Restoration & Refurbishment Question

Leaking walk-on rooflights - painted cast iron with small panes

We have a Georgian house with three walk on rooflights allowing light into our basement. They have always leaked but because we are redecorating we want them permanently fixed. The frame is cast iron (I would guess as they are rusted) with small, thick glass panes. There's about 16 panes per panel and the leak is from the panes.

I'm trying to work out who could fix this(possible more relevant to commercial glazing than residential?). I've tried searching but can't find this type of sky light. Looking for a specialist who's done this before.

Appreciate any advice.

Obviously it cant leak through the glass, so it must be the iron itself in such a bad state that water is now able to penetrate the iron via rust. The problem is once you mess with it another part may leak, so it sounds like you need it overhauling or replacing. Costly. Only cheap way I can think of is to use a liquid clear resin and paint the iron and putty glazing with it to try and seal it that way, without the need to replace or overhaul. Bit like clear nail varnish on your nails. Just try not to paint the glass itself. Definitely a specialist job though by sounds of it but i do not know any glazing specialists so its a restoration/renovation contractor you need.
