Is there anyone on the Coast who does this?
Sometimes the honest answer is that the nearest is in Christchurch or Nelson, and the quote should say so with travel in it. NovaPay asks locally first and tells you when it has had to look further rather than quietly widening the search.
My window is broken now. What happens first?
Making it safe. Most glaziers will board or temporarily secure the opening the same day and return with the cut glass once it is measured and ordered, since panes are rarely stock items.
Why has my double glazing gone foggy?
The seal on the unit has failed and moisture is inside. Cleaning will not fix it; the sealed unit itself is replaced, and usually only that unit rather than the whole window.
Can I claim it on insurance?
Often yes, and glaziers deal with insurers constantly. Say it is a claim in your request so the quote comes back in a form your insurer will accept.
Can double glazing be retrofitted?
Into many existing frames, yes, which is far cheaper than replacing joinery. Whether it suits depends on the frames you have, so it needs a look rather than a phone answer.
