Damp problems again!!!

Hi All, More damp questions - apologies for boring anyone. The background - my living room has damp problems mainly on two walls- it rises up to within a foot of the coving. 1870s house solid walls.I've done all the usual checks. It's not condensation and there isevidence it's been a problem before. Ground level is below both theslate dpc and the silicon DPC. Room 25ft by 10ft.Recently had a quote by a damp company (~£3K) to do the following; - Inject DPC (already has a silicon one and a slate one) - Strip plaster on two walls (total 35ft inc 3 windows andfrenchdoors)- Treat the two walls with some sort of waterproofing "stuff" - Replaster two walls- Remove bottom 6" of external render and rerender with bellcast. - Repoint two courses of bricks (35ft) below the DPC. My plan is to get them to do the DPC (and wall treatment???) and I'lldo the rest. I appreciate the injected DPCs are not trusted by manybut I want to give this work every chance of fixing the problem.For the internal walls; - Should I plaster or use plasterboard with a skim? Damp Companydidn't like the idea of plasterboarding as it causes problem with thewall treatment.- If I plaster, what type(s) of plaster should I use? I would getsomeone in to do this.- If I plasterboard it presumably celotex could be used to aidinsulation?- Could I "dot 'n dab" plasterboard direct to the wall? - Should I treat the bare brick in any way prior to this? - Do I need to give the walls time to dry out? - If so roughly how long? For the external walls; -What mix of render? -Any tips with the bellcast beading? How far above the DPCs should itbe?-What mix for repointing below the DPC? -What mix for repointing above the DPC? Incidentally, I am getting a few more quotes!!All experiences/advice welcome...Cheers, Martin.

So a six sided structure could be a vacuum?
