Repairing rusty Crittall windows

Only if left in a solution for 24hrs+ and these are in-situ window frames. Its not the MOST effective!

Phosphoric acid is a rust converter (available on Ebay) but check on a test piece that after conversion the paint used for over-coating is not affected.

I think 80 is comfortably more than Crittall put in his own country residence when he built it in the 30s. Can't help wonder if you bought a house or an office block!

I suppose a double fronted house could have (say) 5 x 4 casements front and back (40), plus a bunch scattered at the sides and a few dormers.

Whichever, it's quite a pile!

If I take some out I'll get them sand blasted and powder coated, but the problem will be getting the leaded lights out (and back!) intact. It all seems rather daunting on top of everything else that needs doing.

I remember (I think) using that on my old bangers in the 70s. Someone else posted this link

It's not small but it's a long way from being "a pile" - there are just lots of windows. I hadn't realised quite what a project we were taking-on.

Fun. I'm not sure there's any shortcut, unless blasting in situ might be an option for some of them.

FWIW I've always wondered how effective it would be to have a second sheet of glass outside the window & frame, wih a gap at the bottom. Idea being to keep rain off the frame & slow air movement on the glass.

Bit of a shame to have 80 casements that can't be opened.

...for sliding sash windows of course. Shouldn't take too much brainage to work out how to adapt it for casements.

take them all out, get them bead blasted galvanised and powder coated and put them all back
