Apparently 'her' windows leak. The surveyor seems to think it's a job I can do myself but then he perhaps overates my DIY skills. Is it terribly complicated?

How complicated it is, depends on what type of windows "Her" has got /forums/images/graemlins/smile.gif

You could have been a bit nicer in reply ???

The method depends on how fixed.......

Some are just bedded into mastic in the alloy frames .... others are bedded onto rubber gasket and bolted up to cabin sides without frames .....
others have a slit tube like rubber around the edge that squeezes into the frame halves and then bolted up to cabin sides ...

If you just want to delay the work for a season .... (I managed 3 seasons with mine !! Leaked literally day before flying out !! ) - is to get Car windscreen sealer or non-solvent contact glue ... run a bead around just into the rubber / seal edge ... I did it as a desperate action to allow me to leave boat till return few months later ... 3 yrs on - it's just started again ... so now it's time to do it properly.

Mine are the slit tube like affairs in an alloy frame channel in half sections. So I shall use old bike inner-tube cut and slit to suit with joint at top suitably glued and sealed.

I hope this will help. I have windows (toughened glass) in alloy frames, originally bedded in a rubber-like sealant. After about 12 years the sealant was showing shrinkage cracks, and in another 2 or 3 years the windows leaked.
I cleared out the sealant with a tool made by bending a bradawl and grinding its end to a chisel shape that could be run along the groove, lifting the sealant out.
The next step was to cover the alloy frame and glass with masking tape leaving only the groove showing.
With everything bone-dry, I filled with a polysulphide sealant, aiming to get it down to the bottom of the groove to leave no air-spaces: VERY inportant: so much so that it may be counter-productive to dig too deep.
It took less than one afternoon, and has been 100% successful for three years. In the Spring I plan to do it again with a UV-resistant sealant, and hope to get another 5 to 10 years with that.

Question to Piota ...

When you applied the masking tape ... to the glass. Did you fold the tape over the edge and up other side, or just strip each side leaving the edge bare to seal ? Or did you line up edge of masking tape with where frame edge would come to on the glass ?
I take it once all set in place and bolted up - you ran a sharp knife round to remove tape and "excess" sealant ?

The MK I has "car-type" windows set in rubber seals while the MK II has alloy frames IIRC.

One further point to think about is how they come to be leaking in the first place. If the seals are obviously perished then that's probably it. However with a deck-stepped mast and no compression post (again IIRC) the deck may be flexing under load from the mast which might continue to break the seals on the windows if not resolved.

Not wishing to be a prophet of doom - just something to consider.

Re: Question to Piota ...

Evidently I did not make myself clear: the job was done without removing the windows. The groove I refer to is that between the glass and the outside frame; about 3mm wide. The groove on the inside is about 2mm, too small to work on, but no matter: If the outside is sealed, the window is sealed.
The most difficult part of the process was clearing the groove at the top of the window, working 'upside-down' while kneeling on the side-deck.

Not too bad: depends on width of side-decks, etc. Did consider standing in dinghy alongside, but not steady enough.
Easier if you have space to lie down, and are fortunate enough to be ambidextrous.

Re: Question to Piota ... .... mmmm

I have narrow side-decks .... I'm short and fat ..... and Right handed.

So that lets me off .... back to window sealer !!
