Hi we have a new build that we bought in feb, one of our snags was that the gloss painted woodwork was yellowed not White when we moved in. The site manager admitted it was indeed yellow and should be White so the painters were brought back to assess the problem. With them they brought the Crown supply manager and we discovered this was a country wide problem that some houses' paint was turning colour and others were not. The painter confirmed our house was completed paint wise in the last week of jan, we moved in in the 2nd week of Feb so it had yellowed in 2 weeks! The builder admitted this was wrong and the gloss was repainted. 2 weeks later it started to turn again and much worse than before- it positively glows yellow! We have gone back to Persimmon and they said it would be addressed again. After hearing nothing for weeks we contacted them again only to receive a letter stating that due to new regulations in paint recipe the colour fastness of the paint could no longer be guaranteed and that they consider reapplication to be a household maintenance issue and would not be helping further. We are outraged at this especially as they have already admitted it's wrong and tried to fix the problem once already! We understand that the cause of the yellowing is a mystery to them and the painters and that we are not alone in this problem but still the product they have used is unfit for purpose! Is there anyone with any advice on how we can take them on regarding this? We just anticipate such a struggle as we have other snags that they are being difficult over... Thanks!
