We can all speculate about why stuff wasn't done earlier but there was no history of damp or condensation at the Twickenham Road house or reports of it by previous tenants and while we all want 'a proper job done' there are limits to what we can reasonably expect in those circumstances.Damp in the floor and walls of the main building was discovered only after the extension was built - the floor had been covered by linoleum which had masked the problem until it was removed and the floor slab included ash in its composition which absorbed moisture and further disguised the presence of damp.  Damp in the walls was masked by the wall coverings - it was yet to show through.  I haven't inspected this house, but I do know how easy it is to miss the signs of damp and this house was apparently not in the state that made the damp as obvious as would have been convenient. As it was, the house became void in September 2011 and was suggested as one that might be suitable for the extensions programme.  It was then assessed, structural/design drawings done and an application made for planning approval.  Work on this extension was completed in May 2012.  The damp was discovered when some minor electrical work was being done in the main building.  It was then investigated during which it was found that (a) there was no damp-proof membrane in the building and (b) the cavity wall had material in it which was bridging the damp-proof course.Arrangements were then made to break up the floor slab, excavate and lay a dpm and recast the floor slab.  After this a suspended timber floor with under-floor ventilation was installed and the plasterwork removed from the ground floor walls and replaced.  I know from my own current experience how long that process can take and I can't fault the time it has taken here.  It is anticipated that the remaining work will still take a further 2-3 weeks - I'm still waiting for my own plasterer to get back with a date to finish his job.
