The Best Exterior Caulks of 2023

When a temporary seal is all that’s required around a window or door, such as for winterization, it makes sense to save a little money and frustration. One roll of Frost King Mortite Caulking Cord features enough material to caulk up to six windows, making it much more affordable than using tubes of liquid caulk.

This caulking cord is inexpensive and doesn’t harden, meaning that DIYers can remove any sealed joints with relative ease compared to liquid caulks. The user must simply unravel the tape, separate a rope of caulk, and press it into the gap with their fingertips. Once it’s in place, users can choose to paint it or leave it as is.

To be honest, we thought this rope caulk was a good deal, but only for some applications. It was very difficult to make it look smooth, so it wouldn’t be ideal for anywhere that would be easily visible. Also, ripping off decent lengths of caulk was a bit frustrating as it came off in smaller chunks. However, we really did like how easy it was to remove, which would make it an excellent choice for winterization.
