I think it is the trims that had swelled and not the doors?If you search on the net, there are lots of companies that supply veneers, and you might find your particular type of ash from one of them. But replacement doors from and old cararavan could be tge best option.
Thanks for your reply. The leak is currently being repaired we are just trying to sort these out before refitting them. ☺️I would suggest getting the leak repaired before attempting anything else. There are a number of places that can recover the veneer depending where you are located.
Yes the doors are absolutely fine thankfully but they are solid wood. It's the veneered trims that took the battering.I think it is the trims that had swelled and not the doors?
