Thanks - we have been looking at A1 and it is good to have a recommendation that their service is good.
We have been told by a builder friend (who is too busy at the moment to do the job for us) that trying to renovate the existing one is a huge job and would cost us nearly as much as a new one. We trust him to give us a fair judgement - and he would not be doing the job, so has no vested interest in giving us wrong advice. I can see that the uprights are rotten.
Thanks also for the Taylors recommendation - I will look those up.
Lest we forget what we have just lost ....
