Conservatory temporary fix

[tonkski]

I have a glass-fronted passageway with a heavy tiled roof running down the side of my house. It’s not really a conservatory but that’s the closest word I could think of. Single glazed, old, presumably diy construction. The timber running along the top of the dwarf wall is starting to rot, as is the base of the load bearing uprights. I had planned to replace bits of rotten timber and use the Ronseal stuff, but the whole thing is in a sorry state and needs replacing when time and funds allow. To keep it standing until then I need to do something temporary. I was thinking of attaching (thru-bolts maybe) a vertical post to the existing uprights, with the base resting on the dwarf wall. My questions are: How do I fix the post in place so that it is taking some weight? There has obviously been moisture about. Is there any way to make sure the base of the new upright doesn’t start to absorb water and rot? I’ve taken a photo to try and clarify my ramblings. Thanks all.

Set your new timber on something impervious to moisture, engineering brick, tile etc.

Thanks. That sound simple enough. The top of the wall is irregular - could I bed a tile in thick mortar and put the post on that?

You can also seal the end grain with a product. No experience, but for example:

(I would probably both seal and install something damp-proof, just in case)

Car body filler or poyester resins for laying up glass fibre work well in this application.

You could use acrow props. Don't look great but work fine.

Never works at preventing rot though. I presume the coldness causes condensation & thus rot.

Sounds like a sun room as opposed to a conservatory ?

Maybe two angled brackets, possibly galvanised at 90 degrees so they take the weight. Unfortunately, the only way I can think of to make them take the weight is to remove the rotting bottoms of the uprights. Brian

Would that not upset all the glazing though? Brian

[tonkski]

Yes, sun room. Couldn’t think of the word.

[tonkski]

I think that would mean the horizontal timbers at the bottom taking some weight, and they’re unfortunately rotten too.

Thanks everyone for your ideas. I have some acrow props holding up the dodgiest areas as a very temporary fix. Getting some quotes for a proper solution this week.
