25+ year old windows - replace?

[TTCorHouseReno]

I've bought a house built in 1995 and the windows, doors and patio doors are the original. The windows are wooden frames, double glazed, which open using one of those long handles along the bottom, with the notches underneath the handle to choose how open you want them, with a catch further up to secure it when closed (no idea what this style is called, apart from outdated as hell). The windows are pretty shit, we can feel a breeze around the seals, the house is freezing without any heating on (although appreciate it is November!) The upstairs windows are drenched in condensation every morning. Some of the trickle vents are broken and won't open at all. They have been re-painted badly by the previous owners with paint splats on the glass and mis-matched colours throughout the house. We are thinking of just biting the bullet and replacing the lot but terrified by the prices of windows, will it be worth it?

In a very similar situation. Weighing up whether to do now (before moving in) or try some restorative measures to fix blown double glazing units etc. no advice but lots of sympathy!

Sounds like the house I’ve just brought!! Ours aren’t original but say the vendors surname and Jan 2001 in writing inside the frames!

We need to do other work so we are just going to live with the cold (& noise as we are fairly near a Motorway) and do them individually as we do the house up and hopefully save money. We’ve got a local double glazing company that we’ve used for other work and they said it won’t be much more expensive to do it that way than all in one go.

We're replacing all of ours except one (installed in last ten years) as part of a house renovation and it's considerably cheaper doing it like this via a builder than using a double glazing company. We have to get it checked by building control as the builder can't issue FENSA certificates, but we're already using building control for the renovation so it hasn't added to costs there.

It's 10 windows, 3 bay windows and 3 external doors for just over £10k.

They are probably casement windows
You could reseal them and repaint them

Paint splats can be scraped off

We have this in our 1990s estate. Almost everyone has replaced them with uPVC windows.
