The size of the crack is a good indicator of its severity. A singular hairline crack on interior muren shouldn’t be a cause for concern. However, if the crack is more than ¼ inch wide, it could be a sign of a more serious issue. Additionally, if the crack continues to grow over time, it’s important to take action.
The Filling Process
If you’ve determined that the crack is not serious, you can simply fill it with spackling paste, allow it to dry, and then repaint. However, if the crack is wider than ¼ inch, it’s important to take the following steps:
- Use a putty knife to remove any loose debris from the crack
- Fill the crack with joint compound or spackling paste
- Use a putty knife to smooth the surface
- Allow the compound to dry completely
- Sand the surface until it’s smooth
- Repaint the area
Improvement and Home Maintenance
While filling a crack in your wall may seem like a simple process, it’s important to address the underlying issue to prevent the crack from reappearing. Here are some tips to improve and maintain your home:
- Keep an eye on the humidity levels in your home to prevent moisture buildup
- Address any drainage issues around your home to prevent water from seeping into your foundation
- Regularly inspect your home’s foundation for signs of settling or subsidence
- Hire a professional to inspect your home’s structure if you notice any significant cracks or other issues
Remember, while a crack in your wall may seem like a minor issue, it could be a sign of a more serious problem. By understanding the severity of wall cracks and taking the necessary steps to address them, you can keep your home in top condition.
Why Your Old Home is Prone to Cracks
Your home is old, and that could be the cause of the cracks you’re seeing. Older homes were constructed using lime, shifting ground, and other materials that are less flexible than modern cement renders and mortars. As a result, these homes are more prone to structural failure and cracks.
Temperature and Humidity Changes
Temperature changes and variations in humidity levels can cause your old home’s structure to shrink and swell over a prolonged period of time. This can result in cracks appearing on the walls, especially in newly plastered walls that experience hairline cracks as they dry out.
Immediate and Wider Causes
In some cases, cracks can occur due to immediate causes such as faulty taping of drywall or settling of the ground. However, in older homes, cracks may be caused by wider issues such as the settling of the house over time or the growth of tree roots.
If you notice cracks in your old home, it’s important to consult with an experienced professional, such as an Ian Chartered Surveyor like Haynes House Manuals. Depending on the severity of the crack, you may need to patch it up with spackling paste or fill it with a fine patch. However, if the crack is significant or wider than an inch, it’s best to consult with a professional to ensure the structural integrity of your home is not compromised.
In summary, your old home is prone to cracks due to its age, construction materials, and exposure to temperature and humidity changes. While some cracks may be superficial and easily fixed, others may indicate a more significant issue and require immediate attention from a professional.
Why a New Build May Develop Wall Cracks
Not all wall cracks in a new build are a cause for concern. Here are some factors to consider:
- Size: If the cracks are less than 1/8 inch wide, it’s typically considered normal and not a cause for worry.
- Location: Horizontal cracks are more concerning than vertical cracks, as they can signal a more significant issue.
- Effects: If you notice additional effects, such as water damage or a sagging ceiling, it may be a sign of a more significant problem.
Addressing Wall Cracks in a New Build
If you’ve noticed wall cracks in your new build, here are some steps you can take:

Why Leaving Your Home Vacant Can Cause Wall Cracks
Leaving your home vacant for a long period of time can have a significant impact on the walls. Fluctuations in temperature and humidity levels can cause framing members and drywall to expand and contract, resulting in cracking. This can be especially true in older homes that were not built to be climate controlled.
Protecting Your Walls
There are numerous methods to protect your walls from excess moisture and temperature changes. Utilizing a dehumidifier can help keep the air dry and prevent wet conditions that can affect the walls directly. Applying a waterproofing compound to the walls can also help prevent moisture from penetrating the walls.
Preventing Improper Wall Cracks
Properly addressing wall cracks is important to prevent them from becoming a bigger issue. Depending on the types of cracks found, different methods may be utilized to prevent them from getting worse. For example, small, thin cracks can be set with a compound, while larger cracks may require the use of a block or other strong material.
The Best Time to Address Wall Cracks
The best time to address wall cracks is as soon as they are discovered. This will give you the best chance of preventing them from becoming a bigger issue. If left untreated, wall cracks can actually weaken the structure of your home and make it less safe to live in.
