Just thrown the 2nd double glazing salesman out.
I am looking for recommendations of local firms who won't come round and talk shite at you for an hour, make up 3 different prices and then try to get you to sign there and then. 
Was looking at Invision windows. Anyone heard of them?
Or Edinburgh glass and glazing?
Price is important but not as important as quality, good workmanship and above all not pressure sales.
Aby recommendations or firms to avoid?
