As part of the house redo a corner of the window cracked as per the photo, it's about 15mm x 45mm. Multiple tradespeople worked in that area so I'm not trying to assign blame, just sort out whether it's worth getting the pane replaced. We have to get the rubber seal around the outside replaced so there'll be a glazier here anyway, however we're also getting UV-blocking foil put on and the foil guy said he can just cover it with foil to try and mitigate it.

Does anyone have any thoughts on the value/necessity of getting the glass replaced? Since there'll be a glazier here anyway to replace the seal the cost is marginal beyond that of the replacement pane (a standard size approx.110x70, best estimate I could get for 1m2 generic float glass is about $100), and if we don't address it now and it needs fixing in the future it'll include the cost of getting the foil replaced. OTOH if it remains relatively weathertight and the foil will cover it, is it worth the expense?

Do it once, do it right.

Lazy is such an ugly word, I prefer to call it selective participation

If you're anything like me, not doing it properly now will mean:

- your eye will be drawn to it every time to enter the room
- you will go on - at length - to your significant other how much it annoys you and how you wished you had done it right the first time
- upon exiting the room, you will immediately forget about it
- you will repeat above steps continuously over the course of several years
- you will decide to sell the house so finally get around to sorting it
- you will enjoy how good it looks every time you enter the room
- you will go on - at length - to your significant other how much better it looks and how much you wish you had sorted it years ago
- you will repeat the above two steps continuously over the course of the week you have before settlement
- you will immediately commence the cycle again in your new residence

I am with AMI and I have glass cover with no excess, I wish I had known that before I had replaced two broken glass pains in different doors due to different wind gusts.

Check your insurance policy, you might be in luck.

… or when a deliberate pun is superbly subtle.

Sometimes I just sit and think. Other times I just sit.

If you have glass cover on contents it's free and does not count as a claim.
It's hard to "blame a contractor" unless you had photos before work started. Corner cracks are usually due to glass being tight in frame. Or glass rubbing on frame with weather changes.
When glass is out "seal the mitres" as windows of an age will start to leak from the mitres.
Another option (we did this) retrofit double glazing it was not to badly priced. Or if budget allows replace window frame. If you are in Wellington I can give you a name.

Just checked, there's a $250 excess so not really worth it, but thanks for the info. As it happens I've got before and after photos, but I don't want to get into finger-pointing, s**t happens and since the glazier has to come out anyway to replace the seal it's no biggie.

So the glass has been replaced... but not the seal. Glazier said the seals are to hold the glass in place, not to keep out water, and what was missing was a drainage hole in the frame to let it out once it'd got in. I would have thought a drainage hole doesn't matter if water can't get in in the first place, but there you go. In any case I've siliconed up the gaps because prevention/cure, but now I'm worried that the silicone may end up impeding water flow inside the alu joinery, sigh. Here's a known-good window (with a gap in the seal, now siliconed):

Here's the problem window, with seal gap and a drainage hole provided by the builders:

Finally, a second lower-down hole further along that they drilled to try and find where the water was going:

Despite being only a few mm lower down than the one in the corner, it allows access down into a hollow space inside the vertical part of the frame, so I've siliconed that along with the corner gaps in the seal using as little silicone as possible for the reason given above.

A search of various BRANZ docs isn't finding anything like the joinery used here (mid-70s house) so I'm not sure what I'm dealing with inside the frame, can anyone see any problems with this?
