Damaged Sill

[Gilwern]

Hello,

My bathroom window sill is badly damaged by water (it is beside the showed and was a bad bodge job). I don't have the money for a full bathroom re-fit, so I am trying to find a DIY solution for now.

Here is a plan:

1. Remove the wooden beam.
2. Fit a new wooden beam.
3. Fit a uPVC cover over the whole thing.

Does the plan sound reasonable? Do you have any tips or warnings?

Thanks
Gil

I removed the rotten wood.

I think I will try and build a new wooden sill.

Why replace with timber to rot again?

I was thinking I could perhaps do a better job of it and seal it better etc.

Do you have an alternative suggestion?

Is uPVC easy to cut to size?

It will depend on how accurate you mark out and how steady your saw hand is.

Some additional questions:

Red Xs
These little gaps had crumbly plaster (which I scraped off). What should I do about them?

Blue X
This horizontal section is bumpy and uneven. Should I just level it with shims and packers?

I suggest level the new window board with necessary packing and then when happy fill gaps with a reputable filler

Thanks for the suggestions.

When you say packing, what specifically do you mean?

Packings can be of any material, but waterproof plastic would be my choice. Here's the sort I'm referring to:-

Plastic Packers

These plastic packers are a great toolbox standby. Each pack contains 100 pieces in assorted, colour-coded sizes. You can use them for any job - levelling, spacing or packing - where you need consistent placing. So whether you're laying out tiles, lining up decking or spacing bricks, these...

OK, thanks for the help.

Can anyone suggest a way to fix the problem here?

How might I fill this massive gap?
