[Closed] How much for:Injecting a DPC

I bought my current Victorial brick built terraced 2 years ago and since then I`ve noticed damp to one corner of my lounge.

It has evidence of the dpc having been injected before, with the tell tale holes along the brick course but it definitely looks as though it needs to be redone.

Any idea of cost?

Sure it's really rising damp and not water ingress from leaking drain, gutter, shower tray etc?

This.

Best to make sure it is what you think it is before proceeding.

If it's still there after injection then the injections surely not worked? I'd get a local brickie in to replace it with a new DPC if possible. If not then just get on to ebay and buy it yourself some wykamol ultracure or similar.

I've got a similar aged cottage with similar problems and have done a bit of both to keep costs down. injection's easy to do yourself

If it's a corner there's a good chance it's condensation. Corners are colder due to more outside surface area to lose heat. Insulation may be the answer.

Hi Pretty certain its not condensation.It only affects the bottom 150mm of the wall and plaster is wringing wet.

Its not near any plumbing or drain either.

Will look at Wykamol.

+1 what every one else has said to check first though

our place had combinations of all sorts from genuinely damp bits of walls through to covered up vent bricks
-soil from neglect
-roof slates put there on purpose to stop drafts I assume
-a concrete path against a wall over the DPC and vent brick
and therefore rotten floor timbers

and that's just the start 👿 we love it though

btw if the damp is up there and that bad then really the plaster needs to come off and have it re done with some additives too. the injection on it's own won't do it apparently.

and if you're going to that effort and it 100% is damp and nothing else then IMHO you should get the DPC replaced at least on the internal walls.

My brickie charged about £300ish I think it was for replacing about 10 meters with a plastic DPC

Injected DPC is a waste of money

no it looks like the previous owner was sold snake oil and youll probably find that the damp is coming from else where.
