Why Do Cracked Walls Happen?
There are many reasons that cracked walls can happen. Usually, the reason is natural and nothing serious. But occasionally, things go wrong and your home could be in danger. Check out these reasons to see what your think caused your cracked wall.
Settling
This is the most common, and least worrisome, type of crack. This is what happens in new houses for the first year or so. It is completely normal and usually appears as hairline cracks around doorways.
Impact
If the wall suffered some sort of trauma then it could easily get cracked. While blunt force usually causes holes in drywall, in concrete, it may result in small cracks. Direct damage can always cause cracks.
Vacancy
If you leave a home empty for too long, even for a vacation, it can cause cracks in the walls. That’s why abandoned homes need so many repairs despite the home not being used. This is a different type of settling.
Bad Taping
When it comes to drywall, nothing can cause uglier cracks than a bad taping job. If the taping isn’t done right, to begin with, the seams will show, especially if the sheetrock wasn’t installed tightly. This is never a fun project to repair.
Learn to tape correctly before attempting to put up sheetrock. If you need to repair someone else’s bad taping job, then take a class or learn via tutorials online like the simple one below to find out more.
Leaks
Although water damage doesn’t always cause cracks and is a problem on its own, water can cause cracks. This is because it softens the wall and makes it more susceptible to tears as it swells and warps.
Water damage is the most expensive type of crack to fix because it usually involves removing the wall affected and getting to the bottom of the issue. This takes time and a lot of money, but it’s definitely necessary.
Structural Damage
This is the most serious type of crack and needs to be investigated right away. There are many things that can cause structural damage that can then cause cracks, such as termites, which will eat through your foundation from beneath the floors.
If the crack is wide or jagged, call a professional to make sure you don’t have a serious problem. If it’s a hairline crack near a door or window, then it’s probably fine and can be repaired normally on your own.
How To Fix Cracks In Walls
The way you fix cracked walls primarily depends on the type of wall you have. Plaster and drywall and the most common types of walls that need to be repaired regularly. Here’s what you need to know about each type.
Plaster
When it comes to plaster, here are a few types of cracks you may see and how to repair each of them. For a full guide on repairing plaster, take a look at this article which takes this info and goes more in-depth.
Hairline Cracks
If what you are dealing with is a hairline crack, your best bet is to remove the loose pieces and apply spackling to the affected area. You can apply a thin coat and let it dry before applying another if there is a need. After each coat, sand the area with sandpaper to see where you stand.
Wide Cracks
The first thing you need to do with a wide crack is press hard on each side to see if the crack is moving. If it is, the technique will be different. If it isn’t, then you need to apply plastering tape to the crack. Apply a thin coat of plaster underneath, then stick the tape to it.
Afterward, you apply to the top surface to even out the wall. Make sure that you apply more plaster to any side that’s deeper. Don’t forget to sand! Many people think they can get by without sanding, but not only does this make for a rough surface but it’s nearly impossible to paint an unsanded wall.
Moving Cracks
This is when things get complicated. Moving cracks aren’t as easy to repair because the problem isn’t on the surface. What you do here is dig out the moving side until you find solid plaster that does not move. It may be more work, but if you don’t fix it now, it will be even more work later.
Secure the loose side with plaster washers, drywall screws, and perforated discs. This will allow you to attach the loose plaster to the original lath. In a way, you’re starting over with the affected area. If you’re not a professional, you may want to watch a tutorial on how to fix moving cracks.
Drywall
The easiest way to repair drywall is to get a drywall patch kit. This includes everything you need to repair drywall as well as instructions on how to take care of each type of crack It’s a worthy investment for anyone with drywall.
Most drywall can be repaired by removing any loose tape and falling mud that is crumbling away from the wall. Then, sand the surface of the drywall where there is mud leftover. There’s no need to sand non-mudded areas.
After sanding, you can start filling the crack with drywall mud. Make it smooth with a drywall joint knife. Then place the tape on top of that mud. After you get the tape to stick, apply a thin layer of mud on top of it.
After this dries, sand it very well but don’t go deep enough that you compromise the tape’s adhesion. It can be easy to get lazy and opt for a simple spackling job but take will cover much better and last much longer.
Basement Wall Crack Repair
Most basement walls are made of concrete. Hopefully, the crack you have is vertical or diagonal cracks in concrete walls which is generally natural settling. If the crack is horizontal, it could mean something serious.
Contact a professional if the cracks seem strange or if they are wide. But if they are simple and vertical, namely hairline, then you should feel free to repair them on your own with one simple method.

Step 3: Sealing The Crack
Although epoxy works great for leveling, it can help to get a separate concrete sealer to ensure that the wall looks the same color throughout. It can also help with protecting it, so get a concrete sealer in a small can.
