Water damage on window board

irishbuzz

Hi All,

I've noticed quite a bit of water damage on one of our window boards. The windows and boards were fitted 2.5 years ago but I only noticed it in the last few weeks and I actually think it has gotten worse in the short time since. Originally I thought that the black was just some discolouration from the plastic seam but as you can make out in the photo there's some blackening also happening now away from here. There's no noticeable water sitting on the top of the board.

Does anyone have any suggestions on how I would go about resolving this and also any tips on how I can possibly clean any of the black away?

Thanks

Ideally there would be a drop channel where the black is. It's condensation from your windows gathering on the window and dripping down . Drip channel catches that and allows it evaporate.

To stop this. I'd probably remove the sill, put a drip channel up against the window frame. Silicone the ends and slice off that black bit and reinstall.

Otherwise it will just get the same again in future.

The fact that timber is so black, tells me that board is sopping wet. The edge of the timber against the window was probably never varnished or lacquered, and the water is soaking into the board through that.

You'll never get that black stain out of it. If you want to keep the varnished look, you'll have to replace the board, but before you re fit it, completely varnish the board including the edges and underneath. Give it 3 coats, and when it is re fitted, run a strip of clear silicone across the gap to seal it up.

Or you could wait till the summer when the board drys out, and you could paint it, and silicone it up.

I appreciate the replies. Thank you.

It looks like you're correct. I originally thought the damage was on the surface but I notice now that when viewing it 'front elevation' there's a bulge around that area. The far edge must be soaking it up.

Oddly enough every window in the house was fitted with new windows and boards at the same time but this is the only one showing any issues. Hopefully, it stays that way.

It will have to come out. It's probably not a job I'd feel comfortable tackling myself (a dangerous thing to admit in this forum perhaps) but I'll leave it until the weather is a bit better and get someone in to sort it. I can do the patch up and paintwork afterwards.

Thanks again for the help

Be care who you get, did you see what these "professionals" did to that lads' window boards:

Probably safer to try any work yourself first unless there's someone you can trust

Remove window board.

Get some 16mm self adhesive in any DIY or electrical store. Stick it down silicone both ends and silicone between window and the trunking. This is the new drip tray. Moisture can gather here and evaporate at leisure.

Now get your window board trimmed down by 16mm and butt it up against the trunking and stick it down.

The window board in the picture, looks like veneered MDF with a solid lip, if it's wet and swollen there is not a lot you can do with it.

Can you check for drain holes in the window frame. There is quite a lot of water inside the frame seal, really shouldnt be there. You need to check where this is coming from.
They look modern enough; double glazed ? that condensation should not be dripping down either.

Its quite common for the drain holes to be blocked or not fitted at all, this water builds up over time and eventually spills over inside.

Bleach will get rid of mold but extract water from kitchen and bathroom with fan if you want to remove wood use multitoolband put in new wood
