I have several leaky spots in my house from settling. I didn't want to use spray in foam as it is so messy. The main reason I bought this was for a sliding French door that I can't quite get latched tightly enough. I don't want to have a contractor have my house opened up to fix this in dead winter. Especially when it's been below 10 degrees for the last week. This filled the bill quite nicely. Easy to use and about the same price or slightly less than the big box stores.
