For the past year, I've been hearing a bizarre loud, sharp sound by my front door that happens several times a day, especially in warmer months. We had the door re-stained in summer 2024, and shortly after that, the sound began. It's like something is impacting the glass, but there's never anyone around when I check—the cameras didn't catch anything either. During winter, it seemed to decrease, but now it's back. The door looks fine with no cracks or issues, and it's not the piano or any strings that are making the noise. I'm stumped and could use some advice on what might be causing this sound.

You might want to check for any loose fittings or sounds that could be happening due to the house settling. It could also be worth inspecting the door hardware to ensure everything is tight.
Maybe it's birds? We have a lot of them, and they sometimes fly into windows or glass doors. You often won't find any signs unless you catch it in the act or see a few feathers. Just a thought!
Have you thought about the possibility of ghosts? I know it sounds silly, but strange noises can sometimes be hard to explain. Maybe consider speaking with someone who knows about this stuff?
That's really strange! It could be that the door is heating up differently from the frame due to the new stain. Sometimes materials expand and contract at different rates, which might cause a sound. You could try putting some painter's tape between the door and the frame to see if it helps.
Good idea! I'll definitely give that a shot to see if it makes a difference.

Oh wow, I hadn’t considered that! I will pay closer attention next time it happens.
