How to fix awning window sash?

Hi experts,

I have an awning window in this photo.

 

The bottom right corner of the timber sash has been damaged and the glass has moved in this photo.

Hello @DP7 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about repairing your window sash. 

Please note that working with glass is dangerous, an accidental hit with a tool or too much pressure applied to its surface could cause it to shatter and cause injury. Please make sure you are wearing personal protection such as gloves and goggles when working with glass.

If you are familiar with window sash repairs, the frame itself must be removed in order to re-seat the glass into the routered channel. The timber frame will then need to be re-glued and screwed or nailed in to prevent it from splitting again. At the moment the glass has slipped out of its channel and is being held in place with the other pieces.  Please make sure that the glass does not slide out any further to avoid damaging it. 

If you are a bit hesitant in regards to taking your window sash apart, I recommend engaging the services of a builder or handy person to help with the repairs.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you need further assistance, please let me know.

Hi @DP7 

The photos are a very small file size, so I'm unable to enlarge them large enough to see what going on exactly. Do you have higher resolution images you can share?

Good Evening @DP7

Welcome to the community Its a good place to get ideas on how to approach things. 

The wood seems to have perished or at the very least failed at the connection point. I would hesiate to attemp to fix this myself even if I was fairly competant in capentary and glazing. 

The age of the window and style probarly means its non shatter glass so if it cracks it will be in long shards 😕 and that is something that is not fun to deal with. As soon as you attempt to take the window out to repair it, the other sides will be weaker.

I would suggest a carpenter or glazier to repair the window. It also may be an idea to have a close look at other windows of your house. I say this as you have the same style of windows my mum does and they all seemed to fail around the same time.

Not an easy repair job I would suggest.

Hi @DP7 

thanks for sending these through. The first job is to very carefully revoke the glass. You will need a sharp blade in a Stanley style knife and wide chisel or similar to seperate that trim from the window frame on the outside. Don't worry if the trim splits as it will need to be replaced anyway. It will have brads holding it in place as well as several layer of old paint. And if you break or crack the glass, its not expensive to replace.

With the glass removed, the frame needs to come out by removing the hinge screws top of each side. The frame can now be rejoined where it has separated. First apply some Earls wood hardener to the inside sections of the joins as per the instructions. Once sealed use a high-strength wood glue to refit the frame together. Using tie-down straps in lieu ofd suitable clamps will work to hold the frame together during the curing process.

Give the frame a good sand, prime and paint as well as the new trim sections.. Fit the glass and trim. A silicone sealant will be required to sandwich the glass. Drill pilot holes in the trim and carefully nail in the brads after applying also a bead of wood glue. Refit the window.

I know that sounds all pretty straight forward, but essentially thats the process. Let us know how you go.
