How to Cope with Cracks in Walls and Ceilings?
By 
Walls and ceilings that have cracks are a common problem that most homes face at some point. They can be an eyesore, a sign of structural problems, or just a natural product of the building settling and getting older. To keep your home’s structure and look in good shape, you need to know what causes these cracks, how to stop them from happening, and how to fix them. In this piece, we’ll talk about what causes cracks in walls and ceilings, how to keep them from happening, and how to fix them properly.
Causes of Cracks in Walls and Ceilings
1. Settlement
Buildings settle over time as the ground beneath them changes. Walls and ceilings can get small cracks because of this. Most of the time, it’s not a big deal unless the cracks are big or there are other signs of structural problems.
2. Moisture
When water gets into a building, it can cause walls and ceilings to crack. Moisture makes the materials weaker, which makes them grow and contract, which can lead to cracks. This problem can be caused by leaking lines, roof problems, or a lack of waterproofing.
3. Changes in Temperature
Extreme changes in temperature can cause materials to grow and contract, which can cause cracks. This is especially common in places where the weather changes a lot.
4. Poor Construction
Cracks in walls and ceilings can be caused by bad planning or construction, like using low-quality materials or the wrong way to put them up. These cracks may show up soon after the building is built or over time.
5. Foundation Problems
Cracks in the walls and ceilings can be caused by problems with the foundation, like settling, moving, or not enough support. Cracks in the foundation usually need to be looked at and fixed by a professional.
How to Fix Wall and Ceiling Cracks
Cracks can be fixed in different ways, depending on how big they are and what caused them. Here are some common techniques:
Method 1: Patching
Cracks in walls and ceilings are often fixed by putting a patch over them. It involves filling the cracks with the right materials to fix the surface’s look and make it strong again. Here’s a look at the process of patching:
1. Preparation
The crack and the area around it need to be ready before the fixing process can begin. Do these things:
Clean the Surface: Take out any dirt, dust, or paint chips that are sticking out of the crack. Clean the area gently with a wire brush or scraper.
Make a V-shaped groove: For larger cracks, making a V-shaped groove along the length of the crack is helpful. This helps the repair material stick to a bigger area of the hole.
Sand the Surface: Smooth the sides of the crack and the area around it with sandpaper or a sanding block. This makes it easier for the repair material to stick.
To get rid of dust, use a damp cloth or sponge to wipe the area clean after sanding.
2. Choosing the fixing Material
The type and size of the crack will determine which fixing material to use. Here are some popular choices:
Spackling Compound: You can use spackling compound to fix small cracks and other small flaws on the surface. It is easy to use, dries quickly, and can be smoothed out with sandpaper.
Joint compound, which is also called “drywall mud,” is great for bigger cracks or places that need more work. It is thicker and covers better than the other one.
Patching Plaster: Patching plaster is a good way to fix cracks in plaster walls and ceilings that will last for a long time. It is often used for medium-sized to big cracks because it sticks well.
Self-Adhesive Mesh Tape: Using self-adhesive mesh tape along with joint compound can add extra support to larger cracks or places that tend to move.
3. How to Apply the Patching Material
The way to apply the patching material may be a little different based on what you choose. Just do these general things:
Spackling Compound: Use a putty knife to put the spackling compound right into the crack. Press it tightly into the crack and make sure it goes all the way down. Use the putty knife or a clean, wet sponge to smooth the surface. Let it dry fully, and if you need to, lightly sand it.
Joint compound: Spread some joint compound over the crack with a putty knife. Just go a little bit past the crack to make sure the whole area is covered. For larger cracks, press self-adhesive mesh tape tightly into the wet joint compound. Add another coat of joint compound on top of the tape and feather the edges so they blend in with the surface around them. Let it dry all the way, and if you need to, lightly sand between coats.
Mending Plaster: Follow the directions on the package to mix the mending plaster. Use a putty knife or a shovel to put the plaster right into the crack. Press it tightly into the crack and make sure the surface is smooth and even with the rest of the area. Let the plaster dry all the way, and if you need to, lightly sand it.
4. Finishing and painting
Once the patched area is dry and smooth, it is ready for the finishing touches and painting. Do these things:
Sanding: Use sandpaper with a fine grit to smooth the patched area and make it fit in with the rest of the surface. Get rid of any dust.
Priming: Paint a coat of primer over the fixed area to make it smooth and help the paint stick better. Follow the guidelines from the manufacturer for how long it should dry.
Painting: The last step is to paint the patched area so that it matches the rest of the wall or ceiling. Choose the right type of paint and apply as many coats as needed, giving each one enough time to dry in between.
Remember that it’s important to clean the surface, choose the right patching material, and use it properly if you want a repair that will last. If you’re not sure how to fix bigger or more complicated cracks, it’s best to get help from a professional to get the best results.
