How to fix damaged window frame?

[jeijav]

Hi! We moved into a new place and this kitchen frame is damaged due to the water absorption near the sink. It’s an eye sore and Ive been wanting to fix this part but I have no idea what to do. I hope someone can give me ideas. Thanks!

That board looks like it  can be lifted up and replaced by another cut to size  if you feel your up to that.

option  2 is to use some gyprock wall corner  steel and create a  new  plaster edge.

Welcome to the Bunnings Workshop community @jeijav. It's great to have you join us, and many thanks for your question about fixing a window trim.

That appears to be an MDF splayed skirting. I'd suggest removing the damaged one and replacing it. You'll need a wrecking bar to pull it off the wall. When installing the new trim, make sure to paint all sides with a couple of coats before installation. This helps prevent water from being absorbed into the timber. The new trim can be glued and screwed into position. After this, timber filler is used to cover the screw holes and a final couple of coats of paint are applied.

Please let me know if you have any questions.

Hi MitchellMc,

I have the same problem as jeijev for my kitchen frame. Can I replace the MDF splayed skirt with a piece of timber if the rest of the frame is made of MDF? I'm not sure if doing so would wreck the frame over the long run if I have two types of materials that may respond differently to temperature and other elements.

Thanks!

Hi @newbie199,

Welcome to the Bunnings Workshop community, it is wonderful to have you with us.

If your situation is exactly the same as Jeijav's, then you are not really dealing with an issue with the window frame, but rather the architrave that is attached to the frame. An architrave is just a decorative piece that is installed to conceal the gaps between the window frame and the sheeting. It is not a part of the frame, it is not structural, and therefore it is very low risk.

Ultimately, because natural timber and MDF expand and contract at different rates, it would be best to replace the whole architrave, but it wouldn't be the end of the world if you just replaced the bottom piece. You might find that the joins at the corners open up a bit, but this isn't really a big deal.

Put simply, you wouldn't wreck the frame if you were to just replace the bottom piece.

Let me know if you have any further questions.

Jacob
