  • I know a lot about building and insulation. The most likely cause of this is pre-existing damp that was just exasperated by the insulation making it warm on top of the damp.

    If there is any sign of “rising damp” the modern way of dealing with it is by installing a layer of DryRods, however if the insulation was installed during a particularly dry period there might not have been evidence of a pre-existing problem.

    Other than that possibility it could be an unrelated pipe leak, physical damage to the insulation and render, or an issue with the guttering.

    Finally cold-bridging where a portion of the envelope of the house is uninsulated and forms condensation, this is pretty much the only issue which could be a mistake on behalf of installer, but even then it should be obvious and made worse by failing to open windows or turn on extractors when showering, drying washing or cooking.

    Any of this information could have been in the article, it’s absence is suspicious. Whatever the reason the first thing you need to do is let the contractor investigate.


  • It sounds like the company is offering to come back and fix whatever problem is causing the damp but the homeowner is refusing to let them fix it. Sounds like they’re just idiots.

    The article doesn’t say what installation standards are not being adhered to. It’s not rocket science, you take insulation boards, you glue or screw or both to the house and you mesh ad render over the top. It sounds like whoever wrote this didn’t do much investigation.
