Damp Proofing in Cwmbran

Extensions such as garage conversions will typically require supplementary damp proofing to be added during the conversion, as the existing garage normally has a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing will have to be added to walls and floors. Additionally, the roof of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will in most cases be performed by using a damp proof membrane. This membrane can come in either solid or liquid form. The damp proof membrane will be put down either on top of the pre-existing concrete floor, underneath the new floor, or as part of both, depending on whether the floor will be a solid or a floating floor. In some garages, the walls will have already been damp proofed, but this may have to be improved as part of the conversion in order to comply with current building regulations. The walls will need to be damp proofed in order to protect the brickwork from rotting slowly as moisture sets in. This can be done by either applying damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already present in the garage. Damp proofing is a part of the building regulations that the garage conversion will need to adhere to, and so is it necessary to ensure that your garage conversion incorporates suitable damp proofing methods.

FAQs

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!

How can I tell what type of damp I’ve got?

Signs of rising damp tend to be close to the ground, usually no higher than a metre. It usually works its way up walls in horizontal lines. Penetrating damp usually develops in patches and can often be much higher up. For more advice, speak to a damp proofing professional.

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.

How can I tell if my property has damp?

There are a few visible signs of damp, although it often goes undetected. However, in older or empty properties, this made become detectable through its smell. These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.
