Why Do We Caulk Around Windows When We Install Them?

When it comes to window installation, caulking around the perimeter of a window is one of the final steps in the process. It is usually a step people choose to DIY themselves, recruit a friend to help with, or sometimes just skip altogether. However, if not done correctly, caulking can make or break the efficiency of your new windows.

What is Caulking?

Caulking is a waterproof sealant that is used to seal the seams of different structures, usually after installation is complete. Caulk is typically made out of a flexible polymer such as latex, acrylic, or silicone because of their waterproof properties, as well as their ability to absorb vibrations without cracking and adjust to temperature variations. Caulk can also be composed of a combination of all three materials.

Caulking is Necessary

While it may seem like an extra step in the process, caulking around your windows is absolutely necessary. The purpose of the caulking is to prevent any water, moisture, insects, or air from penetrating between the windows and the insulation. Without a proper seal around the windows, there is then room for air, the elements, and moisture to grow mold and slowly cause damage to, not only the windows, but also the window frame on your house. If left untreated, this kind of damage can lead to needing to have the entire window frames replaced due to moisture disintegration. Also in these Chicagoian winters, a good caulking helps to keep the heat in your home and the frigid air outside where it belongs. If you are worried about potential damage that already exists on your windows, you can check the signs and symptoms of what a broken window may look and feel like.

Caulking is NOT Cosmetic

While it may seem tedious, caulking is an absolutely necessary step, not a cosmetic preference. However, caulking does come in a variety of colors, such as white, grey, clear, black, brown, etc. just in case you are worried about it ruining the aesthetics.