Method 2: Mud and Tape
People often use the “Tape and Mud” method to fix bigger cracks, especially in drywall or plaster. Using drywall joint tape and joint compound, you can make a strong and smooth fix with this method. Here’s a more in-depth look at the tape and mud method:
1. Preparation
The crack and the area around it need to be ready before the tape and mud process can begin. Do these things:
Clean the Surface: Take out any dirt, dust, or paint chips that are sticking out of the crack. Clean the area gently with a wire brush or scraper.
Make a V-shaped groove: For larger cracks, making a V-shaped groove along the length of the crack is helpful. This helps the joint cement and tape stick to a bigger area of the wood.
Sand the Surface: Smooth the sides of the crack and the area around it with sandpaper or a sanding block. This makes it easier for the joint cement and tape to stick together.
To get rid of dust, use a damp cloth or sponge to wipe the area clean after sanding.
2. How to Use Drywall Joint Tape
Drywall joint tape helps strengthen the crack and keep it from coming back. To put the tape on, do these things:
Cut the Tape. Measure the length of the crack and cut a piece of drywall joint tape that is a little longer than the crack.
Put the tape in place: Spread a thin layer of joint compound directly over the crack, going a little bit past the width of the crack. Press the drywall joint tape tightly and in the middle of the crack into the wet joint compound. Use a putty knife or a drywall knife to smooth out any air bubbles and make sure the tape is firmly in place.
Add more joint compound: Once the tape is in place, spread a thin layer of joint compound over it and feather the edges so they fit in with the surface around them. People often call this process “mudding.”
3. The Repair in the Mud
First Coat: Spread a thin layer of joint compound over the whole area where the tape is stuck with a wide putty knife or drywall knife. The goal is to cover the tape and make a layer of compound that is smooth and even. The application should go a little bit past the edges of the tape. Blend the edges in with the surface around them.
Second Coat: Once the first coat is dry, add a second coat of joint cement to cover a larger area. Smooth out the edges to make sure that the fix blends in with the rest of the surface. For the second coat, most people use a wider putty knife or sheetrock knife to get a bigger mud area.
More Coats: Depending on how big the crack is and how smooth you want it to be, you may need to add more coats of joint cement. Each coat should be wider than the one before it, and the sides should be blended to make a smooth finish. Let each coat dry before moving on to the next.
4. Sanding and Finishing
Sanding: Once the last coat of joint compound is dry, smooth the mended area with fine-grit sandpaper or a sanding block. Be careful not to damage the area around you as you sand. Get rid of any dust.
Priming: Paint a coat of primer over the area that was fixed to make a smooth surface and help the paint stick better. Follow the guidelines from the manufacturer for how long it should dry.
Painting: Finally, paint the patch so that it matches the rest of the wall or ceiling. Choose the right type of paint and apply as many coats as needed, giving each one enough time to dry in between.
Large cracks can be fixed well and for a long time with tape and mud. But it takes time and skill to get a result that is smooth and even. If you’re not sure if you can handle this kind of fix, it’s best to call a professional to make sure you get the best results.
Method 3: Injection
The “Injection” method is a good way to fix cracks in walls and ceilings, especially those that are caused by problems with the structure or base. In this method, a special material, such as epoxy or polyurethane, is injected into the crack to fix it and strengthen the structure. Here’s a more in-depth look at how injection works:
1. Checking and getting ready
It’s important to look at the crack and figure out how bad it is before starting the filling process. Find out if the crack is active or dormant. This will affect the choice of filler material and the way the crack is fixed.
Clean the Crack: Take out any dirt, dust, or paint chips that have fallen into the crack. Clean the area gently with a wire brush or scraper. This makes sure that the injection material sticks well.
V-Notch or Drill Holes: For cracks that are bigger or deeper, you may need to make a V-Notch or drill holes along the length of the crack. This makes room for the injection material to flow and makes sure it goes deeper.
2. Choosing the Material for the Injection
Epoxy: Injections of epoxy are good for structure cracks because they are strong and stick well. It is often used for surfaces made of concrete. Epoxy has a high compression strength and is perfect for cracks that need to be strengthened structurally.
Polyurethane: Injections of polyurethane can be used for both active and dormant cracks because they are flexible. It works especially well to fill holes in concrete and brick surfaces. When polyurethane is injected, it swells, filling holes and stopping water from getting in.
3. How an injection works
Installing Injection Ports: Depending on the size and shape of the crack, injection ports are usually set up along the length of the crack. These holes are where the material to be injected goes in.
Seal the Crack: Use the right sealant or glue to seal the crack on the surface. This will keep the inserted material from leaking out while the process is going on.
Injecting the Material: Use a gun or pump to insert the chosen material into the crack, starting at the lowest point or the injection port that is the farthest away. Fill the crack from the bottom up with the material, applying even pressure. Keep injecting until the material comes out of the port next to it or until the crack is filled.
After the injection is done, keep an eye on the crack to make sure the material heals and hardens the right way. Follow the curing time instructions given by the maker.
