There may be nothing you can do. Was the work done before 1995? Do you know who the contractor was?

If you have no sucess you may have no option than to simply remove it at your own expense. You may however not need to remove all, it depends on the extent of the problem. Good investigation work required by suitable specialist.

Ring me if you need to discuss further.

The answer is yes, its better to check now so that you can take appropriate action!!.

You could remove some bricks or use an optical endoscope which will initially be less destructive.

If the insulation is wet you may have to consider its removal, although you need to take specalist advice.

Where are you located?

Last year, the stream at the back flooded and the level of water around the house was higher than the damp proof course for about an hour.
We have not noticed any problems with damp, but have had a surveyer round who has indicated high levels of damp in certain areas.

I am concerned that the insulation will have got wet and with no air circulating, it will not have a chance to dry. What would you recommend? Should we remove bricks in the damp areas and see what is happening inside? If so, who should we get to do the work?

Many thanks.

Hi,
I have been in the insulation industry for 9 years. My job is to train the field surveyors to check each individual property to determine whether it is suitable for receiving cavity wall insulation.

If anyone is thinking of getting their homes insulated you should bear in mind the following:
Always go with a reputible, well established company.
Make sure that a complete thorough survey is undertaken (this should include a boroscope check and combustion vent check)
Ask what material they use, It must be superior quality (Knauf Supafil mineral fibre will not allow damp or cavity bridging to occur under proper conditions)
A good company will also colour match the mortar in the drill holes.
And make sure they are backed by a 25 year C.I.G.A. guarantee. This ensures that should anything happen you are covered.

There are many benefits in getting your home insulated, including saving money on energy bills, more comfortable living environment, reducing co2, reducing carbon footprint, improving energy rating (EPC)

13 motnhs later damp has appeared in the living room which is the pine end of the house house. This side of the house faces the prevailing wind and rain etc. The type of insulation used was the wool.

Since the damp appeared my father has removed bricks etc and found the cavity was full of debris and rubbish. This is despite the company saying they checked the cavity and it was deemed fine to proceed.

The company have offered to remove the insulation and meet all costs including decoration etc.

However some people including the local building inspector are saying that its not the insulation causing the damp and not to remove it as it is serving a purpose by being in there

what would you advise etc ?

i,m a brick layer , would just like to say to the people thinking of having cwi who live in modern houses ie 2001 and later, dont bother! the levals of insulation already in the walls should be more than good enougth already, cavity plus celotex cliped in place is as good as its going to get i would just put more loft insulation in.

as for the damp with cwi i would look at the materials the exposed outside walls are built from and how pourus
they are

i live on a 1960s street where 90% of the houses have now been done with no problems.
i am about to have my own property done. after years of cleaning and clearig cavities at work it does seem to go against the grain to fill them but im going to take the chance as the house is so cold compared to modern houses with high levals of insulation.
