I live in Ashford and one of the double glazed units in the rear patio doors has blown it’s seal and condensation has got into it making it impossible to see through, as well as not looking very nice. Could you please give me a rough quote for a replacement double glazed window unit and fitting costs. The window measures approximately (estimated measuring from the inside). H- 1800mm W – 665mm D – 25mm The only markings I can make out on the inside of the glass window unit are – VG BS5713 KM37917, so I don’t know if that helps any. We are also looking to replace our UPVC front door so would like a quote for that also. If you require any further information please let me know. Many thanks
