Four quick questions. Most quotes come back the same day.
Glazing in and beside a door is a safety glazing position under NZS 4223, so door glass goes back as toughened or laminated. Bifolds add a second issue: a run of four or six leaves is only as good as its alignment, and the whole set stops working when one hinge or roller lets go. Wellington decks take a lot of wind, which loads the top track harder than the manufacturer probably imagined.
Reglazing door panels
Panels are large and heavy, and the glass is toughened or laminated, which means it is made to order. Allow several days. Where a panel cannot be left we board it or fit temporary glazing.
On double glazed doors the whole sealed unit is replaced and not one pane, and the setting blocks are renewed so the new unit is not carrying load on its corner.
Bifolds that bind
A bifold hangs from a top track on rollers, with guides at the bottom. When one roller wears, that leaf drops, which puts the next hinge out of line, and the fault travels along the run. By the time it is reported, several parts are usually involved.
We set the whole run rather than fixing one leaf, because a bifold only works if every leaf is square to the next.
French doors and drop
French doors sag at the outer edge because the whole weight hangs off three hinges. Once they drop, the doors catch each other at the meeting stile and the lock stops throwing cleanly.
Replacing worn hinges and resetting the doors fixes it. Planing the meeting stile fixes it for a year and leaves a permanent gap.
Setting a run of doors, not one leaf
Why the fault travels
A bifold hangs from a top track on rollers with guides at the bottom. When one roller wears, that leaf drops, which throws the next hinge out of line, which loads the roller after it.
By the time it is reported there are usually three or four parts involved, which is why replacing the one obvious worn roller rarely fixes it.
French doors and the meeting stile
French doors sag at the outer edge because the whole weight hangs off three hinges. Once they drop, the doors catch each other in the middle and the lock stops throwing cleanly.
Replacing worn hinges and resetting both leaves fixes it. Planing the meeting stile fixes it for a year and leaves a permanent gap that whistles.

Bifold and French Door Glass in Wellington: common questions
How long does bifold door glass take?
Several days, because toughened and double glazed panels are made to order. We board or temporarily glaze in the meantime.
My bifold has started binding. Is it the track?
Usually a worn roller on one leaf, which throws the rest of the run out. We reset the whole set instead of one leaf.
My French doors catch in the middle. Can they be adjusted?
Yes, by replacing worn hinges and resetting them. Planing the meeting stile is a short term fix that leaves a gap.
