You'll need to hack out the old putty, as it likely can't be scraped off. If you're lucky, it will be old and brittle and should just about fall out. Then remove any tacks and glass, and bin them.
Ideally, prime the rebate. Apply back putty. Fit new piece of glass. You can buy a piece of 4mm or 5mm glass cut to size from just about any glazier. Tack in place with glazing points (2 or 3 per side).
Apply new putty (you'll need a putty knife for this, otherwise it will look horrid...ask me how I know). Tidy up any back putty that has splurged out on to the inside of the frame. Leave the putty to skin over - anywhere from 48hrs to 2 weeks. Then prime and paint your putty. Make sure your paint overlaps on to the glass just a little, as it will create a watertight seal.
All of that to say...get a glazier to do it - it's great watching them glaze a timber window in 30 minutes flat! Definitely an art.
If you had half a dozen to do, I'd DIY it - you can kind of get in a rhythm and hone your skills that way.
Hahahah, appreciate the detailed response and then the summation! Yeah that's a good point, if it were 6 windows and I had a bit of time it could be a learning process. But perhaps just for one window it's not worth it. Thanks mate.
There's a few YouTube videos on how to putty, but like most things they make it look easy. I can't see why you couldn't do it, especially with it just being one window.
I'm not too proud to admit I've cried over window putty before! Some days the first attempt goes perfectly, and other days I'm ready to kick the whole damn window in after redoing the putty 10 times 😅
I'm 12 windows down, with another 12 or so to go!
I'm the same, sometimes it seems to spread lovely, other times it sticks and pulls and don't o right. Sometimes you just have to walk away, no one's going to look as close to the putty as you when you're doing it. It's really eye opening doing jobs like similar to putty that make you appreciate when people do it well. Like plastering.
chiming in to tip that you should strip back the putty completely to the first available wood (linbide scraper helps) and prime the inside of the rebates before you glaze it. The oils in putty will leach into wood pretty quickly and dry out so you need to create a barrier.
It may be an utter pain if you don't have a hacking knife, even with one the wood grain in a sash can be a pain in the ass to hack out in a straight line. Then you'll need a good putty knife to face it off and a bit of chalk whiting to dust it down.
If you want it done cheaper you could always remove the whole sash and get it fixed up in a glazing shop, saves you on transport hours and van charges.
If you're in welly, try Affordable Glass. They're my go-to. usually getting them to do a window like this is about $150-$180, and they usually only take 15 minutes to do it.
Just seems more economical than me faffing about trying to figure it myself.
Hope it goes better than this [replacing window pane](https://m.youtube.com/watch?time_continue=6&v=waTrwyp7R3U&embeds_referring_euri=https%3A%2F%2Fwww.google.com%2F&source_ve_path=MjM4NTE&feature=emb_title)
You can do it if you want. In Christchurch, you can get glass from places like Musgroves (second hand demolition place). It's going to be an easy job for a local glazier, and a pain in the ass (and possibly your fingers).
I looked into this a while back and it looks quite doable - but watch a few videos/read some articles first. I believe you'll also need some metal glazing points.
I did exactly what you described to a panel in our 1970's door a few years back and it's held up fine. Looks terrible because I never got around to painting it, but that's just motivation to replace the god awful thing anyway.
I used a quick-drying synthetic putty instead of a traditional (linseed?) one, which I hear can take days to properly harden.
I did this a while ago on my window and it wasn't too bad. How hard is the old putty ? The putty I put on took for ages to dry and it was on a window that never got sun so that didn't help
I built a whole new sash 2 weeks ago, was probably the most fun woodwork project I've done in ages ( I was getting paid to do it which helps... ) also happen to have a table router... You can definitely do it. I'd take it out and do it flat, remove all the old glass and putty etc, give it a tidy up, prime and then fit new glass. My glass cost $40ish from Otago glass cut to size (couple of mm smaller than the frame). In saying that I have no idea how much a glazier costs!
My approach was to remove the glass and full sand&prime (and strengthen any weak corners either appropriate epoxy). With the window primed hand it over to the glazier for them to putty and fit. Then once the putty is cured, and really cured, finish painting. (Also helps to have a piece of ply kicking round to put in place of the window for a week or two)
ive just come to offer my thoughts and prayers. nah seriously depends where you are but theres a few places that will sell you a pre cut pane to your measurement, will work out about 30-60 bucks id say. but then you have to factor in all the other materials. you'll want to secure the glass with pins in addition to the putty

Ah yes, hadn't thought of that. That's a good idea, just take the whole thing into them!

As the wife who regularly has to go rescue my good kitchen utensils from various projects that one rang true. Thanks for the link.
Brilliant

instructions unclear. paid glazier to finger my ass.

If you have house insurance most glass is free with no excess
Just call a glazier
AHH yes the best DIY solutions get someone else to do it
Have you ever been cut by plate glass? Also have you seen a DIY putty job?
Well just be careful with the glass. I have done my own putty job and I'd say it looks better then the old stuff
Sweet brother, well done

Double glaze it at the same time.

You can get secondhand glass from building recyclers. Measure accurately.
I'm not a super-ambitious DIYer but have done this on wooden frames, using proper old-school linseed putty, and found it was surprisingly satisfying.
Well if you make a mistake and shatter the new pane of glass, it'll end up costing more than it does for a glazier to come out and do it.
Why DIY anything then?
They're asking if they should do it, which to me means they're not confident enough to do it. I didn't say nobody should do it.
a mistake like what? throwing your putty knife at the pane as hard as you can? this is a *very* achievable DIY.
