Damp Proofing in County Antrim

Extensions including garage conversions will often require supplementary damp proofing to be installed during the conversion, as the existing garage will typically have a single skin design for walls and floors, which was not manufactured to be in accordance with building regulations for habitable rooms. This damp proofing should be put into walls and floors. Additionally, the roofing of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will usually be performed by employing 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 existing concrete floor, below 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 will have already been damp proofed, but this may need to be updated as part of the conversion in order to adhere to current building regulations. The walls will need to be damp proofed to be able to protect the brickwork from rotting gradually as moisture sets in. This is done by either making use of 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 comply with, therefore is it necessary to make sure that your garage conversion makes use of suitable damp proofing methods.

FAQs

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.

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!
