Quote for triple glazing - too good to be true?

OneTime

Hi,

I've just had a quote to get triple glazing installed in my flat, from a company in East Kilbride called Advanced Group/Advanced Conservatories.

This is for a large sitting room window, mid-sized bedroom and kitchen windows and small bathroom window. It was £1600.

I have a relative who used the company and thought they were fgood, and another who used an alternate company (who double glazed his similar flat for about £1300 more) who showed newspaper clippings apparantley relating bad experiences with the one I've just been quoted by.

I can't find any info or reviews of them online. They advertise a full front page on the Glaswegian local paper in that means anything to anyone.

I am tempted but thought I'd ask here for info first.

thanks,

gubar
