What causes popping noises in house?

One of the main causes of cracking and popping noises that seem to occur randomly in a house, mainly deep within the walls, floors, and ceilings, is known as thermal expansion.Click to see full answer. Regarding this, why does my house make popping noises?Popping noises may sound like they are coming from walls when the sounds are actually traveling down the air ducts throughout the house. The popping can sound rather loud as warm air expands or cool air shrinks the metal ductwork, causing them to pop.Subsequently, question is, why does my roof make popping sounds? It’s thermal expansion and contraction. The sun hits your roof and heats it up. As the lumber expands, it moves and it will rub against other pieces of wood that aren’t moving at the same rate. This movement creates the popping noise. Also to know, why does my house make popping sounds at night? Popping, banging or creaking, especially in the dead of the night, is startling — but in most cases, those sounds are just your home’s reaction to temperature changes. You can minimize some of the racket, and if the house is new, the noise probably will diminish over time.Is it normal to hear noises in your house?Certainly, some of the sounds you hear in your house are totally normal (your fridge intermittently running, the occasional creak of the house settling) but there are others that are cause for concern — indicators of what might need to be fixed, replaced, or even exterminated.
