1 AnswerMathematics6 years agoAnyone know what causes sawing wood sound in the house at night?
Sometimes, I will heard some sawing wood sound whenever I am in my bedroom. The sawing sound always appear on the night time(probably beause I only go to my bedroom at night) the sound have been for like 1 or 2 months.
I live in the city and there are no forest nearby. My house is a 2 floor terrace house. I think the sound came from the roof or outside the house.
