Can cold weather cause cracks in ceiling?

As the dryer winter air normally infiltrates the home the home itself can become dryer. This drying of the home air and the materials used to build the home results in the materials shrinking a bit and the small cracks will form. Usually the cracks will form where sections of drywall meet.

Can humidity affect drywall?

How Humidity Impacts Drywall and Paint. Temperatures, humidity, and air movement directly affect how long it takes for drywall and paint to dry. The longer it takes the material to dry, the more vulnerable it is to failure, mold growth, cracking, and more.

How can I lower the humidity in my house?

Can moisture cause plaster to crack?

Dry shrinkage cracks are due to moisture loss after the plaster has hardened and the plaster will always shrink and Crack.

Can heat cause cracks in ceiling?

Is it normal for houses to have cracks?

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.

What causes cracks in popcorn ceiling?

What causes non-structural cracks?

Many factors can cause non-structural cracks, such as poor conditions at original construction, poor concrete mix, rapid curing, or changes in moisture due to the cycle of seasons. Foundations shifting, hydrostatic pressure, vegetation, or trees can also cause non-structural cracks.

What do settlement cracks look like?

Settlement cracks in walls can be vertical, horizontal or diagonal and in floors they aren't necessarily straight. They can vary in width but, if crack widths are less than 2mm wide, they are unlikely to affect the structural stability of your home.
