Plumbing Questions? Ask a Plumber for Answers ASAP
Hello and welcome to JustAnswer! My name is***** a technician with over 10 years of experience, and I'll be assisting you today. Sorry to hear your having issues, please stand by while I look into the problem for you, this is not an immediate service however I will try and respond as soon as possible.
Doesn't sound like the DPC if its that low down and effecting the floor. In reality I would get some samples taken of the brick to show there is rising damp before looking at chemically treating the DPC. The DPC should have also been checked as part of the survey for the property so worth going back to the surveyor to see what observations they had.
May also be worth getting an inspection camera fitted in the void to see if you have bridging between the outer and inner skin of the brick, as it does sound strange the issue is localised.
Have a great day, there is no need to reply back, however should you need further assistance please do come back to me.
