Leaking windows

[cambridgedon]

:-[We have a 40DS. Both the port side windows have started leaking badly. Does anyone have any similar problems/how have you repaired the problem?

I met a Dutch owner of a 43DS who had bad leaks from the forward saloon windows. He had attempted to solve the problen with sealent arond the edges, but I think the windows will have to come out to do the job properly.
Is this a Jeanneau problem to which the Deck Saloons are prone??

I have a 2002 43DS in the tropics and have a dry boat so far.

Zan,

You for got the "knock on wood" part at the end of your "having a dry boat so far"! So hit yourself on the noggen a few times for good luck!

Marty

[Zanshin]

MartB - Ok, consider the self-flagellation to be done. I am heading off to the boat next week - it is in the middle of the hurricane zone and I will be sailing at the height of the hurricane season. But addictions cause us to do silly things...

[MartyB]

Yes you are correct, addictions do cause us to do silly things! Have a good time! Watch teh weather reports!

Guys

We have just taken our 36i through 30K winds and 2-3 metre seas for 17 hours and did not have a single leak anywhere.

The fact is we have NOT had a single problem with the boat. We have done nearly 1000 miles since launching in March and it just gets better and better as we come to understand the boat more.

Happy sailing.

Geoff.

My 43DS portals leaked badly crossing the Sea of Cortez, so I pulled them out slightly, took black 3M silicone , plastered the joint from the inside, then taped them down on the outside for a couple of days with blue masking tape. It worked well. Because these boats tend to get warm in warm weather, I had some window covers made from heavy white cloth screen. They snap on the exterior. You cannot even tell they are there from the inside, but they keep the interior much cooler and provide great privacy in a marina. They only cost me about $400 in Mexico

We have used (1999) SO 29.2 which had serious leaking in windows. I removed old silicon and add new, and those windows are now ok.

On one sail trip where we had waves over the boat cover I found afterward water from inside. Any idea from anyone how to start investigating where possible leaking points are? Water was salty so it was from outside, but was not from windows since below were no wet spots.

Hi,

This weekend when we got to the boat (JSO 29.2), there was a lot of water inside the boat. It was on the cupboards and shelves in both sides of the boat. After using a water hose to spray on different spots - outside of course, we found that the water was getting in at the small window infront of the mast (mouth shaped window) and the water then ran inside the ceiling and down. We need to have this fixed - How is the window removed, it is still sitting very good. Does anybody know what the small holes (app. ø4-5 mm) in the window is for ?
Any help will be appriciated.
Best regards, Finn - Denmark.

Check to see if they are attached from the inside to the outside

If I recollect correctly on our SO34.2 there were also small holes - which had then been covered with silver paint, this maybe where sealant emerges when the window's are screwed tight from the inside

I don't know for sure though

Hi Malcom,

There is nothing at all to be seen inside - no screws/bolts ! I guess that the windows only has been glued by something onto the outer surface.

We have a Sun Oddysey 49' 2004, a friend also purchased one in the same year. Both boats had leaking windows, the response from Jeanneau was that the water was coming in through the air vents so they sealed them up! A specialist came over from Jeanneau to check the boats at the time. Clearly there is an issue. We have tried resealing them but still find that they leak, so we go on looking for a cure?

I have a SO 35 2003.

While one of the port windows was able to be resealed, two of my coach top hatches leak through the locks in the hatches when it rains really hard. I don't know of any other way to solve the problem other than replacing them.

Currently buckets are doing the trick.

I have just had the windows removed and refitted on my SO32. This was done under warranty, and so far, so good. The stbd side coachroof windows were both leaking, and the port side were in imminent danger of starting to leak. The job the yard has done looks much better than the original factory fit. Apparently everything has to be squeaky clean and then the correct primers used on both surfaces before bringing them together with a special type of polysulphide sealant.

Public thanks are due to Westways for standing behind their product and getting it sorted before the warranty runs out.

Hi,

Just want to let You know, that I found the leakage, at windows fitted on my JSO 29.2. The water was getting in at the small holes in the window. The holes go all the way through the glass fiber - maybe they are used for keeping windows in position when they are fitted. I sealed all the holes and now the boat is dry ;D

Holes in question:




Merry Christmas

How do you go about "pulling them out" or how do you remove them without damaging them or the frame, molding, on the inside? I have a SO 43, 2002 and two of the windows have started leaking pretty badly. One happens to be directly over the electric panel.

[electricmonk]

annoying isnt it!!!!

