hevydevy   10 #1 Posted April 21, 2011 Hi,  we have small levels of damp on one of internal walls, was wondering roughly how much per metre this would cost to either inject a damp proof course, or pull the plaster off, seal it and replaster. It's nothing serious apparently, would just be good to get it seen to.  Cheers Share this post Link to post Share on other sites Share this content via...
