Best way for (small) repairs on conservatory?

[chris1982]

Hi,
We just moved into a new house and have for the first time ever a conservatory, so I'd be grateful for advise on how to fix a series of smaller problems on it.
It doesn't leak (yet), but there is a draft around some edges and some black mould. I think there is a series of potential problems.
1. From the inside, I've noticed that some of the UPVC boards are bulging (photo 1). Is there a way to remedy or just fill the gap?
2. On the outside, I see that the fascia is coming off from its internal part (photo 2). I also think that the fascia and the glass top aren't sealed. Is that normal?
3. There is a strip of lead on the glass panes that is perished (again photo 2) What is the purpose of that lead strip? If it's important, I think I will run some flashband.
4. On the side, the bottom bit of the bargeboard is falling off (photo 3). Can I just glue this back with some silicone and/or expanding foam?
5. A short section of silicone along the roof profiles is gone. Obviously I want to re-do it, but access is difficult. Would the conservatory be strong enough for me lean on with my upper body?
Any thoughts and recommendations would be very helpful, as I got no experience with conservatories at all.

Anyone? Obviously I'd appreciate answers to any of the issues (you don't need to ramble on alll points, though you could if you want to!).
In particular, what do I do about the bulging UPVC boards?

Basically, fix stuff back the way it was. It does not really need writing about, and its nothing to worry about doing

Use suitable silicone or polymer mastic and add some suitable screws to keep things in place if need be.

Replace lead with lead or lead replacement material, not sticky black bitumen staining flashband