The correct way to remove the windows on the SO43 is to use a narrow decorators scraper from the outside. Working round the window and literally peel it off. NOTE you cant do this on the DS model.

use something like this

www.ebay.co.uk/itm/DECORATORS-1-INCH-25mm-SCALE-TANG-SCRAPER-STRIPPER-CHISEL-KNIFE-PAINT-FILLER-/221148406764?pt=UK_DIY_Material_Paint_Varnish_MJ&hash=item337d78e3ec

Radius the corners of the scraper so it can't make scratches on the windows or the gel coat.

Refit the windows with SIMSON Fast Tack not sikaflex. You MUST rplace the black paint on the outer edge of the perspex, ordinary vinyl matt black spray paint will be fine, this will guard against UV derogation of the adhesive - yes I know it says its UV proof as does the sika product - it isnt.

Hi had this problem when i bought my ds 43 under recommendation the yard removed 4 window panels ( you have to cut them out from inside best tool i found 1" flexible blade scraper as sharp as you can get it mask up well inside and work your way round takes ages ) The holes in the top edges of the panes correspond to holes in the frames and are locators to hang the windows on when you reseal I used sabba (cut down some nails for pins and pull out when set afterwards) the yard had real problems getting even pressure on the curvature of the panes not that they fit that well especially around the corners result £150.00 a window and they all still leaked I have so far resolved the problem by completely filling to just over the outer face edge of the windows and lipped it over the face slightly sprayed the edges as others have recommended eight months latter and quite a lot of rain no more leaks i also found some seepage via the screws around the overlap and fair-leads topside its worth popping them out and resealing I also glassed in the two cut outs over the forward panes for the deck set fare-leads and re led these lines I think this problem was my first inquiry on the forum there were one or two pages on the subject then persevere surface preparation is very important clean and de-grease to the enth degree i have wondered whether using suction pads on the inside would make a better seal possible when re fixing they would need to be attached to some kind of brace or jig Hopefully for the moment I am past the problem

I have a Jeanneau Sun Odyssey 42DS 2010 for 6 months only. The right saloon front window is leaking when it rains. I've tried to fix by applying some Black 3M Marine Adesive Sealant, but it still leaks. May be I have to take out all of the old sealant and apply again, or do I have to take the window out and start from scratch? How do I take the window out without damage the frame or the inside material?

Have a 2001 launched 2003 DS40 and what a great boat. On passage from Antigua to Horta we developed a small leak around one of the front windows - we had a bit of an issue when in the Carib and did a patch as some have mentioned. BIG mistake. did patch and strayed with water ect and all ok but once on the ocean and movement and big seas and leaked.

In Horta pulled all the windows using a metal putty knife and sharp narrow cutting blade and removed them.  cleaned and reset with Sikaflex.  All ok until 3 years later and new leak when in Turkey.  Pulled them again and they guy who helped me was a pretty good boat guy and owned a repair yard.  He looked at Sikaflex and said that about the time the windows were repaired last time that Sikaflex had produced a bad batch and he would take samples and send to Sikaflex but response may take a bit of time - I said no and we replaced but did not use Sikaflex this time - If you need to know what he used I will contact him - But not only pulled all the windows as before but when resealed laid sand bags on them to add pressure to help seal better. 

Good luck

Hello all, I have a 1995 Sun Odyssey 32.1
My side windows are leaking. 
I had use temporary silicon and it worked well for years.
I resealed those windows this summer in a cleaner manner with Sika 295UV but it last about two month before new leaking.

I think that there's a lot of structural movement when sailing and it is maybe the reason why a small sealing joint is not lasting.

I intend to remove both windows completely, cleaning all the surface and use butyl tape for reinstalling.

any tough?

[andreshs1]

I think that the key is to use the Sika 209D primer and then 295UV

I am waiting for the stock to arrive to Hong Kong and I will be tackling the same on mine...

cheers

I recently helped a friend rebed the big window on his 45DS. In order to cut the window free we used a strong string as a cutter tool. One of us inside the boat and the other outside. We pulled the string back and forth and eventually cut all the old sealant. There were no screws holding the window in, only the adhesive sealant. Once free we cleaned a lot of the old sealant out and scuffed up the edge of the window and the seating surface of the boat. Then applied new sealant. I don’t remember what was used but definitely some that adheres and remains flexible. Then when we placed the window we made a wood frame and inflated an air mattress to provide pressure to the window while things set up. I have heard that it’s not leaking now. Definitely a few hours work for two people. When I see the boat owner again I’ll ask what he used but I bet there are a number of good products for this.
This is similar to how many windows in small planes are installed and it seems to work.

You should check your mast step (on deck, if your boat is deck stepped), and in the bilge (if deck stepped or keel stepped) for signs of distress. I think that most of these window failures are caused by the mast pumping up and down, flexing the deck of the boat and overstressing the sealant, which is not supposed to be stressed like this.
