Our metal skylight with a double glazed panel (lined inside with timber) is leaking. We tried silicon, but this didn't resolve the problem. An advice would be appreciated. Thank you.

I don't know exactly what you are talking about. It sounds as if it might be what is known as a pigeon box as found above the engines in a traditional narrow boat or it could well be something different, especially if its not on a narrow boat. I also ned to know how this skylight is fixed to the boat. If you want a good quality answer it would probably be best if you email me some photos of both the inside and outside the boat with one annotated to show exactly where you think the leak is. Send to Tony@tb-training.co.uk many thanks.

Its's one half of the skylight on a narrowboat. I'll try to take some better photos. Thank you.

I am sorry but there is no way I can do anything with that image. The forum crushes all the images down into not much more than a thumb nail. Please send by email to Tony@tb-training.co.uk and I will be able to look at them at their full size. Also can you give me an idea about how old the boat is or if fitted lather how long they have been fitted. At this stage I suspect that you may have rust under the fame pushing it away from the boat's roof but that is only one of many possibilities.

For other readers. I have got a photo and it looks like poor design to me because water pooling on the glass inserts will be higher than the inner frame lip so with any sealing failure will leak. I have advised Carol how to proceed to mitigate the leak but probably not cure it over the longer term.
