What happens here

The presenter walks around the house, inspecting the siding and trim for areas that require caulking. He points out a specific corner where a piece of batten board runs into the corner board, indicating it was missed by the previous workers. He also notes that the metal vents are typically not caulked by siding installers, but for aesthetic and protective reasons, he will caulk them. He emphasizes that for exterior work, the caulking doesn't need to be as perfectly smooth as interior caulking. He demonstrates applying white caulk to fill gaps, even though the house will eventually be painted a dark 'green black' color. He uses a caulk gun to apply the caulk generously and then smooths it with a gloved finger to ensure good adhesion and a proper seal.

Goal: The presenter inspects the house exterior for gaps around corner boards, window trim, and siding joints, pointing out areas missed by the original installers and beginning the caulking process.

What they say

Hide

white. So let's walk around. I'll kind of like uh point out some things I'm looking for to actually um caulk. Now, one of the cool things is is the way they installed this sighting. The nails, they nailed it on, but the nails are hidden. So, I don't have to caulk any nail heads. But I don't see anything that stands out, you know, here. Uh they typically on houses when they'll install metal vents, there's going to be metal vents under there. Uh the metal vents are never the sideers don't ever those. These are actually vent set boards that have slits in it. So there's no cocking that needs to be done on the vents. So I'm going to cruise cruise around here, kind of look and see um what I can see right up here in the corner. You know, there's a hole missed where a piece of batting right there runs into the corner boards. Um that's something that I'm going to caulk. I'm going to come over here. You'll look in here this side. Um, and I have to say I saw the person caulking this side of the house and the person that was doing this. Um, she, it was a gal, she actually did a pretty good job. As you go around, she eventually wasn't here anymore. And they, uh, the guys were caulking it. Pretty apparent they didn't have nearly as much experience caulking. So, over on this side, I'm not going to see much. I do see a um, got some drip metal up here. I'm going to coaul, you know, this drip metal underneath it. Um, seam board right here, trim board where it meets the top trim board that was missed right there. This was installed after the ciders, the garage door. This needs to be cocked. Every one of these nail heads on the um the weather strip needs to be cocked. So that's um right here. There's, you know, big spots right here, holes that are cocked. Now, just going to fill that in. I typically on exteriors wear gloves when I coaul. Um because you got a lot of grain, a lot of wood right here. Your caulking doesn't have to be perfect like it has um in an interior. So, my caulking looks a lot different on the exterior. I don't have to sit there and sponge caulk everything. So, walk
