that you contact a damp-proofing firm which specializes in plastic membrane dpc installations as chemical injection methods are just not effective in preventing rising damp on this type of construction.
regarding your damp in the kitchen cupboards,you could consider installing a couple of air bricks behind the units to provide air flow,fit 1 at each end of the wall behind units as this increases the flow.
the damp on the first floor will most likely be penetrating damp & it would be wise to check flashings around the stack & also the condition of the stack pointing & pot flaunching.
hope this is some help,good luck

Hi jessandrichard

Damp patches on or around chimney breasts - sometimes showing yellow or brown stains in wallpaper or paint - you have 'hygroscopic' chimney salts that are attracting moisture from the air, which may include tars and other chemicals from burning wood or coal.
I would call on a reputable Damp proofing/Remedial company and maybe seek three quotes.

Good luck
Scott.
