I bought an XL 'oak' door many years ago, what a piece of rubbish.
Failed visually within 8 weeks despite being treated as per recommendations, XL refused any warranty claim and said it needed to be protected by a porch.

XL Joinery, what a joke.
Don't buy internal doors from XL Joinery, the quality is really poor and the aftercare service is even worse. I bought 21 internal doors and over a year 15 have warped, XL are not interested as the doors were not painted behind the hinges!
DO NOT BUY DOORS FROM XL JOINERY
