Damp Proofing in Northwood

Extensions such as garage conversions will usually require additional damp proofing to be added as part of conversion, as the existing garage will typically have a single skin design for walls and floors, which was not built to comply with 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 of the floor of the garage conversion will often be achieved by utilising 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, underneath the new floor, or as part of both, depending on whether the floor will be a solid or a floating floor. In a few garages, the walls have been damp proofed, but this may have to be improved as part of the conversion to be able to meet 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 performed by either implementing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is an important part of the building regulations that the garage conversion should adhere to, therefore is it important to make sure that your garage conversion employs appropriate damp proofing methods.

FAQs

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

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.

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!
