Damp around newly installed composite door frame

[House2009]

Please can someone help? The day after we had a new composite door installed, having removed a timber door & frame, water has appeared all around the internal plaster wall. The silicone seals are sound all around the external frame and there is no condensation on the door or in the room.

The water is along the top and both sides. It looks like something is occurring within the frame and the wall. There are no pipes or gutters nearby and the problem has only happened since installation.

The water is getting progressively worse day by day regardless of the weather. The previous timber door never presented this problem. There was a damp proof membrane attached all around the previous timber frame which the installer had to cut to remove the old frame but left the remains in situ as it was also attached to the wall.

The installer is coming back but I was hoping to get some ideas. We have used him for years and he is Fensa registered. We've never encountered this problem before. He thinks it may be condensation forming in the frame area which is then weeping onto the plaster. Any ideas please would be welcome. Thanks

I have posted pictures of the problem in my album 'Door' on my profile. You can see the difference from 2 days to 2 weeks in the pics.

Is there any accumulation of water on the frame or the little trims he used around the edge?

Hi, no none whatsoever. The frame and all the little trims are completely dry. The wetness on the plaster appears to be seeping through from behind the little internal trims.

is it definately water? once i sealed up to some paintwork and something like this happened, it wasnt water damage, we just put it down to the sealant reacting. (it wasnt water because it was in an office)

Is that wall paper to the reveal?
Could be the adhesive slowly failing where it meets smear of sealant underneath.?

No it's definitely painted plasterboard. No wallpaper here but thanks for your suggestion.

the one im talking about was painted plaster

S60tsy I think you are right. There is no damp. We checked this morning with a pronged device & it registered no damp at all. It looks like the clear silicone used to stick the trims to the wall has had a reaction & is producing a grease that's tracking across the wall.

Once we got the trims off the plasterboard underneath the paint layer is completely dry as is the door frame so thankfully it's not water ingress or condensation.

Planning on painting the area with an oil based undercoat to seal it & then putting on new trims with a brand new tube of sealant. How did you resolve your situation? Many thanks

It was only in a back office so it's still the same

Lol did it get any worse or did it eventually stop getting bigger?

 

[s60tsy]

It stopped about at about an inch
