Hot water pipes and cracked plaster

Posted by Sam Crosby, on Mon 18 Nov 2013 08:06pm

Hi We had some work done less than a year ago, involved new central heating pipes being run through a wall and new plastering over it. This plaster is cracking and i Can feel the heat through it when the heating is on. Is it the heat causing the cracking? I am assuming the workmen didnt lag the pipes. How involved would it be to correct?

First thing to try is fill all cracks with decor fill. Sand and repaint. If cracks still appear then the only alternative is too caredully knock it all out slip a foam insulating sleave over the pipe.. Plaster an paint

The heat will be causing the cracking. Did you allow the plaster to fully dry before turning radiator on?

It sounds as if the plaster has dried too fast around the pipes any good plasterer from rated people will come out and have a look and give u a free quote for the work.this is not a big job there are also other causes it could just be badly done no tapes or pva you haven't mentioned if it's a brick wall or stud wall

Hi Sam Problem is a heat. Pipes should be insulated if boxed in by plasterboard and skimmed over. You can sand and fill crackes with polyfiller. But I would suggest to insulate pipe first as this problem can occur in near future. I hope this can help Best regards Rafal
