Why Are My Drywall Seams Cracking? (And What to Do About it)

The most common cause of drywall seams cracking is inadequate support or improper taping. When installing drywall, sheets must be properly secured with drywall screws, and drywall mud should be applied evenly over the seams.

Additionally, use mesh tape to reinforce the drywall joints. If you don’t take these steps, the drywall will be more susceptible to cracking.

Other causes of drywall cracks include uneven wall surfaces, high humidity, foundation problems, water leaks, and natural settling of the home.

If you are unsure why your drywall seams are cracking, it is always best to consult a professional to ensure the issue is correctly identified and repaired.

How To Fix Cracks in Drywall

Pre the drywall – use paper or drywall mesh tape to cover the crack. Apply the paper tape with joint compound, and then allow the joint compound to dry.

Sand the paper tape – smooth out any ridges or excess joint compound. Once you’ve finished sanding, you can apply a second layer of joint compound and paper tape to create an even finish.

Once the second layer is dry – you can sand it again to achieve a smooth finish before painting. It’s essential to be sure that the paper or drywall tape is completely covered with joint compound with no gaps or cracks.

This will ensure a smooth finish and make it easier to paint the drywall. When fixing cracks in drywall, caulk, drywall tape, and joint compound are your best friends. You can fix the cracks with a few simple steps and make your walls look new again.

Causes of Drywall Cracks

Drywall cracks can be caused by hairline imperfections or the studs not being straight. Fluctuations in temperature and humidity levels can also cause drywall to swell, warp, shrink, or form hairline cracks.

Improper drywall installation is another reason for cracking, as it can cause movement in the wall due to not being firmly secured to the studs.

Poor quality of drywall can also lead to hairline cracks due to weak bonding between the layers.

Also, vibrations from everyday items such as washing machines and vacuums can cause hairline cracks.

No matter what causes these hairline cracks, they tend to grow over time and must be addressed quickly.

How To Prevent Drywall Seams Cracking

One of the most common DIY drywall repairs is on small cracks along drywall seams, where the two sheets of drywall meet. If you want to prevent these small cracks, there are some steps you can take.

The first step is to use quality materials when installing or repairing drywall. Make sure that any screws or nails used for installation are the correct size and length. If nails are too short, they won’t hold the drywall securely, which can lead to nail pops or other problems.

Another way to prevent small drywall cracks is to use joint compound with mesh tape when finishing drywall seams.

Mesh tape with joint compound can help avoid drywall cracks

The mesh tape will help keep the joint compound in place and provide a stronger bond between the drywall sheets. Additionally, use a wide putty knife when applying joint compound to ensure that the joint is sealed and smooth.

Finally, inspect your drywall regularly for any signs of small cracks or nail pops. If you spot any problems, address them quickly before they worsen. To fix small cracks and nail pops, simply fill them with joint compound and apply a second coat of compound before sanding the area.

By following these tips, you’ll be able to prevent small cracks and nail pops from forming in drywall seams. With some maintenance, you can keep your walls looking neat and tidy all year round.

How To Keep Cracks in Drywall From Coming Back

Once the crack in your drywall has been patched and is no longer visible, it’s tempting to forget about it and consider the repair complete.

However, if you don’t take a few extra steps to reinforce the wall around the patch, there’s a good chance that pesky crack could reappear.

To avoid having to repair the same crack several times, here are a few tips for keeping your drywall repair from coming back.

First, always use lightweight joint compound when filling in the crack or hole in your wall. Standard drywall compound is too hard and will eventually cause the patch to separate from the surrounding wall.

Also, ensure you feather the edges of your patch with sandpaper and allow it to dry completely before painting.

Next, reinforce the area around the patch with fiberglass mesh joint tape. This thin layer of protection can prevent cracks from reopening in the future and help stop new ones from forming.

Finally, for extra insurance against cracks reappearing, you can use a drywall anchor or two to fasten the patch and surrounding wall together. This will also help to ensure that the repair is stronger than ever before and less likely to give way to cracks in the future.

