I think by the time you try and fix the mirror you would be better off just taking it down. Mind you it will probably mean fixing the Sheetrock behind. But it will be a big improvement. If you do remove mirrors , masking tape the glass like crazy and wear protective goggles and gloves.

I agree, the mirrors are better off going, and it will look so much better without them. Think of all the wall space you will gain, and the all the glass cleaner you don't need to use to get rid of finger prints :-).

Clear silicone. I seen a wall like this curtain up to ceiling & a window view open. It looked nice & brought light in.

If you just can't remove the mirror and don't want to see it at all, cover it with floor to ceiling curtains. I love fabric walls and you'll only "loose" a couple of inches of space. I've purchased track style curtain rods that attach to the ceiling at Ikea and they also have extra-long drapes at a good price. In one room I even used flat bed sheets that I sewed into curtains on a ceiling mounted track.

You could just glue thin bits of timber onto it, the black wrought iron looking one you could glue thin strips of rubber.

Art looks good, don't know about the crown, decals might be effective, heaps of decals on eBay and etsy, hope these helped

I said what Ms Hayes said. What have you decided?

Thanks for the great ideas. Haven't done anything to it yet but I really like the idea of gluing trim to cover the seams and frame it out.

Joyce, I am going through the same thing right now. Dining room in a 1978 house with one mirrored wall. My husband wants to remove them but the room is small and I'd like to update them in a cool way. Thinking of the wood framing too but would need low profile pieces. Also thinking of antiquing the glass or finding artistic but classic decal/faux etching of some sort. No solution just yet. If you do something, I'd love to see your photos! Much luck to you!
