Sealing a window is different from sealing a bathtub. Some windows require exterior, and some need interior work. Let us look at some of the most commonly used ones:

Painters or acrylic caulk

This is perhaps the most frequently used and also the cheapest caulk you can get. You can use this for covering small holes and cracks and then can paint over it. You can also use it on wood, drywall, masonry, and other porous interior building materials.

Vinyl Latex

Siliconized Acrylic Sealant

This combines the ease of acrylic with the strength and durability of silicone. It is also tougher to clean it up but makes a strong sealant for materials like glass, metal, tile, etc.

Pure Silicone

For windows which receive a lot of rain and have a problem with mildew, this is the best option. It lasts for a long time and works well on non-porous surfaces. It is flexible and strong and not very easy to clean up.
