As a competent DIYer, I found the instructions good and the bifold doors easy to install. They look great and the communication around delivery was very good. The only issue I had was when I removed the masking tape, post plastering, from the frame. Despite having sealed the frame, the tape pulled off some of the veneer. I don’t think I was too aggressive and the tape had been on less than 6 hours, so very disappointed and surprised this would happen. Real shame but I can cover most of the damage with an architrave. Hopefully the veneer on the outside is adhered better, I am going to give it an extra coat of protection just in case.
