Danny Lipford: Don’t underestimate what a significant impact you can make by simply sealing up all of the gaps and cracks.
Allen Lyle: You know, if you were to take all of those gaps and cracks and combine them, on the average house, you’d have a hole about one square yard. Yeah, three feet by three feet. That’s why it pays to seek out and seal those cracks. But easier said than done, right? Have you been down the caulking aisle lately? Options are confusing, so let’s look at just a few of them.
A lot of people go straight for that 100% silicone. Great idea. If you apply it correctly, practically guarantees a waterproof seal. Here’s the drawback, look over here. When you look at a crack like this, silicone is clear. You put it on, you’ll still see the crack. You cannot paint this, silicone will not accept paint.
So, you may want to go with a siliconized latex. Either one is great. When you’re talking about outside make sure it says “exterior” on it. Or in this case, you’ve got flashing, windows, doors. That tells you this is for the outside.
When you are using it, a 45-degree cut on the tip. I don’t like to go down any further than a quarter of an inch. Gives you more control over it. One other thing, when you’re looking at the caulk, look for something that has something in it for mildew.
Also, you might want to think about picking up a can of this, because not all of those cracks are going to be sealed with caulk. Expandable foam is great for filling in those larger voids that caulk simply can’t seal. So, seal it up. Save that energy.
