How to make your windows tight without wind coming through?

I would use the 3M window cover sets. Put the two sided tape on the window sill and the surface next to the window, not on the frame. As long as the tape is adhered real well to the surface you should be ok. I would try the silicone you use on cars to adhere the weather stripping. It is normally made for heat extremes if you find it in the automotive section at big box stores or get it at an auto parts store. That may keep the stripping in year round. You can also keep the window cover on year round. If it gets punctured you can repair it easily. Put down the tape that was left over around the rip, but not right at the edge, cut a piece out and attach it to the tape and shrink it like you did for the window. Trim close to the repair and it is good again. I always keep what is left to use the next year and for repairs.

First of all I would be calling the people who installed the windows. Even if they are off a little they shouldn't be letting air come in. To look for the manufacturer, lift the bottom window up a few inches and tilt in, there should be a sticker on either side where the window slides but inside deeper. If you can find it call them and see if there is anything they can do like get someone out to see why your windows are leaking.

If you have no luck there, the first thing is to go outside and run a bead of caulk between the window and the material that is next to it. Like aluminum, wood, etc. They most likely never did that and that is a must. Next you must caulk the inside. every little crack between the window and the wood must be sealed. Once that is done, you will se a greater difference. There is a caulk called "Quad" if you can find it it is very good. You don't need a lot. Cut the very end of the tip at an angle ever so small but enough for it to come out. Make sure you punch a hole in the caulk, usually on the bulk gun and you will be a caulking everything.

Now for your window and lock. What looks is happening is the part on the window piece isn't low enough the right side. In your picture I take it the window is locked? What I need you to do on this window is the same thing as I had you do on the last window, unlock it, lift it up, tilt it in. On the latch that the lock catches that is mounted, are they both screwed down? Check to see if the right side is screwed down. If it isn't that is your problem. You need to find a short flathead screw that will fit in there, it might even be in the bottom of the window. Screw it down tight. Put your window back together and see if it works, if it still does you might need to get a longer screw. I hope I have helped you out, good luck and best wishes. let me know how everything goes

I would use rope caulk for the winter months, and then just remove when weather is warm enough to open windows, it will peel right off.... it doesn't get hard. Its fast to apply too.... https://www.youtube.com/watch?v=3rSu99pOAI0 sure cuts the drafts in cold winter months for this old house.

Ace Hardware and Home Depot always has this, and it comes in gray. You can do this in an afternoon across my whole wall of windows. https://www.google.com/search?client=opera&q=rope+caulk+ace+hardware&sourceid=opera&ie=UTF-8&oe=UTF-8

ok, I have had a simlar issue; we need to atually have foundaion work done; and some of our windows are not properly sealed; I purchased this: https://tinyurl.com/ybn6szvz because it is alsmost crystal clear and these: https://tinyurl.com/ya5rjk3j and I purchased enough of the strips to go around the sill and the lower part of the window; I would also recommend purchasing the double sided exterior tape: https://tinyurl.com/yamj6vuh. and use it to stick the framing strips to the window sill and sides and top; cut the plastic at least 2 inches wider than each window and make sure it is longer than the window, which is why I got the kit for patio doors; then put the double sided tape onto the strips ( peel the backing off of the strips first; I found that the adhesive on the strips was bad; which is why I had to use double sided tape) ; then peel the backing off the double sided tape, then stick to the windo sill and sides; you can cut the strips and butt the pieces up against each other if needed to fill in spots; order at least 2 more packs than you will think you will need; now, after you have placed the strips, pull the center piece out of them and start putting your plastic up; start at te top; put it up agains the groove and then take the inner part and slied it back into the groove; work your waya round, keeping it tight, but not too tight. do the sides, then the bottom; since I did mine nice and tight around, I dodn't have to do any final tightening up of the plastic wit a hair dryewr. I also used good packing tape around the top and upper sides of our windows instead of the tracks because we don't open that part up; and we some times have high winds that will take anyone and anything on; so needed something to help hold the plastic on above and byond the strips. If I had had a cell phone at the time with a camera on it, , I would be putting up a tut, too

Thank you so much! Great way to solve the problem!

First I'd want to see how level my house is. It maybe that your windows are off due to the house still being out of whack.

All of the above ideas are great as temporary fixes but I'd want to fix the problem rather than patch it up. It may just be your sunroom that has sagged and needs to be shored up more. That gap under the window is pretty big I'd be worried that the roof has torqued and will eventually start to leak. Remember if the wall of windows has shifted that much it's likely the rest of the room has too. Look around the roof line outside and in. We can see our garage floor has sunken several inches over the years by the lines on the main house shared wall. Without those there is no obvious reason for the giant cracks in the concrete. It took looking for hints before it became obvious.

I agree with Oberlinmom1. The windows fell out of level and plumb. All the repairs mentioned are a band aid fix. You need to level and plumb the windows so they open/close properly and lock. The plastic cover between the windows pops off so the windows can be leveled and plumbed. Fill any gaps with low expanding foam in the Blue can after they have been leveled.plumbed. If you can't do it yourself call the company that installed the windows and they can do it for you. I could not live with energy efficient vinyl windows that aren't doing the job or a jury rigged repair.

wow thank you I’ll contact a window

company right away (the folks that corrected the pier and beam foundation only does foundations ) I’ll get a window company to come right away.) . Again thank you
