Hi All,

Found some tiny leaks/dribbles in the recent naff weather.

Before I replace the windows/hatches is it worth removing and re-sealing or should I just replace?

Hi I would recommend Captain Tolley's creaping cracking cure available from your local chandler.  We have used it with great success on leaky windows.  Though it often needs several applications to work.

Best wishes

Even if you replace the windows, assuming you do it yourself, you've still got to re-install, so the only delta is stripping the window apart, cleaning and resealing. The most difficult part is getting separating the aluminium frame, four small and likely corroded screws to remove and then the old sealant. I've found that a sash cramp makes a very good rack, put a piece of cord through the end two holes to either end of the sash cramp and wind open. It's a direct pull, there's no pressure on the glass and so less risk of damage. Hadlow Marine can supply all the bit's you need inc new BA Interscrews of different lengths.

Done 6 this summer, still got two to do. PM for more info

Did you get new seals, or just rebed the existing windows/frame?

I used raliseal to bed the glass to the frame and the Alba BR to seal the frame to the GRP.
 
Do remember to seal the alloy faces together when you assemble the frame or you have a small hole where the glass stops.  This can be fixed by injecting raliseal under pressure.

Originally, 10+ years ago, I got new rubber channels (Portmore, Southampton), this time I'm re-using as they are in reasonable condition - it's the silicone sealant that failed (but they only spec 10 yr life). This time using black Sikaflex between glass / rubber and aluminium and white when remounting the windows, much easier than the old silicone sealants. JR recommends just using Sika and no rubber, but I'm not sure how you centralise the glass in the frame with just Sika.

Tim
I am not aware that JR has posted an item on the Technical Section. May I suggest that you contact him direct.

Can anyone explain the following :
Last year I refitted all the starboard side and forward port side windows. I've still to do the two large port side windows. However the leak that used to drain into the aft corner of the galley has been solved. How on earth did water find it's way either through the main bulkhead or over the top of the cabin liner? Or is it just a coincidence?
