They say they don't subcontract, from the website:
http://www.snowdoniawindows.co.uk/
The secret of our success lies in our commitment to both quality and service, which is why we only use Snowdonia employed, experienced fitters, to install our products.
Also, from the website they say they manufacture all their products themselves, so according to that they told my Mum a **** and bull story about having the door not turn up on Tuesday, they are lying one way or another there.
It really is farcical, the door and panel frame were ordered over 8 weeks ago, they came on Tuesday to install, but told my old dear that the door had not come, so they fitted the frame and panel and blocked the doorway off with some temporary door thing, told her they'd return today (Wednesday) with the door she ordered and fit it, they came today and fitted the door but it has a fault on an interior panel from manufacturing that they say needs replacing, this is going to take 10 days to come (Strange, the website says otherwise...) she gives them the payment and they bugger off.
I visit my Mum to make sure she's OK and check the door, she had been told to phone me if there was any problems I live 15-25mins away, she was worried I'd kick off about the door not turning up when it was supposed to so she didn't phone, now I trusted these monkeys, any other firm without any sort of reputation and I would have been there watching, but my old dear is knocking on and she worries about her independence so I was happy there would be zero problems and let her have the feeling of independence by not turning up and taking over things for her.
The door does not fit the frame, there is a gap from the top of the door down to around halfway, the weather-seal is nowhere near, I can fit my huge fingers in the top gap. The door is very difficult to lock which I can only assume is also an alignment problem somewhere, there are various uPVC strips that look like decorative covers, one of these strips is pink, it looks like a manufacturing problem and stands out like a sore thumb, no idea how the fitters missed this as it is the full length of the door. Where they've fixed the frame to the brick looks like a child has been given a hammer drill to play with, just very shoddy workmanship and is not very solid at all.