4. Finishing
Restoring the surface: Once the material that was inserted has completely hardened, remove the injection ports and any extra material that sticks out from the surface. Use a knife, a scraper, or sandpaper to make the surface smooth and the same height as the rest of the area.
Surface Preparation: Clean the area that needs to be fixed to get rid of any dust or dirt. This makes sure that any treatments or finishes that come after will stick well.
Paint or Finish: Depending on the type of surface, you may need to repaint or add a finish to make it look like the rest of the room. Follow the steps for painting or finishing that are right for the material.
Cracks in structures can be fixed with injection fixes, which work well and last a long time. But because of the special tools and materials needed, it is best to talk to a professional or an expert with experience in injection repairs, especially if there are major structural problems or cracks that are hard to fix. They can correctly figure out what’s going on and give you the best injection method for your needs.
Method 4: Evaluation by a professional
When dealing with cracks in walls and ceilings, the “Professional Assessment” step is a very important one. Even though you can fix some small cracks on your own, it is important to get a professional to do a full evaluation, especially if the cracks are big or keep coming back. Here’s a more in-depth look at the process of professional assessment:
1. How to Find a Skilled Professional
Look for contractors with a lot of experience. Ask friends, family, or neighbors who have dealt with similar problems for suggestions. You could also look through online directories or talk to local building and repair companies to find experienced contractors who assess and fix cracks.
Check their credentials: Make sure the professionals you’re thinking about are licensed, protected, and have a good name in the field. Check to see if they have any certifications or are part of professional groups that prove their skills and knowledge.
2. The first check
On-Site Visit: Get in touch with the chosen professional and set up a visit on-site. During the inspection, the professional will look at the cracks in your walls and ceilings to see how big they are, how bad they are, and if there are any structural problems that could be caused by them.
Thorough Examination: The professional will do a thorough examination of the damaged areas, taking into account things like the patterns of cracks, the level of moisture, the building materials underneath, and any signs of movement or settling. They might use tools and equipment like moisture meters, thermal imaging cameras, or crack gauges to help them do their job.
3. Getting to the Root of the Problem
Determine the Cause: The expert will look into what caused the cracks in order to make a correct evaluation. They will look at typical causes like settlement, foundation problems, water getting in, stress on the structure, or bad building practices.
Extra Tests: In some situations, the professional may need to do more tests to find out more. This could include tests of the soil, geotechnical studies, or structural engineering evaluations of the building’s stability.
4. Report with Specifics and Suggestions
Assessment Report: The professional will give you a full assessment report after the inspection. This report will explain what was found during the inspection, including what caused the cracks, how bad they are, and if there are any structural issues. It may also include suggestions for repairs, safety steps, or more research if they are needed.
Options for repairs: Based on the report of the assessment, the professional will offer repairs that are right for your situation. They will list the pros and cons of each choice, taking into account things like cost, how long it will last, and how it will affect the building’s structure.
Cost estimates: The professional may give you an idea of how much the suggested fixes will cost. This will help you figure out how it will affect your finances and make plans.
5. Making a choice
Review the Assessment: Take the time to look over the professional’s assessment report and suggestions. If you don’t understand something, you should ask for more information.
Think About What Experts Say: When making decisions about the fixes, think about what the professional knows and how good they are at what they do. They have the experience and knowledge of structure problems to help you figure out the best way to move forward.
Budget and set priorities: Look at how much money you have and rank the suggested repairs by how important they are to the building’s structure and how quickly they need to be done.
By having a professional do the assessment, you can learn a lot about what caused the cracks and how bad they are. They can also give you advice on the best ways to fix them. This method makes sure that the repairs fix the problem at its source and last for a long time. This makes it less likely that the cracks will come back in the future.
Steps to take to stop it
Even though some causes of cracks are unavoidable, there are things you can do to keep them from happening:
Regular Maintenance:
Check your property often for signs of damage or cracks so you can fix them as soon as possible. Take care of any problems right away so they don’t get worse.
Drainage
Make sure your home has a well-kept drainage system that moves water away from the foundation. This reduces the number of cracks caused by water.
Temperature and Humidity Control
Make sure your home is always the same temperature and humidity level. Use proper insulation and airflow to lessen the effect of changes in temperature.
Professional Construction
When building or remodeling, hire professionals with a lot of experience who know how to do things right and use high-quality products. This can help stop cracks that are caused by bad building.
Foundation upkeep
Keep an eye on how your foundation is doing. Talk to a professional foundation contractor as soon as you notice any signs of settling or moving.
Walls and ceilings can sometimes get cracks, but you shouldn’t ignore them. Understanding what causes cracks, taking steps to stop them, and fixing them right away can help keep your home’s structure and appearance in good shape. By taking the right steps and getting help from a professional when needed, you can deal with cracks and make sure that your walls and ceilings will be stable for a long time.
