CONDENSATION A CASE STUDY ALAN MCKEOWN MA ASSOCRICS DIPRSV, PLUMB STONE SURVEYORS
In this article, Alan McKeown, Building Surveyor at Plumb Stone Surveyors, shares a case study of a non-invasive damp survey he carried out. The scope of the survey, requested by the landlord of the property, was to determine the cause and extent of any dampness and recommended repairs. The property
The wall construction was solid brick with a pitched roof covered in the original plain clay tiles. There is an extension to the rear and an attached outbuilding. The property was renovated around five years ago, including damp-proofing measures to the floors and main walls. The main walls were lined internally with insulated plasterboards. The property was in generally good condition, with some maintenance required to clear rainwater gullies and gutters. Biological growth was evident at the base of the main walls.
