Repairs and Causes

Wall cracking happens for a reason. Sometimes that reason is nothing to worry about. Other times, it points to serious foundation damage.

Here are several interior wall crack types, and what they mean:

  1. Non-Structural Settlement Cracks:
    Small cracks around crown molding, door corners, or windows that run vertically or diagonally are often non-structural and caused by normal foundation settling. These usually appear in weaker wall areas due to initial settling, and if they don’t expand over time, they’re not a major concern. However, if these cracks widen or change, it could indicate a more serious problem.

  2. Serious Structural Cracking:
    Horizontal cracks, especially when paired with bowing walls, signal more severe foundation issues. These cracks suggest lateral pressure from soil or hydrostatic forces, which can lead to major structural damage. If you see horizontal cracking, contact Helitech professionals for a thorough inspection to protect your home.

When you’re unsure about the cause of your wall cracking, it’s a good idea to have an expert take a glance. If this sounds like your situation, schedule a free consultation with us today.

Frequently Asked Questions

While both plaster and drywall cracks can signal foundation issues, their characteristics can differ. Plaster is more rigid, so it often shows hairline cracks or spiderweb patterns from minor shifts, while drywall might show straighter, more defined cracks along seams or at corners. However, the underlying cause like foundation settlement is often the same. The key is to observe the crack’s size, direction, and whether it’s expanding, regardless of the wall material.

Small, non-expanding hairline cracks are often cosmetic. However, any crack that is wider than a quarter-inch, horizontal, stair-stepping, or rapidly growing should be addressed promptly. These can indicate serious structural issues that can worsen over time, leading to more extensive and costly repairs.

It’s always best to get a professional evaluation to determine the root cause and prevent further damage.

Yes, absolutely. While foundation issues are a primary cause, interior cracks can also stem from excessive moisture or water damage. Leaking pipes, roof leaks, or high humidity can cause drywall or plaster to swell and contract, leading to cracks, bubbling, or discoloration. If you notice cracks accompanied by musty odors, stains, or dampness, it’s crucial to investigate for waterproofing issues in addition to potential foundation concerns.

Interior wall cracks are a significant indicator, but other signs of foundation issues include exterior brick cracks, bowing basement walls, uneven or sloping floors, sticking doors and windows, and gaps between walls and ceilings or floors. If you observe any combination of these symptoms, it’s highly recommended to schedule a professional foundation inspection to assess the structural integrity of your home.