The Unique Potential of Modern Building Materials
Modern building materials offer a range of options for preventing wall cracks. These materials are designed to be stronger and more durable than traditional materials, making them better suited for protecting your walls. Additionally, modern materials can be utilized to create a complete barrier against moisture and other potential causes of wall cracks.
Why Faulty Taping of Drywall Can Create Cracks in Your Walls
Faulty taping of drywall is a common reason for cracks in walls. It happens when the tape used to cover the seams between drywall sheets is not properly installed or is of poor quality. This can lead to the tape pulling away from the drywall, leaving a gap that can eventually turn into a crack.
What to Do if You Notice Cracks in Your Walls
If you notice cracks in your walls, it’s important to take action to prevent them from getting worse. Here are some steps you can take:
- Check the rest of the area: Look for other cracks or signs of damage in the same area.
- Determine the cause: Try to figure out what caused the cracks in the first place.
- Fix the problem: Once you’ve determined the cause, take steps to fix the problem. If it’s faulty taping of drywall, you may need to remove the tape and start over.
- Cover the cracks: Use a high-quality spackle or joint compound to cover the cracks and achieve a smooth finish.
- Allow enough drying time: Make sure the spackle or joint compound is completely dry before painting or wallpapering over it.
Why Proper Taping of Drywall is Essential for Your Home’s Structure
Proper taping of drywall is essential for your home’s structure because it:
- Creates a strong and smooth surface for finishing.
- Helps to resist cracks and other damage.

Adding climbing plants to your wall can be a beautiful addition, but it’s important to understand the potential damage and maintenance required. By following these tips, you can help ensure a better outcome for both your climbers and your wall.
Why Walls Crack: The Ground Beneath Your Feet
Settlement cracks occur when the ground beneath a structure shifts or settles. This can happen for a variety of reasons, including:
- The weight of the building itself
- Weight imposed by furniture and other objects
- Changes in moisture levels in the soil
- Natural movement of the earth’s crust
How Settlement Affects Buildings
When a building settles, it can cause the foundation to shift and settle as well. This can lead to problems such as:
- Cracking in walls and masonry
- Structurele schade
- Oneffen vloeren
- Doors and windows that no longer open or close properly
How Buildings Adjust to Settlement
While settlement is a natural occurrence, buildings are designed to accommodate for it. Here are some ways that structures adjust to settlement:
- Foundations are designed to be flexible, allowing for movement without harmfully affecting the building’s structure.
- Joints are provided between different parts of the building, allowing for movement without causing cracking or other damage.
- Walls and other parts of the building are constructed with materials that can compress and settle without cracking or breaking.
When Settlement Becomes a Problem
While minor settlement is normal and happens periodically, major settlement can cause serious problems for homeowners. Here are some signs that settlement may be becoming a problem:
- Cracks in walls or masonry that grow over time
- Doors and windows that no longer open or close properly
- Oneffen vloeren
- Hairline cracks in the foundation
If you notice any of these signs, it’s important to have your home inspected by a professional to determine the cause of the problem and the best course of action.
Subsidence: The Homeowner’s Worst Nightmare
Subsidence refers to the sinking or settling of the ground beneath a building, causing it to sink or become unstable. This can result in cracks appearing in walls, floors, and doors, destabilising the support of the building and potentially causing catastrophic visual and financial issues for homeowners.
How Does Subsidence Occur Naturally?
Subsidence can occur naturally as a result of the settlement, such as in the following scenarios:
- Foundations in new builds and extensions will settle under their own weight over time, which can result in hairline cracks. The same can happen to freshly plastered interior walls that need to dry out over time.
- Frosts can cause subsoils to freeze and expand, which can lead to the ground sinking when it thaws.
- Squelchy subsoils that encourage heave when they dry out.
What are the Effects of Subsidence?
The effects of subsidence can be devastating for homeowners, including:
- Cracking walls, floors, and doors
- Movement in the building, causing doors and windows to stick or not close properly
- The ability of the building to support itself is compromised, which can lead to structural damage and safety concerns
- The worst-case scenario is that the building may need to be demolished and rebuilt
How to Deal with Subsidence?
Dealing with subsidence needs to be done in a timely and professional manner to avoid financial problems. Here are some steps homeowners can take:
- If you suspect subsidence, contact a professional to assess the problem and advise on the best course of action.
