Replacing windows in high rise flat

[themeone]

I want to replace windows in a 9th and 10th floor maisonette. I've contacted two installers, one said they couldn't do it as they didn't have the required safety equipment for operating at height, and the other said it would need scaffolding.

I've had windows replaced in another property which was 3rd floor, and no scaffolding was used - they replaced them from the inside.

Is scaffolding required above a certain height, or does it come down to the preference of the installer?

This. They can be done from the inside but needs appropriate safety harnesses etc.

Usually the replacement of external elements of the building would be down to the freeholder/management company.
Have you checked your lease to see what you are allowed to change?

Yes I've got permission from the freeholder.

Are the windows going to be the same design as the old ones, any spandrel panels used anywhere, if not then PP may be required. I guess high rise flats could put companies off, scaffolding bumping the costs up beyond your budget or companies not wanting to fit from inside and dangle windows out 10 floors up, having to use a 'man safe' or harness which you need training for, then the logistics of getting the frames up there

And not forgetting the whole Grenfell thing, it could just put companies off

It would be a like for like replacement yes, but I don't know what a spandrel panel is so can't answer that.

I'm starting to get the feeling the job is a bit of a non-starter though, for the reasons you suggest.

Complete waste of time. Most of the new builds I've seen get the floors finished after the windows have been installed, so the mess created would be massive. On top of that, is the lift actually large enough to transport the replacement/old unit to/from the apartment. Finally, what about health and safety? There is not only a need to work from the inside harnessed up, but on the outside of the building there is a legal requirement to provide an adequate exclusion zone or some form of safety net to ensure that pedestrians, etc cannot be struck by falling debris, etc. That alone would be a nightmare, let alone expensive. 10 storey scaffolding? They are having a laugh

Do you need to replace the frames or just the glass?
