Not really. Like I said, it would irritate me if the neighbors were doing that for hours on-end, night after night. The golden rule should be enough to tell me that I'm being a pest. Furthermore, many people dislike confrontation. Even if I go over all nice-like to the neighbor, maybe she tells me it doesn't bother her, but really she is irritated as hell, but feels like she has no place telling me what to do. Or maybe she just doesn't want to rock the boat and have a neighbor who dislikes her. Maybe she says it's fine because I'm being so polite, but two minutes after I leave he regrets it, but would feel like an ass coming over and saying, "Actually, I don't know why I said that. You're really bothering me.
There's not really much use going and asking the neighbors something that I probably already know. I've just started taking breaks, i.e., if I'm sawing all evening for two or three nights in a row, I'll take a day off. And I'm trying to finish by 9-9:15 instead of 10.
