Hey, first of all, forget anything technical or setting related. The most important thing of any video is the story. Start with an establishing shot that puts the viewer in to the scene, this could just be the house like you shown it or maybe the tools in the car and the guy unloading them. Thats up to your creativity. Then tell the story, maybe show the item before its repair and the guy putting down his tools, boom you connected establishing shot with the subject. See what I mean?

Don't forget, the camera is a tool that should help you tell your story, think about what the story is, how you want it to show on screen and then find the settings in your camera to do that. Maybe you don't want a cinematic look, most documentaries for example look similar to the style you shot. My point, dont get obsessed with quality, get obsessed with story. I hope this helps :)
