Why do old buildings crack?

Are cracks in a house normal?

A: Wall cracks are fairly common in both new and older homes and are often the result of normal house “settling” that can quickly, inexpensively be remedied by re-taping the joints—the seams where the drywall panels meet.

Are small cracks in walls normal?

Problematic wall cracks will typically start at windows, doorways or house corners. Generally, smaller hairline cracks are not cause for concern. These are usually the result of seasonal expansion and contraction of clay soils beneath your house over time, and can be easily patched and re-painted.

Can you just paint over hairline cracks?

For deeper hairline cracks, you may want to use a filler to fill up the cracks before applying a new layer of paint in the affected area. However, if an extensive area has been affected, you will need to scrape off the paint and then sand the entire area to even out the edges before applying a fresh coat of paint.

Why do walls crack at night?

The wood warms during the day, losing moisture and shrinking slightly. At night it cools, absorbing moisture and expanding a bit. As one piece of wood tries to move against another, pressure builds between the two. Finally the joint slips, causing the popping.

Why do houses pop and crack?

That loud popping noise you've noticed your house or deck making isn't a poltergeist or structural issue. Instead, it's the friction between your home's building materials as they contract and expand at different levels. Extreme cold air reduces the moisture content in the building materials, causing them to shrink.

Why do I hear random cracks in my 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.

Should I worry about my house creaking?

These sounds are usually not something to worry about, but if it becomes constant or you notice an increase in sound, you may need to listen. Soil contracts and expands. When the weather is hot and without rain, the soil will dry up and contract. When it rains, the soil will absorb the water like a sponge, and expand.

Why do I hear knocking in my walls?

Loose Supply Pipes

If you live in an older home, the hot and cold-water supply lines can become loose and bang against the straps that secure them in place. When this happens, the water pressure causes the pipes to move and tap against the wall or brackets. This can produce a knocking sound.

Why are my walls popping?

Temperature Changes

As the temperature in your house goes up and down, the materials used to build your house expand and contract with the heat and cold. Often this expansion and contraction causes popping sounds in the wood or other materials. This is why many people notice the things that go "pop" in the night.

Why do I hear noises in my house?

The many materials that make up your house — wood framing, plywood, glass, metal ducts, nails, plumbing pipes — all expand and contract at different rates. When a house cools at night, these materials may move slightly, rubbing against each other and making noises. Occasionally, they'll contract with an audible pop.

Why do I hear tapping in my room?

A repetitive ticking or clicking sound coming from walls and ceilings can result from the expansion and contraction of metal HVAC ductwork that conducts ventilation through these voids. When metal heats up, it expands; when the furnace stops pushing warm air through the system, the metal cools and contracts.

Why do I hear whistling in my house?

Whistling Window Noises

Improperly installed windows, worn weather stripping, changes in temperature and the simple passage of time can all cause an unwanted whistling inside the house. Not only is the sound annoying, it can also lead to energy waste.

11, 2016 -- An expert is warning about a modern-day phenomenon called phantom vibration syndrome, where people think their mobile phone is ringing or vibrating when it's not.
