Mold in corner of window frame?
 
1 Attachment(s)
Hi, I'm a relatively new homeowner and I've got Crestline windows throughout the home (home is 40 yrs old, would guess windows are less than 10 yrs). The frames on the double hung windows are totally encased in vinyl but the horizontal double gliding windows have wood on the inside where the window slides. All of the double gliding windows have some degree of mold growing in the corners. Will this eventually rot the frame? I have wiped them out a few times but it comes right back. Is there anything I can do to prevent it (other than opening all the windows after a rain and physically drying them out?

Have you tried a diluted solution of bleach?? Bleach will kill the mould. Make sure to rinse well after and if need be run a new bead of caulk.

I do not like to see the raw wood around the windows. Wood being a sponge to moisture I cant help but think that some sort of sealer for the wood is called for. What, I am not sure.

I hope that someone more in the loop than I will follow up with how to seal that wood!!!!!!!!!!! I will follow this thread to see if you get an answer to that question.

I am going to disagree with my friend Mickey.
Bleach will not kill mold and should not be used on wood, It has been proven that the mold may come back even worse than before!
You can make a mix of 1/2 gal. white vinegar
1/2 gal. hydrogen peroxide-common peroxide available from your drugstore
1 cup boric acid
keep closed tightly
mix well - use in a spray bottle on a dry surface.
Ore use a one of the products for mold such as http://www.concrobium.com/atHome_howItWorks.php
Check if the weep holes in your windows are open and that you have a tight seal at your window.

Hey Thanks your knowledge never ceases to amaze me Mossy. What would you do about the unfinished wood on the window frames??

mossypath 09-04-2011 04:27 PM

My guess is there is a light factory finish on the wood. What CRESTLINE used? a call to them would tell you. Why I hesitate to give a answer is the last clad windows I set the wood had more of a waxy like finish and the finishing instructions were to avoid this areas.

can you post a pic back farther? i cant understand why i'm seeing that wood,thats a laminated piece of wood that i don't think should be exposed

Thanks for the replies. Tom, that was my gut reaction too. I had started to think along the lines of mossy's reply, that maybe they have some kind of light coating on them. Since they are double gliding, one of the pieces of wood gets somewhat covered by the vinyl of the window, and the piece on the other side is basically left exposed to the elements. I've got 8 of these double gliding windows in the house and all have the exposed wood (and mold). There is a groove that runs down the middle of each piece that I'd think would let the water run out. As you can see, they are clad on the side facing away from the house, and the side perpendicular to the house. Just the side facing the house is uncovered.

Here are some shots from further out, hopefully they help. (Disregard that awful fence in the background. The city is running new electricity through the yard and I don't want to get a new fence until they are done.)

that groove is most likely a spline that a jamb liner trim piece would lock in to

scottyv81 09-04-2011 10:50 PM

That makes sense...so they are likely missing that trim piece? Maybe I'll give a call to Crestline to see if they can either tell me how the window should have been configured, or what I can do to prevent the wood from getting damaged.

Tom,,,:thumbsup:
:wallbash: I missed the totally encased in vinyl part and was thinking clad.
If I ever have a problem, I would want you on my side.
Thanks

You might even email your picís to them.

Looks like I know what is missing now and what I've got to do to fix it, thanks again!

I'd like to read about this proof that bleach will cause mold to come back even worse than before. I suspect that the "proof" is something written by a seller of some magic mold killing potion. Not only will bleach kill mold, but concentrations as low as 5% have been proven to break mold organisms into their component parts to a degree that they are no longer even considered allergens (University of Arizona, efficacy of sodium hypochlorite on fungi). Any borate treatment is highly effective against regrowth of mold organisms.

I would like to move this discussion on mold to its own thread! :thumbsup:

I would welcome your input and anyone else who wants to join in.
