Around my living room window i see little crack (pic attached) from where cold air seems to enter. There are no cracks on the exterior of the house.
Can anyone suggest what is the best product i can use to cover these cracks.
Thanks in advance

I realize that you don't want to proceed with the project but I thought I'd answer anyway in case someone else is curious. I am a licensed contractor and my company specializes in basement remodeling; we have done several window expansions or additions in concrete foundations. A few things:
- You definitely need a permit for this project (though you don't need to hire a contractor) this is a structural modification and needs to be done correctly.
- You definitely need a structural engineer to write you a letter after a site inspection stating his recommendations for keeping the structural integrity (when you get a permit, they'll require this any way.
- If you are making a bedroom in the area you are adding a window to, you'll want to make sure that the new window you put in meets egress code for inspection/permit reasons.
Though you can support the new opening with pressure treated wood (according the engineers prescription, of course), most likely the engineer will recommend a steel frame in the newly cut opening. We use a 4"x4"x1/4" steel frame that the engineer signs off on. You can have one made to fit your opening at your local steel fabricator. (see pic below)
After you install the frame with bolts into the concrete and silicone sealant around the entire perimeter, the installation of the window is a piece of cake.

It looks like the caulk there is old and cracked. Scrape it all out so you have a good surface to work with and use a premium acrylic caulk. DAP extreme stretch or 230 would be good choices if you dont want to work with silicone. If the gaps are larger than 1/4" you should use window expanding foam or backer rod first to fill the gap before caulking. Then use a wet sponge and your finger or caulk tool to smooth out the bead
