Our Damp Specialists

Our team of damp specialists will always keep you in the loop and will be able to recommend the best course of damp proofing for your specific property.

Rising Damp & Damp Proofing

Rising damp is often only detected when a property is ‘surveyed’ during a sale or purchase, which means damp may not be visually dramatic. However, if rising damp is left untreated, it can cause significant structural problems and lead to other issues such as wet or dry rot in floors or joinery.  This is often the case when the problem has been present for some time as a result of the floor voids not being well ventilated with sufficient air bricks. Treatment of rising damp typically requires removal of the skirting boards and internal plaster, followed by the installation of a new damp proof course. Once this has been installed, we replaster the walls with a waterproof specialist plaster.

Alternatively, penetrating damp due to leaking gutters and down pipes may have been left unrepaired for many years and can cause plaster to fail and rot to occur. Where such dampness occurs, an inspection of the extent of the problem and the condition of the adjacent timbers is recommended to provide an accurate evaluation of the most appropriate damp treatment.
