Double glazing - North east London / Essex borders

[ch1a]

Can anyone recommend a good local firm in this area? We are in South Chingford and want to do all Windows and doors in our house. After an extortionate initial quote from Everest I need to find someone cheaper and reliable with a good product. Thanks in advance...

I can recommend chase windows in Enfield - they did our last house and are about to do our current one - I think they cover London so I'm sure they'd go to south chingford.

This time round we got a comparison quote from Anglian as they had done a few houses in our area recently, but the quote was laughable and was 2.5 times more than the chase price!
