Owning your own home

I forgot to include stripping crittall windows back to the galvanising by hand and priming/repainting, one of the windows is 4.9x 1.8m.
It’s taken me ages and i don’t think i could pay a tradesperson to do it to that level as it would probably be £3k+ and not be done to bare metal. 60 years of overpainting means they need to to stripped.
I’m using a mix of good locals recommended from here, north Kent trades who are happy to travel to SE London, friends with skills and my own time so adding 15k+ to the spend to be hands off and a firm to deal with everything isn’t unrealistic.
have been fairly shrewd with sourcing stuff and spent in the right areas and done shit loads of google time finding the right stuff, i’m freelance so have only taken on what work that comes my way and not had a weekend off since January and done plenty of evenings working after a day chipping away at paint.
Could have done it by throwing money at it but wanted to do it this way.

Have to add that i haven’t blinked at paying people to the work as they have all been top notch so far but was quoted £500 to ease half the windows and adjust the handles which i thought was a bit steep.
