HC Deb 10 March 1970 vol 797 c1110
36. Mr. Frank Allaun

asked the Minister of Public Building and Works if he will undertake a survey of new houses and flats where serious dampness has arisen; and if he will introduce legislation to make the building firms concerned financially responsible for subsequent insulation or correction.

Mr. Loughlin

I wish to apologise for the length of the reply.

The Department has carried out a number of surveys to establish the causes of dampness in new houses and flats and I do not consider that further surveys would provide any new information on this subject. The surveys have shown that the causes of dampness are often complex involving questions of design, construction and the way occupants use their house or flat. In the circumstances a greater awareness of the technical and social factors is likely to prove more beneficial than additional legislation.

Mr. Allaun

After all this trouble, is it not culpable that the designs of many new houses which are being constructed at the moment are still causing serious and avoidable condensation? Will the Minister consider making a requirement to see that available knowledge on this subject is utilised?

Mr. Loughlin

We are trying to examine the precise causes. There is some doubt whether the usage of the house is not a greater contributory factor than some of the design faults. I mentioned in an earlier reply that the new design guide will be out shortly. I will send a copy to my hon. Friend.
