Hello there,
I would appreciate your advice on repairing the window frame. Please see the attached photo.
Kind regards,
Hi @emmab1986,
Thanks for sharing the photo. Unfortunately, the window sash itself appears to be quite severely deteriorated. The bottom rail beneath the glass is extensively rotten and has reached the point where it's beyond a simple filler-and-paint repair.
From what I can see, both the window and the surrounding external timber trim are of a fairly rudimentary construction, likely handmade or site-built many decades ago. It's actually stood the test of time remarkably well, but the timber has now reached the stage where significant reconstruction would be required.
To properly restore the window, the sash would need to be dismantled and rebuilt with new timber components, then re-glazed and reassembled. The surrounding frame and trim would also need careful inspection, as there appear to be multiple locations where water could have entered over the years and contributed to the decay.
Given the extent of the damage, I'd seriously consider replacing the entire assembly with a modern prefabricated window unit. By the time you factor in the labour involved in rebuilding the sash and repairing the frame, a replacement window is often the more practical and cost-effective long-term solution. It would also provide improved weather sealing, durability and energy efficiency.
Unless you have experience rebuilding timber window sashes and working with glazing, this isn't really a DIY repair. A glazier may be able to assist, but custom rebuilding of old timber window frames is quite specialised these days and can be expensive. In many cases, that money is better invested in a complete window replacement.
Let me tag @Nailbag to see if he has any thoughts.
Please let me know if you have any questions.

Hi @emmab1986
Looks like a very decades old awning window by the top of frame hinges. As @MitchellMc highlighted, the frame appears to be well past repair. And I think it would be highly unlikely you will be able to source a direct replacement even from a specialty period building material supplier. A custom made timber replacement will be your best long term solution. Then you should hopefully be able to repurpose the glazing into the new window to at least maintain that part of history.

Can we remove the rotten timber at the bottom, then fix the glass window in place using builder's bog? The window does not need to be operable. thanks!!
Hello @emmab1986
I'm afraid this window needs a proper restoration, and builder's bog will not be enough to repair the damage. Removing the frame at the bottom is dangerous as the glass will slip out. I suggest following Nailbag's suggestion and getting a custom-made timber replacement. Please be careful handling glass an accidental knock with a tool or when too much force is applied could cause it to shatter and cause injury.
Please remember to wear personal protection such as gloves, goggles and a mask.

Thanks @EricL and @Nailbag
I'll ask a handyman to do as you said.