Do Drywall Cracks Mean Foundation Problems?

Cracks in drywall can indicate a structural issue with your foundation. This is especially true if the cracks form corner beads or run diagonally, as these are tell-tale signs of movement occurring in the foundation.

You can also tell if you have a structural issue if the crack is running diagonally. This indicates that one corner of your wall has been pushed or pulled away from its original position due to a foundation problem.

If you notice any corner beads or diagonal cracks in your drywall, you should call a professional drywall contractor as soon as possible.

They will be able to determine if an underlying structural issue needs to be addressed. Ignoring the problem can lead to further damage, which could be much more costly and time-consuming in the long run.

If you’re unsure if you have a foundation problem, it’s always best to consult an expert. They can accurately assess the situation and ensure that your home is safe and secure.

Remember, cracked drywall can indicate a structural problem with your foundation. Stay vigilant, and don’t ignore corner bead or diagonal cracks, as they may be trying to indicate high-stress areas in your home.

Can New Homes Have Drywall Seams Cracking?

As new homes settle over time, homeowners may notice sheetrock cracks appearing on the walls. While this is a natural part of the settling process, it can be disconcerting when you first move into your new home and see these blemishes popping up.

If you do have drywall cracks in your new home, don’t panic! The cracks may be small and easy to ignore, or you can use a lightweight spackle to fill them in.

It is important to remember that these new homes are settling, and more cracks may appear over time. It’s not always foundation issues to blame. Therefore, it’s best to keep an eye on the walls for any new problems and repair them as needed.

Regardless of new home settling or drywall cracks, homeowners should take the necessary precautions to ensure their walls stay in good condition.

This includes cleaning away dust and dirt and using gentle cleaners that won’t damage the sheetrock.

Additionally, use anchoring systems when hanging pictures or shelves, so you don’t accidentally cause any new cracks.

It’s natural for new homes to settle, and drywall cracks can be safely repaired, but keeping an eye on them is essential to spot any new problems that may arise.

Can Leaks and Water Damage Cause Drywall Seams To Crack?

Water damage, particularly leaks and flooding, can cause drywall seams to crack. Over time, pieces of drywall can separate at the joints where they meet due to warping caused by exposure to water.

This can create gaps between pieces of drywall that allow moisture and dust behind it. Cracks in drywall seams not only look unsightly but can make a vulnerable point for further water damage to occur.

Knowing how to identify and respond to drywall seams cracking due to water damage is vital in preventing costly damages from occurring.

If you spot any gaps or cracks in your drywall seams, they may result from water damage. The first step is to inspect the walls and flooring near the area for signs of water.

If associated with a leak, try and stop it as soon as possible to reduce further damage. It’s best to contact a professional contractor who can assess the damage and recommend a repair solution.

Sometimes, drywall seams cracking might be due to structural shifting in the home or natural settling. If this happens, contact a structural engineer who can assess the foundation of your home and make any necessary repairs.

Keep an eye out for signs of drywall seams cracking; this could indicate water damage.

Will a Vacant Home Have Drywall Seams Cracking?

While a vacant home can have drywall seams cracking, several factors can cause this issue.

One of the most common causes is improper installation of the drywall. When installing new drywall panels, all seams must meet adequately and be secured to the wall studs.

If these steps are not followed correctly, cracking, and other damage can occur with age. Additionally, drywall seams that are not sealed properly can also cause cracks.

Temperature fluctuations and humidity changes in a vacant home can also contribute to drywall cracking due to the expansion and contraction of the material. If a home has been vacant for an extended period with no temperature or humidity control, drywall seams may begin to crack.

These factors can help determine if a home’s drywall seams are cracking due to improper installation or environmental causes.

The best way to prevent drywall seams from cracking due to improper installation is to ensure the drywall is installed correctly. It’s essential to hire experienced professional drywall contractors and tapers if you’re not comfortable doing it yourself.

Proper sealing of joints will also help prevent cracking from environmental causes. Taking the necessary steps ensures that your drywall seams stay intact even if you have a vacant home.
