We're in the process of selling our house, we've had a letter from the solicitor asking for the certificates for windows that were replaced in 2005 (2 windows others done before we bought it - before 2002) and the back door that we replaced 2 years ago.
We can get the back door one, but when I search the FENSA website the windows don't appear and the company who fitted them have gone bust. What do we do? Is this going to cause a massive problem?
