Damp Proofing

Is injecting damp proof course effective?

I have recently purchased a property and when the survey by our mortgage company was done they advised that the damp proof course was fully effective, no signs of damp on exterior walls or inside of exterior walls. They did pick up on a high damp reading on an interior wall that separates the lounge and dining room. My estate agents then contacted a specialist damp and timber company to have a look. They then sent me a quote to inject a damp proof course into the effected wall, removing the plaster back to the brick, injecting and replastering. This has been done about 7 weeks ago and so far so good. However, I was by chance talking to another damp company the other day and over the phone the bloke told me that just injecting the affected wall would not work as the damp would go somewhere else, and that surveys done by damp specialists associated to the estate agents was not a good idea and that I could have much greater problems. He concluded over the phone without inspecting my property that I would need a whole new damp proof course. I am really concerned that the treatment that they have done will not work after what he has said but on the other hand my independent survey by mortgage company said the damp proof course is fully effective. The previous occupant used to dry her washing in the house all the time could the damp be due to condensation? The damp was on the bottom of the interior wall, just moist with no smell of mould etc. Would appreciate any advice!
