Damp Proofing in Swansea

Extensions including garage conversions will often require extra damp proofing to be added through the conversion, as the existing garage will typically have a single skin design for walls and floors, which was not built to conform to building regulations for habitable rooms. This damp proofing will have to be added to walls and floors. Moreover, the roof of the garage conversion will require water proofing. The damp proofing for the floor of the garage conversion will most likely be performed by by using a damp proof membrane. This membrane will come in either solid or liquid form. The damp proof membrane will be put down either on top of the existing concrete floor, underneath the new floor, or as part of both, depending on if the floor will be a solid or a floating floor. In some garages, the walls have already been damp proofed, but this may need to be updated as part of the conversion to be able to comply with current building regulations. The walls should be damp proofed in order to safeguard the brickwork from rotting gradually as moisture sets in. This is performed by either using damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already present in the garage. Damp proofing is an integral part of the building regulations that the garage conversion should adhere to, therefore is it important to make sure that your garage conversion incorporates suitable damp proofing methods.

How can I tell if my property has damp?

These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.

How quickly can I redecorate my walls after damp proofing has been installed?

You should make sure that all signs of damp have gone before you redecorate your walls. If you want to paint your walls with a water-permeable emulsion paint, you can usually do this after 1 or 2 months. For other types of decoration you should wait longer.

Why is it important to fix a damp problem?

Damp is a serious problem, particularly if you live in an old property, because it can lead to structural damage. This will cost you big money and could be very dangerous, to yourself and the property. Take damp seriously and get it inspected and resolved as soon as you discover it!
