Doors and Windows - window drain holes

Hi, I hope I'm in the right forum. We had Certain-Teed windows put in as replacement windows when we had our house resided a couple years ago. This year we have had a horrendous bee problem in the house and have traced a few as coming in through the drain holes in the windows. Now, the question....we can find the drain holes on the inside of the windows but can't find where they drain out to. The windows are sliders and are of two different types, some are with half screens and some are with full screens. Could it be that these drains have been draining under the siding? (Egads!!!!) Tonight my husband had me pour water into the inside holes and there was absolutely no evidence of the water draining on the outside. Since we have had numerous storms, where these windows have had to drain an awful lot of water since we had them put in we are starting to get uncomfortable, thinking maybe the wood under the windows is going to rot through one day. Thanks for your help;)

This post has had 9 or 10 looks, but no replies. EVERY vinyl window that I am familar with has weep holes or slots -- and they are really obvious from the outside. I can't imagine a company like CertainTeed would let the weeps drain ANYPLACE other than the outside. I'll check it out over the weekend at the glass shops that deal with these windows and let you know just what i learn.

Thanks Lefty,

If you could just find out where those weep holes exit that would be a big help. I think it is not CertainTeed, but rather our contractor, who has messed it up. He put these huge frames around the windows and, in the process, I think he covered them up, which does scare me a bit, as that would mean the water HAS been draining down under the siding, which means there could be some wet wood down there. If it is under there, then could that be where the bees are coming in? They are building nests under the frames, as they can get under the siding there. Should that have been made so they couldn't get under there? And, last but not least, is there a way we can get the frames apart to look for ourselves without destroying the siding or frames? Again, thanks for your help. I wish we had been smarter sooner, but we didn't have a clue as to there being a problem.

Yeah....he's covered them up.....they're at the bottom of the frame about 1/4 of the way from the left and right sides....a little slot that usually has a cover flap to keep bugs out.

Just one of the reasons I don't like welded windows......they all have some kind of "internal" drain system, and even when they are left exposed as they should be, they get plugged with dirt, spiders, dirt daubers ( little mud nest building wasps we have in the south that just LOVE a little hole like that) and so on......

A mechanical window ( screwed together frame ) has a positive slope to the sill and uses just gravity ( which tends to work morst places ) to drain water.

But since EVERYBODY in the window world had to have something "new and improved".........and they sorta missed it on the last part :) ......I guess we'll just have welded windows.

I've only put in about 20,000 windows......what do I know about how they work.......
