In November 2022, Mrs Khatun had her house insulated under a government scheme known as ECO 4. It is designed to help low-income households make their homes warmer and cut their energy bills. Insulation boards are fixed to the exterior brickwork of a house and then coated in render.
More than three million homes in the UK have had insulation fitted under government ECO schemes, which are paid for by the energy companies, with the cost passed on to all consumers through their energy bills.
The BBC revealed earlier this year that hundreds of thousands of these homes could have insulation that wasn’t installed to the required standard. Within months of Mrs Khatun getting her insulation fitted, it became clear that this was the case in her house. A surveyor’s report shows how rainwater penetrated the house leading to the damp, mould and dry rot.
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.
I agree but I can see why someone might not want to invite the people they feel ruined their home back to have another go.
I agree, but then articles like this are the reason these people are so annoyed at the installers, they make it sound like there are mysterious procedures and practices which are not being followed, while failing to detail any of them and making the problem worse.
Anyone reading this will only ever come to the conclusion that they had a bad installer and won’t want their help, all while their house is turning into a stroganoff.
