No, not all horizontal drywall cracks are bad. Many are harmless cosmetic issues like minor house settling, humidity changes, or failing joint tape. However, they can be serious red flags if they are deep, progressively widening, or accompanied by stuck doors and windows.
Foundation movement: Uneven settling of the foundation can put stress on walls, causing them to crack horizontally. This is due to poor soil conditions, moisture issues or changes in water drainage around the house. While horizontal cracks may be more commonly associated with newer homes, older homes are not exempt.
Horizontal cracks are significantly worse than vertical cracks, indicating serious structural failure due to external pressure (often soil/water) that can cause wall collapse. Vertical cracks are usually caused by minor, typical settling or shrinkage. Horizontal cracks warrant immediate professional inspection.
When the soil around the foundation becomes saturated, it exerts pressure on the walls, leading to horizontal cracking. Horizontal cracks can be a severe issue, as they can cause structural damage that may compromise the integrity of the entire building.
Horizontal cracks cost an average of $5,000 and up to about $10,000 in Southern California to repair and stabilize. They can cause immense damage and even house collapse if you don't take care of them, so you should factor this foundation repair cost into your purchase price to ensure the house is worth buying.
Factors that decrease property value the most fall into three main categories: location issues, structural damage, and poor neighborhood conditions. These factors can collectively slash a property’s value by 5% to 30% or more.
Horizontal or step cracks
Repairing these cracks involves epoxy or polyurethane injections plus reinforcement, such as carbon fiber straps or wall anchors, with costs ranging from $1,000 to $5,000+ per crack. Addressing these cracks early is important to prevent structural compromise and expensive future repairs.
Cold weather slows soil movement, making winter one of the best foundation inspection and repair times. Unlike spring and summer, when moisture and temperature changes cause shifting, winter's stability allows professionals to assess damage and implement long-lasting solutions accurately.
A bad foundation crack is typically wider than 1/8 inch (or a nickel), spans horizontally across walls, follows a stair-step pattern, or shows signs of active growth. These structural cracks indicate major soil pressure or uneven settling, especially if they are deeper at one end.
Structural drywall cracks are typically wider than 1/8 inch, run horizontally or diagonally (often at 45-degree angles), or appear above door/window frames and in multiple areas at once. Unlike superficial cracks, structural issues are often accompanied by sticking doors, sagging ceilings, or stair-step patterns in masonry.
To repair horizontal foundation cracks, one of the most effective techniques is epoxy injection. This process bonds the concrete back together, restoring its original strength and structural integrity.
For residential walls, you should generally hang drywall horizontally. This method ties together more studs for greater structural strength, reduces the total linear footage of seams, and places the main tapered joints at a convenient waist height for easier taping and mudding.
How To Fix Cracks in Drywall
Horizontal cracks in walls usually indicate serious structural stress or foundation bowing caused by outside pressure. In foundation or basement walls, this is almost always a red flag. In upper-level drywall, it might just be a shifting joint, but it warrants monitoring.
In short: Yes, horizontal foundation cracks are almost always bad. Unlike typical vertical settlement cracks, horizontal cracks indicate severe lateral pressure from expanding soil or water. Even if they look like small "hairline" fractures, they require immediate attention.
Normal settling cracks in houses are typically thin, shallow, and stable over time. They often appear in drywall or plaster as a home adjusts to minor shifts in the foundation.
Yes, you can sell a home with foundation cracks, but you'll need to meet disclosure requirements. It's necessary to inform potential buyers about the issue. However, keep in mind that foundation problems might raise concerns for buyers. They might request a price reduction or ask you to fix the issues before purchase.
So, can you live in a house during foundation repair? In most cases, absolutely. With the right planning and support, you can keep on going about your daily routine while we take care of restoring your home's structural integrity.
Water is the most common enemy of concrete surfaces. When water penetrates the surface of concrete, it can cause it to crack and weaken. This is especially true in colder climates where water can freeze and expand, creating even more damage.
Structural foundation cracks indicate a threat to your home's stability, often caused by soil pressure or uneven settling. You should be concerned if a crack is horizontal, wider than 1/8 of an inch, shaped like a staircase, actively growing, or accompanied by sticking doors and sloping floors.
Common Ways to Fix Horizontal Foundation Cracks
I-Beams (Steel Beams): These are installed vertically inside your basement. They brace the wall and keep it from bowing anymore. Deadman Anchors: These are placed in the yard and attached to the inside wall. They apply force from the outside to hold the wall in place.
If you need a small drywall crack repair, chances are the repair costs will also be small. However, your costs will be higher if the crack requires removing and replacing a large amount of drywall to complete the repair.
While vertical cracks are sometimes harmless, horizontal cracks typically indicate structural stress. Cracks to pay special attention to include: Cracks with Bowing Walls. Wide Horizontal Cracks.
