Hi, I am looking at replacing 4 patio doors with JELD WEN Clifton product - the quality and guarantees look really good, the product comes supplied ready to drop in in frames, and they have to be wooden products due to the nature of our building. I have a reliable builder who I'm going to ask to do the job. Does anyone have comments on this product? It can't be worse than the rotting doors we have at the moment. Are there better products? I'm avoiding bespoke local firms because the last quote I got was quite high, and using standard JELD WEN sizes is cheaper.
