Can you make a mirror ever so slightly smaller?

[Wigeon]

We have just had a circular bit of mirrored glass cut for a circular window in our porch to cover the window with. However, the window is in a little niche and it turns out the niche is ever so slightly smaller than the window (think 1 or 2 mm smaller), so the bit of glass doesn't fit in.

Is it possible for a couple of millimetres to be shaved off the mirror, all the way round the circle?

Obviously I could ask the shop who supplied it, but they have messed us about so much (in relation to the new front door they've fitted, and supplying this blimming bit of mirror) that I'd rather only ask them once I know it's possible!

Thanks in advance.

no.

Not easily, no. Any chance you can make the niche a little bigger?

You can't cut it smaller, but you can grind it smaller. Find a glass company with an edge polisher, they should be able to do it for you.

That's assuming it is actual mirror, and not toughened mirrored glass or something.

Have they made it to the correct spec though? if not, take it back and tell them that it is the wrong size.

I had a new piece of glass fitted to a barometer by a glazier, but they drilled the wrong size hole in the centre so none of the hands worked. I refused to accept it and they had to do it again.

they will be able to do it, so ask them

Thank you for the advice.

The niche has a thick metal rim, and then is brick, so hard to make that smaller.

I think a bit of grinding smaller might work - it's really almost there. Not sure whether it's actual mirror (probably) or toughened glass (probably not).

Annoyingly, I - not they - measured the window inside the niche and rang them with the measurement, so they did cut it to that size (actually 2mm smaller as agreed).

It was only me who measured it this time because they forgot to deliver the mirror with the new door, and then when I finally got round to popping into their shop to pick it up this week, they claimed that they throw out all uncollected stock after 3 months (which they never told me was the case, and never rang to warn me), and would have to cut another one! Hence me measuring it.

Frankly I don't believe they ever cut the original bit of mirror, let alone threw it out, since I went back almost exactly 3 months after the door was fitted, so they'd surely remember throwing it out earlier this week .

(If anyone is looking for a door company in Watford, I can heartily NOT recommend these people!)

I will pluck up the courage to ring them about it and see if grinding is possible! This is about the zillionth issue we've had with them (mostly over the front door) and I was looking forward to never having to deal with them ever again.
