Tackling damp - service available in Shackleford - GU8 area
We know that the term “damp” strikes fear into most homeowners. Left untreated, a small, easily to fix problem can become much larger and considerably more expensive to repair. The presence of damp is usually signalled by obvious visual clues such as discolouration of surfaces, mould, peeling paper, or crystallised salts on plaster. Surfaces may be damp to the touch and the smell of a damp room is always obvious on entry. There are 3 main types of damp: condensation, penetrating damp and rising damp. Mould in bathrooms and kitchens (and sometimes in other rooms) is often result of condensation. If there is a lot of moisture in the air, droplets will form on cold windows, cold water pipes and cold external walls. We can prevent mould by improving the ventilation in the room and removing the mould stains with a fungicide or bleach solution.
The penetrating damp, which penetrates the house from the outside, can show itself anywhere on an internal wall after wet weather. As this takes a long time to dry out, the penetrating damp causes staining and damages to the surfaces. A well known issue for penetrating damp is a leaking guttering which can saturate a wall that is not designed to withstand (soil piled up against a wall is another cause).We fix this using 2 solutions:
- Applying an epoxy damp-proof membrane, or
- Fitting a polypropylene membrane.
Rising damp enters the house from the ground and is generally caused by the damp-proof course or damp-proof membrane falling. If the floor has been damaged by rising damp, a new one will have to be fitted in which will include a damp-proof membrane too. But, the most often, the problem is in the walls, where we install a new damp-proof course, which is best achieved using a chemical-injection system:
1). Non-presurized injection of DPC;
2). Pressurised injection of DPC.
