Is it normal for drywall seams to crack?

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.

Why are all my drywall seams cracking?

Cracks form due to stress placed on the seams. These cracks tend to occur around high-stress areas like windows, door frames, and corners. This stress can come from many sources. Temperature fluctuations can cause the drywall to expand and contract creating stress that cracks the seams.

How much drywall cracking is normal?

Contractors will often use a rough rule of thumb of 200 pounds per square foot for the average single-story house or 275 pounds per square foot for a two story house, however, the weight will vary greatly depending on the type of materials used in constructing the home.

When should I be concerned about drywall cracks?

Recurring cracks or drywall cracks larger than 1/8″ wide are usually signs of significant structural concerns that should be addressed as soon as possible. As the structural components of a home continue to settle, deflect, or deteriorate, the cracks will tend to lengthen and widen.

How do you stop drywall seams from cracking?

Drywall seams are normally covered with paper tape, which is generally known to be stronger and prevents cracking a lot better than fiberglass tape. A word of caution, avoid using mesh tape if you are going to use the “hot” quick-setting drywall mud.

HOW TO REPAIR DRYWALL (PEAKED JOINTS)

Will drywall seams crack in cold weather?

“Every unheated drywalled cottage I've ever been in always cracks after winter,” says Jeff Graham, a contractor in Little Britain, Ont. During winter, the cottage frame expands and contracts; drywall, attached to it, doesn't have much give, and can fracture. (Wood, on the other hand, deals better with winter movement.)

Why do drywall cracks keep coming back?

One of the top reasons why drywall cracks are happening often is because your home is already settling. After your home is built, the materials used to frame the walls dry out over the next few years, causing them to move slightly and develop small cracks at tension points near windows and doors.

How can you tell if a crack is structural?

Severe – cracks up to 25mm wide could be a sign of structural damage and should be inspected and repaired by a professional. Very severe – any crack above 25mm in width indicates serious structural damage and will need major repair work, which could include underpinning and rebuilding.

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.

How do you determine if the cracks in walls are serious?

Vertical cracks run the same direction as drywall, generally making them less serious. If the crack is horizontal or runs at a jagged 45-degree angle, it might mean there's a more serious problem such as severe foundation shifting or water damage.

Are settling cracks normal?

As it turns out, it's fairly normal for settlement cracks to form in the drywall from time-to-time, for a variety of reasons. This is especially the case for new homes, which have yet to settle onto their foundations. If your house is newly built, you should even expect some settlement cracks to appear.

Why do cracks appear on internal walls?

A fluctuation in humidity and even temperature levels can cause the expansion and contraction of door frames, stud walls and even window frames, which can result in cracking over time.

Are cracks in house walls 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.

Is house settling normal?

Settling is a normal process for a house, one that can reoccur due to environmental factors — so just because your house isn't brand-new, it doesn't mean you should stop looking for these signs. If you own a home, keep an eye out for signs of settling, especially the ones that indicate structural damage.

What do vertical cracks in the wall mean?

It is extremely common for newly built homes to develop vertical cracks in the walls a few months after the construction because the moisture in lumber varies and causes contortions when it shrinks. These contortions show themselves in the form of vertical cracks in the wall.

Can humidity cause drywall to crack?

The accumulation of moisture in the studs behind the drywall therefore can cause the drywall to crack. High levels of humidity in the home are therefore likely to cause drywall damage. In many cases, drywall cracks are the result of foundation damage. Wall cracks are often a sign of foundation movement.

Can low humidity cause drywall cracking?

Conversely, when the relative humidity becomes extremely low, especially over a short period of time, gypsum board will contract or shrink. As this occurs, the gypsum board will pull away from the tape joint, the point of least resistance, and the tape joint will crack.

What is a stress crack in drywall?

Stress cracks in drywall are usually found around corners, or where doors or windows have been installed. They are also commonly found where two pieces of drywall butt together and you'll see long horizontal or vertical cracks in a straight line along the seam.

What do horizontal cracks in drywall mean?

Horizontal cracks in drywall are often indicators of foundation problems. These cracks can be caused by poor soil below the foundation, water damage, and more. Horizontal cracks in concrete walls often indicate serious issues as well.

Do cracks mean foundation problems?

Fine, small cracks in the exterior walls or on the steps are usually nothing to worry about. Exterior cracks that are large and have a zig-zag pattern may be a sign that there's something wrong with the foundation. Brick cracks or bricks that are protruding from the wall should be checked.

Are hairline cracks anything to worry about?

Hairline cracks of less than one millimetre in width or slight cracks of between one and five millimetres are generally not a cause for concern. If you begin to notice these, they can generally be filled and painted over as they're a crack in the plaster but not in the wall itself.

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.

Does a house ever stop settling?

Does a house ever stop settling? A house will likely never stop completely settling. Most settling does occur within the first few years after the build, however, as the new house finds a place on the foundation and in the soil. You might notice a few inches over the years.
