I bought a short length of square edged window board, which arrived in very quick time. However when I opened the package up the board was of very poor quality and was definitely not square edged, the front lip was bending inwards by about 25 degrees. It would not match up with the very square end caps which I purchased with it. I sent the company some photographs by email and rang them. The young lady on the phone was very helpful and agreed that it was not square, She told me it may have been a bad batch that got through and that she would arrange a replacement to be sent to me. The replacement arrived, once again very quickly, but alas it was not a great deal better. The quality of this window board is frankly awful and it is far from being square edged. I can not use this in my home and both pieces are going in the skip, the only place for them as they are rubbish. I emailed the company to tell them this and so far I have had no response. Sums them up to me really. I have put this down to experience and basically thrown my £32 away. I will source a decent quality window board elsewhere. I wouldn't touch Tradeline UPVC with a bargepole. You have been warned.
