I would also like to add my recommendation for Dave Reilly for dealing with damp issues. He has done fab work for us in remedying small damp problems around the front bay window and cellar, and recently came out within 24 hours of my email to diagnose damp trouble in a house we have surveyed and are in the process of buying. He completely puts our minds at ease, and is refreshingly honest and no-nonsense. Thanks Dave! Corinne, Nunhead
