Advice on Damp problems – are these damp specialists trying to make a quick buck?Make Text Bigger
To give you some background, I own a terraced property built 1888 which was later fitted with a dpc (drilled into brick) but I’m not sure how long ago this was. We refurbished the property 4 years ago, having all external walls re pointed and painted, we hooked off old damp plaster, allowed an industrial dehumidifier to dry out the walls before having re plastered etc.
Damp under bay window:
There are damp patches appearing under the bay window, I’m not sure if the dpc has failed here, but it looks like the tenant has had a virgin box installed that they no longer use. I have complained to virgin media that I believe the installation has caused the damp in the wall and this is under review. Damp specialists have advised me to pay to have an injected dpc under bay window but what are your thoughts??
Damp on rear window corner & lower internal partition wall:
A damp patch has appeared in the corner of the window, which looks like it moves down to the corner. Damp specialist also suggested having this injected dpc under the window and along, however it seems to me like that isnt going to solve the problem as damp starts heigh up.
Has the chimney breast separating the dining room to a small kitchen, the wall is extremely thick and is showing damp patches on the wall which rises higher than rising damp. We capped off the chimney and pointed the top to stop water from getting in so this water may just be trapped in the wall. The other wall in the kitchen, around the window white salts are appearing and this wall is damp also with crumbling plaster, the external wall is rendered so I’m not sure if the rendered external wall is causing a problem?
Damp specalist advised to have this dpc injected from the outside, to have kitchen taken out, plaster hacked off and replaced, however i dont think that would solve the penetrating damp (the kitchen walls are solid)
I’ve had a national damp specialist out but I’m unsure weather they are quoting unnecessary work. My issue is that I want to tackle the exact causes and then replace plaster etc so that it doesnt come back. It seems like the damp specialists are just plastering over wet walls and there is no guarantee that it will not come back.
Would anyone recommended having a building defect damp survey completed by an RICS member? If so, if their recommendations did not rectify the damp in the property would they be liable to fix? It looks like I am going to be paying out a few thousand pounds to try and fix this problem, I want to make sure it works.
