This homeowner used spray foam in an attempt to keep mice from entering the basement.
How Mice Get into Homes
After spending some time with the homeowner to gather some information our technician began his inspection on the exterior. It didn’t take long to focus in on the basement window frames. Wanting to be sure that they were properly sealed on all four sides our technician got down in the snow for a closer look. Low and behold, the top side of the basement windows had not been properly sealed at the time of installation and there was a gap that lead right into the basement. This is a common shortcut taken by builders and contractors who are more worried about water than mice when they build a home.![Mice leave staining behind as they squeeze themselves in and out of houses](https://www.skedaddlewildlife.com/wp-content/uploads/2016/03/Mice-leave-staining-behind-as-they-squeeze-themselves-in-and-out-of-houses.png)
