I had aluminium windows & doors fitted recently and the fitters left sizeable gaps between the window frame and the wood frame. They stapled some rubber strips and just left it like that. I've asked the fitters what I should but they say it's up to the builder, the builder says it's up to the fitters. Anyway, I obviously can't leave the wooden frame exposed so is it ok to just pull the rubber strips of & cement over?

The detailing looks poorly thought out. Why is there timber present? Is it a timber frame structure? If so, then the cladding or the cladding accessories/trims will deal with it?
Take a piccie from further back please
 
A couple more pics. The door & window was set in an existing brick building, but they built a wooden frame in the openings and installed the doors and window within those frames. I was going to put a breather membrane over the wall, then battens and wooden cladding. When I asked the builder what I should do about the exposed wooden frame. I got a "dunno mate, my job is done here". Obviously I'm not that impressed.

Is that just a one brick wide pillar between the frames? :oops:
The timber uprights are helping structurally by the looks of things. If it's being clad, then it down to the trims and clad returns, to finish up to the frames

Yes - engineered bricks done to SE's specs.
I guess the wooden frame needs to be sealed from the elements. It's too flush with the waal to use filler so can I just skim with mortar from the edge of the alu frame to the edge of the brick?
 
Why's the wood there? Did someone bugger up measuring and need to pack it out? If you skim with mortar it will crack and fall off.

If you want an airtight seal then perhaps UPVC trim, sealed against the frame and wall? Then you'd need to pack the battens out from the brickwork by the same thickness as the trim so they overlap it.

I don't understand the concept though!
 
I've asked the builder to come back and sort it, although I don't know how.
It's taking longer to sort the snagging than it did to build the extension.

I take that back, having seen those two bits of batten fitted in there.

Did you employ a builder or a bricklayer? I don't understand who is meant to be doing the cladding? :confused:
 
I employed a "reputable" builder and drawings & SE specs were all provided. I'm reasonably handy so am doing the horizontal wooden cladding myself. God only knows why they had to pack the doors & windows - I've gave them the measurements well in advance. Anyway, what it done is done. Before I put the vertical battens for the horizontal wooden cladding this issue has to be sorted but I don't know how. There have been all sorts of problems with the builders so I need to keep an eye on everything they do. This is why I'm on here asking for some advice so I can pre-arm myself with as much info as possible and make sure they do a proper job.
 
I'd want to have a seal of some sort between the brickwork and window frame. You'd also have a cosmetic sealing bead between the timber and window frame, but this will never be airtight.

You'd end up with a cold edge of the window frame if you cladded as-is, so would get condensation issues.
