Questions from Carmarthen
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
My old lantern leaks. Is it the lantern or the roof?
Often the roof or kerb detailing. A survey or close inspection will tell. If the lantern is the problem, replacing it is usually better value than repairing old polycarbonate.
Do I need planning permission for a roof lantern in Carmarthen?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
Can you fit a roof lantern in Carmarthen?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
