Nothing. I have since discovered some condensation on the 1st floor internal wall which might be part of the problem?

Damp patch on inside wall.

I will just try to dry out the inside wall now the render has been patched up. Hopefully no more water ingress.

Thanks jayc89. Yes that's what I thought . Trapping the moisture in is my worry. Cant really replace the external render so I will try and dry the room out from the inside over summer. I will remove the internal plaster so the bricks can breathe.

This has appeared over the last couple of months on a North facing gable internal wall. I have found a small area of damage to the cement render on the external wall so assume this is where the moisture is coming in from. The wall is solid brick with gypsum plaster internally. Should I repair the render now to prevent a further ingress of water or will that seal the existing moisture in? I am worried with all the rain we have been experiencing that if I don't do something soon the problem may get worse. Any advice would be much appreciated.

Thanks for the heads-up. There is internal lime plaster on one side of the building, however there is cement external render. Would this keep the wall airtight? I don't care about meeting any targets or building regs. I just want a warmer home and I am sure any future purchaser would be happy there is some insulation in such an old property. It will be me fitting the wall insulation, I just want to make sure I achieve a decent improvement and it not be a waste of money.

Yes there maybe a very narrow cavity behind the breezeblocks on one side? Thanks for the advice.

Yes that's what I thought thanks. Upstairs that extra 12mm will be very helpful. I presume they will be fitted to wooden batons?

Ok thanks everyone for your invaluable advice. It seems fitting the house out with the ultra-thin vacuum blanket stuff could be prohibitively expensive. The advice to fit 25mm of sheet insulation would be affordable. If this greatly improves the house then I will be very happy. Would this just dot and dab over the existing plaster or would I need to go back to bare brick please? Many thanks

Hi all I have an old solid wall brick cottage. On one side an internal breezeblock skin has been built and the exterior walls have all been cement rendered. The property is cool in summer and freezing in winter. I am tight on space as externally the building is only 4m wide. Whilst I appreciate external insulation would be better, I am in a conservation area and I may need to alter the roof to accommodate this. Is there a good, high performance thin internal insulation which would be suitable please? I have seen Kingspan Optim -R advertised an wondered if it was any good? Cheers

ok thanks guys. I will have a look at the EWI options. Can this be done by a DIYer?

Thanks. Unfortunately, the render is well and truly stuck to the brickwork. If it was easy to remove, I would be more than happy to remove it.

Hi all I have an old brick cottage which unfortunately was unsympathetically renovated in the 1960's. The external walls have been cement rendered and an internal breeze block skin has been built to one side of the property to support replacement ceiling joists. In winter the house is extremely cold, and the long narrow style means that using thick internal insulation isn't an option. The house is in a conservation area, so the local authority is not keen on external insulation being used. I have seen foil type internal insulation advertised which can compress to 10mm which would work space wise but I really don't know if it will perform well enough. Any advice would be gratefully received. Many thanks

Hi all I want to replace my current single panel radiator in my lounge to double convector as the room does not get warm enough. The current rad is 3000mm and I have purchased a couple of 1400mm rad's to replace it. I though about joining them together but not sure if it will be better to alter the pipework and fit them in-line with separate controls for each? Any advice would be most welcome. Many thanks
