Is this rising damp ?!

Interesting. When I bought my house it had a new dpc and had been replastered. About 3 years ago I started to see rising damp but the guarantee is worthless. What is the treatment for this nowadays as dpcs don't seem to be the thing now as they were in the 80s. Will I need to treat and replaster or are their other options? Thanks

Did you have a silicone injection (not being personal :heyhey:)..?

Or was it a 'real' damp course - this is possible, but an unlikely retrofit.

If it was silicone, it could be that it could do with doing again, maybe?

Modern building techniques don't work with older houses.
Older houses also expected to have open fires running, or at least boilers getting their air from inside the house, and draughty windows and doors, pulling a much higher air-change rate than you'll get today, especially with balanced flue heating and better fitting windows and doors.

I open my windows most days. As a thread resurrector said the other day, lowering the relative humidity actually makes the air feel warmer even if it isn't.

The previous occupants of my house tanked it inside. Of course the cement cracks over time and moisture seeps through. We have lime plastered walls where this has happened to allow it to breathe.

It had something injected as I have the round holes.. What's the treatment nowadays?

That'll be a silicone job, I would suspect. I imagine that it still goes on now, but I haven't seen anybody doing it for ages - of course, there are no new houses that should 'need' it.

I'm not sure if there's a new treatment that has superseded it, or if there are even many people left that would do it. The market would have been fairly well saturated by the end of the last century.

It seems 'possible' that its effectiveness could reduce over time, plus the(probably greater) effect of the lack of dispersing ventilation.
