Refitting a non structural piece of trim (see pics)

[stuartb3502]

OUr house has patio doors. Above them the builder created a brick arch feature. The gap between the lintel and the arch has a wooden trim piece. I should say "had". I went to repaint it today and realised it felt a bit loose. It was actually a lot loose and I just lifted it away and out.

What's the best way to re-fix? I hope you can see in the pictures that the void has DPM some broken tile pieces and then mortar. I wonder whether the wood was originally just pushed into mortar? There are a couple of screws standing vertically may be from where we had bifolds fitted last year.

I'm guessing a construction adhesive may be a better bet than what was done before. I don't have much experience with those. I have Gorilla Glue and No More Nails, but can get whatever is better/best. I wondered about filling gaps first. If I did this with mortar, I need to ensure that I put the right amount. Would test fitting of the wood whilst mortar is wet be sufficient to achieve that?

This type of stuff is new to me, so don't worry about tips including the basics Thanks,

Foam all voids and fit Uvpc to replace timber , then seal edges.

Thanks for taking the time to reply. Any ideas where I might be able to source a uPVC parcel or is it just a case of buying some sheet and cutting to size?

Thanks - that could work. The existing piece is slightly smaller so could cut one piece to shape. The existing one is about 80 mm thick (two pieces of timber glued and screwed). Good job it didn't fall out on someone's head. So fill the gap with foam, then adhesive to fix this on to foam?

Yes,I completely agree with Foxhole. Foam it up then once set completely cut it back, set back from the front of the bricks. Then glue trim to foam and seal around with silicon. Mask the bricks and frame with tape before you start as excess foam could spoil it otherwise.

Might get away with foaming the whole thing then sticking the new piece in, if you can hold it from pushing out as it sets

Thanks everyone.

Get a peice of 18mm ply, cut to size to fit the gap, then glue the upvc onto the ply and cut it out and fit into place.

Push into place and silicone around the edge.
