Glazing Failure

I'm afraid this is all rather mundane; however, a large bedroom window has been in a state of translucence since the double-glazed unit began to fail a few years ago. I've been meaning to get it replaced for a long time.

Six days ago I accidentally cracked a pane of mirror-glass on the bathroom cabinet, so I've received a quotation from a local glazier for both jobs - replacement of two panes of mirror-glass and the window - for £198 plus VAT.

I given them the Green Light. They estimate completion by the end of the week.
