What would roughly be the cost of replacing the sealed .double glazed clear glass unit of size 950mm by 770mm. I have had a quote of Â£100 + VAT. Is this reasonable. Are all sealed units the same or would the quality differ
How old are the windows?If they were put in in the last four years or so they may be argon filled?If so and you have had a quote like for like then that is quite reasonable,however if they are standard double glazed units
then this is quite expensive!Are they ali or plastic windows?
