We’ve had quotes for both. 1900s house, the windows are a big feature of the house.
the cheapest was bog standard upvc…but lose all character like the curved window supports.
more expensive where the wooden (still solid) surrounds would be kept and upvc sashes put in.
most expensive same but hardwood sashes put in.
the last one would retain the character of the house.
would hardwood double glazing put you off a house?
